# Contributing
## Issues
* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
* Please indicate the platform you are using fsnotify on.
* A code example to reproduce the problem is appreciated.
## Pull Requests
### Contributor License Agreement
fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
Please indicate that you have signed the CLA in your pull request.
### How fsnotify is Developed
* Development is done on feature branches.
* Tests are run on BSD, Linux, macOS and Windows.
* Pull requests are reviewed and [applied to master][am] using [hub][].
* Maintainers may modify or squash commits rather than asking contributors to.
* To issue a new release, the maintainers will:
* Update the CHANGELOG
* Tag a version, which will become available through gopkg.in.
### How to Fork
For smooth sailing, always use the original import path. Installing with `go get` makes this easy.
1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
2. Create your feature branch (`git checkout -b my-new-feature`)
3. Ensure everything works and the tests pass (see below)
4. Commit your changes (`git commit -am 'Add some feature'`)
Contribute upstream:
1. Fork fsnotify on GitHub
2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
3. Push to the branch (`git push fork my-new-feature`)
4. Create a new Pull Request on GitHub
This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
### Testing
fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
* When you're done, you will want to halt or destroy the Vagrant boxes.
Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
### Maintainers
Help maintaining fsnotify is welcome. To be a maintainer:
* Submit a pull request and sign the CLA as above.
* You must be able to run the test suite on Mac, Windows, Linux and BSD.
To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
All code changes should be internal pull requests.
Releases are tagged using [Semantic Versioning](http://semver.org/).

# File system notifications for Go
[![GoDoc](https://godoc.org/github.com/fsnotify/fsnotify?status.svg)](https://godoc.org/github.com/fsnotify/fsnotify) [![Go Report Card](https://goreportcard.com/badge/github.com/fsnotify/fsnotify)](https://goreportcard.com/report/github.com/fsnotify/fsnotify)
fsnotify utilizes [golang.org/x/sys](https://godoc.org/golang.org/x/sys) rather than `syscall` from the standard library. Ensure you have the latest version installed by running:
```console
go get -u golang.org/x/sys/...
```
Cross platform: Windows, Linux, BSD and macOS.
| Adapter | OS | Status |
| --------------------- | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| inotify | Linux 2.6.27 or later, Android\* | Supported [![Build Status](https://travis-ci.org/fsnotify/fsnotify.svg?branch=master)](https://travis-ci.org/fsnotify/fsnotify) |
| kqueue | BSD, macOS, iOS\* | Supported [![Build Status](https://travis-ci.org/fsnotify/fsnotify.svg?branch=master)](https://travis-ci.org/fsnotify/fsnotify) |
| ReadDirectoryChangesW | Windows | Supported [![Build Status](https://travis-ci.org/fsnotify/fsnotify.svg?branch=master)](https://travis-ci.org/fsnotify/fsnotify) |
| FSEvents | macOS | [Planned](https://github.com/fsnotify/fsnotify/issues/11) |
| FEN | Solaris 11 | [In Progress](https://github.com/fsnotify/fsnotify/issues/12) |
| fanotify | Linux 2.6.37+ | [Planned](https://github.com/fsnotify/fsnotify/issues/114) |
| USN Journals | Windows | [Maybe](https://github.com/fsnotify/fsnotify/issues/53) |
| Polling | *All* | [Maybe](https://github.com/fsnotify/fsnotify/issues/9) |
\* Android and iOS are untested.
Please see [the documentation](https://godoc.org/github.com/fsnotify/fsnotify) and consult the [FAQ](#faq) for usage information.
## API stability
fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
## Usage
```go
package main
import (
"log"
"github.com/fsnotify/fsnotify"
)
func main() {
watcher, err := fsnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
defer watcher.Close()
done := make(chan bool)
go func() {
for {
select {
case event, ok := <-watcher.Events:
if !ok {
return
}
log.Println("event:", event)
if event.Op&fsnotify.Write == fsnotify.Write {
log.Println("modified file:", event.Name)
}
case err, ok := <-watcher.Errors:
if !ok {
return
}
log.Println("error:", err)
}
}
}()
err = watcher.Add("/tmp/foo")
if err != nil {
log.Fatal(err)
}
<-done
}
```

## FAQ
**When a file is moved to another directory is it still being watched?**
No (it shouldn't be, unless you are watching where it was moved to).
