Re: What is XDG_CONFIG_HOME for exactly?

My understanding is that git reads the priority of configuration as follows:

1. <local_repo>/.git/config
2. $HOME/.gitconfig
3. $XDG_CONFIG_HOME/git/config

$HOME/.gitconfig is the traditional Unix location for config files. It
was the only per-user config files in early versions of Git.

$XDG_CONFIG_HOME/git/config is the location following freedesktop's XDG
standard. It has several advantages (you can version and/or share
individual $XDG_CONFIG_HOME/git/ as a whole directory, while it's much
harder to version all ~/.git* files individually for example).

You typically want to use either one or the other.

4. system level git config (not sure exactly where this is; not
relevant to me on Windows)

This is relevant if you use a shared machine and your sysadmin wants to
have the same configuration for all users.

As a follow-up, I tested the following in my .bashrc:


# Utilize different GIT settings based on platform
if [[ $OSTYPE == 'msys' || $OSTYPE == 'cygwin' ]]; then
    echo 'Using WINDOWS specific git settings'
    export XDG_CONFIG_HOME=.config-windows

You need an absolute directory here:

export XDG_CONFIG_HOME=$HOME/.config-windows

Then, I'd suggest that $XDG_CONFIG_HOME/git/config contains a

[include]
    path = ../../.config-shared/git/config

so that you can factor out common portions of your config file into
.config-shared/git/config and keep machine-specific portions in
~/.config-{windows,linux}.
