Specification

Please read the full specification. This section will attempt to break down the essence of what it tries to achieve.

Only XDG_RUNTIME_DIR is set by default through pam_systemd. It is up to the user to explicitly define the other variables, using absolute paths that point to existing directories.

User directories

XDG_CONFIG_HOME
- Where user-specific configurations should be written (analogous to /etc).
- Should default to $HOME/.config.

XDG_CACHE_HOME
- Where user-specific non-essential (cached) data should be written (analogous to /var/cache).
- Should default to $HOME/.cache.

XDG_DATA_HOME
- Where user-specific data files should be written (analogous to /usr/share).
- Should default to $HOME/.local/share.

XDG_RUNTIME_DIR
- Used for non-essential, user-specific data files such as sockets, named pipes, etc.
- Not required to have a default value; warnings should be issued if not set or equivalents provided.
- Must be owned by the user with an access mode of 0700.
- Filesystem fully featured by standards of OS.
- Must be on the local filesystem.
- May be subject to periodic cleanup.
- Modified every 6 hours or set sticky bit if persistence is desired.
- Can only exist for the duration of the user's login.
- Should not store large files as it may be mounted as a tmpfs.

System directories

XDG_DATA_DIRS
- List of directories seperated by : (analogous to PATH).
- Should default to /usr/local/share:/usr/share.

XDG_CONFIG_DIRS
- List of directories seperated by : (analogous to PATH).
- Should default to /etc/xdg.

Support

This section exists to catalog the growing set of software using the XDG Base Directory Specification introduced in 2003. This is here to demonstrate the viability of this specification by listing commonly found dotfiles and their support status. For those not currently supporting the Base Directory Specification, workarounds will be demonstrated to emulate it instead.

The workarounds will be limited to anything not involving patching the source, executing code stored in environment variables or compile-time options. The rationale for this is that configurations should be portable across systems and having compile-time options prevent that.

Hopefully this will provide a source of information about exactly what certain kinds of dotfiles are and where they come from.

Contributing

When contributing make sure to use the correct section.

Nothing should require code evaluation (such as vim and VIMINIT), patches or compile-time options to gain support and anything which does must be deemed hardcoded. Additionally if the process is too error prone or difficult, such as Haskell's cabal or Eclipse, they should also be considered as hardcoded.

The first column should be either a link to an internal article, a Template:Pkg or a Template:AUR.
The second column is for any legacy files and directories the project had (one per line), this is done so people can find them even if they are no longer read.
In the third, try to find the commit or version a project switched to XDG Base Directory or any open discussions and include them in the next two columns (two per line).
The last column should include any appropriate workarounds or solutions. Please verify that your solution is correct and functional.

wget	`~/.wgetrc ~/.wget-hsts`			`$ export WGETRC="$XDG_CONFIG_HOME/wgetrc" and add the following as an alias for wget: $ wget --hsts-file="$XDG_CACHE_HOME/wget-hsts" or set the hsts-file variable with an absolute path as wgetrc does not support environment variables: $ echo hsts-file \= "$XDG_CACHE_HOME"/wget-hsts >> "$XDG_CONFIG_HOME/wgetrc"`
wine	`~/.wine`		[117]	Winetricks uses XDG-alike location below for WINEPREFIX management: `$ mkdir -p "$XDG_DATA_HOME"/wineprefixes $ export WINEPREFIX="$XDG_DATA_HOME"/wineprefixes/default`
xbindkeys	`~/.xbindkeysrc`			`$ xbindkeys -f "$XDG_CONFIG_HOME"/xbindkeys/config`
xorg-xauth	`~/.Xauthority`			`$ export XAUTHORITY="$XDG_RUNTIME_DIR"/Xauthority`
xinit	`~/.xinitrc ~/.xserverrc`		[118]	`$ export XINITRC="$XDG_CONFIG_HOME"/X11/xinitrc $ export XSERVERRC="$XDG_CONFIG_HOME"/X11/xserverrc` Note that these variables are respected by xinit, but not by startx. Instead, specify the filename as an argument: `$ startx "$XDG_CONFIG_HOME/X11/xinitrc" -- "$XDG_CONFIG_HOME/X11/xserverrc" vt1`
xorg-xrdb	`~/.Xresources ~/.Xdefaults`			Ultimately you should be using `Xresources` and since these resources are loaded via `xrdb` you can specify a path such as `$ xrdb -load ~/.config/X11/xresources`.
z	`~/.z`		[119]	`$ export _Z_DATA="$XDG_DATA_HOME/z"`

