+
+Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
+their respective handler.
+
+The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
+
+* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
+* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
+* URL hosts, paths and query values can have variables with an optional regular expression.
+* Registered URLs can be built, or "reversed", which helps maintaining references to resources.
+* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.

+
+## Install
+
+With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain:
+
+```sh
+go get -u github.com/gorilla/mux
+```
+
+## Examples
+
+Let's start registering a couple of URL paths and handlers:
+
+```go
+func main() {
+    r := mux.NewRouter()
+    r.HandleFunc("/", HomeHandler)
+    r.HandleFunc("/products", ProductsHandler)
+    r.HandleFunc("/articles", ArticlesHandler)
+    http.Handle("/", r)
+}
+```
+
+Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters.
+
+Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/products/{key}", ProductHandler)
+r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+```
+
+The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
+
+```go
+func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
+    vars := mux.Vars(r)
+    w.WriteHeader(http.StatusOK)
+    fmt.Fprintf(w, "Category: %v\n", vars["category"])
+}
+```
+
+And this is all you need to know about the basic usage. More advanced options are explained below.
+
+### Matching Routes
+
+Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables:
+
+```go
+r := mux.NewRouter()
+// Only matches if domain is "www.example.com".
+r.Host("www.example.com")
+// Matches a dynamic subdomain.
+r.Host("{subdomain:[a-z]+}.example.com")
+```
+
+There are several other matchers that can be added. To match path prefixes:
+
+```go
+r.PathPrefix("/products/")
+```
+
+...or HTTP methods:
+
+```go
+r.Methods("GET", "POST")
+```
+
+...or URL schemes:
+
+```go
+r.Schemes("https")
+```
+
+...or header values:
+
+```go
+r.Headers("X-Requested-With", "XMLHttpRequest")
+```
+
+...or query values:
+
+```go
+r.Queries("key", "value")
+```
+
+...or to use a custom matcher function:
+
+```go
+r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
+    return r.ProtoMajor == 0
+})
+```
+
+...and finally, it is possible to combine several matchers in a single route:
+
+```go
+r.HandleFunc("/products", ProductsHandler).
+  Host("www.example.com").
+  Methods("GET").
+  Schemes("http")
+```
+
+Routes are tested in the order they were added to the router. If two routes match, the first one wins:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/specific", specificHandler)
+r.PathPrefix("/").Handler(catchAllHandler)
+```
+
+Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting".
+
+For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it:
+
+```go
+r := mux.NewRouter()
+s := r.Host("www.example.com").Subrouter()
+```
+
+Then register routes in the subrouter:
+
+```go
+s.HandleFunc("/products/", ProductsHandler)
+s.HandleFunc("/products/{key}", ProductHandler)
+s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+```
+
+The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route.
+
+Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter.
+
+There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths:
+
+```go
+r := mux.NewRouter()
+s := r.PathPrefix("/products").Subrouter()
+// "/products/"
+s.HandleFunc("/", ProductsHandler)
+// "/products/{key}/"
+s.HandleFunc("/{key}/", ProductHandler)
+// "/products/{key}/details"
+s.HandleFunc("/{key}/details", ProductDetailsHandler)
+```
+
+
+### Static Files
+
+Note that the path provided to `PathPrefix()` represents a "wildcard": calling
+`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
+request that matches "/static/\*". This makes it easy to serve static files with mux:
+
+```go
+func main() {
+    var dir string
+
+    flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
+    flag.Parse()
+    r := mux.NewRouter()
+
+    // This will serve files under http://localhost:8000/static/<filename>
+    r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
+
+    srv := &http.Server{
+        Handler:      r,
+        Addr:         "127.0.0.1:8000",
+        // Good practice: enforce timeouts for servers you create!
+        WriteTimeout: 15 * time.Second,
+        ReadTimeout:  15 * time.Second,
+    }
+
+    log.Fatal(srv.ListenAndServe())
+}
+```
+
+### Serving Single Page Applications
+
+Most of the time it makes sense to serve your SPA on a separate web server from your API,
+but sometimes it's desirable to serve them both from one place. It's possible to write a simple
+handler for serving your SPA (for use with React Router's [BrowserRouter](https://reacttraining.com/react-router/web/api/BrowserRouter) for example), and leverage
+mux's powerful routing for your API endpoints.
+
+```go
+package main
+
+import (
+	"encoding/json"
+	"log"
+	"net/http"
+	"os"
+	"path/filepath"
+	"time"
+
+	"github.com/gorilla/mux"
+)
+
+// spaHandler implements the http.Handler interface, so we can use it
+// to respond to HTTP requests. The path to the static directory and
+// path to the index file within that static directory are used to
+// serve the SPA in the given static directory.
+type spaHandler struct {
+	staticPath string
+	indexPath  string
+}
+
+// ServeHTTP inspects the URL path to locate a file within the static dir
+// on the SPA handler. If a file is found, it will be served. If not, the
+// file located at the index path on the SPA handler will be served. This
+// is suitable behavior for serving an SPA (single page application).
+func (h spaHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
+    // get the absolute path to prevent directory traversal
+	path, err := filepath.Abs(r.URL.Path)
+	if err != nil {
+        // if we failed to get the absolute path respond with a 400 bad request
+        // and stop
+		http.Error(w, err.Error(), http.StatusBadRequest)
+		return
+	}
+
+    // prepend the path with the path to the static directory
+	path = filepath.Join(h.staticPath, path)
+
+    // check whether a file exists at the given path
+	_, err = os.Stat(path)
+	if os.IsNotExist(err) {
+		// file does not exist, serve index.html
+		http.ServeFile(w, r, filepath.Join(h.staticPath, h.indexPath))
+		return
+	} else if err != nil {
+        // if we got an error (that wasn't that the file doesn't exist) stating the
+        // file, return a 500 internal server error and stop
+		http.Error(w, err.Error(), http.StatusInternalServerError)
+		return
+	}
+
+    // otherwise, use http.FileServer to serve the static dir
+	http.FileServer(http.Dir(h.staticPath)).ServeHTTP(w, r)
+}
+
+func main() {
+	router := mux.NewRouter()
+
+	router.HandleFunc("/api/health", func(w http.ResponseWriter, r *http.Request) {
+		// an example API handler
+		json.NewEncoder(w).Encode(map[string]bool{"ok": true})
+	})
+
+	spa := spaHandler{staticPath: "build", indexPath: "index.html"}
+	router.PathPrefix("/").Handler(spa)
+
+	srv := &http.Server{
+		Handler: router,
+		Addr:    "127.0.0.1:8000",
+		// Good practice: enforce timeouts for servers you create!
+		WriteTimeout: 15 * time.Second,
+		ReadTimeout:  15 * time.Second,
+	}
+
+	log.Fatal(srv.ListenAndServe())
+}
+```
+
+### Registered URLs
+
+Now let's see how to build registered URLs.
+
+Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
+  Name("article")
+```
+
+To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do:
+
+```go
+url, err := r.Get("article").URL("category", "technology", "id", "42")
+```
+
+...and the result will be a `url.URL` with the following path:
+
+```
+"/articles/technology/42"
+```
+
+This also works for host and query value variables:
+
+```go
+r := mux.NewRouter()
+r.Host("{subdomain}.example.com").
+  Path("/articles/{category}/{id:[0-9]+}").
+  Queries("filter", "{filter}").
+  HandlerFunc(ArticleHandler).
+  Name("article")
+
+// url.String() will be "http://news.example.com/articles/technology/42?filter=gorilla"
+url, err := r.Get("article").URL("subdomain", "news",
+                                 "category", "technology",
+                                 "id", "42",
+                                 "filter", "gorilla")
+```
+
+All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match.
+
+Regex support also exists for matching Headers within a route. For example, we could do:
+
+```go
+r.HeadersRegexp("Content-Type", "application/(text|json)")
+```
+
+...and the route will match both requests with a Content-Type of `application/json` as well as `application/text`
+
+There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do:
+
+```go
+// "http://news.example.com/"
+host, err := r.Get("article").URLHost("subdomain", "news")
+
+// "/articles/technology/42"
+path, err := r.Get("article").URLPath("category", "technology", "id", "42")
+```
+
+And if you use subrouters, host and path defined separately can be built as well:
+
+```go
+r := mux.NewRouter()
+s := r.Host("{subdomain}.example.com").Subrouter()
+s.Path("/articles/{category}/{id:[0-9]+}").
+  HandlerFunc(ArticleHandler).
+  Name("article")
+
+// "http://news.example.com/articles/technology/42"
+url, err := r.Get("article").URL("subdomain", "news",
+                                 "category", "technology",
+                                 "id", "42")
+```
+
+### Walking Routes
+
+The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router. For example,
+the following prints all of the registered routes:
+
+```go
+package main
+
+import (
+	"fmt"
+	"net/http"
+	"strings"
+
+	"github.com/gorilla/mux"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+	return
+}
+
+func main() {
+	r := mux.NewRouter()
+	r.HandleFunc("/", handler)
+	r.HandleFunc("/products", handler).Methods("POST")
+	r.HandleFunc("/articles", handler).Methods("GET")
+	r.HandleFunc("/articles/{id}", handler).Methods("GET", "PUT")
+	r.HandleFunc("/authors", handler).Queries("surname", "{surname}")
+	err := r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
+		pathTemplate, err := route.GetPathTemplate()
+		if err == nil {
+			fmt.Println("ROUTE:", pathTemplate)
+		}
+		pathRegexp, err := route.GetPathRegexp()
+		if err == nil {
+			fmt.Println("Path regexp:", pathRegexp)
+		}
+		queriesTemplates, err := route.GetQueriesTemplates()
+		if err == nil {
+			fmt.Println("Queries templates:", strings.Join(queriesTemplates, ","))
+		}
+		queriesRegexps, err := route.GetQueriesRegexp()
+		if err == nil {
+			fmt.Println("Queries regexps:", strings.Join(queriesRegexps, ","))
+		}
+		methods, err := route.GetMethods()
+		if err == nil {
+			fmt.Println("Methods:", strings.Join(methods, ","))
+		}
+		fmt.Println()
+		return nil
+	})
+
+	if err != nil {
+		fmt.Println(err)
+	}
+
+	http.Handle("/", r)
+}
+```
+
+### Graceful Shutdown
+
+Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
+
+```go
+package main
+
+import (
+    "context"
+    "flag"
+    "log"
+    "net/http"
+    "os"
+    "os/signal"
+    "time"
+
+    "github.com/gorilla/mux"
+)
+
+func main() {
+    var wait time.Duration
+    flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
+    flag.Parse()
+
+    r := mux.NewRouter()
+    // Add your routes as needed
+
+    srv := &http.Server{
+        Addr:         "0.0.0.0:8080",
+        // Good practice to set timeouts to avoid Slowloris attacks.
+        WriteTimeout: time.Second * 15,
+        ReadTimeout:  time.Second * 15,
+        IdleTimeout:  time.Second * 60,
+        Handler: r, // Pass our instance of gorilla/mux in.
+    }
+
+    // Run our server in a goroutine so that it doesn't block.
+    go func() {
+        if err := srv.ListenAndServe(); err != nil {
+            log.Println(err)
+        }
+    }()
+
+    c := make(chan os.Signal, 1)
+    // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
+    // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
+    signal.Notify(c, os.Interrupt)
+
+    // Block until we receive our signal.
+    <-c
+
+    // Create a deadline to wait for.
+    ctx, cancel := context.WithTimeout(context.Background(), wait)
+    defer cancel()
+    // Doesn't block if no connections, but will otherwise wait
+    // until the timeout deadline.
+    srv.Shutdown(ctx)
+    // Optionally, you could run srv.Shutdown in a goroutine and block on
+    // <-ctx.Done() if your application should wait for other services
+    // to finalize based on context cancellation.
+    log.Println("shutting down")
+    os.Exit(0)
+}
+```
+
+### Middleware
+
+Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
+Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
+
+Mux middlewares are defined using the de facto standard type:
+
+```go
+type MiddlewareFunc func(http.Handler) http.Handler
+```
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+```go
+func loggingMiddleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        // Do stuff here
+        log.Println(r.RequestURI)
+        // Call the next handler, which can be another middleware in the chain, or the final handler.
+        next.ServeHTTP(w, r)
+    })
+}
+```
+
+Middlewares can be added to a router using `Router.Use()`:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+r.Use(loggingMiddleware)
+```
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+```go
+// Define our struct
+type authenticationMiddleware struct {
+	tokenUsers map[string]string
+}
+
+// Initialize it somewhere
+func (amw *authenticationMiddleware) Populate() {
+	amw.tokenUsers["00000000"] = "user0"
+	amw.tokenUsers["aaaaaaaa"] = "userA"
+	amw.tokenUsers["05f717e5"] = "randomUser"
+	amw.tokenUsers["deadbeef"] = "user0"
+}
+
+// Middleware function, which will be called for each request
+func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+        token := r.Header.Get("X-Session-Token")
+
+        if user, found := amw.tokenUsers[token]; found {
+        	// We found the token in our map
+        	log.Printf("Authenticated user %s\n", user)
+        	// Pass down the request to the next middleware (or final handler)
+        	next.ServeHTTP(w, r)
+        } else {
+        	// Write an error and stop the handler chain
+        	http.Error(w, "Forbidden", http.StatusForbidden)
+        }
+    })
+}
+```
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+
+amw := authenticationMiddleware{}
+amw.Populate()
+
+r.Use(amw.Middleware)
+```
+
+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
+
+### Handling CORS Requests
+
+[CORSMethodMiddleware](https://godoc.org/github.com/gorilla/mux#CORSMethodMiddleware) intends to make it easier to strictly set the `Access-Control-Allow-Methods` response header.
+
+* You will still need to use your own CORS handler to set the other CORS headers such as `Access-Control-Allow-Origin`
+* The middleware will set the `Access-Control-Allow-Methods` header to all the method matchers (e.g. `r.Methods(http.MethodGet, http.MethodPut, http.MethodOptions)` -> `Access-Control-Allow-Methods: GET,PUT,OPTIONS`) on a route
+* If you do not specify any methods, then:
+> _Important_: there must be an `OPTIONS` method matcher for the middleware to set the headers.
+
+Here is an example of using `CORSMethodMiddleware` along with a custom `OPTIONS` handler to set all the required CORS headers:
+
+```go
+package main
+
+import (
+	"net/http"
+	"github.com/gorilla/mux"
+)
+
+func main() {
+    r := mux.NewRouter()
+
+    // IMPORTANT: you must specify an OPTIONS method matcher for the middleware to set CORS headers
+    r.HandleFunc("/foo", fooHandler).Methods(http.MethodGet, http.MethodPut, http.MethodPatch, http.MethodOptions)
+    r.Use(mux.CORSMethodMiddleware(r))

+    if r.Method == http.MethodOptions {
+        return
+    }
+
+    w.Write([]byte("foo"))
+}
+```
+
+And an request to `/foo` using something like:
+
+```bash
+curl localhost:8080/foo -v
+```
+
+Would look like:
+
+```bash
+*   Trying ::1...

