Best way to add environmental variable to set Fish configuration directory.

[frederickjh]

This is related to #1 and this comment.

Fish normally finds or puts its configuration files in ~/.config/fish. This can be changed by setting the environmental variable `XDG_CONFIG_HOME'.

Using this line from entrypoint.sh as starting point,

export XXH_HOME=`dirname $CURRENT_DIR/../../../../p`

We could add something like this after it,

export XDG_CONFIG_HOME=`dirname $CURRENT_DIR/../../../../.xxh-shell-fish/config`

to set the configuration directory for the Fish shell.

Common way is to place default config in the xxh-shell directory.

Xonsh shell example:

1. xonshrc.xsh is in the shell directory - it will be copied to build dir by build.sh and will be in ~/.xxh/xxh/shells/xxh-shell-xonsh-appimage/build directory along with entrypoint.sh
2. when you do xxh myhost it upload build dir to the host and calls entrypoint.sh which calls xonshrc.xsh file when run xonsh
3. xonshrc.xsh init/source/import plugins

On the step 2 and 3 inside shellrc and pluginrc scripts you can get the directory where this scripts are placed (or use global environment variable $XXH_HOME which set in entrypoint.sh).

If you need to copy config files from xxh-shell to $XXH_HOME to save this between xxh updates:

1. Add this files to build dir by modifying xxh-shell-fish/build.sh
2. Add the code to fishrc.fish which check that $XXH_HOME/.fish-configs is not exists and make copy from ~/.xxh/xxh/shells/xxh-shell-fish/build/fish-configs to $XXH_HOME/.fish-configs.
3. If $XXH_HOME/.fish-configs exists then load configs from there.

But in common case it's not needed. Configs could be a part of the xxh-shell-fish/build directory and in bash, zsh, xonsh I avoided using $XXH_HOME. My be my cases were simple.