**When I watch a directory, are all subdirectories watched as well?**
No, you must add watches for any directory you want to watch (a recursive watcher is on the roadmap [#18][]).
**Do I have to watch the Error and Event channels in a separate goroutine?**
As of now, yes. Looking into making this single-thread friendly (see [howeyc #7][#7])
**Why am I receiving multiple events for the same file on OS X?**
Spotlight indexing on OS X can result in multiple events (see [howeyc #62][#62]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#11][]).
**How many files can be watched at once?**
There are OS-specific limits as to how many watches can be created:
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit, reaching this limit results in a "no space left on device" error.
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.
**Why don't notifications work with NFS filesystems or filesystem in userspace (FUSE)?**
fsnotify requires support from underlying OS to work. The current NFS protocol does not provide network level support for file notifications.

**koanf** (pronounced _conf_; a play on the Japanese _Koan_) is a library for reading configuration from different sources in different formats in Go applications. It is a cleaner, lighter [alternative to spf13/viper](#alternative-to-viper) with better abstractions and extensibility and fewer dependencies.
koanf comes with built in support for reading configuration from files, command line flags, and environment variables, and can parse JSON, YAML, TOML, and Hashicorp HCL.
[![Build Status](https://travis-ci.com/knadh/koanf.svg?branch=master)](https://travis-ci.com/knadh/koanf) [![GoDoc](https://godoc.org/github.com/knadh/koanf?status.svg)](https://godoc.org/github.com/knadh/koanf)

### Concepts
- `koanf.Provider` is a generic interface that provides configuration, for example, from files, environment variables, HTTP sources, or anywhere. The configuration can either be raw bytes that a parser can parse, or it can be a nested map[string]interface{} that can be directly loaded.
- `koanf.Parser` is a generic interface that takes raw bytes, parses, and returns a nested map[string]interface{} representation. For example, JSON and YAML parsers.
- Once loaded into koanf, configuration are values queried by a delimited key path syntax. eg: `app.server.port`. Any delimiter can be chosen.
- Configuration from multiple sources can be loaded and merged into a koanf instance, for example, load from a file first and override certain values with flags from the command line.
With these two interface implementations, koanf can obtain a configuration from multiple sources and parse any format and make it available to an application.
### Reading config from files
```go
package main
import (
"fmt"
"log"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/parsers/yaml"
"github.com/knadh/koanf/providers/file"
)
// Global koanf instance. Use "." as the key path delimiter. This can be "/" or any character.
var k = koanf.New(".")
func main() {
// Load JSON config.
if err := k.Load(file.Provider("mock/mock.json"), json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
// Load YAML config and merge into the previously loaded config (because we can).
k.Load(file.Provider("mock/mock.yaml"), yaml.Parser())
fmt.Println("parent's name is = ", k.String("parent1.name"))
fmt.Println("parent's ID is = ", k.Int("parent1.id"))
}
```
### Watching files for changes
The `koanf.Provider` interface has a `Watch(cb)` method that asks a provider
to watch for changes and trigger the given callback that can live reload the
configuration.
Currently, `file.Provider` supports this.
```go
package main
import (
"fmt"
"log"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/parsers/yaml"
"github.com/knadh/koanf/providers/file"
)
// Global koanf instance. Use "." as the key path delimiter. This can be "/" or any character.
var k = koanf.New(".")
func main() {
// Load JSON config.
f := file.Provider("mock/mock.json")
if err := k.Load(f, json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
// Load YAML config and merge into the previously loaded config (because we can).
k.Load(file.Provider("mock/mock.yaml"), yaml.Parser())
fmt.Println("parent's name is = ", k.String("parent1.name"))
fmt.Println("parent's ID is = ", k.Int("parent1.id"))
// Watch the file and get a callback on change. The callback can do whatever,
// like re-load the configuration.
// File provider always returns a nil `event`.
f.Watch(func(event interface{}, err error) {
if err != nil {
log.Printf("watch error: %v", err)
return
}
log.Println("config changed. Reloading ...")
k.Load(f, json.Parser())
k.Print()
})
// Block forever (and manually make a change to mock/mock.json) to
// reload the config.
log.Println("waiting forever. Try making a change to mock/mock.json to live reload")
<-make(chan bool)
}
```
### Reading from command line
The following example shows the use of `posflag.Provider`, a wrapper over [spf13/pflag](/spf13/pflag) library, an advanced commandline lib. For Go's built in `flag` package, use `basicflag.Provider`.