+< Content-Length: 3
+< Content-Type: text/plain; charset=utf-8
+< 
+* Connection #0 to host localhost left intact
+foo
+```
+
+### Testing Handlers
+
+Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
+
+First, our simple HTTP handler:
+
+```go
+// endpoints.go
+package main
+
+func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
+    // A very simple health check.
+    w.Header().Set("Content-Type", "application/json")
+    w.WriteHeader(http.StatusOK)
+
+    // In the future we could report back on the status of our DB, or our cache
+    // (e.g. Redis) by performing a simple PING, and include them in the response.
+    io.WriteString(w, `{"alive": true}`)
+}
+
+func main() {
+    r := mux.NewRouter()
+    r.HandleFunc("/health", HealthCheckHandler)
+
+    log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+
+Our test code:
+
+```go
+// endpoints_test.go
+package main
+
+import (
+    "net/http"
+    "net/http/httptest"
+    "testing"
+)
+
+func TestHealthCheckHandler(t *testing.T) {
+    // Create a request to pass to our handler. We don't have any query parameters for now, so we'll
+    // pass 'nil' as the third parameter.
+    req, err := http.NewRequest("GET", "/health", nil)
+    if err != nil {
+        t.Fatal(err)
+    }
+
+    // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
+    rr := httptest.NewRecorder()
+    handler := http.HandlerFunc(HealthCheckHandler)
+
+    // Our handlers satisfy http.Handler, so we can call their ServeHTTP method
+    // directly and pass in our Request and ResponseRecorder.
+    handler.ServeHTTP(rr, req)
+
+    // Check the status code is what we expect.
+    if status := rr.Code; status != http.StatusOK {
+        t.Errorf("handler returned wrong status code: got %v want %v",
+            status, http.StatusOK)
+    }
+
+    // Check the response body is what we expect.
+    expected := `{"alive": true}`
+    if rr.Body.String() != expected {
+        t.Errorf("handler returned unexpected body: got %v want %v",
+            rr.Body.String(), expected)
+    }
+}
+```
+
+In the case that our routes have [variables](#examples), we can pass those in the request. We could write
+[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
+possible route variables as needed.
+
+```go
+// endpoints.go
+func main() {
+    r := mux.NewRouter()
+    // A route with a route variable:
+    r.HandleFunc("/metrics/{type}", MetricsHandler)
+
+    log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+
+Our test file, with a table-driven test of `routeVariables`:
+
+```go
+// endpoints_test.go
+func TestMetricsHandler(t *testing.T) {
+    tt := []struct{
+        routeVariable string
+        shouldPass bool
+    }{
+        {"goroutines", true},
+        {"heap", true},
+        {"counters", true},
+        {"queries", true},
+        {"adhadaeqm3k", false},
+    }
+
+    for _, tc := range tt {
+        path := fmt.Sprintf("/metrics/%s", tc.routeVariable)
+        req, err := http.NewRequest("GET", path, nil)
+        if err != nil {
+            t.Fatal(err)
+        }
+
+        rr := httptest.NewRecorder()
+	
+	// Need to create a router that we can pass the request through so that the vars will be added to the context
+	router := mux.NewRouter()
+        router.HandleFunc("/metrics/{type}", MetricsHandler)
+        router.ServeHTTP(rr, req)
+
+        // In this case, our MetricsHandler returns a non-200 response
+        // for a route variable it doesn't know about.
+        if rr.Code == http.StatusOK && !tc.shouldPass {
+            t.Errorf("handler should have failed on routeVariable %s: got %v want %v",
+                tc.routeVariable, rr.Code, http.StatusOK)
+        }
+    }
+}
+```
+
+## Full Example
+
+Here's a complete, runnable example of a small `mux` based server:
+
+```go
+package main
+
+import (
+    "net/http"
+    "log"
+    "github.com/gorilla/mux"
+)
+
+func YourHandler(w http.ResponseWriter, r *http.Request) {
+    w.Write([]byte("Gorilla!\n"))
+}
+
+func main() {
+    r := mux.NewRouter()
+    // Routes consist of a path and a handler function.
+    r.HandleFunc("/", YourHandler)
+
+    // Bind to a port and pass our router in
+    log.Fatal(http.ListenAndServe(":8000", r))
+}
+```

+Package mux implements a request router and dispatcher.
+
+The name mux stands for "HTTP request multiplexer". Like the standard
+http.ServeMux, mux.Router matches incoming requests against a list of
+registered routes and calls a handler for the route that matches the URL
+or other conditions. The main features are:
+
+	* Requests can be matched based on URL host, path, path prefix, schemes,
+	  header and query values, HTTP methods or using custom matchers.
+	* URL hosts, paths and query values can have variables with an optional
+	  regular expression.
+	* Registered URLs can be built, or "reversed", which helps maintaining
+	  references to resources.
+	* Routes can be used as subrouters: nested routes are only tested if the
+	  parent route matches. This is useful to define groups of routes that
+	  share common conditions like a host, a path prefix or other repeated
+	  attributes. As a bonus, this optimizes request matching.
+	* It implements the http.Handler interface so it is compatible with the
+	  standard http.ServeMux.
+
+Let's start registering a couple of URL paths and handlers:
+
+	func main() {
+		r := mux.NewRouter()
+		r.HandleFunc("/", HomeHandler)
+		r.HandleFunc("/products", ProductsHandler)
+		r.HandleFunc("/articles", ArticlesHandler)
+		http.Handle("/", r)
+	}
+
+Here we register three routes mapping URL paths to handlers. This is
+equivalent to how http.HandleFunc() works: if an incoming request URL matches
+one of the paths, the corresponding handler is called passing
+(http.ResponseWriter, *http.Request) as parameters.
+
+Paths can have variables. They are defined using the format {name} or
+{name:pattern}. If a regular expression pattern is not defined, the matched
+variable will be anything until the next slash. For example:
+
+	r := mux.NewRouter()
+	r.HandleFunc("/products/{key}", ProductHandler)
+	r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
+	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+
+Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
+
+	r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
+
+The names are used to create a map of route variables which can be retrieved
+calling mux.Vars():
+
+	vars := mux.Vars(request)
+	category := vars["category"]
+
+Note that if any capturing groups are present, mux will panic() during parsing. To prevent
+this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
+"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
+when capturing groups were present.
+
+And this is all you need to know about the basic usage. More advanced options
+are explained below.
+
+Routes can also be restricted to a domain or subdomain. Just define a host
+pattern to be matched. They can also have variables:
+
+	r := mux.NewRouter()
+	// Only matches if domain is "www.example.com".
+	r.Host("www.example.com")
+	// Matches a dynamic subdomain.
+	r.Host("{subdomain:[a-z]+}.domain.com")
+
+There are several other matchers that can be added. To match path prefixes:
+
+	r.PathPrefix("/products/")
+
+...or HTTP methods:
+
+	r.Methods("GET", "POST")
+
+...or URL schemes:
+
+	r.Schemes("https")
+
+...or header values:
+
+	r.Headers("X-Requested-With", "XMLHttpRequest")
+
+...or query values:
+
+	r.Queries("key", "value")
+
+...or to use a custom matcher function:
+
+	r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
+		return r.ProtoMajor == 0
+	})
+
+...and finally, it is possible to combine several matchers in a single route:
+
+	r.HandleFunc("/products", ProductsHandler).
+	  Host("www.example.com").
+	  Methods("GET").
+	  Schemes("http")
+
+Setting the same matching conditions again and again can be boring, so we have
+a way to group several routes that share the same requirements.
+We call it "subrouting".
+
+For example, let's say we have several URLs that should only match when the
+host is "www.example.com". Create a route for that host and get a "subrouter"
+from it:
+
+	r := mux.NewRouter()
+	s := r.Host("www.example.com").Subrouter()
+
+Then register routes in the subrouter:
+
+	s.HandleFunc("/products/", ProductsHandler)
+	s.HandleFunc("/products/{key}", ProductHandler)
+	s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
+
+The three URL paths we registered above will only be tested if the domain is
+"www.example.com", because the subrouter is tested first. This is not
+only convenient, but also optimizes request matching. You can create
+subrouters combining any attribute matchers accepted by a route.
+
+Subrouters can be used to create domain or path "namespaces": you define
+subrouters in a central place and then parts of the app can register its
+paths relatively to a given subrouter.
+
+There's one more thing about subroutes. When a subrouter has a path prefix,
+the inner routes use it as base for their paths:
+
+	r := mux.NewRouter()
+	s := r.PathPrefix("/products").Subrouter()
+	// "/products/"
+	s.HandleFunc("/", ProductsHandler)
+	// "/products/{key}/"
+	s.HandleFunc("/{key}/", ProductHandler)
+	// "/products/{key}/details"
+	s.HandleFunc("/{key}/details", ProductDetailsHandler)
+
+Note that the path provided to PathPrefix() represents a "wildcard": calling
+PathPrefix("/static/").Handler(...) means that the handler will be passed any
+request that matches "/static/*". This makes it easy to serve static files with mux:
+
+	func main() {
+		var dir string
+
+		flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
+		flag.Parse()
+		r := mux.NewRouter()
+
+		// This will serve files under http://localhost:8000/static/<filename>
+		r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
+
+		srv := &http.Server{
+			Handler:      r,
+			Addr:         "127.0.0.1:8000",
+			// Good practice: enforce timeouts for servers you create!
+			WriteTimeout: 15 * time.Second,
+			ReadTimeout:  15 * time.Second,
+		}
+
+		log.Fatal(srv.ListenAndServe())
+	}
+
+Now let's see how to build registered URLs.
+
+Routes can be named. All routes that define a name can have their URLs built,
+or "reversed". We define a name calling Name() on a route. For example:
+
+	r := mux.NewRouter()
+	r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
+	  Name("article")
+
+To build a URL, get the route and call the URL() method, passing a sequence of
+key/value pairs for the route variables. For the previous route, we would do:
+
+	url, err := r.Get("article").URL("category", "technology", "id", "42")
+
+...and the result will be a url.URL with the following path:
+
+	"/articles/technology/42"
+
+This also works for host and query value variables:
+
+	r := mux.NewRouter()
+	r.Host("{subdomain}.domain.com").
+	  Path("/articles/{category}/{id:[0-9]+}").
+	  Queries("filter", "{filter}").
+	  HandlerFunc(ArticleHandler).
+	  Name("article")
+
+	// url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
+	url, err := r.Get("article").URL("subdomain", "news",
+	                                 "category", "technology",
+	                                 "id", "42",
+	                                 "filter", "gorilla")
+
+All variables defined in the route are required, and their values must
+conform to the corresponding patterns. These requirements guarantee that a
+generated URL will always match a registered route -- the only exception is
+for explicitly defined "build-only" routes which never match.
+
+Regex support also exists for matching Headers within a route. For example, we could do:
+
+	r.HeadersRegexp("Content-Type", "application/(text|json)")
+
+...and the route will match both requests with a Content-Type of `application/json` as well as
+`application/text`
+
+There's also a way to build only the URL host or path for a route:
+use the methods URLHost() or URLPath() instead. For the previous route,
+we would do:
+
+	// "http://news.domain.com/"
+	host, err := r.Get("article").URLHost("subdomain", "news")
+
+	// "/articles/technology/42"
+	path, err := r.Get("article").URLPath("category", "technology", "id", "42")
+
+And if you use subrouters, host and path defined separately can be built
+as well:
+
+	r := mux.NewRouter()
+	s := r.Host("{subdomain}.domain.com").Subrouter()
+	s.Path("/articles/{category}/{id:[0-9]+}").
+	  HandlerFunc(ArticleHandler).
+	  Name("article")
+
+	// "http://news.domain.com/articles/technology/42"
+	url, err := r.Get("article").URL("subdomain", "news",
+	                                 "category", "technology",
+	                                 "id", "42")
+
+Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
+
+	type MiddlewareFunc func(http.Handler) http.Handler
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+	func simpleMw(next http.Handler) http.Handler {
+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+			// Do stuff here
+			log.Println(r.RequestURI)
+			// Call the next handler, which can be another middleware in the chain, or the final handler.
+			next.ServeHTTP(w, r)
+		})
+	}
+
+Middlewares can be added to a router using `Router.Use()`:
+
+	r := mux.NewRouter()
+	r.HandleFunc("/", handler)
+	r.Use(simpleMw)
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+	// Define our struct
+	type authenticationMiddleware struct {
+		tokenUsers map[string]string
+	}
+
+	// Initialize it somewhere
+	func (amw *authenticationMiddleware) Populate() {
+		amw.tokenUsers["00000000"] = "user0"
+		amw.tokenUsers["aaaaaaaa"] = "userA"
+		amw.tokenUsers["05f717e5"] = "randomUser"
+		amw.tokenUsers["deadbeef"] = "user0"
+	}
+
+	// Middleware function, which will be called for each request
+	func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+			token := r.Header.Get("X-Session-Token")
+
+			if user, found := amw.tokenUsers[token]; found {
+				// We found the token in our map
+				log.Printf("Authenticated user %s\n", user)
+				next.ServeHTTP(w, r)
+			} else {
+				http.Error(w, "Forbidden", http.StatusForbidden)
+			}
+		})
+	}
+
+	r := mux.NewRouter()
+	r.HandleFunc("/", handler)
+
+	amw := authenticationMiddleware{tokenUsers: make(map[string]string)}
+	amw.Populate()
+
+	r.Use(amw.Middleware)
+
+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to.

