+# go-toml
+
+Go library for the [TOML](https://github.com/mojombo/toml) format.
+
+This library supports TOML version
+[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
+
+[![GoDoc](https://godoc.org/github.com/pelletier/go-toml?status.svg)](http://godoc.org/github.com/pelletier/go-toml)
+[![license](https://img.shields.io/github/license/pelletier/go-toml.svg)](https://github.com/pelletier/go-toml/blob/master/LICENSE)
+[![Build Status](https://travis-ci.org/pelletier/go-toml.svg?branch=master)](https://travis-ci.org/pelletier/go-toml)
+[![Coverage Status](https://coveralls.io/repos/github/pelletier/go-toml/badge.svg?branch=master)](https://coveralls.io/github/pelletier/go-toml?branch=master)
+[![Go Report Card](https://goreportcard.com/badge/github.com/pelletier/go-toml)](https://goreportcard.com/report/github.com/pelletier/go-toml)
+
+## Features
+
+Go-toml provides the following features for using data parsed from TOML documents:
+
+* Load TOML documents from files and string data
+* Easily navigate TOML structure using Tree
+* Mashaling and unmarshaling to and from data structures
+* Line & column position data for all parsed elements
+* [Query support similar to JSON-Path](query/)
+* Syntax errors contain line and column numbers
+
+## Import
+
+```go
+import "github.com/pelletier/go-toml"
+```
+
+## Usage example
+
+Read a TOML document:
+
+```go
+config, _ := toml.Load(`
+[postgres]
+user = "pelletier"
+password = "mypassword"`)
+// retrieve data directly
+user := config.Get("postgres.user").(string)
+
+// or using an intermediate object
+postgresConfig := config.Get("postgres").(*toml.Tree)
+password := postgresConfig.Get("password").(string)
+```
+
+Or use Unmarshal:
+
+```go
+type Postgres struct {
+    User     string
+    Password string
+}
+type Config struct {
+    Postgres Postgres
+}
+
+doc := []byte(`
+[Postgres]
+User = "pelletier"
+Password = "mypassword"`)
+
+config := Config{}
+toml.Unmarshal(doc, &config)
+fmt.Println("user=", config.Postgres.User)
+```
+
+Or use a query:
+
+```go
+// use a query to gather elements without walking the tree
+q, _ := query.Compile("$..[user,password]")
+results := q.Execute(config)
+for ii, item := range results.Values() {
+    fmt.Println("Query result %d: %v", ii, item)
+}
+```
+
+## Documentation
+
+The documentation and additional examples are available at
+[godoc.org](http://godoc.org/github.com/pelletier/go-toml).
+
+## Tools
+
+Go-toml provides two handy command line tools:
+
+* `tomll`: Reads TOML files and lint them.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomll
+    tomll --help
+    ```
+* `tomljson`: Reads a TOML file and outputs its JSON representation.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomljson
+    tomljson --help
+    ```
+
+## Contribute
+
+Feel free to report bugs and patches using GitHub's pull requests system on
+[pelletier/go-toml](https://github.com/pelletier/go-toml). Any feedback would be
+much appreciated!
+
+### Run tests
+
+You have to make sure two kind of tests run:
+
+1. The Go unit tests
+2. The TOML examples base
+
+You can run both of them using `./test.sh`.
+
+### Fuzzing
+
+The script `./fuzz.sh` is available to
+run [go-fuzz](https://github.com/dvyukov/go-fuzz) on go-toml.
+
+## Versioning
+
+Go-toml follows [Semantic Versioning](http://semver.org/). The supported version
+of [TOML](https://github.com/toml-lang/toml) is indicated at the beginning of
+this document. The last two major versions of Go are supported
+(see [Go Release Policy](https://golang.org/doc/devel/release.html#policy)).

-// Package query performs JSONPath-like queries on a TOML document.
-//
-// The query path implementation is based loosely on the JSONPath specification:
-// http://goessner.net/articles/JsonPath/.
-//
-// The idea behind a query path is to allow quick access to any element, or set
-// of elements within TOML document, with a single expression.
-//
-//   result, err := query.CompileAndExecute("$.foo.bar.baz", tree)
-//
-// This is roughly equivalent to:
-//
-//   next := tree.Get("foo")
-//   if next != nil {
-//     next = next.Get("bar")
-//     if next != nil {
-//       next = next.Get("baz")
-//     }
-//   }
-//   result := next
-//
-// err is nil if any parsing exception occurs.
-//
-// If no node in the tree matches the query, result will simply contain an empty list of
-// items.
-//
-// As illustrated above, the query path is much more efficient, especially since
-// the structure of the TOML file can vary.  Rather than making assumptions about
-// a document's structure, a query allows the programmer to make structured
-// requests into the document, and get zero or more values as a result.
-//
-// Query syntax
-//
-// The syntax of a query begins with a root token, followed by any number
-// sub-expressions:
-//
-//   $
-//                    Root of the TOML tree.  This must always come first.