```go
package main
import (
"fmt"
"log"
"os"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/toml"
"github.com/knadh/koanf/providers/file"
"github.com/knadh/koanf/providers/posflag"
flag "github.com/spf13/pflag"
)
// Global koanf instance. Use "." as the key path delimiter. This can be "/" or any character.
var k = koanf.New(".")
func main() {
// Use the POSIX compliant pflag lib instead of Go's flag lib.
f := flag.NewFlagSet("config", flag.ContinueOnError)
f.Usage = func() {
fmt.Println(f.FlagUsages())
os.Exit(0)
}
// Path to one or more config files to load into koanf along with some config params.
f.StringSlice("conf", []string{"mock/mock.toml"}, "path to one or more .toml config files")
f.String("time", "2020-01-01", "a time string")
f.String("type", "xxx", "type of the app")
f.Parse(os.Args[1:])
// Load the config files provided in the commandline.
cFiles, _ := f.GetStringSlice("conf")
for _, c := range cFiles {
if err := k.Load(file.Provider(c), toml.Parser()); err != nil {
log.Fatalf("error loading file: %v", err)
}
}
// "time" and "type" may have been loaded from the config file, but
// they can still be overridden with the values from the command line.
// The bundled posflag.Provider takes a flagset from the spf13/pflag lib.
// Passing the Koanf instance to posflag helps it deal with default command
// line flag values that are not present in conf maps from previously loaded
// providers.
if err := k.Load(posflag.Provider(f, ".", k), nil); err != nil {
log.Fatalf("error loading config: %v", err)
}
fmt.Println("time is = ", k.String("time"))
}
```
### Reading environment variables
```go
package main
import (
"fmt"
"log"
"strings"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/providers/env"
"github.com/knadh/koanf/providers/file"
)
// Global koanf instance. Use . as the key path delimiter. This can be / or anything.
var k = koanf.New(".")
func main() {
// Load JSON config.
if err := k.Load(file.Provider("mock/mock.json"), json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
// Load environment variables and merge into the loaded config.
// "MYVAR" is the prefix to filter the env vars by.
// "." is the delimiter used to represent the key hierarchy in env vars.
// The (optional, or can be nil) function can be used to transform
// the env var names, for instance, to lowercase them.
//
// For example, env vars: MYVAR_TYPE and MYVAR_PARENT1_CHILD1_NAME
// will be merged into the "type" and the nested "parent1.child1.name"
// keys in the config file here as we lowercase the key,
// replace `_` with `.` and strip the MYVAR_ prefix so that
// only "parent1.child1.name" remains.
k.Load(env.Provider("MYVAR_", ".", func(s string) string {
return strings.Replace(strings.ToLower(
strings.TrimPrefix(s, "MYVAR_")), "_", ".", -1)
}), nil)
fmt.Println("name is = ", k.String("parent1.child1.name"))
}
```
### Reading from an S3 bucket
```go
// Load JSON config from s3.
if err := k.Load(s3.Provider(s3.Config{
AccessKey: os.Getenv("AWS_S3_ACCESS_KEY"),
SecretKey: os.Getenv("AWS_S3_SECRET_KEY"),
Region: os.Getenv("AWS_S3_REGION"),
Bucket: os.Getenv("AWS_S3_BUCKET"),
ObjectKey: "dir/config.json",
}), json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
```
### Reading raw bytes
The bundled `rawbytes` Provider can be used to read arbitrary bytes from a source, like a database or an HTTP call.
```go
package main
import (
"fmt"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/providers/rawbytes"
)
// Global koanf instance. Use . as the key path delimiter. This can be / or anything.
var k = koanf.New(".")
func main() {
b := []byte(`{"type": "rawbytes", "parent1": {"child1": {"type": "rawbytes"}}}`)
k.Load(rawbytes.Provider(b), json.Parser())
fmt.Println("type is = ", k.String("parent1.child1.type"))
}
```
### Unmarshalling and marshalling
`Parser`s can be used to unmarshal and scan the values in a Koanf instance into a struct based on the field tags, and to marshal a Koanf instance back into serialized bytes, for example, back to JSON or YAML, to write back to files.