-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.

-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and

-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS

-# gomatrix
-[![GoDoc](https://godoc.org/github.com/matrix-org/gomatrix?status.svg)](https://godoc.org/github.com/matrix-org/gomatrix)
-
-A Golang Matrix client.
-
-**THIS IS UNDER ACTIVE DEVELOPMENT: BREAKING CHANGES ARE FREQUENT.**
-
-# Contributing
-
-All contributions are greatly appreciated!
-
-## How to report issues
-
-Please check the current open issues for similar reports
-in order to avoid duplicates.
-
-Some general guidelines:
-
--   Include a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example) when possible.
--   Describe the expected behaviour and what actually happened
-    including a full trace-back in case of exceptions.
--   Make sure to list details about your environment
-
-## Setting up your environment
-
-If you intend to contribute to gomatrix you'll first need Go installed on your machine (version 1.12+ is required). Also, make sure to have golangci-lint properly set up since we use it for pre-commit hooks (for instructions on how to install it, check the [official docs](https://golangci-lint.run/usage/install/#local-installation)).
-
--   Fork gomatrix to your GitHub account by clicking the [Fork](https://github.com/matrix-org/gomatrix/fork) button.
--   [Clone](https://help.github.com/en/articles/fork-a-repo#step-2-create-a-local-clone-of-your-fork) the main repository (not your fork) to your local machine.
-
-        
-        $ git clone https://github.com/matrix-org/gomatrix
-        $ cd gomatrix
-        
-
--   Add your fork as a remote to push your contributions.Replace
-    ``{username}`` with your username.
-
-        git remote add fork https://github.com/{username}/gomatrix
-
--   Create a new branch to identify what feature you are working on.
-
-        $ git fetch origin
-        $ git checkout -b your-branch-name origin/master
-        
-
--   Make your changes, including tests that cover any code changes you make, and run them as described below.
-
--   Execute pre-commit hooks by running 
-
-        <gomatrix dir>/hooks/pre-commit
-
--   Push your changes to your fork and [create a pull request](https://help.github.com/en/articles/creating-a-pull-request) describing your changes.
-
-        $ git push --set-upstream fork your-branch-name
-
--   Finally, create a [pull request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests)
-
-## How to run tests
-
-You can run the test suite and example code with `$ go test -v`
-
-# Running Coverage
-
-To run coverage, first generate the coverage report using `go test`
-
-    go test -v -cover -coverprofile=coverage.out
-
-You can now show the generated report as a html page with `go tool`
-
-    go tool cover -html=coverage.out

+# Zero Allocation JSON Logger
+
+[![godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/rs/zerolog) [![license](http://img.shields.io/badge/license-MIT-red.svg?style=flat)](https://raw.githubusercontent.com/rs/zerolog/master/LICENSE) [![Build Status](https://travis-ci.org/rs/zerolog.svg?branch=master)](https://travis-ci.org/rs/zerolog) [![Coverage](http://gocover.io/_badge/github.com/rs/zerolog)](http://gocover.io/github.com/rs/zerolog)
+
+The zerolog package provides a fast and simple logger dedicated to JSON output.
+
+Zerolog's API is designed to provide both a great developer experience and stunning [performance](#benchmarks). Its unique chaining API allows zerolog to write JSON (or CBOR) log events by avoiding allocations and reflection.
+
+Uber's [zap](https://godoc.org/go.uber.org/zap) library pioneered this approach. Zerolog is taking this concept to the next level with a simpler to use API and even better performance.
+
+To keep the code base and the API simple, zerolog focuses on efficient structured logging only. Pretty logging on the console is made possible using the provided (but inefficient) [`zerolog.ConsoleWriter`](#pretty-logging).
+
+![Pretty Logging Image](pretty.png)

