Provides an implementation of the XDG Base Directory Specification. The specification defines a set of standard paths for storing application files, including data and configuration files. For portability and flexibility reasons, applications should use the XDG defined locations instead of hardcoding paths.

The package also includes the locations of well known user directories and an implementation of the state directory proposal. Windows, macOS and most flavors of Unix are supported.

Full documentation can be found at: https://pkg.go.dev/github.com/adrg/xdg.

Installation

go get github.com/adrg/xdg

Default locations

The package defines sensible defaults for XDG variables which are empty or not present in the environment.

Usage

XDG Base Directory

package main

import (
	"log"

	"github.com/adrg/xdg"
)

func main() {
	// XDG Base Directory paths.
	log.Println("Home data directory:", xdg.DataHome)
	log.Println("Data directories:", xdg.DataDirs)
	log.Println("Home config directory:", xdg.ConfigHome)
	log.Println("Config directories:", xdg.ConfigDirs)
	log.Println("Cache directory:", xdg.CacheHome)
	log.Println("Runtime directory:", xdg.RuntimeDir)

	// Non-standard directories.
	log.Println("Home state directory:", xdg.StateHome)
	log.Println("Application directories:", xdg.ApplicationDirs)
	log.Println("Font directories:", xdg.FontDirs)

	// Obtain a suitable location for application config files.
	// ConfigFile takes one parameter which must contain the name of the file,
	// but it can also contain a set of parent directories. If the directories
	// don't exist, they will be created relative to the base config directory.
	configFilePath, err := xdg.ConfigFile("appname/config.yaml")
	if err != nil {
		log.Fatal(err)
	}
	log.Println("Save the config file at:", configFilePath)

	// For other types of application files use:
	// xdg.DataFile()
	// xdg.CacheFile()
	// xdg.RuntimeFile()
	// xdg.StateFile()

	// Finding application config files.
	// SearchConfigFile takes one parameter which must contain the name of
	// the file, but it can also contain a set of parent directories relative
	// to the config search paths (xdg.ConfigHome and xdg.ConfigDirs).
	configFilePath, err = xdg.SearchConfigFile("appname/config.yaml")
	if err != nil {
		log.Fatal(err)
	}
	log.Println("Config file was found at:", configFilePath)

	// For other types of application files use:
	// xdg.SearchDataFile()
	// xdg.SearchCacheFile()
	// xdg.SearchRuntimeFile()
	// xdg.SearchStateFile()
}

XDG user directories

package main

import (
	"log"

	"github.com/adrg/xdg"
)

func main() {
	// XDG user directories.
	log.Println("Desktop directory:", xdg.UserDirs.Desktop)
	log.Println("Download directory:", xdg.UserDirs.Download)
	log.Println("Documents directory:", xdg.UserDirs.Documents)
	log.Println("Music directory:", xdg.UserDirs.Music)
	log.Println("Pictures directory:", xdg.UserDirs.Pictures)
	log.Println("Videos directory:", xdg.UserDirs.Videos)
	log.Println("Templates directory:", xdg.UserDirs.Templates)
	log.Println("Public directory:", xdg.UserDirs.PublicShare)
}