```go
package main
import (
"fmt"
"log"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/providers/file"
)
// Global koanf instance. Use . as the key path delimiter. This can be / or anything.
var (
k = koanf.New(".")
parser = json.Parser()
)
func main() {
// Load JSON config.
if err := k.Load(file.Provider("mock/mock.json"), parser); err != nil {
log.Fatalf("error loading config: %v", err)
}
// Structure to unmarshal nested conf to.
type childStruct struct {
Name string `koanf:"name"`
Type string `koanf:"type"`
Empty map[string]string `koanf:"empty"`
GrandChild struct {
Ids []int `koanf:"ids"`
On bool `koanf:"on"`
} `koanf:"grandchild1"`
}
var out childStruct
// Quick unmarshal.
k.Unmarshal("parent1.child1", &out)
fmt.Println(out)
// Unmarshal with advanced config.
out = childStruct{}
k.UnmarshalWithConf("parent1.child1", &out, koanf.UnmarshalConf{Tag: "koanf"})
fmt.Println(out)
// Marshal the instance back to JSON.
// The paser instance can be anything, eg: json.Paser(), yaml.Parser() etc.
b, _ := k.Marshal(parser)
fmt.Println(string(b))
}
```
### Unmarshalling with flat paths
Sometimes it is necessary to unmarshal an assortment of keys from various nested structures into a flat target structure. This is possible with the `UnmarshalConf.FlatPaths` flag.
```go
package main
import (
"fmt"
"log"
"github.com/knadh/koanf"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/providers/file"
)
// Global koanf instance. Use . as the key path delimiter. This can be / or anything.
var k = koanf.New(".")
func main() {
// Load JSON config.
if err := k.Load(file.Provider("mock/mock.json"), json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
type rootFlat struct {
Type string `koanf:"type"`
Empty map[string]string `koanf:"empty"`
Parent1Name string `koanf:"parent1.name"`
Parent1ID int `koanf:"parent1.id"`
Parent1Child1Name string `koanf:"parent1.child1.name"`
Parent1Child1Type string `koanf:"parent1.child1.type"`
Parent1Child1Empty map[string]string `koanf:"parent1.child1.empty"`
Parent1Child1Grandchild1IDs []int `koanf:"parent1.child1.grandchild1.ids"`
Parent1Child1Grandchild1On bool `koanf:"parent1.child1.grandchild1.on"`
}
// Unmarshal the whole root with FlatPaths: True.
var o1 rootFlat
k.UnmarshalWithConf("", &o1, koanf.UnmarshalConf{Tag: "koanf", FlatPaths: true})
fmt.Println(o1)
// Unmarshal a child structure of "parent1".
type subFlat struct {
Name string `koanf:"name"`
ID int `koanf:"id"`
Child1Name string `koanf:"child1.name"`
Child1Type string `koanf:"child1.type"`
Child1Empty map[string]string `koanf:"child1.empty"`
Child1Grandchild1IDs []int `koanf:"child1.grandchild1.ids"`
Child1Grandchild1On bool `koanf:"child1.grandchild1.on"`
}
var o2 subFlat
k.UnmarshalWithConf("parent1", &o2, koanf.UnmarshalConf{Tag: "koanf", FlatPaths: true})
fmt.Println(o2)
}
```
### Marshalling and writing config
It is possible to marshal and serialize the conf map into TOML, YAML etc.
### Setting default values.
koanf does not provide any special functions to set default values but uses the Provider interface to enable it.
#### From a map
The bundled `confmap` provider takes a `map[string]interface{}` that can be loaded into a koanf instance.
```go
package main
import (
"fmt"
"log"
"github.com/knadh/koanf"
"github.com/knadh/koanf/providers/confmap"
"github.com/knadh/koanf/providers/file"
"github.com/knadh/koanf/parsers/json"
"github.com/knadh/koanf/parsers/yaml"
)
// Global koanf instance. Use "." as the key path delimiter. This can be "/" or any character.
var k = koanf.New(".")
func main() {
// Load default values using the confmap provider.
// We provide a flat map with the "." delimiter.