+
+## Installation
+
+```bash
+go get -u github.com/rs/zerolog/log
+```
+
+## Getting Started
+
+### Simple Logging Example
+
+For simple logging, import the global logger package **github.com/rs/zerolog/log**
+
+```go
+package main
+
+import (
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    // UNIX Time is faster and smaller than most timestamps
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+    log.Print("hello world")
+}
+
+// Output: {"time":1516134303,"level":"debug","message":"hello world"}
+```
+> Note: By default log writes to `os.Stderr`
+> Note: The default log level for `log.Print` is *debug*
+
+### Contextual Logging
+
+**zerolog** allows data to be added to log messages in the form of key:value pairs. The data added to the message adds "context" about the log event that can be critical for debugging as well as myriad other purposes. An example of this is below:
+
+```go
+package main
+
+import (
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+    log.Debug().
+        Str("Scale", "833 cents").
+        Float64("Interval", 833.09).
+        Msg("Fibonacci is everywhere")
+    
+    log.Debug().
+        Str("Name", "Tom").
+        Send()
+}
+
+// Output: {"level":"debug","Scale":"833 cents","Interval":833.09,"time":1562212768,"message":"Fibonacci is everywhere"}
+// Output: {"level":"debug","Name":"Tom","time":1562212768}
+```
+
+> You'll note in the above example that when adding contextual fields, the fields are strongly typed. You can find the full list of supported fields [here](#standard-types)
+
+### Leveled Logging
+
+#### Simple Leveled Logging Example
+
+```go
+package main
+
+import (
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+    log.Info().Msg("hello world")
+}
+
+// Output: {"time":1516134303,"level":"info","message":"hello world"}
+```
+
+> It is very important to note that when using the **zerolog** chaining API, as shown above (`log.Info().Msg("hello world"`), the chain must have either the `Msg` or `Msgf` method call. If you forget to add either of these, the log will not occur and there is no compile time error to alert you of this.
+
+**zerolog** allows for logging at the following levels (from highest to lowest):
+
+* panic (`zerolog.PanicLevel`, 5)
+* fatal (`zerolog.FatalLevel`, 4)
+* error (`zerolog.ErrorLevel`, 3)
+* warn (`zerolog.WarnLevel`, 2)
+* info (`zerolog.InfoLevel`, 1)
+* debug (`zerolog.DebugLevel`, 0)
+* trace (`zerolog.TraceLevel`, -1)
+
+You can set the Global logging level to any of these options using the `SetGlobalLevel` function in the zerolog package, passing in one of the given constants above, e.g. `zerolog.InfoLevel` would be the "info" level.  Whichever level is chosen, all logs with a level greater than or equal to that level will be written. To turn off logging entirely, pass the `zerolog.Disabled` constant.
+
+#### Setting Global Log Level
+
+This example uses command-line flags to demonstrate various outputs depending on the chosen log level.
+
+```go
+package main
+
+import (
+    "flag"
+
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+    debug := flag.Bool("debug", false, "sets log level to debug")
+
+    flag.Parse()
+
+    // Default level for this example is info, unless debug flag is present
+    zerolog.SetGlobalLevel(zerolog.InfoLevel)
+    if *debug {
+        zerolog.SetGlobalLevel(zerolog.DebugLevel)
+    }
+
+    log.Debug().Msg("This message appears only when log level set to Debug")
+    log.Info().Msg("This message appears when log level set to Debug or Info")
+
+    if e := log.Debug(); e.Enabled() {
+        // Compute log output only if enabled.
+        value := "bar"
+        e.Str("foo", value).Msg("some debug message")
+    }
+}
+```
+
+Info Output (no flag)
+
+```bash
+$ ./logLevelExample
+{"time":1516387492,"level":"info","message":"This message appears when log level set to Debug or Info"}
+```
+
+Debug Output (debug flag set)
+
+```bash
+$ ./logLevelExample -debug
+{"time":1516387573,"level":"debug","message":"This message appears only when log level set to Debug"}
+{"time":1516387573,"level":"info","message":"This message appears when log level set to Debug or Info"}
+{"time":1516387573,"level":"debug","foo":"bar","message":"some debug message"}
+```
+
+#### Logging without Level or Message
+
+You may choose to log without a specific level by using the `Log` method. You may also write without a message by setting an empty string in the `msg string` parameter of the `Msg` method. Both are demonstrated in the example below.
+
+```go
+package main
+
+import (
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+    log.Log().
+        Str("foo", "bar").
+        Msg("")
+}
+
+// Output: {"time":1494567715,"foo":"bar"}
+```
+
+### Error Logging
+
+You can log errors using the `Err` method
+
+```go
+package main
+
+import (
+	"errors"
+
+	"github.com/rs/zerolog"
+	"github.com/rs/zerolog/log"
+)
+
+func main() {
+	zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+	err := errors.New("seems we have an error here")
+	log.Error().Err(err).Msg("")
+}
+
+// Output: {"level":"error","error":"seems we have an error here","time":1609085256}
+```
+
+> The default field name for errors is `error`, you can change this by setting `zerolog.ErrorFieldName` to meet your needs.
+
+#### Error Logging with Stacktrace
+
+Using `github.com/pkg/errors`, you can add a formatted stacktrace to your errors. 
+
+```go
+package main
+
+import (
+	"github.com/pkg/errors"
+	"github.com/rs/zerolog/pkgerrors"
+
+	"github.com/rs/zerolog"
+	"github.com/rs/zerolog/log"
+)
+
+func main() {
+	zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+	zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack
+
+	err := outer()
+	log.Error().Stack().Err(err).Msg("")
+}
+
+func inner() error {
+	return errors.New("seems we have an error here")
+}
+
+func middle() error {
+	err := inner()
+	if err != nil {
+		return err
+	}
+	return nil
+}
+
+func outer() error {
+	err := middle()
+	if err != nil {
+		return err
+	}
+	return nil
+}
+
+// Output: {"level":"error","stack":[{"func":"inner","line":"20","source":"errors.go"},{"func":"middle","line":"24","source":"errors.go"},{"func":"outer","line":"32","source":"errors.go"},{"func":"main","line":"15","source":"errors.go"},{"func":"main","line":"204","source":"proc.go"},{"func":"goexit","line":"1374","source":"asm_amd64.s"}],"error":"seems we have an error here","time":1609086683}
+```
+
+> zerolog.ErrorStackMarshaler must be set in order for the stack to output anything.
+
+#### Logging Fatal Messages
+
+```go
+package main
+
+import (
+    "errors"
+
+    "github.com/rs/zerolog"
+    "github.com/rs/zerolog/log"
+)
+
+func main() {
+    err := errors.New("A repo man spends his life getting into tense situations")
+    service := "myservice"
+
+    zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
+
+    log.Fatal().
+        Err(err).
+        Str("service", service).
+        Msgf("Cannot start %s", service)
+}
+
+// Output: {"time":1516133263,"level":"fatal","error":"A repo man spends his life getting into tense situations","service":"myservice","message":"Cannot start myservice"}
+//         exit status 1
+```
+
+> NOTE: Using `Msgf` generates one allocation even when the logger is disabled.
+
+
+### Create logger instance to manage different outputs
+
+```go
+logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
+
+logger.Info().Str("foo", "bar").Msg("hello world")
+
+// Output: {"level":"info","time":1494567715,"message":"hello world","foo":"bar"}
+```
+
+### Sub-loggers let you chain loggers with additional context
+
+```go
+sublogger := log.With().
+                 Str("component", "foo").
+                 Logger()
+sublogger.Info().Msg("hello world")
+
+// Output: {"level":"info","time":1494567715,"message":"hello world","component":"foo"}
+```
+
+### Pretty logging
+
+To log a human-friendly, colorized output, use `zerolog.ConsoleWriter`:
+
+```go
+log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
+
+log.Info().Str("foo", "bar").Msg("Hello world")
+
+// Output: 3:04PM INF Hello World foo=bar
+```
+
+To customize the configuration and formatting:
+
+```go
+output := zerolog.ConsoleWriter{Out: os.Stdout, TimeFormat: time.RFC3339}
+output.FormatLevel = func(i interface{}) string {
+    return strings.ToUpper(fmt.Sprintf("| %-6s|", i))
+}
+output.FormatMessage = func(i interface{}) string {
+    return fmt.Sprintf("***%s****", i)
+}
+output.FormatFieldName = func(i interface{}) string {
+    return fmt.Sprintf("%s:", i)
+}
+output.FormatFieldValue = func(i interface{}) string {
+    return strings.ToUpper(fmt.Sprintf("%s", i))
+}
+
+log := zerolog.New(output).With().Timestamp().Logger()
+
+log.Info().Str("foo", "bar").Msg("Hello World")
+
+// Output: 2006-01-02T15:04:05Z07:00 | INFO  | ***Hello World**** foo:BAR
+```
+
+### Sub dictionary
+
+```go
+log.Info().
+    Str("foo", "bar").
+    Dict("dict", zerolog.Dict().
+        Str("bar", "baz").
+        Int("n", 1),
+    ).Msg("hello world")
+
+// Output: {"level":"info","time":1494567715,"foo":"bar","dict":{"bar":"baz","n":1},"message":"hello world"}
+```
+
+### Customize automatic field names
+
+```go
+zerolog.TimestampFieldName = "t"
+zerolog.LevelFieldName = "l"
+zerolog.MessageFieldName = "m"
+
+log.Info().Msg("hello world")
+
+// Output: {"l":"info","t":1494567715,"m":"hello world"}
+```
+
+### Add contextual fields to the global logger
+
+```go
+log.Logger = log.With().Str("foo", "bar").Logger()
+```
+
+### Add file and line number to log
+
+Equivalent of `Llongfile`:
+
+```go
+log.Logger = log.With().Caller().Logger()
+log.Info().Msg("hello world")
+
+// Output: {"level": "info", "message": "hello world", "caller": "/go/src/your_project/some_file:21"}
+```
+
+Equivalent of `Lshortfile`:
+
+```go
+zerolog.CallerMarshalFunc = func(pc uintptr, file string, line int) string {
+    short := file
+    for i := len(file) - 1; i > 0; i-- {
+        if file[i] == '/' {
+            short = file[i+1:]
+            break
+        }
+    }
+    file = short
+    return file + ":" + strconv.Itoa(line)
+}
+log.Logger = log.With().Caller().Logger()
+log.Info().Msg("hello world")
+
+// Output: {"level": "info", "message": "hello world", "caller": "some_file:21"}
+```
+
+### Thread-safe, lock-free, non-blocking writer
+
+If your writer might be slow or not thread-safe and you need your log producers to never get slowed down by a slow writer, you can use a `diode.Writer` as follows:
+
+```go
+wr := diode.NewWriter(os.Stdout, 1000, 10*time.Millisecond, func(missed int) {
+		fmt.Printf("Logger Dropped %d messages", missed)
+	})
+log := zerolog.New(wr)
+log.Print("test")
+```
+
+You will need to install `code.cloudfoundry.org/go-diodes` to use this feature.
+
+### Log Sampling
+
+```go
+sampled := log.Sample(&zerolog.BasicSampler{N: 10})
+sampled.Info().Msg("will be logged every 10 messages")
+
+// Output: {"time":1494567715,"level":"info","message":"will be logged every 10 messages"}
+```
+
+More advanced sampling:
+
+```go
+// Will let 5 debug messages per period of 1 second.
+// Over 5 debug message, 1 every 100 debug messages are logged.
+// Other levels are not sampled.
+sampled := log.Sample(zerolog.LevelSampler{
+    DebugSampler: &zerolog.BurstSampler{
+        Burst: 5,
+        Period: 1*time.Second,
+        NextSampler: &zerolog.BasicSampler{N: 100},
+    },
+})
+sampled.Debug().Msg("hello world")
+
+// Output: {"time":1494567715,"level":"debug","message":"hello world"}
+```
+
+### Hooks
+
+```go
+type SeverityHook struct{}
+
+func (h SeverityHook) Run(e *zerolog.Event, level zerolog.Level, msg string) {
+    if level != zerolog.NoLevel {
+        e.Str("severity", level.String())
+    }
+}
+
+hooked := log.Hook(SeverityHook{})
+hooked.Warn().Msg("")
+
+// Output: {"level":"warn","severity":"warn"}
+```
+
+### Pass a sub-logger by context
+
+```go
+ctx := log.With().Str("component", "module").Logger().WithContext(ctx)
+
+log.Ctx(ctx).Info().Msg("hello world")
+
+// Output: {"component":"module","level":"info","message":"hello world"}
+```
+
+### Set as standard logger output
+
+```go
+log := zerolog.New(os.Stdout).With().
+    Str("foo", "bar").
+    Logger()
+
+stdlog.SetFlags(0)
+stdlog.SetOutput(log)
+
+stdlog.Print("hello world")
+
+// Output: {"foo":"bar","message":"hello world"}
+```
+
+### Integration with `net/http`
+
+The `github.com/rs/zerolog/hlog` package provides some helpers to integrate zerolog with `http.Handler`.
+
+In this example we use [alice](https://github.com/justinas/alice) to install logger for better readability.
+
+```go
+log := zerolog.New(os.Stdout).With().
+    Timestamp().
+    Str("role", "my-service").
+    Str("host", host).
+    Logger()
+
+c := alice.New()
+
+// Install the logger handler with default output on the console
+c = c.Append(hlog.NewHandler(log))
+
+// Install some provided extra handler to set some request's context fields.
+// Thanks to that handler, all our logs will come with some prepopulated fields.
+c = c.Append(hlog.AccessHandler(func(r *http.Request, status, size int, duration time.Duration) {
+    hlog.FromRequest(r).Info().
+        Str("method", r.Method).
+        Stringer("url", r.URL).
+        Int("status", status).
+        Int("size", size).
+        Dur("duration", duration).
+        Msg("")
+}))
+c = c.Append(hlog.RemoteAddrHandler("ip"))
+c = c.Append(hlog.UserAgentHandler("user_agent"))
+c = c.Append(hlog.RefererHandler("referer"))
+c = c.Append(hlog.RequestIDHandler("req_id", "Request-Id"))
+
+// Here is your final handler
+h := c.Then(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+    // Get the logger from the request's context. You can safely assume it
+    // will be always there: if the handler is removed, hlog.FromRequest
+    // will return a no-op logger.
+    hlog.FromRequest(r).Info().
+        Str("user", "current user").
+        Str("status", "ok").
+        Msg("Something happened")
+
+    // Output: {"level":"info","time":"2001-02-03T04:05:06Z","role":"my-service","host":"local-hostname","req_id":"b4g0l5t6tfid6dtrapu0","user":"current user","status":"ok","message":"Something happened"}
+}))
+http.Handle("/", h)
+
+if err := http.ListenAndServe(":8080", nil); err != nil {
+    log.Fatal().Err(err).Msg("Startup failed")
+}
+```
+
+## Multiple Log Output
+`zerolog.MultiLevelWriter` may be used to send the log message to multiple outputs. 
+In this example, we send the log message to both `os.Stdout` and the in-built ConsoleWriter.
+```go
+func main() {
+	consoleWriter := zerolog.ConsoleWriter{Out: os.Stdout}
+
+	multi := zerolog.MultiLevelWriter(consoleWriter, os.Stdout)
+
+	logger := zerolog.New(multi).With().Timestamp().Logger()
+
+	logger.Info().Msg("Hello World!")
+}
+
+// Output (Line 1: Console; Line 2: Stdout)
+// 12:36PM INF Hello World!
+// {"level":"info","time":"2019-11-07T12:36:38+03:00","message":"Hello World!"}
+```
+
+## Global Settings
+
+Some settings can be changed and will be applied to all loggers:
+
+* `log.Logger`: You can set this value to customize the global logger (the one used by package level methods).
+* `zerolog.SetGlobalLevel`: Can raise the minimum level of all loggers. Call this with `zerolog.Disabled` to disable logging altogether (quiet mode).
+* `zerolog.DisableSampling`: If argument is `true`, all sampled loggers will stop sampling and issue 100% of their log events.
+* `zerolog.TimestampFieldName`: Can be set to customize `Timestamp` field name.
+* `zerolog.LevelFieldName`: Can be set to customize level field name.
+* `zerolog.MessageFieldName`: Can be set to customize message field name.
+* `zerolog.ErrorFieldName`: Can be set to customize `Err` field name.
+* `zerolog.TimeFieldFormat`: Can be set to customize `Time` field value formatting. If set with `zerolog.TimeFormatUnix`, `zerolog.TimeFormatUnixMs` or `zerolog.TimeFormatUnixMicro`, times are formated as UNIX timestamp.
+* `zerolog.DurationFieldUnit`: Can be set to customize the unit for time.Duration type fields added by `Dur` (default: `time.Millisecond`).
+* `zerolog.DurationFieldInteger`: If set to `true`, `Dur` fields are formatted as integers instead of floats (default: `false`). 
+* `zerolog.ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking.
+
+## Field Types
+
+### Standard Types
+
+* `Str`
+* `Bool`
+* `Int`, `Int8`, `Int16`, `Int32`, `Int64`
+* `Uint`, `Uint8`, `Uint16`, `Uint32`, `Uint64`
+* `Float32`, `Float64`
+
+### Advanced Fields
+
+* `Err`: Takes an `error` and renders it as a string using the `zerolog.ErrorFieldName` field name.
+* `Func`: Run a `func` only if the level is enabled.
+* `Timestamp`: Inserts a timestamp field with `zerolog.TimestampFieldName` field name, formatted using `zerolog.TimeFieldFormat`.
+* `Time`: Adds a field with time formatted with `zerolog.TimeFieldFormat`.
+* `Dur`: Adds a field with `time.Duration`.
+* `Dict`: Adds a sub-key/value as a field of the event.
+* `RawJSON`: Adds a field with an already encoded JSON (`[]byte`)
+* `Hex`: Adds a field with value formatted as a hexadecimal string (`[]byte`)
+* `Interface`: Uses reflection to marshal the type.
+
+Most fields are also available in the slice format (`Strs` for `[]string`, `Errs` for `[]error` etc.)
+
+## Binary Encoding
+
+In addition to the default JSON encoding, `zerolog` can produce binary logs using [CBOR](https://cbor.io) encoding. The choice of encoding can be decided at compile time using the build tag `binary_log` as follows:
+
+```bash
+go build -tags binary_log .
+```
+
+To Decode binary encoded log files you can use any CBOR decoder. One has been tested to work
+with zerolog library is [CSD](https://github.com/toravir/csd/).

+
+Using Uber's zap comparison benchmark:
+

+| lion | 771 ns/op | 1224 B/op | 10 allocs/op |
+| logrus | 1244 ns/op | 1505 B/op | 27 allocs/op |
+| apex/log | 2751 ns/op | 584 B/op | 11 allocs/op |
+| log15 | 5181 ns/op | 1592 B/op | 26 allocs/op |
+
+## Caveats
+
+Note that zerolog does no de-duplication of fields. Using the same key multiple times creates multiple keys in final JSON:
+
+```go
+logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
+logger.Info().
+       Timestamp().
+       Msg("dup")
+// Output: {"level":"info","time":1494567715,"time":1494567715,"message":"dup"}
+```
+
+In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt.

+1. CPU usage to write a log msg 
+2. Size (in bytes) of log messages.
+
+
+CPU Usage savings are below:

+```
+
+Log message size savings is greatly dependent on the number and type of fields in the log message.
+Assuming this log message (with an Integer, timestamp and string, in addition to level).
+
+`{"level":"error","Fault":41650,"time":"2018-04-01T15:18:19-07:00","message":"Some Message"}`
+
+Two measurements were done for the log file sizes - one without any compression, second
+using [compress/zlib](https://golang.org/pkg/compress/zlib/). 
+
+Results for 10,000 log messages:
+
+| Log Format |  Plain File Size (in KB) | Compressed File Size (in KB) |
+| :--- | :---: | :---: |
+| JSON | 920 | 28 |
+| CBOR | 550 | 28 |
+
+The example used to calculate the above data is available in [Examples](examples).