Hardcoded

Application	Legacy Path	Discussion	Notes
adb	`~/.android/`	[120]	`$ export ANDROID_SDK_HOME="$XDG_CONFIG_HOME"/android`
AMule	`~/.aMule`
Android Studio	`~/.AndroidStudio2.3 ~/.android/ ~/.java/`
anthy	`~/.anthy`	[121]
Apache Directory Studio	`~/.ApacheDirectoryStudio`
ARandR	`~/.screenlayout`
Arduino	`~/.arduino15 ~/.jssc`	won't fix
Audacity	`~/.audacity-data/`
Avidemux	`~/.avidemux6`
Bash	`~/.bashrc ~/.bash_history ~/.bash_profile ~/.bash_login ~/.bash_logout`	won't fix	`$ export HISTFILE="$XDG_DATA_HOME"/bash/history` A specified `bashrc` can be sourced from `/etc/bashrc`. Specify `--init-file <file>` as an alternative to `~/.bashrc` for interactive shells.
cabal	`~/.cabal/`	[122]	See discussion for potential workarounds. It is not very easy or straightforward but may be possible to emulate Base Directory compliance.
chatty^AUR	`~/.chatty/`	[123]
cmake	`~/.cmake/`		Used for the user package registry `~/.cmake/packages/<package>`, detailed in cmake-packages(7) and the Package registry wiki page. Looks like it's hardcoded, for example in cmFindPackageCommand.cxx.
Cinnamon	`~/.cinnamon/`	[124]
cryptomator^AUR	`~/.Cryptomator`	[125]
CUPS	`~/.cups/`	won't fix
darcs	`~/.darcs/`	[126]
dbus	`~/.dbus/`	[127]	This should be avoidable with kdbus [citation needed].
devede	`~/.devedeng`		Hardcoded here
Dia	`~/.dia/`
dotnet-sdk	`~/.dotnet/`	[128]
Eclipse	`~/.eclipse/`	[129]	Option `-Dosgi.configuration.area=@user.home/.config/..` overrides but must be added to `"$ECLIPSE_HOME"/eclipse.ini"` rather than command line which means you must have write access to `$ECLIPSE_HOME`. (Arch Linux hard-codes `$ECLIPSE_HOME` in `/usr/bin/eclipse`)
Emacs	`~/.emacs ~/.emacs.d/`	[130]	It's possible to set `HOME`, but it has unexpected side effects. So far the most promising approach is modifying another Emacs environment variable to alter the load path and author your own site file which can manually load up your init file, but it changes the load process significantly.
Fetchmail	`~/.fetchmailrc`
Firefox	`~/.mozilla/`	[131]
Flatpak	`~/.var/`	[132] [133] won't fix
GHC	`~/.ghc`	[134]

