[Lua + GLib] User directories

GLibUserDirectories.lua

local lgi = require("lgi")
local GLib = lgi.require("GLib", "2.0")

--[[ Explanation

  Some multimedia apps (music players, for example) that uses GLib and related libraries (Gtk,
  GObject, GStreamer, etc...) commonly auto-detects user directories that contains specific
  things like music, videos, pictures and documents. That's nice, but... How is it done?
  Well... Here's the answer:

]]

-- GLib has the function 'get_user_special_dir()' and takes an argument of type GLib.UserDirectory:
local DesktopDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_DESKTOP)
local DownloadsDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_DOWNLOAD)
local DocumentsDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_DOCUMENTS)
local MusicDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_MUSIC)
local PicturesDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_PICTURES)
local PublicShareDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_PUBLIC_SHARE)
local TemplatesDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_TEMPLATES)
local VideosDir = GLib.get_user_special_dir(GLib.UserDirectory.DIRECTORY_VIDEOS)

-- And that's it! Check out the result:
print(DesktopDir)
print(DownloadsDir)
print(DocumentsDir)
print(MusicDir)
print(PicturesDir)
print(PublicShareDir)
print(TemplatesDir)
print(VideosDir)