+
+GJSON is a Go package that provides a [fast](#performance) and [simple](#get-a-value) way to get values from a json document.
+It has features such as [one line retrieval](#get-a-value), [dot notation paths](#path-syntax), [iteration](#iterate-through-an-object-or-array), and [parsing json lines](#json-lines).
+
+Also check out [SJSON](https://github.com/tidwall/sjson) for modifying json, and the [JJ](https://github.com/tidwall/jj) command line tool.
+
+This README is a quick overview of how to use GJSON, for more information check out [GJSON Syntax](SYNTAX.md).
+
+GJSON is also available for [Python](https://github.com/volans-/gjson-py) and [Rust](https://github.com/tidwall/gjson.rs)
+
+Getting Started
+===============
+
+## Installing
+
+To start using GJSON, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/gjson
+```
+
+This will retrieve the library.
+
+## Get a value
+Get searches json for the specified path. A path is in dot syntax, such as "name.last" or "age". When the value is found it's returned immediately. 
+
+```go
+package main
+
+import "github.com/tidwall/gjson"
+
+const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
+
+func main() {
+	value := gjson.Get(json, "name.last")
+	println(value.String())
+}
+```
+
+This will print:
+
+```
+Prichard
+```
+*There's also the [GetMany](#get-multiple-values-at-once) function to get multiple values at once, and [GetBytes](#working-with-bytes) for working with JSON byte slices.*
+
+## Path Syntax
+
+Below is a quick overview of the path syntax, for more complete information please
+check out [GJSON Syntax](SYNTAX.md).
+
+A path is a series of keys separated by a dot.
+A key may contain special wildcard characters '\*' and '?'.
+To access an array value use the index as the key.
+To get the number of elements in an array or to access a child path, use the '#' character.
+The dot and wildcard characters can be escaped with '\\'.
+
+```json
+{
+  "name": {"first": "Tom", "last": "Anderson"},
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {"first": "Dale", "last": "Murphy", "age": 44, "nets": ["ig", "fb", "tw"]},
+    {"first": "Roger", "last": "Craig", "age": 68, "nets": ["fb", "tw"]},
+    {"first": "Jane", "last": "Murphy", "age": 47, "nets": ["ig", "tw"]}
+  ]
+}
+```
+```
+"name.last"          >> "Anderson"
+"age"                >> 37
+"children"           >> ["Sara","Alex","Jack"]
+"children.#"         >> 3
+"children.1"         >> "Alex"
+"child*.2"           >> "Jack"
+"c?ildren.0"         >> "Sara"
+"fav\.movie"         >> "Deer Hunter"
+"friends.#.first"    >> ["Dale","Roger","Jane"]
+"friends.1.last"     >> "Craig"
+```
+
+You can also query an array for the first match by using `#(...)`, or find all 
+matches with `#(...)#`. Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` 
+comparison operators and the simple pattern matching `%` (like) and `!%` 
+(not like) operators.
+
+```
+friends.#(last=="Murphy").first    >> "Dale"
+friends.#(last=="Murphy")#.first   >> ["Dale","Jane"]
+friends.#(age>45)#.last            >> ["Craig","Murphy"]
+friends.#(first%"D*").last         >> "Murphy"
+friends.#(first!%"D*").last        >> "Craig"
+friends.#(nets.#(=="fb"))#.first   >> ["Dale","Roger"]
+```
+
+*Please note that prior to v1.3.0, queries used the `#[...]` brackets. This was
+changed in v1.3.0 as to avoid confusion with the new
+[multipath](SYNTAX.md#multipaths) syntax. For backwards compatibility, 
+`#[...]` will continue to work until the next major release.*
+
+## Result Type
+
+GJSON supports the json types `string`, `number`, `bool`, and `null`. 
+Arrays and Objects are returned as their raw json types. 
+
+The `Result` type holds one of these:
+
+```
+bool, for JSON booleans
+float64, for JSON numbers
+string, for JSON string literals
+nil, for JSON null
+```
+
+To directly access the value:
+
+```go
+result.Type           // can be String, Number, True, False, Null, or JSON
+result.Str            // holds the string
+result.Num            // holds the float64 number
+result.Raw            // holds the raw json
+result.Index          // index of raw value in original json, zero means index unknown
+result.Indexes        // indexes of all the elements that match on a path containing the '#' query character.
+```
+
+There are a variety of handy functions that work on a result:
+
+```go
+result.Exists() bool
+result.Value() interface{}
+result.Int() int64
+result.Uint() uint64
+result.Float() float64
+result.String() string
+result.Bool() bool
+result.Time() time.Time
+result.Array() []gjson.Result
+result.Map() map[string]gjson.Result
+result.Get(path string) Result
+result.ForEach(iterator func(key, value Result) bool)
+result.Less(token Result, caseSensitive bool) bool
+```
+
+The `result.Value()` function returns an `interface{}` which requires type assertion and is one of the following Go types:
+
+```go
+boolean >> bool
+number  >> float64
+string  >> string
+null    >> nil
+array   >> []interface{}
+object  >> map[string]interface{}
+```
+
+The `result.Array()` function returns back an array of values.
+If the result represents a non-existent value, then an empty array will be returned.
+If the result is not a JSON array, the return value will be an array containing one result.
+
+### 64-bit integers
+
+The `result.Int()` and `result.Uint()` calls are capable of reading all 64 bits, allowing for large JSON integers.
+
+```go
+result.Int() int64    // -9223372036854775808 to 9223372036854775807
+result.Uint() uint64   // 0 to 18446744073709551615
+```
+
+## Modifiers and path chaining 
+
+New in version 1.2 is support for modifier functions and path chaining.
+
+A modifier is a path component that performs custom processing on the 
+json.
+
+Multiple paths can be "chained" together using the pipe character. 
+This is useful for getting results from a modified query.
+
+For example, using the built-in `@reverse` modifier on the above json document,
+we'll get `children` array and reverse the order:
+
+```
+"children|@reverse"           >> ["Jack","Alex","Sara"]
+"children|@reverse|0"         >> "Jack"
+```
+
+There are currently the following built-in modifiers:
+
+- `@reverse`: Reverse an array or the members of an object.
+- `@ugly`: Remove all whitespace from a json document.
+- `@pretty`: Make the json document more human readable.
+- `@this`: Returns the current element. It can be used to retrieve the root element.
+- `@valid`: Ensure the json document is valid.
+- `@flatten`: Flattens an array.
+- `@join`: Joins multiple objects into a single object.
+- `@keys`: Returns an array of keys for an object.
+- `@values`: Returns an array of values for an object.
+- `@tostr`: Converts json to a string. Wraps a json string.
+- `@fromstr`: Converts a string from json. Unwraps a json string.
+- `@group`: Groups arrays of objects. See [e4fc67c](https://github.com/tidwall/gjson/commit/e4fc67c92aeebf2089fabc7872f010e340d105db).
+
+### Modifier arguments
+
+A modifier may accept an optional argument. The argument can be a valid JSON 
+document or just characters.
+
+For example, the `@pretty` modifier takes a json object as its argument. 
+
+```
+@pretty:{"sortKeys":true} 
+```
+
+Which makes the json pretty and orders all of its keys.
+
+```json
+{
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {"age": 44, "first": "Dale", "last": "Murphy"},
+    {"age": 68, "first": "Roger", "last": "Craig"},
+    {"age": 47, "first": "Jane", "last": "Murphy"}
+  ],
+  "name": {"first": "Tom", "last": "Anderson"}
+}
+```
+
+*The full list of `@pretty` options are `sortKeys`, `indent`, `prefix`, and `width`. 
+Please see [Pretty Options](https://github.com/tidwall/pretty#customized-output) for more information.*
+
+### Custom modifiers
+
+You can also add custom modifiers.
+
+For example, here we create a modifier that makes the entire json document upper
+or lower case.
+
+```go
+gjson.AddModifier("case", func(json, arg string) string {
+  if arg == "upper" {
+    return strings.ToUpper(json)
+  }
+  if arg == "lower" {
+    return strings.ToLower(json)
+  }
+  return json
+})
+```
+
+```
+"children|@case:upper"           >> ["SARA","ALEX","JACK"]
+"children|@case:lower|@reverse"  >> ["jack","alex","sara"]
+```
+
+## JSON Lines
+
+There's support for [JSON Lines](http://jsonlines.org/) using the `..` prefix, which treats a multilined document as an array. 
+
+For example:
+
+```
+{"name": "Gilbert", "age": 61}
+{"name": "Alexa", "age": 34}
+{"name": "May", "age": 57}
+{"name": "Deloise", "age": 44}
+```
+
+```
+..#                   >> 4
+..1                   >> {"name": "Alexa", "age": 34}
+..3                   >> {"name": "Deloise", "age": 44}
+..#.name              >> ["Gilbert","Alexa","May","Deloise"]
+..#(name="May").age   >> 57
+```
+
+The `ForEachLines` function will iterate through JSON lines.
+
+```go
+gjson.ForEachLine(json, func(line gjson.Result) bool{
+    println(line.String())
+    return true
+})
+```
+
+## Get nested array values
+
+Suppose you want all the last names from the following json:
+
+```json
+{
+  "programmers": [
+    {
+      "firstName": "Janet", 
+      "lastName": "McLaughlin", 
+    }, {
+      "firstName": "Elliotte", 
+      "lastName": "Hunter", 
+    }, {
+      "firstName": "Jason", 
+      "lastName": "Harold", 
+    }
+  ]
+}
+```
+
+You would use the path "programmers.#.lastName" like such:
+
+```go
+result := gjson.Get(json, "programmers.#.lastName")
+for _, name := range result.Array() {
+	println(name.String())
+}
+```
+
+You can also query an object inside an array:
+
+```go
+name := gjson.Get(json, `programmers.#(lastName="Hunter").firstName`)
+println(name.String())  // prints "Elliotte"
+```
+
+## Iterate through an object or array
+
+The `ForEach` function allows for quickly iterating through an object or array. 
+The key and value are passed to the iterator function for objects.
+Only the value is passed for arrays.
+Returning `false` from an iterator will stop iteration.
+
+```go
+result := gjson.Get(json, "programmers")
+result.ForEach(func(key, value gjson.Result) bool {
+	println(value.String()) 
+	return true // keep iterating
+})
+```
+
+## Simple Parse and Get
+
+There's a `Parse(json)` function that will do a simple parse, and `result.Get(path)` that will search a result.
+
+For example, all of these will return the same result:
+
+```go
+gjson.Parse(json).Get("name").Get("last")
+gjson.Get(json, "name").Get("last")
+gjson.Get(json, "name.last")
+```
+
+## Check for the existence of a value
+
+Sometimes you just want to know if a value exists. 
+
+```go
+value := gjson.Get(json, "name.last")
+if !value.Exists() {
+	println("no last name")
+} else {
+	println(value.String())
+}
+
+// Or as one step
+if gjson.Get(json, "name.last").Exists() {
+	println("has a last name")
+}
+```
+
+## Validate JSON
+
+The `Get*` and `Parse*` functions expects that the json is well-formed. Bad json will not panic, but it may return back unexpected results.
+
+If you are consuming JSON from an unpredictable source then you may want to validate prior to using GJSON.
+
+```go
+if !gjson.Valid(json) {
+	return errors.New("invalid json")
+}
+value := gjson.Get(json, "name.last")
+```
+
+## Unmarshal to a map
+
+To unmarshal to a `map[string]interface{}`:
+
+```go
+m, ok := gjson.Parse(json).Value().(map[string]interface{})
+if !ok {
+	// not a map
+}
+```
+
+## Working with Bytes
+
+If your JSON is contained in a `[]byte` slice, there's the [GetBytes](https://godoc.org/github.com/tidwall/gjson#GetBytes) function. This is preferred over `Get(string(data), path)`.
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+```
+
+If you are using the `gjson.GetBytes(json, path)` function and you want to avoid converting `result.Raw` to a `[]byte`, then you can use this pattern:
+
+```go
+var json []byte = ...
+result := gjson.GetBytes(json, path)
+var raw []byte
+if result.Index > 0 {
+    raw = json[result.Index:result.Index+len(result.Raw)]
+} else {
+    raw = []byte(result.Raw)
+}
+```
+
+This is a best-effort no allocation sub slice of the original json. This method utilizes the `result.Index` field, which is the position of the raw data in the original json. It's possible that the value of `result.Index` equals zero, in which case the `result.Raw` is converted to a `[]byte`.
+
+## Get multiple values at once
+
+The `GetMany` function can be used to get multiple values at the same time.
+
+```go
+results := gjson.GetMany(json, "name.first", "name.last", "age")
+```
+
+The return value is a `[]Result`, which will always contain exactly the same number of items as the input paths.