Java OpenJFX	`~/.java/webview`
julia	`~/.juliarc.jl ~/.julia_history`	[141] [142]
Linux PAM	`~/.pam_environment`	[143]	Hardcoded in modules/pam_env/pam_env.c
lldb	`~/.lldb ~/.lldbinit`
mathomatic	`~/.mathomaticrc ~/.matho_history`		History can be moved by using `rlwrap mathomatic -r` with the `RLWRAP_HOME` environment set appropriately.
Minecraft	`~/.minecraft/`	[144]
Minetest	`~/.minetest/`	won't fix [145]
mongodb	`~/.mongorc.js ~/.dbshell`	[146]	This Stack Overflow thread suggests a partial workaround using command-line switch `--norc`.
Nestopia UE	`~/.nestopia/`	won't fix
	`~/.netrc`		Like `~/.ssh`, many programs expect this file to be here. These include projects like curl (`CURLOPT_NETRC_FILE`), ftp (`NETRC`), s-nail (`NETRC`), etc. While some of them offer alternative configurable locations, many do not such as w3m, wget and lftp.
NSS	`~/.pki`	[147]
OpenSSH	`~/.ssh`	won't fix	Assumed to be present by many ssh daemons and clients such as DropBear and OpenSSH.
palemoon	`~/.moonchild productions`	[148]
parsec-bin^AUR	`~/.parsec`
pcsxr^AUR	`~/.pcsxr`		A `-cfg` flag exists, but can only be set relative to `~/.pcsxr`.
perf	`~/.debug`		Hardcoded in tools/perf/util/config.c:29.
various shells and display managers	`~/.profile`
python	`~/.python_history`		All history from interactive sessions is saved to `~/.python_history` by default since version 3.4, custom path can still be set the same way as in older versions (see this example).
Qt Designer	`~/.designer`
racket	`~/.racketrc`
RedNotebook	`~/.rednotebook`
Remarkable	`~/.remarkable`
Ren'Py	`~/.renpy`	[149]
SANE	`~/.sane/`		`scanimage` creates a `.cal` file there
scribus	`~/.scribus`
SeaMonkey	`~/.mozilla/`	[150]
simplescreenrecorder	`~/.ssr/`	[151]	Author seems against this feature.
Solfege	`~/.solfege ~/.solfegerc ~/lessonfiles`	[152]
SpamAssassin	`~/.spamassassin`
spectrwm	`~/.spectrwm`
SQLite	`~/.sqlite_history ~/.sqliterc`	[153]	`$ export SQLITE_HISTORY=$XDG_DATA_HOME/sqlite_history` `$ sqlite3 -init "$XDG_CONFIG_HOME"/sqlite3/sqliterc`
Steam	`~/.steam ~/.steampath ~/.steampid`	[154]	Many game engines (Unity 3D, Unreal) follow the specification, but then individual game publishers hardcode the paths in Steam Auto-Cloud causing game-saves to sync to the wrong directory.
TeamSpeak	`~/.ts3client`
texinfo	`~/.infokey`		`$ info --init-file "$XDG_CONFIG_HOME/infokey"`
TeXmacs	`~/.TeXmacs`
Thunderbird	`~/.thunderbird/`	[155]
tllocalmgr	`~/.texlive`
vim	`~/.vim ~/.vimrc ~/.viminfo`		Since 7.3.1178 vim will search for `~/.vim/vimrc` if `~/.vimrc` is not found. `$ mkdir -p "$XDG_CACHE_HOME"/vim/{undo,swap,backup}` "$XDG_CONFIG_HOME"/vim/vimrc set undodir=$XDG_CACHE_HOME/vim/undo set directory=$XDG_CACHE_HOME/vim/swap set backupdir=$XDG_CACHE_HOME/vim/backup set viminfo+='1000,n$XDG_CACHE_HOME/vim/viminfo set runtimepath=$XDG_CONFIG_HOME/vim,$VIMRUNTIME,$XDG_CONFIG_HOME/vim/after ~/.profile export VIMINIT=":source $XDG_CONFIG_HOME"/vim/vimrc https://tlvince.com/vim-respect-xdg
vimperator	`~/.vimperatorrc`	[156]	`$ export VIMPERATOR_INIT=":source $XDG_CONFIG_HOME/vimperator/vimperatorrc"` `$ export VIMPERATOR_RUNTIME="$XDG_CONFIG_HOME"/vimperator`
w3m	`~/.w3m`	[157]
wpa_cli	`~/.wpa_cli_history`
xdg-utils	`~/.gnome`	[158]	For some reason the script `xdg-desktop-menu` hard-codes `gnome_user_dir="$HOME/.gnome/apps"`. This is used by chromium among others.
xombrero	`~/.xombrero`	[159]
YARD	`~/.yard`	[160]	Would accept Pull Request if anyone want to implement it.
zenmap nmap	`~/.zenmap`	[161] [162]
zsh	`~/.zshrc ~/.zprofile ~/.zshenv ~/.zlogin ~/.zlogout ~/.histfile ~/.zcompdump`	[163]	Consider exporting `ZDOTDIR=$HOME/.config/zsh` in `~/.zshenv` (this is hardcoded due to the bootstrap problem). You could also add this to `/etc/zsh/zshenv` and avoid the need for any dotfiles in your `HOME`. Doing this however requires root privilege which may not be viable and is system-wide. `$ export HISTFILE="$XDG_DATA_HOME"/zsh/history` `$ compinit -d $XDG_CACHE_HOME/zsh/zcompdump-$ZSH_VERSION` [164] /!\ The folder needs to exist