-//   .name
-//                    Selects child of this node, where 'name' is a TOML key
-//                    name.
-//   ['name']
-//                    Selects child of this node, where 'name' is a string
-//                    containing a TOML key name.
-//   [index]
-//                    Selcts child array element at 'index'.
-//   ..expr
-//                    Recursively selects all children, filtered by an a union,
-//                    index, or slice expression.
-//   ..*
-//                    Recursive selection of all nodes at this point in the
-//                    tree.
-//   .*
-//                    Selects all children of the current node.
-//   [expr,expr]
-//                    Union operator - a logical 'or' grouping of two or more
-//                    sub-expressions: index, key name, or filter.
-//   [start:end:step]
-//                    Slice operator - selects array elements from start to
-//                    end-1, at the given step.  All three arguments are
-//                    optional.
-//   [?(filter)]
-//                    Named filter expression - the function 'filter' is
-//                    used to filter children at this node.
-//
-// Query Indexes And Slices
-//
-// Index expressions perform no bounds checking, and will contribute no
-// values to the result set if the provided index or index range is invalid.
-// Negative indexes represent values from the end of the array, counting backwards.
-//
-//   // select the last index of the array named 'foo'
-//   query.CompileAndExecute("$.foo[-1]", tree)
-//
-// Slice expressions are supported, by using ':' to separate a start/end index pair.
-//
-//   // select up to the first five elements in the array
-//   query.CompileAndExecute("$.foo[0:5]", tree)
-//
-// Slice expressions also allow negative indexes for the start and stop
-// arguments.
-//
-//   // select all array elements.
-//   query.CompileAndExecute("$.foo[0:-1]", tree)
-//
-// Slice expressions may have an optional stride/step parameter:
-//
-//   // select every other element
-//   query.CompileAndExecute("$.foo[0:-1:2]", tree)
-//
-// Slice start and end parameters are also optional:
-//
-//   // these are all equivalent and select all the values in the array
-//   query.CompileAndExecute("$.foo[:]", tree)
-//   query.CompileAndExecute("$.foo[0:]", tree)
-//   query.CompileAndExecute("$.foo[:-1]", tree)
-//   query.CompileAndExecute("$.foo[0:-1:]", tree)
-//   query.CompileAndExecute("$.foo[::1]", tree)
-//   query.CompileAndExecute("$.foo[0::1]", tree)
-//   query.CompileAndExecute("$.foo[:-1:1]", tree)
-//   query.CompileAndExecute("$.foo[0:-1:1]", tree)
-//
-// Query Filters
-//
-// Query filters are used within a Union [,] or single Filter [] expression.
-// A filter only allows nodes that qualify through to the next expression,
-// and/or into the result set.
-//
-//   // returns children of foo that are permitted by the 'bar' filter.
-//   query.CompileAndExecute("$.foo[?(bar)]", tree)
-//
-// There are several filters provided with the library:
-//
-//   tree
-//          Allows nodes of type Tree.
-//   int
-//          Allows nodes of type int64.
-//   float
-//          Allows nodes of type float64.
-//   string
-//          Allows nodes of type string.
-//   time
-//          Allows nodes of type time.Time.
-//   bool
-//          Allows nodes of type bool.
-//
-// Query Results
-//
-// An executed query returns a Result object.  This contains the nodes
-// in the TOML tree that qualify the query expression.  Position information
-// is also available for each value in the set.
-//
-//   // display the results of a query
-//   results := query.CompileAndExecute("$.foo.bar.baz", tree)
-//   for idx, value := results.Values() {
-//       fmt.Println("%v: %v", results.Positions()[idx], value)
-//   }
-//
-// Compiled Queries
-//
-// Queries may be executed directly on a Tree object, or compiled ahead
-// of time and executed discretely.  The former is more convenient, but has the
-// penalty of having to recompile the query expression each time.
-//
-//   // basic query
-//   results := query.CompileAndExecute("$.foo.bar.baz", tree)
-//
-//   // compiled query
-//   query, err := toml.Compile("$.foo.bar.baz")
-//   results := query.Execute(tree)
-//
-//   // run the compiled query again on a different tree
-//   moreResults := query.Execute(anotherTree)
-//
-// User Defined Query Filters
-//
-// Filter expressions may also be user defined by using the SetFilter()
-// function on the Query object.  The function must return true/false, which
-// signifies if the passed node is kept or discarded, respectively.
-//
-//   // create a query that references a user-defined filter
-//   query, _ := query.Compile("$[?(bazOnly)]")
-//
-//   // define the filter, and assign it to the query
-//   query.SetFilter("bazOnly", func(node interface{}) bool{
-//       if tree, ok := node.(*Tree); ok {
-//           return tree.Has("baz")
-//       }
-//       return false  // reject all other node types
-//   })
-//
-//   // run the query
-//   query.Execute(tree)