// A nested map can be loaded by setting the delimiter to an empty string "".
k.Load(confmap.Provider(map[string]interface{}{
"parent1.name": "Default Name",
"parent3.name": "New name here",
}, "."), nil)
// Load JSON config on top of the default values.
if err := k.Load(file.Provider("mock/mock.json"), json.Parser()); err != nil {
log.Fatalf("error loading config: %v", err)
}
// Load YAML config and merge into the previously loaded config (because we can).
k.Load(file.Provider("mock/mock.yaml"), yaml.Parser())
fmt.Println("parent's name is = ", k.String("parent1.name"))
fmt.Println("parent's ID is = ", k.Int("parent1.id"))
}
```
#### From a struct
The bundled `structs` provider can be used to read data from a struct to load into a koanf instance.
```go
package main
import (
"fmt"
"github.com/knadh/koanf"
"github.com/knadh/koanf/providers/structs"
)
// Global koanf instance. Use "." as the key path delimiter. This can be "/" or any character.
var k = koanf.New(".")
type parentStruct struct {
Name string `koanf:"name"`
ID int `koanf:"id"`
Child1 childStruct `koanf:"child1"`
}
type childStruct struct {
Name string `koanf:"name"`
Type string `koanf:"type"`
Empty map[string]string `koanf:"empty"`
Grandchild1 grandchildStruct `koanf:"grandchild1"`
}
type grandchildStruct struct {
Ids []int `koanf:"ids"`
On bool `koanf:"on"`
}
type sampleStruct struct {
Type string `koanf:"type"`
Empty map[string]string `koanf:"empty"`
Parent1 parentStruct `koanf:"parent1"`
}
func main() {
// Load default values using the structs provider.
// We provide a struct along with the struct tag `koanf` to the
// provider.
k.Load(structs.Provider(sampleStruct{
Type: "json",
Empty: make(map[string]string),
Parent1: parentStruct{
Name: "parent1",
ID: 1234,
Child1: childStruct{
Name: "child1",
Type: "json",
Empty: make(map[string]string),
Grandchild1: grandchildStruct{
Ids: []int{1, 2, 3},
On: true,
},
},
},
}, "koanf"), nil)
fmt.Printf("name is = `%s`\n", k.String("parent1.child1.name"))
}
```
### Order of merge and key case senstivity
- Config keys are case-sensitive in koanf. For example, `app.server.port` and `APP.SERVER.port` are not the same.
- koanf does not impose any ordering on loading config from various providers. Every successive `Load()` or `Load()` merges new config into existing config. That means it is possible to load environment variables first, then files on top of it, and then command line variables on top of it, or any such order.
### Custom Providers and Parsers
A Provider can provide a nested map[string]interface{} config that can be loaded into koanf with `koanf.Load()` or raw bytes that can be parsed with a Parser (loaded using `koanf.Load()`.
Writing Providers and Parsers are easy. See the bundled implementations in the `providers` and `parses` directory.
## API
### Bundled providers

### Alternative to viper
koanf is a lightweight alternative to the popular [spf13/viper](https://github.com/spf13/viper). It does not aim to do everything viper does (such as mutating config maps and writing them back to files), but provides simpler primitives for reading and accessing configuration. It was written as a result of multiple stumbling blocks encountered with some of viper's fundamental flaws.
- viper breaks JSON, YAML, TOML, HCL language specs by [forcibly lowercasing keys](https://github.com/spf13/viper/pull/635).
- Significantly bloats [build sizes](https://github.com/knadh/koanf/wiki/Comparison-with-spf13-viper).
- Tightly couples config parsing with file extensions.
- Has poor semantics and abstractions. Commandline, env, file etc. and various parses are hardcoded in the core. There are no primitives that can be extended.
- Pulls a large number of [third party dependencies](https://github.com/spf13/viper/issues/707) into the core package. For instance, even if you do not use YAML or flags, the dependencies are still pulled as a result of the coupling.
- Imposes arbitrary ordering conventions (eg: flag -> env -> config etc.)
- `Get()` returns references to slices and maps. Mutations made outside change the underlying values inside the conf map.
- Does non-idiomatic things such as [throwing away O(1) on flat maps](https://github.com/spf13/viper/blob/3b4aca75714a37276c4b1883630bd98c02498b73/viper.go#L1524).
- There are a large number of [open issues](https://github.com/spf13/viper/issues).

