In case you are, like me, tired of applications polluting your homedir with config and data files, the XDB Base Directory Specification (ArchWiki) has your back.
You probably saw the
~/.config directory already, and in fact, many
programs can be told to use this directory instead of polluting your
homedir. The ArchWiki page has a list of many applications and which
environment variables need to be set to change the location of their
~/.config/environment.d/xdg.conf currently looks like this:
# Explicitly set the location of the XDG directories. XDG_CONFIG_HOME=$HOME/.config XDG_CACHE_HOME=$HOME/.cache XDG_DATA_HOME=$HOME/.local/share # Set program specific locations.