+# GJSON Path Syntax
+
+A GJSON Path is a text string syntax that describes a search pattern for quickly retreiving values from a JSON payload.
+
+This document is designed to explain the structure of a GJSON Path through examples.
+
+- [Path structure](#path-structure)
+- [Basic](#basic)
+- [Wildcards](#wildcards)
+- [Escape Character](#escape-character)
+- [Arrays](#arrays)
+- [Queries](#queries)
+- [Dot vs Pipe](#dot-vs-pipe)
+- [Modifiers](#modifiers)
+- [Multipaths](#multipaths)
+- [Literals](#literals)
+
+The definitive implemenation is [github.com/tidwall/gjson](https://github.com/tidwall/gjson).  
+Use the [GJSON Playground](https://gjson.dev) to experiment with the syntax online.
+
+## Path structure
+
+A GJSON Path is intended to be easily expressed as a series of components seperated by a `.` character. 
+
+Along with `.` character, there are a few more that have special meaning, including `|`, `#`, `@`, `\`, `*`, `!`, and `?`.
+
+## Example
+
+Given this JSON
+
+```json
+{
+  "name": {"first": "Tom", "last": "Anderson"},
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {"first": "Dale", "last": "Murphy", "age": 44, "nets": ["ig", "fb", "tw"]},
+    {"first": "Roger", "last": "Craig", "age": 68, "nets": ["fb", "tw"]},
+    {"first": "Jane", "last": "Murphy", "age": 47, "nets": ["ig", "tw"]}
+  ]
+}
+```
+
+The following GJSON Paths evaluate to the accompanying values.
+
+### Basic 
+
+In many cases you'll just want to retreive values by object name or array index.
+
+```go
+name.last              "Anderson"
+name.first             "Tom"
+age                    37
+children               ["Sara","Alex","Jack"]
+children.0             "Sara"
+children.1             "Alex"
+friends.1              {"first": "Roger", "last": "Craig", "age": 68}
+friends.1.first        "Roger"
+```
+
+### Wildcards
+
+A key may contain the special wildcard characters `*` and `?`. 
+The `*` will match on any zero+ characters, and `?` matches on any one character.
+
+```go
+child*.2               "Jack"
+c?ildren.0             "Sara"
+```
+
+### Escape character
+
+Special purpose characters, such as `.`, `*`, and `?` can be escaped with `\`. 
+
+```go
+fav\.movie             "Deer Hunter"
+```
+
+You'll also need to make sure that the `\` character is correctly escaped when hardcoding a path in your source code.
+
+```go
+// Go
+val := gjson.Get(json, "fav\\.movie")  // must escape the slash
+val := gjson.Get(json, `fav\.movie`)   // no need to escape the slash 
+```
+
+```rust
+// Rust
+let val = gjson::get(json, "fav\\.movie")     // must escape the slash
+let val = gjson::get(json, r#"fav\.movie"#)   // no need to escape the slash 
+```
+
+
+### Arrays
+
+The `#` character allows for digging into JSON Arrays.
+
+To get the length of an array you'll just use the `#` all by itself.
+
+```go
+friends.#              3
+friends.#.age         [44,68,47]
+```
+
+### Queries
+
+You can also query an array for the first match by  using `#(...)`, or find all matches with `#(...)#`. 
+Queries support the `==`, `!=`, `<`, `<=`, `>`, `>=` comparison operators, 
+and the simple pattern matching `%` (like) and `!%` (not like) operators.
+
+```go
+friends.#(last=="Murphy").first     "Dale"
+friends.#(last=="Murphy")#.first    ["Dale","Jane"]
+friends.#(age>45)#.last             ["Craig","Murphy"]
+friends.#(first%"D*").last          "Murphy"
+friends.#(first!%"D*").last         "Craig"
+```
+
+To query for a non-object value in an array, you can forgo the string to the right of the operator.
+
+```go
+children.#(!%"*a*")                 "Alex"
+children.#(%"*a*")#                 ["Sara","Jack"]
+```
+
+Nested queries are allowed.
+
+```go
+friends.#(nets.#(=="fb"))#.first  >> ["Dale","Roger"]
+```
+
+*Please note that prior to v1.3.0, queries used the `#[...]` brackets. This was
+changed in v1.3.0 as to avoid confusion with the new [multipath](#multipaths) 
+syntax. For backwards compatibility, `#[...]` will continue to work until the
+next major release.*
+
+The `~` (tilde) operator will convert a value to a boolean before comparison.
+
+For example, using the following JSON:
+
+```json
+{
+  "vals": [
+    { "a": 1, "b": true },
+    { "a": 2, "b": true },
+    { "a": 3, "b": false },
+    { "a": 4, "b": "0" },
+    { "a": 5, "b": 0 },
+    { "a": 6, "b": "1" },
+    { "a": 7, "b": 1 },
+    { "a": 8, "b": "true" },
+    { "a": 9, "b": false },
+    { "a": 10, "b": null },
+    { "a": 11 }
+  ]
+}
+```
+
+You can now query for all true(ish) or false(ish) values:
+
+```
+vals.#(b==~true)#.a    >> [1,2,6,7,8]
+vals.#(b==~false)#.a   >> [3,4,5,9,10,11]
+```
+
+The last value which was non-existent is treated as `false`
+
+### Dot vs Pipe
+
+The `.` is standard separator, but it's also possible to use a `|`. 
+In most cases they both end up returning the same results.
+The cases where`|` differs from `.` is when it's used after the `#` for [Arrays](#arrays) and [Queries](#queries). 
+
+Here are some examples
+
+```go
+friends.0.first                     "Dale"
+friends|0.first                     "Dale"
+friends.0|first                     "Dale"
+friends|0|first                     "Dale"
+friends|#                           3
+friends.#                           3
+friends.#(last="Murphy")#           [{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}]
+friends.#(last="Murphy")#.first     ["Dale","Jane"]
+friends.#(last="Murphy")#|first     <non-existent>
+friends.#(last="Murphy")#.0         []
+friends.#(last="Murphy")#|0         {"first": "Dale", "last": "Murphy", "age": 44}
+friends.#(last="Murphy")#.#         []
+friends.#(last="Murphy")#|#         2
+```
+
+Let's break down a few of these.
+
+The path `friends.#(last="Murphy")#` all by itself results in
+
+```json
+[{"first": "Dale", "last": "Murphy", "age": 44},{"first": "Jane", "last": "Murphy", "age": 47}]
+```
+
+The `.first` suffix will process the `first` path on each array element *before* returning the results. Which becomes
+
+```json
+["Dale","Jane"]
+```
+
+But the `|first` suffix actually processes the `first` path *after* the previous result. 
+Since the previous result is an array, not an object, it's not possible to process 
+because `first` does not exist.
+
+Yet, `|0` suffix returns
+
+```json
+{"first": "Dale", "last": "Murphy", "age": 44}
+```
+
+Because `0` is the first index of the previous result.
+
+### Modifiers
+
+A modifier is a path component that performs custom processing on the JSON.
+
+For example, using the built-in `@reverse` modifier on the above JSON payload will reverse the `children` array:
+
+```go
+children.@reverse                   ["Jack","Alex","Sara"]
+children.@reverse.0                 "Jack"
+```
+
+There are currently the following built-in modifiers:
+
+- `@reverse`: Reverse an array or the members of an object.
+- `@ugly`: Remove all whitespace from JSON.
+- `@pretty`: Make the JSON more human readable.
+- `@this`: Returns the current element. It can be used to retrieve the root element.
+- `@valid`: Ensure the json document is valid.
+- `@flatten`: Flattens an array.
+- `@join`: Joins multiple objects into a single object.
+- `@keys`: Returns an array of keys for an object.
+- `@values`: Returns an array of values for an object.
+- `@tostr`: Converts json to a string. Wraps a json string.
+- `@fromstr`: Converts a string from json. Unwraps a json string.
+- `@group`: Groups arrays of objects. See [e4fc67c](https://github.com/tidwall/gjson/commit/e4fc67c92aeebf2089fabc7872f010e340d105db).
+
+#### Modifier arguments
+
+A modifier may accept an optional argument. The argument can be a valid JSON payload or just characters.
+
+For example, the `@pretty` modifier takes a json object as its argument.
+
+```
+@pretty:{"sortKeys":true}
+```
+
+Which makes the json pretty and orders all of its keys.
+
+```json
+{
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {"age": 44, "first": "Dale", "last": "Murphy"},
+    {"age": 68, "first": "Roger", "last": "Craig"},
+    {"age": 47, "first": "Jane", "last": "Murphy"}
+  ],
+  "name": {"first": "Tom", "last": "Anderson"}
+}
+```
+
+*The full list of `@pretty` options are `sortKeys`, `indent`, `prefix`, and `width`. 
+Please see [Pretty Options](https://github.com/tidwall/pretty#customized-output) for more information.*
+
+#### Custom modifiers
+
+You can also add custom modifiers. 
+
+For example, here we create a modifier which makes the entire JSON payload upper or lower case.
+
+```go
+gjson.AddModifier("case", func(json, arg string) string {
+  if arg == "upper" {
+    return strings.ToUpper(json)
+  }
+  if arg == "lower" {
+    return strings.ToLower(json)
+  }
+  return json
+})
+"children.@case:upper"             ["SARA","ALEX","JACK"]
+"children.@case:lower.@reverse"    ["jack","alex","sara"]
+```
+
+*Note: Custom modifiers are not yet available in the Rust version*
+
+### Multipaths
+
+Starting with v1.3.0, GJSON added the ability to join multiple paths together
+to form new documents. Wrapping comma-separated paths between `[...]` or
+`{...}` will result in a new array or object, respectively.
+
+For example, using the given multipath:
+
+```
+{name.first,age,"the_murphys":friends.#(last="Murphy")#.first}
+```
+
+Here we selected the first name, age, and the first name for friends with the 
+last name "Murphy".
+
+You'll notice that an optional key can be provided, in this case 
+"the_murphys", to force assign a key to a value. Otherwise, the name of the 
+actual field will be used, in this case "first". If a name cannot be
+determined, then "_" is used.
+
+This results in
+
+```json
+{"first":"Tom","age":37,"the_murphys":["Dale","Jane"]}
+```
+
+### Literals
+
+Starting with v1.12.0, GJSON added support of json literals, which provides a way for constructing static blocks of json. This is can be particularly useful when constructing a new json document using [multipaths](#multipaths).  
+
+A json literal begins with the '!' declaration character. 
+
+For example, using the given multipath:
+
+```
+{name.first,age,"company":!"Happysoft","employed":!true}
+```
+
+Here we selected the first name and age. Then add two new fields, "company" and "employed".
+
+This results in 
+
+```json
+{"first":"Tom","age":37,"company":"Happysoft","employed":true}
+```
+
+*See issue [#249](https://github.com/tidwall/gjson/issues/249) for additional context on JSON Literals.*

+# Pretty
+
+[![GoDoc](https://img.shields.io/badge/api-reference-blue.svg?style=flat-square)](https://pkg.go.dev/github.com/tidwall/pretty) 
+
+Pretty is a Go package that provides [fast](#performance) methods for formatting JSON for human readability, or to compact JSON for smaller payloads.
+
+Getting Started
+===============
+
+## Installing
+
+To start using Pretty, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/pretty
+```
+
+This will retrieve the library.
+
+## Pretty
+
+Using this example:
+
+```json
+{"name":  {"first":"Tom","last":"Anderson"},  "age":37,
+"children": ["Sara","Alex","Jack"],
+"fav.movie": "Deer Hunter", "friends": [
+    {"first": "Janet", "last": "Murphy", "age": 44}
+  ]}
+```
+
+The following code:
+```go
+result = pretty.Pretty(example)
+```
+
+Will format the json to:
+
+```json
+{
+  "name": {
+    "first": "Tom",
+    "last": "Anderson"
+  },
+  "age": 37,
+  "children": ["Sara", "Alex", "Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+    {
+      "first": "Janet",
+      "last": "Murphy",
+      "age": 44
+    }
+  ]
+}
+```
+
+## Color
+
+Color will colorize the json for outputing to the screen. 
+
+```json
+result = pretty.Color(json, nil)
+```
+
+Will add color to the result for printing to the terminal.
+The second param is used for a customizing the style, and passing nil will use the default `pretty.TerminalStyle`.
+
+## Ugly
+
+The following code:
+```go
+result = pretty.Ugly(example)
+```
+
+Will format the json to:
+
+```json
+{"name":{"first":"Tom","last":"Anderson"},"age":37,"children":["Sara","Alex","Jack"],"fav.movie":"Deer Hunter","friends":[{"first":"Janet","last":"Murphy","age":44}]}```
+```
+
+## Customized output
+
+There's a `PrettyOptions(json, opts)` function which allows for customizing the output with the following options:
+
+```go
+type Options struct {
+	// Width is an max column width for single line arrays
+	// Default is 80
+	Width int
+	// Prefix is a prefix for all lines
+	// Default is an empty string
+	Prefix string
+	// Indent is the nested indentation
+	// Default is two spaces
+	Indent string
+	// SortKeys will sort the keys alphabetically
+	// Default is false
+	SortKeys bool
+}
+```
+## Performance
+
+Benchmarks of Pretty alongside the builtin `encoding/json` Indent/Compact methods.
+```
+BenchmarkPretty-16           1000000    1034 ns/op    720 B/op     2 allocs/op
+BenchmarkPrettySortKeys-16    586797    1983 ns/op   2848 B/op    14 allocs/op
+BenchmarkUgly-16             4652365     254 ns/op    240 B/op     1 allocs/op
+BenchmarkUglyInPlace-16      6481233     183 ns/op      0 B/op     0 allocs/op
+BenchmarkJSONIndent-16        450654    2687 ns/op   1221 B/op     0 allocs/op
+BenchmarkJSONCompact-16       685111    1699 ns/op    442 B/op     0 allocs/op
+```
+
+*These benchmarks were run on a MacBook Pro 2.4 GHz 8-Core Intel Core i9.*

+<p align="center">set a json value quickly</p>
+
+SJSON is a Go package that provides a [very fast](#performance) and simple way to set a value in a json document.
+For quickly retrieving json values check out [GJSON](https://github.com/tidwall/gjson).
+
+For a command line interface check out [JJ](https://github.com/tidwall/jj).
+
+Getting Started
+===============
+
+Installing
+----------
+
+To start using SJSON, install Go and run `go get`:
+
+```sh
+$ go get -u github.com/tidwall/sjson
+```
+
+This will retrieve the library.
+
+Set a value
+-----------
+Set sets the value for the specified path. 
+A path is in dot syntax, such as "name.last" or "age". 
+This function expects that the json is well-formed and validated. 
+Invalid json will not panic, but it may return back unexpected results.
+Invalid paths may return an error.
+
+```go
+package main
+
+import "github.com/tidwall/sjson"
+
+const json = `{"name":{"first":"Janet","last":"Prichard"},"age":47}`
+
+func main() {
+	value, _ := sjson.Set(json, "name.last", "Anderson")
+	println(value)
+}
+```
+
+This will print:
+
+```json
+{"name":{"first":"Janet","last":"Anderson"},"age":47}
+```
+
+Path syntax
+-----------
+
+A path is a series of keys separated by a dot.
+The dot and colon characters can be escaped with ``\``.
+
+```json
+{
+  "name": {"first": "Tom", "last": "Anderson"},
+  "age":37,
+  "children": ["Sara","Alex","Jack"],
+  "fav.movie": "Deer Hunter",
+  "friends": [
+	{"first": "James", "last": "Murphy"},
+	{"first": "Roger", "last": "Craig"}
+  ]
+}
+```
+```
+"name.last"          >> "Anderson"
+"age"                >> 37
+"children.1"         >> "Alex"
+"friends.1.last"     >> "Craig"
+```
+
+The `-1` key can be used to append a value to an existing array:
+
+```
+"children.-1"  >> appends a new value to the end of the children array
+```
+
+Normally number keys are used to modify arrays, but it's possible to force a numeric object key by using the colon character:
+
+```json
+{
+  "users":{
+    "2313":{"name":"Sara"},
+    "7839":{"name":"Andy"}
+  }
+}
+```
+
+A colon path would look like:
+
+```
+"users.:2313.name"    >> "Sara"
+```
+
+Supported types
+---------------
+
+Pretty much any type is supported:
+
+```go
+sjson.Set(`{"key":true}`, "key", nil)
+sjson.Set(`{"key":true}`, "key", false)
+sjson.Set(`{"key":true}`, "key", 1)
+sjson.Set(`{"key":true}`, "key", 10.5)
+sjson.Set(`{"key":true}`, "key", "hello")
+sjson.Set(`{"key":true}`, "key", []string{"hello", "world"})
+sjson.Set(`{"key":true}`, "key", map[string]interface{}{"hello":"world"})
+```
+
+When a type is not recognized, SJSON will fallback to the `encoding/json` Marshaller.
+
+
+Examples
+--------
+
+Set a value from empty document:
+```go
+value, _ := sjson.Set("", "name", "Tom")
+println(value)
+
+// Output:
+// {"name":"Tom"}
+```
+
+Set a nested value from empty document:
+```go
+value, _ := sjson.Set("", "name.last", "Anderson")
+println(value)
+
+// Output:
+// {"name":{"last":"Anderson"}}
+```
+
+Set a new value:
+```go
+value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.first", "Sara")
+println(value)
+
+// Output:
+// {"name":{"first":"Sara","last":"Anderson"}}
+```
+
+Update an existing value:
+```go
+value, _ := sjson.Set(`{"name":{"last":"Anderson"}}`, "name.last", "Smith")
+println(value)
+
+// Output:
+// {"name":{"last":"Smith"}}
+```
+
+Set a new array value:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.2", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol","Sara"]
+```
+
+Append an array value by using the `-1` key in a path:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.-1", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol","Sara"]
+```
+
+Append an array value that is past the end:
+```go
+value, _ := sjson.Set(`{"friends":["Andy","Carol"]}`, "friends.4", "Sara")
+println(value)
+
+// Output:
+// {"friends":["Andy","Carol",null,null,"Sara"]
+```
+
+Delete a value:
+```go
+value, _ := sjson.Delete(`{"name":{"first":"Sara","last":"Anderson"}}`, "name.first")
+println(value)
+
+// Output:
+// {"name":{"last":"Anderson"}}
+```
+
+Delete an array value:
+```go
+value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.1")
+println(value)
+
+// Output:
+// {"friends":["Andy"]}
+```
+
+Delete the last array value:
+```go
+value, _ := sjson.Delete(`{"friends":["Andy","Carol"]}`, "friends.-1")
+println(value)
+
+// Output:
+// {"friends":["Andy"]}
+```

+
+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *

+*  Contributor, or anyone who distributes Covered Software as          *

+*  including, without limitation, damages for lost profits, loss of    *

+*  extent applicable law prohibits such limitation. Some               *
+*  jurisdictions do not allow the exclusion or limitation of           *
+*  incidental or consequential damages, so this exclusion and          *

+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.