# mapstructure [![Godoc](https://godoc.org/github.com/mitchellh/mapstructure?status.svg)](https://godoc.org/github.com/mitchellh/mapstructure)
mapstructure is a Go library for decoding generic map values to structures
and vice versa, while providing helpful error handling.
This library is most useful when decoding values from some data stream (JSON,
Gob, etc.) where you don't _quite_ know the structure of the underlying data
until you read a part of it. You can therefore read a `map[string]interface{}`
and use this library to decode it into the proper underlying native Go
structure.
## Installation
Standard `go get`:
```
$ go get github.com/mitchellh/mapstructure
```
## Usage & Example
For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
The `Decode` function has examples associated with it there.
## But Why?!
Go offers fantastic standard libraries for decoding formats such as JSON.
The standard method is to have a struct pre-created, and populate that struct
from the bytes of the encoded format. This is great, but the problem is if
you have configuration or an encoding that changes slightly depending on
specific fields. For example, consider this JSON:
```json
{
"type": "person",
"name": "Mitchell"
}
```
Perhaps we can't populate a specific structure without first reading
the "type" field from the JSON. We could always do two passes over the
decoding of the JSON (reading the "type" first, and the rest later).
However, it is much simpler to just decode this into a `map[string]interface{}`
structure, read the "type" key, then use something like this library
to decode it into the proper structure.

## Contributing
Thank you for your interest in go-toml! We appreciate you considering
contributing to go-toml!
The main goal is the project is to provide an easy-to-use TOML
implementation for Go that gets the job done and gets out of your way –
dealing with TOML is probably not the central piece of your project.
As the single maintainer of go-toml, time is scarce. All help, big or
small, is more than welcomed!
### Ask questions
Any question you may have, somebody else might have it too. Always feel
free to ask them on the [issues tracker][issues-tracker]. We will try to
answer them as clearly and quickly as possible, time permitting.
Asking questions also helps us identify areas where the documentation needs
improvement, or new features that weren't envisioned before. Sometimes, a
seemingly innocent question leads to the fix of a bug. Don't hesitate and
ask away!
### Improve the documentation
The best way to share your knowledge and experience with go-toml is to
improve the documentation. Fix a typo, clarify an interface, add an
example, anything goes!
The documentation is present in the [README][readme] and thorough the
source code. On release, it gets updated on [GoDoc][godoc]. To make a
change to the documentation, create a pull request with your proposed
changes. For simple changes like that, the easiest way to go is probably
the "Fork this project and edit the file" button on Github, displayed at
the top right of the file. Unless it's a trivial change (for example a
typo), provide a little bit of context in your pull request description or
commit message.
### Report a bug
Found a bug! Sorry to hear that :(. Help us and other track them down and
fix by reporting it. [File a new bug report][bug-report] on the [issues
tracker][issues-tracker]. The template should provide enough guidance on
what to include. When in doubt: add more details! By reducing ambiguity and
providing more information, it decreases back and forth and saves everyone
time.
### Code changes
Want to contribute a patch? Very happy to hear that!
First, some high-level rules:
* A short proposal with some POC code is better than a lengthy piece of
text with no code. Code speaks louder than words.
* No backward-incompatible patch will be accepted unless discussed.
Sometimes it's hard, and Go's lack of versioning by default does not
help, but we try not to break people's programs unless we absolutely have
to.
* If you are writing a new feature or extending an existing one, make sure
to write some documentation.
* Bug fixes need to be accompanied with regression tests.
* New code needs to be tested.
* Your commit messages need to explain why the change is needed, even if
already included in the PR description.
It does sound like a lot, but those best practices are here to save time
overall and continuously improve the quality of the project, which is
something everyone benefits from.
#### Get started
The fairly standard code contribution process looks like that:
1. [Fork the project][fork].
2. Make your changes, commit on any branch you like.
3. [Open up a pull request][pull-request]
4. Review, potential ask for changes.
5. Merge. You're in!
Feel free to ask for help! You can create draft pull requests to gather
some early feedback!
#### Run the tests
You can run tests for go-toml using Go's test tool: `go test ./...`.
When creating a pull requests, all tests will be ran on Linux on a few Go
versions (Travis CI), and on Windows using the latest Go version
(AppVeyor).
#### Style
Try to look around and follow the same format and structure as the rest of
the code. We enforce using `go fmt` on the whole code base.
