Subject: [PATCH v9 1/3] cache.h: Introduce a generic "xdg_config_home_for(…)" function
Date: Fri, 27 Aug 2021 23:02:53 +0200	[thread overview]
Message-ID: <20210827210255.12565-2-lenaic@lhuard.fr> (raw)
In-Reply-To: <20210827210255.12565-1-lenaic@lhuard.fr>

Current implementation of `xdg_config_home(filename)` returns
`$XDG_CONFIG_HOME/git/$filename`, with the `git` subdirectory inserted
between the `XDG_CONFIG_HOME` environment variable and the parameter.

This patch introduces a `xdg_config_home_for(subdir, filename)` function
which is more generic. It only concatenates "$XDG_CONFIG_HOME", or
"$HOME/.config" if the former isn’t defined, with the parameters,
without adding `git` in between.

`xdg_config_home(filename)` is now implemented by calling
`xdg_config_home_for("git", filename)` but this new generic function can
be used to compute the configuration directory of other programs.
