XDG Base Directory

This article summarizes the XDG Base Directory specification in #Specification and tracks software support in #Support.

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 according to the specification.

See Environment variables#Globally for information on defining variables.

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

System directories

  • XDG_DATA_DIRS
    • List of directories separated by : (analogous to PATH).
    • Should default to /usr/local/share:/usr/share.
  • XDG_CONFIG_DIRS
    • List of directories separated 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 error prone or difficult, it should also be classified 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.

Legacy paths have precedence over XDG paths. Emacs will never create XDG_CONFIG_HOME/emacs/. Workaround for 26.3 or older: It's possible to set HOME, but it has unexpected side effects.

You can get the new socket directory using gpgconf --dry-run --create-socketdir and have to modify the systemd user units to listen on the correct sockets accordingly.

This is not a perfect solution - you will have to create symlinks to your downloads and other XDG directories to get the browser to use them properly. However, it is workable. Of course, you could do this in any directory, not just $XDG_DATA_HOME

openscad ~/.OpenSCAD 7c3077b0f [142] Does not fully honour XDG Base Directory Specification, see [143]

It is required to create both directories: mkdir "$XDG_CONFIG_HOME/pg" && mkdir "$XDG_CACHE_HOME/pg"

PulseAudio ~/.esd_auth Very likely generated by the module-esound-protocol-unix.so module. It can be configured to use a different location but it makes much more sense to just comment out this module in /etc/pulse/default.pa or "$XDG_CONFIG_HOME"/pulse/default.pa.

The directory needs to be created manually

mkdir "$XDG_CONFIG_HOME/wakatime"

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 [164] Winetricks uses XDG-alike location below for WINEPREFIX management:

xbindkeys ~/.xbindkeysrc xbindkeys -f "$XDG_CONFIG_HOME"/xbindkeys/config
xorg-xauth ~/.Xauthority export XAUTHORITY="$XDG_RUNTIME_DIR"/Xauthority

Note that LightDM does not allow you to change this variable. If you change it nonetheless, you will not be able to login. Use startx instead or configure LightDM. According to [165] SLiM has ~/.Xauthority hardcoded.

xinit ~/.xinitrc, ~/.xserverrc [166] 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.
Xorg ~/.xsession, ~/.xsessionrc, ~/.Xsession, ~/.xsession-errors These can be added as part of your Xorg init script (~/.xinitrc) or Xsession start script (which will often be based on /etc/X11/Xsession).

Depending on where you have configured your $XDG_CACHE_HOME, you made need to expand the paths yourself.

# xsession start script
USERXSESSION="$XDG_CACHE_HOME/X11/xsession"
USERXSESSIONRC="$XDG_CACHE_HOME/X11/xsessionrc"
ALTUSERXSESSION="$XDG_CACHE_HOME/X11/Xsession"
ERRFILE="$XDG_CACHE_HOME/X11/xsession-errors"

Unlike most other examples in this table, actual X11 init scripts will vary a lot between installations.