---
### Maintainers-only
#### Merge pull request
Checklist:
* Passing CI.
* Does not introduce backward-incompatible changes (unless discussed).
* Has relevant doc changes.
* Has relevant unit tests.
1. Merge using "squash and merge".
2. Make sure to edit the commit message to keep all the useful information
nice and clean.
3. Make sure the commit title is clear and contains the PR number (#123).
#### New release
1. Go to [releases][releases]. Click on "X commits to master since this
release".
2. Make note of all the changes. Look for backward incompatible changes,
new features, and bug fixes.
3. Pick the new version using the above and semver.
4. Create a [new release][new-release].
5. Follow the same format as [1.1.0][release-110].

# go-toml
Go library for the [TOML](https://github.com/mojombo/toml) format.
This library supports TOML version
[v0.5.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.5.0.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://dev.azure.com/pelletierthomas/go-toml-ci/_apis/build/status/pelletier.go-toml?branchName=master)](https://dev.azure.com/pelletierthomas/go-toml-ci/_build/latest?definitionId=1&branchName=master)
[![codecov](https://codecov.io/gh/pelletier/go-toml/branch/master/graph/badge.svg)](https://codecov.io/gh/pelletier/go-toml)
[![Go Report Card](https://goreportcard.com/badge/github.com/pelletier/go-toml)](https://goreportcard.com/report/github.com/pelletier/go-toml)
[![FOSSA Status](https://app.fossa.io/api/projects/git%2Bgithub.com%2Fpelletier%2Fgo-toml.svg?type=shield)](https://app.fossa.io/projects/git%2Bgithub.com%2Fpelletier%2Fgo-toml?ref=badge_shield)
## 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
```
* `jsontoml`: Reads a JSON file and outputs a TOML representation.
```
go install github.com/pelletier/go-toml/cmd/jsontoml
jsontoml --help
```
### Docker image
Those tools are also availble as a Docker image from
[dockerhub](https://hub.docker.com/r/pelletier/go-toml). For example, to
use `tomljson`:
```
docker run -v $PWD:/workdir pelletier/go-toml tomljson /workdir/example.toml
```
Only master (`latest`) and tagged versions are published to dockerhub. You
can build your own image as usual:
```
docker build -t go-toml .
```
## 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
`go test ./...`
### 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)).

# Inline tables provide a more compact syntax for expressing tables. They are

// Package toml is a TOML parser and manipulation library.
//
// This version supports the specification as described in
// https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.5.0.md
//
// Marshaling
//
// Go-toml can marshal and unmarshal TOML documents from and to data
// structures.
//
// TOML document as a tree
//
// Go-toml can operate on a TOML document as a tree. Use one of the Load*
// functions to parse TOML data and obtain a Tree instance, then one of its
// methods to manipulate the tree.
//
// JSONPath-like queries
//
// The package github.com/pelletier/go-toml/query implements a system
// similar to JSONPath to quickly retrieve elements of a TOML document using a
// single expression. See the package documentation for more information.

Marshal returns the TOML encoding of v. Behavior is similar to the Go json
encoder, except that there is no concept of a Marshaler interface or MarshalTOML
function for sub-structs, and currently only definite types can be marshaled
(i.e. no `interface{}`).
The following struct annotations are supported:
toml:"Field" Overrides the field's name to output.
omitempty When set, empty values and groups are not emitted.
comment:"comment" Emits a # comment on the same line. This supports new lines.
commented:"true" Emits the value as commented.
Note that pointers are automatically assigned the "omitempty" option, as TOML
explicitly does not handle null values (saying instead the label should be
dropped).
Tree structural types and corresponding marshal types:
*Tree (*)struct, (*)map[string]interface{}
[]*Tree (*)[](*)struct, (*)[](*)map[string]interface{}
[]interface{} (as interface{}) (*)[]primitive, (*)[]([]interface{})
interface{} (*)primitive
Tree primitive types and corresponding marshal types:
uint64 uint, uint8-uint64, pointers to same
int64 int, int8-uint64, pointers to same
float64 float32, float64, pointers to same
string string, pointers to same
bool bool, pointers to same
time.LocalTime time.LocalTime{}, pointers to same
For additional flexibility, use the Encoder API.
