Go, XDG, go!
|
||||
===========
|
||||
|
||||
This is `go-xdg`, a little library to help you use the `XDG`
|
||||
[base directory spec](http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html).
|
||||
|
||||
(There are other `XDG` specs, that might get included in time. Patches welcome.)
|
||||
|
||||
Sample usage
|
||||
------------
|
||||
|
||||
Let's say you are writing an app called “frobz”. It has a config file
|
||||
and a sqlite database. You'd do something like this:
|
||||
|
||||
configFileName, err := xdg.Config.Find("frobz/config.txt")
|
||||
if err == nil {
|
||||
// a config file exists! load it...
|
||||
}
|
||||
dbFileName, err := xdg.Data.Ensure("frobz/frobz.db")
|
||||
// now the file and all its directories exist; it's up to you to
|
||||
// determine if it's empty, etc.
|
||||
|
||||
|
||||
Resources
|
||||
---------
|
||||
|
||||
Both `Find` and `Ensure` take a `resource` to construct the path they return.
|
||||
|
||||
A resource is usually an application name (or a well-known shared resource
|
||||
pool name, such as `icons`), followed by a filename. However nothing in the
|
||||
standard nor in this library limits you to that; you may store e.g. your
|
||||
application's configuration in just `$XDG_CONFIG_HOME/application.conf` (in
|
||||
which case the "resource" here would be just `application.conf`), or in a
|
||||
sub-directory of an application-specific directory.
|
||||

||||

## TOML parser and encoder for Go with reflection
|
||||
|
||||
TOML stands for Tom's Obvious, Minimal Language. This Go package provides a
|
||||
reflection interface similar to Go's standard library `json` and `xml`
|
||||
packages. This package also supports the `encoding.TextUnmarshaler` and
|
||||
`encoding.TextMarshaler` interfaces so that you can define custom data
|
||||
representations. (There is an example of this below.)
|
||||
|
||||
Spec: https://github.com/toml-lang/toml
|
||||
|
||||
Compatible with TOML version
|
||||
[v0.4.0](https://github.com/toml-lang/toml/blob/master/versions/en/toml-v0.4.0.md)
|
||||
|
||||
Documentation: https://godoc.org/github.com/BurntSushi/toml
|
||||
|
||||
Installation:
|
||||
|
||||
```bash
|
||||
go get github.com/BurntSushi/toml
|
||||
```
|
||||
|
||||
Try the toml validator:
|
||||
|
||||
```bash
|
||||
go get github.com/BurntSushi/toml/cmd/tomlv
|
||||
tomlv some-toml-file.toml
|
||||
```
|
||||
|
||||
[](https://travis-ci.org/BurntSushi/toml) [](https://godoc.org/github.com/BurntSushi/toml)
|
||||
|
||||
### Testing
|
||||
|
||||
This package passes all tests in
|
||||
[toml-test](https://github.com/BurntSushi/toml-test) for both the decoder
|
||||
and the encoder.
|
||||
|
||||
### Examples
|
||||
|
||||
This package works similarly to how the Go standard library handles `XML`
|
||||
and `JSON`. Namely, data is loaded into Go values via reflection.
|
||||
|
||||
For the simplest example, consider some TOML file as just a list of keys
|
||||
and values:
|
||||
|
||||
```toml
|
||||
Age = 25
|
||||
Cats = [ "Cauchy", "Plato" ]
|
||||
Pi = 3.14
|
||||
Perfection = [ 6, 28, 496, 8128 ]
|
||||
DOB = 1987-07-05T05:45:00Z
|
||||
```
|
||||
|
||||
Which could be defined in Go as:
|
||||
|
||||
```go
|
||||
type Config struct {
|
||||
Age int
|
||||
Cats []string
|
||||
Pi float64
|
||||
Perfection []int
|
||||
DOB time.Time // requires `import time`
|
||||
}
|
||||
```
|
||||
|
||||
And then decoded with:
|
||||
|
||||
```go
|
||||
var conf Config
|
||||
if _, err := toml.Decode(tomlData, &conf); err != nil {
|
||||
// handle error
|
||||
}
|
||||
```
|
||||
|
||||
You can also use struct tags if your struct field name doesn't map to a TOML
|
||||
key value directly:
|
||||
|
||||
```toml
|
||||
some_key_NAME = "wat"
|
||||
```
|
||||
|
||||
```go
|
||||
type TOML struct {
|
||||
ObscureKey string `toml:"some_key_NAME"`
|
||||
}
|
||||
```
|
||||
|
||||
### Using the `encoding.TextUnmarshaler` interface
|
||||
|
||||
Here's an example that automatically parses duration strings into
|
||||
`time.Duration` values:
|
||||
|
||||
```toml
|
||||
[[song]]
|
||||
name = "Thunder Road"
|
||||
duration = "4m49s"
|
||||
|
||||
[[song]]
|
||||
name = "Stairway to Heaven"
|
||||
duration = "8m03s"
|
||||
```
|
||||
|
||||
Which can be decoded with:
|
||||
|
||||
```go
|
||||
type song struct {
|
||||
Name string
|
||||
Duration duration
|
||||
}
|
||||
type songs struct {
|
||||
Song []song
|
||||
}
|
||||
var favorites songs
|
||||
if _, err := toml.Decode(blob, &favorites); err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
for _, s := range favorites.Song {
|
||||
fmt.Printf("%s (%s)\n", s.Name, s.Duration)
|
||||
}
|
||||
```
|
||||
|
||||
And you'll also need a `duration` type that satisfies the
|
||||
`encoding.TextUnmarshaler` interface:
|
||||
|
||||
```go
|
||||
type duration struct {
|
||||
time.Duration
|
||||
}
|
||||
|
||||
func (d *duration) UnmarshalText(text []byte) error {
|
||||
var err error
|
||||
d.Duration, err = time.ParseDuration(string(text))
|
||||
return err
|
||||
}
|
||||
```
|
||||
|
||||
### More complex usage
|
||||
|
||||
Here's an example of how to load the example from the official spec page:
|
||||
|
||||
```toml
|
||||
# This is a TOML document. Boom.
|
||||
|
||||
title = "TOML Example"
|
||||
|
||||
[owner]
|
||||
name = "Tom Preston-Werner"
|
||||
organization = "GitHub"
|
||||
bio = "GitHub Cofounder & CEO\nLikes tater tots and beer."
|
||||
dob = 1979-05-27T07:32:00Z # First class dates? Why not?
|
||||
|
||||
[database]
|
||||
server = "192.168.1.1"
|
||||
ports = [ 8001, 8001, 8002 ]
|
||||
connection_max = 5000
|
||||
enabled = true
|
||||
|
||||
[servers]
|
||||
|
||||
# You can indent as you please. Tabs or spaces. TOML don't care.
|
||||
[servers.alpha]
|
||||
ip = "10.0.0.1"
|
||||
dc = "eqdc10"
|
||||
|
||||
[servers.beta]
|
||||
ip = "10.0.0.2"
|
||||
dc = "eqdc10"
|
||||
|
||||
[clients]
|
||||
data = [ ["gamma", "delta"], [1, 2] ] # just an update to make sure parsers support it
|
||||
|
||||
# Line breaks are OK when inside arrays
|
||||
hosts = [
|
||||
"alpha",
|
||||
"omega"
|
||||
]
|
||||
```
|
||||
|
||||
And the corresponding Go types are:
|
||||
|
||||
```go
|
||||
type tomlConfig struct {
|
||||
Title string
|
||||
Owner ownerInfo
|
||||
DB database `toml:"database"`
|
||||
Servers map[string]server
|
||||
Clients clients
|
||||
}
|
||||
|
||||
type ownerInfo struct {
|
||||
Name string
|
||||
Org string `toml:"organization"`
|
||||
Bio string
|
||||
DOB time.Time
|
||||
}
|
||||
|
||||
type database struct {
|
||||
Server string
|
||||
Ports []int
|
||||
ConnMax int `toml:"connection_max"`
|
||||
Enabled bool
|
||||
}
|
||||
|
||||
type server struct {
|
||||
IP string
|
||||
DC string
|
||||
}
|
||||
|
||||
type clients struct {
|
||||
Data [][]interface{}
|
||||
Hosts []string
|
||||
}
|
||||
```
|
||||
|
||||
Note that a case insensitive match will be tried if an exact match can't be
|
||||
found.
|
||||
|
||||
A working example of the above can be found in `_examples/example.{go,toml}`.