+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses

+## v0.15.0 (2023-03-16)
+
+### beta.3 (2023-03-15)
+
+* **Breaking change *(appservice)*** Removed `Load()` and `AppService.Init()`
+  functions. The struct should just be created with `Create()` and the relevant
+  fields should be filled manually.
+* **Breaking change *(appservice)*** Removed public `HomeserverURL` field and
+  replaced it with a `SetHomeserverURL` method.
+* *(appservice)* Added support for unix sockets for homeserver URL and
+  appservice HTTP server.
+* *(client)* Changed request logging to log durations as floats instead of
+  strings (using zerolog's `Dur()`, so the exact output can be configured).
+* *(bridge)* Changed zerolog to use nanosecond precision timestamps.
+* *(crypto)* Added message index to log after encrypting/decrypting megolm
+  events, and when failing to decrypt due to duplicate index.
+* *(sqlstatestore)* Fixed warning log for rooms that don't have encryption
+  enabled.
+
+### beta.2 (2023-03-02)
+
+* *(bridge)* Fixed building with `nocrypto` tag.
+* *(bridge)* Fixed legacy logging config migration not disabling file writer
+  when `file_name_format` was empty.
+* *(bridge)* Added option to require room power level to run commands.
+* *(event)* Added structs for [MSC3952]: Intentional Mentions.
+* *(util/variationselector)* Added `FullyQualify` method to add necessary emoji
+  variation selectors without adding all possible ones.
+
+[MSC3952]: https://github.com/matrix-org/matrix-spec-proposals/pull/3952
+
+### beta.1 (2023-02-24)
+
+* Bumped minimum Go version to 1.19.
+* **Breaking changes**
+  * *(all)* Switched to zerolog for logging.
+    * The `Client` and `Bridge` structs still include a legacy logger for
+      backwards compatibility.
+  * *(client, appservice)* Moved `SQLStateStore` from appservice module to the
+    top-level (client) module.
+  * *(client, appservice)* Removed unused `Typing` map in `SQLStateStore`.
+  * *(client)* Removed unused `SaveRoom` and `LoadRoom` methods in `Storer`.
+  * *(client, appservice)* Removed deprecated `SendVideo` and `SendImage` methods.
+  * *(client)* Replaced `AppServiceUserID` field with `SetAppServiceUserID` boolean.
+    The `UserID` field is used as the value for the query param.
+  * *(crypto)* Renamed `GobStore` to `MemoryStore` and removed the file saving
+    features. The data can still be persisted, but the persistence part must be
+    implemented separately.
+  * *(crypto)* Removed deprecated `DeviceIdentity` alias
+    (renamed to `id.Device` long ago).
+  * *(client)* Removed `Stringifable` interface as it's the same as `fmt.Stringer`.
+* *(client)* Renamed `Storer` interface to `SyncStore`. A type alias exists for
+  backwards-compatibility.
+* *(crypto/cryptohelper)* Added package for a simplified crypto interface for clients.
+* *(example)* Added e2ee support to example using crypto helper.
+* *(client)* Changed default syncer to stop syncing on `M_UNKNOWN_TOKEN` errors.
+
+## v0.14.0 (2023-02-16)
+
+* **Breaking change *(format)*** Refactored the HTML parser `Context` to have
+  more data.
+* *(id)* Fixed escaping path components when forming matrix.to URLs
+  or `matrix:` URIs.
+* *(bridge)* Bumped default timeouts for decrypting incoming messages.
+* *(bridge)* Added `RawArgs` to commands to allow accessing non-split input.
+* *(bridge)* Added `ReplyAdvanced` to commands to allow setting markdown
+  settings.
+* *(event)* Added `notifications` key to `PowerLevelEventContent`.
+* *(event)* Changed `SetEdit` to cut off edit fallback if the message is long.
+* *(util)* Added `SyncMap` as a simple generic wrapper for a map with a mutex.
+* *(util)* Added `ReturnableOnce` as a wrapper for `sync.Once` with a return
+  value.
+
+## v0.13.0 (2023-01-16)
+
+* **Breaking change:** Removed `IsTyping` and `SetTyping` in `appservice.StateStore`
+  and removed the `TypingStateStore` struct implementing those methods.
+* **Breaking change:** Removed legacy fields in Beeper MSS events.
+* Added knocked rooms to sync response structs.
+* Added wrapper for `/timestamp_to_event` endpoint added in Matrix v1.6.
+* Fixed MSC3870 uploads not failing properly after using up the max retry count.
+* Fixed parsing non-positive ordered list start positions in HTML parser.
+
+## v0.12.4 (2022-12-16)
+
+* Added `SendReceipt` to support private read receipts and thread receipts in
+  the same function. `MarkReadWithContent` is now deprecated.
+* Changed media download methods to return errors if the server returns a
+  non-2xx status code.
+* Removed legacy `sql_store_upgrade.Upgrade` method. Using `store.DB.Upgrade()`
+  after `NewSQLCryptoStore(...)` is recommended instead (the bridge module does
+  this automatically).
+* Added missing `suggested` field to `m.space.child` content struct.
+* Added `device_unused_fallback_key_types` to `/sync` response and appservice
+  transaction structs.
+* Changed `ReqSetReadMarkers` to omit empty fields.
+* Changed bridge configs to force `sqlite3-fk-wal` instead of `sqlite3`.
+* Updated bridge helper to close database connection when stopping.
+* Fixed read receipt and account data endpoints sending `null` instead of an
+  empty object as the body when content isn't provided.
+
+## v0.12.3 (2022-11-16)
+
+* **Breaking change:** Added logging for row iteration in the dbutil package.
+  This changes the return type of `Query` methods from `*sql.Rows` to a new
+  `dbutil.Rows` interface.
+* Added flag to disable wrapping database upgrades in a transaction (e.g. to
+  allow setting `PRAGMA`s for advanced table mutations on SQLite).
+* Deprecated `MessageEventContent.GetReplyTo` in favor of directly using
+  `RelatesTo.GetReplyTo`. RelatesTo methods are nil-safe, so checking if
+  RelatesTo is nil is not necessary for using those methods.
+* Added wrapper for space hierarchyendpoint (thanks to [@mgcm] in [#100]).
+* Added bridge config option to handle transactions asynchronously.
+* Added separate channels for to-device events in appservice transaction
+  handler to avoid blocking to-device events behind normal events.
+* Added `RelatesTo.GetNonFallbackReplyTo` utility method to get the reply event
+  ID, unless the reply is a thread fallback.
+* Added `event.TextToHTML` as an utility method to HTML-escape a string and
+  replace newlines with `<br/>`.
+* Added check to bridge encryption helper to make sure the e2ee keys are still
+  on the server. Synapse is known to sometimes lose keys randomly.
+* Changed bridge crypto syncer to crash on `M_UNKNOWN_TOKEN` errors instead of
+  retrying forever pointlessly.
+* Fixed verifying signatures of fallback one-time keys.
+
+[@mgcm]: https://github.com/mgcm
+[#100]: https://github.com/mautrix/go/pull/100
+
+## v0.12.2 (2022-10-16)
+
+* Added utility method to redact bridge commands.
+* Added thread ID field to read receipts to match Matrix v1.4 changes.
+* Added automatic fetching of media repo config at bridge startup to make it
+  easier for bridges to check homeserver media size limits.
+* Added wrapper for the `/register/available` endpoint.
+* Added custom user agent to all requests mautrix-go makes. The value can be
+  customized by changing the `DefaultUserAgent` variable.
+* Implemented [MSC3664], [MSC3862] and [MSC3873] in the push rule evaluator.
+* Added workaround for potential race conditions in OTK uploads when using
+  appservice encryption ([MSC3202]).
+* Fixed generating registrations to use `.+` instead of `[0-9]+` in the
+  username regex.
+* Fixed panic in megolm session listing methods if the store contains withheld
+  key entries.
+* Fixed missing header in bridge command help messages.
+
+[MSC3664]: https://github.com/matrix-org/matrix-spec-proposals/pull/3664
+[MSC3862]: https://github.com/matrix-org/matrix-spec-proposals/pull/3862
+[MSC3873]: https://github.com/matrix-org/matrix-spec-proposals/pull/3873
+
+## v0.12.1 (2022-09-16)
+
+* Bumped minimum Go version to 1.18.
+* Added `omitempty` for a bunch of fields in response structs to make them more
+  usable for server implementations.
+* Added `util.RandomToken` to generate GitHub-style access tokens with checksums.
+* Added utilities to call the push gateway API.
+* Added `unread_notifications` and [MSC2654] `unread_count` fields to /sync
+  response structs.
+* Implemented [MSC3870] for uploading and downloading media directly to/from an
+  external media storage like S3.
+* Fixed dbutil database ownership checks on SQLite.
+* Fixed typo in unauthorized encryption key withheld code
+  (`m.unauthorized` -> `m.unauthorised`).
+* Fixed [MSC2409] support to have a separate field for to-device events.
+
+[MSC2654]: https://github.com/matrix-org/matrix-spec-proposals/pull/2654
+[MSC3870]: https://github.com/matrix-org/matrix-spec-proposals/pull/3870
+
+## v0.12.0 (2022-08-16)
+
+* **Breaking change:** Switched `Client.UserTyping` to take a `time.Duration`
+  instead of raw `int64` milliseconds.
+* **Breaking change:** Removed custom reply relation type and switched to using
+  the wire format (nesting in `m.in_reply_to`).
+* Added device ID to appservice OTK count map to match updated [MSC3202].
+  This is also a breaking change, but the previous incorrect behavior wasn't
+  implemented by anything other than mautrix-syncproxy/imessage.
+* (There are probably other breaking changes too).
+* Added database utility and schema upgrade framework
+  * Originally from mautrix-whatsapp, but usable for non-bridges too
+  * Includes connection wrapper to log query durations and mutate queries for
+    SQLite compatibility (replacing `$x` with `?x`).
+* Added bridge utilities similar to mautrix-python. Currently includes:
+  * Crypto helper
+  * Startup flow
+  * Command handling and some standard commands
+  * Double puppeting things
+  * Generic parts of config, basic config validation
+  * Appservice SQL state store
+* Added alternative markdown spoiler parsing extension that doesn't support
+  reasons, but works better otherwise.
+* Added Discord underline markdown parsing extension (`_foo_` -> <u>foo</u>).
+* Added support for parsing spoilers and color tags in the HTML parser.
+* Added support for mutating plain text nodes in the HTML parser.
+* Added room version field to the create room request struct.
+* Added empty JSON object as default request body for all non-GET requests.
+* Added wrapper for `/capabilities` endpoint.
+* Added `omitempty` markers for lots of structs to make the structs easier to
+  use on the server side too.
+* Added support for registering to-device event handlers via the default
+  Syncer's `OnEvent` and `OnEventType` methods.
+* Fixed `CreateEventContent` using the wrong field name for the room version
+  field.
+* Fixed `StopSync` not immediately cancelling the sync loop if it was sleeping
+  after a failed sync.
+* Fixed `GetAvatarURL` always returning the current user's avatar instead of
+  the specified user's avatar (thanks to [@nightmared] in [#83]).
+* Improved request logging and added new log when a request finishes.
+* Crypto store improvements:
+  * Deleted devices are now kept in the database.
+  * Made ValidateMessageIndex atomic.
+* Moved `appservice.RandomString` to the `util` package and made it use
+  `crypto/rand` instead of `math/rand`.
+* Significantly improved cross-signing validation code.
+  * There are now more options for required trust levels,
+    e.g. you can set `SendKeysMinTrust` to `id.TrustStateCrossSignedTOFU`
+    to trust the first cross-signing master key seen and require all devices
+    to be signed by that key.
+  * Trust state of incoming messages is automatically resolved and stored in
+    `evt.Mautrix.TrustState`. This can be used to reject incoming messages from
+    untrusted devices.