/*
|
||||
Package toml provides facilities for decoding and encoding TOML configuration
|
||||
files via reflection. There is also support for delaying decoding with
|
||||
the Primitive type, and querying the set of keys in a TOML document with the
|
||||
MetaData type.
|
||||
|
||||
The specification implemented: https://github.com/toml-lang/toml
|
||||
|
||||
The sub-command github.com/BurntSushi/toml/cmd/tomlv can be used to verify
|
||||
whether a file is a valid TOML document. It can also be used to print the
|
||||
type of each key in a TOML document.
|
||||
|
||||
Testing
|
||||
|
||||
There are two important types of tests used for this package. The first is
|
||||
contained inside '*_test.go' files and uses the standard Go unit testing
|
||||
framework. These tests are primarily devoted to holistically testing the
|
||||
decoder and encoder.
|
||||
|
||||
The second type of testing is used to verify the implementation's adherence
|
||||
to the TOML specification. These tests have been factored into their own
|
||||
project: https://github.com/BurntSushi/toml-test
|
||||
|
||||
The reason the tests are in a separate project is so that they can be used by
|
||||
any implementation of TOML. Namely, it is language agnostic.

|
||||
=======================================================================================================================================================================================================================================
|
||||
|
||||
## Quickstart
|
||||
|
||||
If you just want OS-sensible paths.
|
||||
```
|
||||
configDirs := xdg.ConfigDirs()
|
||||
dataPath := xdg.DataHome()
|
||||
cachePath := xdg.CacheHome()
|
||||
```
|
||||
|
||||
Alternatively you can create a context that would determine full paths for your application files.
|
||||
```
|
||||
app := xdg.App{Name: "someApp"}
|
||||
configFile := app.ConfigPath("someApp.toml")
|
||||
dataFile := app.DataPath("data.json")
|
||||
```
|
||||
|
||||
## Supported path types
|
||||
|
||||
This is a KISS implementation of the XDG Base Directory Specification. As of now it handles the following path types:
|
||||
- Data (`XDG_DATA_*`) for application-wide or user-wide data.
|
||||
- Config (`XDG_CONFIG_*`) for application-wide or user-wide config.
|
||||
- Cache (`XDG_CACHE_*`)for application-wide or user-wide cached data.
|
||||
|
||||
## Multi-OS
|
||||
|
||||
The specification is Linux centric but this implementation targets more: Linux, OSX and Windows. Default values has been chosen regarding both the specification and the OS conventions. Note than you can override these values with the corresponding environment variables.
|
||||
|
||||
There are a lot of OSes missing but supporting them implies a good knowledge of these conventions and philosophies, contributors maybe?