+[#83]: https://github.com/mautrix/go/pull/83
+
+## v0.11.1 (2023-01-15)
+
+* Fixed parsing non-positive ordered list start positions in HTML parser
+  (backport of the same fix in v0.13.0).
+
+## v0.11.0 (2022-05-16)
+
+* Bumped minimum Go version to 1.17.
+* Switched from `/r0` to `/v3` paths everywhere.
+  * The new `v3` paths are implemented since Synapse 1.48, Dendrite 0.6.5, and
+    Conduit 0.4.0. Servers older than these are no longer supported.
+* Switched from blackfriday to goldmark for markdown parsing in the `format`
+  module and added spoiler syntax.
+* Added `EncryptInPlace` and `DecryptInPlace` methods for attachment encryption.
+  In most cases the plain/ciphertext is not necessary after en/decryption, so
+  the old `Encrypt` and `Decrypt` are deprecated.
+* Added wrapper for `/rooms/.../aliases`.
+* Added utility for adding/removing emoji variation selectors to match
+  recommendations on reactions in Matrix.
+* Added support for async media uploads ([MSC2246]).
+* Added automatic sleep when receiving 429 error
+  (thanks to [@ownaginatious] in [#44]).
+* Added support for parsing spec version numbers from the `/versions` endpoint.
+* Removed unstable prefixed constant used for appservice login.
+* Fixed URL encoding not working correctly in some cases.

+
+## v0.10.12 (2022-03-16)
+
+* Added option to use a different `Client` to send invites in
+  `IntentAPI.EnsureJoined`.
+* Changed `MessageEventContent` struct to omit empty `msgtype`s in the output
+  JSON, as sticker events shouldn't have that field.
+* Fixed deserializing the `thumbnail_file` field in `FileInfo`.
+* Fixed bug that broke `SQLCryptoStore.FindDeviceByKey`.
+
+## v0.10.11 (2022-02-16)
+
+* Added automatic updating of state store from `IntentAPI` calls.
+* Added option to ignore cache in `IntentAPI.EnsureJoined`.
+* Added `GetURLPreview` as a wrapper for the `/preview_url` media repo endpoint.
+* Moved base58 module inline to avoid pulling in btcd as a dependency.
+
+## v0.10.10 (2022-01-16)
+
+* Added event types and content structs for server ACLs and moderation policy
+  lists (thanks to [@qua3k] in [#59] and [#60]).
+* Added optional parameter to `Client.LeaveRoom` to pass a `reason` field.
+
+[#59]: https://github.com/mautrix/go/pull/59
+[#60]: https://github.com/mautrix/go/pull/60
+
+## v0.10.9 (2022-01-04)
+
+* **Breaking change:** Changed `Messages()` to take a filter as a parameter
+  instead of using the syncer's filter (thanks to [@qua3k] in [#55] and [#56]).
+  * The previous filter behavior was completely broken, as it sent a whole
+    filter instead of just a RoomEventFilter.
+  * Passing `nil` as the filter is fine and will disable filtering
+    (which is equivalent to what it did before with the invalid filter).
+* Added `Context()` wrapper for the `/context` API (thanks to [@qua3k] in [#54]).
+* Added utility for converting media files with ffmpeg.

+
+## v0.10.8 (2021-12-30)
+
+* Added `OlmSession.Describe()` to wrap `olm_session_describe`.
+* Added trace logs to log olm session descriptions when encrypting/decrypting
+  to-device messages.
+* Added space event types and content structs.
+* Added support for power level content override field in `CreateRoom`.

+
+## v0.10.7 (2021-12-16)
+
+* Changed `Client.RedactEvent` to allow arbitrary fields in redaction request.
+

+  key requests.
+* Added automatic Olm session recreation if an incoming message fails to decrypt.
+* Changed `Login` to only omit request content from logs if there's a password
+  or token (appservice logins don't have sensitive content).
+
+## v0.10.4 (2021-11-25)
+
+* Added `reason` field to invite and unban requests
+  (thanks to [@ptman] in [#48]).
+* Fixed `AppService.HasWebsocket()` returning `true` even after websocket has
+  disconnected.
+
+[@ptman]: https://github.com/ptman
+[#48]: https://github.com/mautrix/go/pull/48
+
+## v0.10.3 (2021-11-18)
+
+* Added logs about incoming appservice transactions.
+* Added support for message send checkpoints (as HTTP requests, similar to the
+  bridge state reporting system).
+
+## v0.10.2 (2021-11-15)
+
+* Added utility method for finding the first supported login flow matching any
+  of the given types.
+* Updated registering appservice ghosts to use `inhibit_login` flag to prevent
+  lots of unnecessary access tokens from being created.
+  * If you want to log in as an appservice ghost, you should use [MSC2778]'s
+    appservice login (e.g. like [mautrix-whatsapp does for e2be](https://github.com/mautrix/whatsapp/blob/v0.2.1/crypto.go#L143-L149)).
+
+## v0.10.1 (2021-11-05)
+
+* Removed direct dependency on `pq`
+  * In order to use some more efficient queries on postgres, you must set
+    `crypto.PostgresArrayWrapper = pq.Array` if you want to use both postgres
+    and e2ee.
+* Added temporary hack to ignore state events with the MSC2716 historical flag
+  (to be removed after [matrix-org/synapse#11265] is merged)
+* Added received transaction acknowledgements for websocket appservice
+  transactions.
+* Added automatic fallback to move `prev_content` from top level to the
+  standard location inside `unsigned`.
+
+[matrix-org/synapse#11265]: https://github.com/matrix-org/synapse/pull/11265
+
+## v0.9.31 (2021-10-27)

+  structs from being included in the JSON.
+
+[MSC2716]: https://github.com/matrix-org/matrix-spec-proposals/pull/2716
+
+## v0.9.29 (2021-09-30)
+
+* Added `client.State` method to get full room state.
+* Added bridge info structs and event types ([MSC2346]).
+* Made response handling more customizable.
+* Fixed type of `AuthType` constants.
+
+[MSC2346]: https://github.com/matrix-org/matrix-spec-proposals/pull/2346
+
+## v0.9.28 (2021-09-30)
+
+* Added `X-Mautrix-Process-ID` to appservice websocket headers to help debug
+  issues where multiple instances are connecting to the server at the same time.
+
+## v0.9.27 (2021-09-23)
+
+* Fixed Go 1.14 compatibility (broken in v0.9.25).
+* Added GitHub actions CI to build, test and check formatting on Go 1.14-1.17.
+
+## v0.9.26 (2021-09-21)
+
+* Added default no-op logger to `Client` in order to prevent panic when the
+  application doesn't set a logger.
+
+## v0.9.25 (2021-09-19)
+
+* Disabled logging request JSON for sensitive requests like `/login`,
+  `/register` and other UIA endpoints. Logging can still be enabled by
+  setting `MAUTRIX_LOG_SENSITIVE_CONTENT` to `yes`.
+* Added option to store new homeserver URL from `/login` response well-known data.
+* Added option to stream big sync responses via disk to maybe reduce memory usage.
+* Fixed trailing slashes in homeserver URL breaking all requests.
+
+## v0.9.24 (2021-09-03)

+  instead of only the most recent one.
+
+## v0.9.21 (2021-08-25)
+
+* Added liveness and readiness endpoints to appservices.
+  * The endpoints are the same as mautrix-python:
+    `/_matrix/mau/live` and `/_matrix/mau/ready`
+  * Liveness always returns 200 and an empty JSON object by default,
+    but it can be turned off by setting `appservice.Live` to `false`.
+  * Readiness defaults to returning 500, and it can be switched to 200
+    by setting `appservice.Ready` to `true`.
+
+## v0.9.20 (2021-08-19)
+
+* Added crypto store migration for converting all `VARCHAR(255)` columns
+  to `TEXT` in Postgres databases.

+
+## v0.9.18 (2021-08-16)

+  but without requiring the `Client` instance.
+
+## v0.9.17 (2021-07-25)
+
+* Fixed handling OTK counts and device lists coming in through the appservice
+  transaction websocket.
+* Updated OlmMachine to ignore OTK counts intended for other devices.
+

+  appservice package.
+* Added support for sending commands through appservice websocket.
+* Changed error message JSON field name in appservice error responses to
+  conform with standard Matrix errors (`message` -> `error`).
+
+[MSC3202]: https://github.com/matrix-org/matrix-spec-proposals/pull/3202
+
+## v0.9.14 (2021-06-17)
+
+* Added default implementation of `PillConverter` in HTML parser utility.
+
+## v0.9.13 (2021-06-15)
+
+* Added support for parsing and generating encoded matrix.to URLs and `matrix:` URIs ([MSC2312](https://github.com/matrix-org/matrix-doc/pull/2312)).
+* Updated HTML parser to use new URI parser for parsing user/room pills.
+
+## v0.9.12 (2021-05-18)

+  and `allowMarkdown` are `false`.
+
+## v0.9.9 (2021-04-26)
+
+* Updated appservice `StartWebsocket` to return websocket close info.
+
+## v0.9.8 (2021-04-20)
+
+* Added methods for getting room tags and account data.
+
+## v0.9.7 (2021-04-19)
+
+* **Breaking change (crypto):** `SendEncryptedToDevice` now requires an event
+  type parameter. Previously it only allowed sending events of type
+  `event.ToDeviceForwardedRoomKey`.
+* Added content structs for VoIP events.
+* Added global mutex for Olm decryption
+  (previously it was only used for encryption).
+
+## v0.9.6 (2021-04-15)
+
+* Added option to retry all HTTP requests when encountering a HTTP network
+  error or gateway error response (502/503/504)
+  * Disabled by default, you need to set the `DefaultHTTPRetries` field in
+    the `AppService` or `Client` struct to enable.
+  * Can also be enabled with `FullRequest`s `MaxAttempts` field.
+
+## v0.9.5 (2021-04-06)

+
+## v0.9.2 (2021-03-15)
+
+* Fixed type of presence state constants (thanks to [@babolivier] in [#30]).
+* Implemented presence state fetching methods (thanks to [@babolivier] in [#29]).

+
+## v0.9.1 (2021-03-11)
+
+* Fixed appservice register request hiding actual errors due to UIA error handling.
+
+## v0.9.0 (2021-03-04)
+
+* **Breaking change (manual API requests):** `MakeFullRequest` now takes a
+  `FullRequest` struct instead of individual parameters. `MakeRequest`'s
+  parameters are unchanged.
+* **Breaking change (manual /sync):** `SyncRequest` now requires a `Context`
+  parameter.
+* **Breaking change (end-to-bridge encryption):**
+  the `uk.half-shot.msc2778.login.application_service` constant used for
+  appservice login ([MSC2778]) was renamed from `AuthTypeAppservice`
+  to `AuthTypeHalfyAppservice`.
+  * The `AuthTypeAppservice` constant now contains `m.login.application_service`,
+    which is currently only used for registrations, but will also be used for
+    login once MSC2778 lands in the spec.
+* Fixed appservice registration requests to include `m.login.application_service`
+  as the `type` (re [matrix-org/synapse#9548]).
+* Added wrapper for `/logout/all`.

+
+## v0.8.1 (2021-02-09)

+  See <https://github.com/mautrix/wsproxy> for the server-side implementation.
+* Fixed error when removing the room avatar.

+[#23]: https://github.com/mautrix/go/pull/23
+
+## v0.8.0 (2020-12-24)
+
+* **Breaking change:** the `RateLimited` field in the `Registration` struct is
+  now a pointer, so that it can be omitted entirely.
+* Merged initial SSSS/cross-signing code by [@nikofil]. Interactive verification
+  doesn't work, but the other things mostly do.
+* Added support for authorization header auth in appservices ([MSC2832]).
+* Added support for receiving ephemeral events directly ([MSC2409]).
+* Fixed `SendReaction()` and other similar methods in the `Client` struct.
+* Fixed crypto cgo code panicking in Go 1.15.3+.

+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.

+# String globbing in Go
+
+[![GoDoc](https://godoc.org/github.com/zyedidia/glob?status.svg)](http://godoc.org/github.com/zyedidia/glob)
+
+This package adds support for globs in Go.
+
+It simply converts glob expressions to regexps. I try to follow the standard defined [here](http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_13).
+
+# Example
+
+```go
+package main
+
+import "github.com/zyedidia/glob"
+
+func main() {
+    glob, err := glob.Compile("{*.go,*.c}")
+    if err != nil {
+        // Error
+    }
+
+    glob.Match([]byte("test.c"))   // true
+    glob.Match([]byte("hello.go")) // true
+    glob.Match([]byte("test.d"))   // false
+}
+```
+
+You can call all the same functions on a glob that you can call on a regexp.

+Package base58 provides an API for working with modified base58 and Base58Check
+encodings.
+
+# Modified Base58 Encoding
+
+Standard base58 encoding is similar to standard base64 encoding except, as the
+name implies, it uses a 58 character alphabet which results in an alphanumeric
+string and allows some characters which are problematic for humans to be
+excluded.  Due to this, there can be various base58 alphabets.
+
+The modified base58 alphabet used by Bitcoin, and hence this package, omits the
+0, O, I, and l characters that look the same in many fonts and are therefore
+hard to humans to distinguish.
+
+# Base58Check Encoding Scheme
+
+The Base58Check encoding scheme is primarily used for Bitcoin addresses at the
+time of this writing, however it can be used to generically encode arbitrary
+byte arrays into human-readable strings along with a version byte that can be
+used to differentiate the same payload.  For Bitcoin addresses, the extra
+version is used to differentiate the network of otherwise identical public keys
+which helps prevent using an address intended for one network on another.
