tmux and XDG_CONFIG_HOME #654

Is it possible for tmuxp to work with a tmux config in a "nonstandard" location? I like to keep my configs in XDG_CONFIG_HOME, which tmux does not seem to support (srsly). Aliasing tmux to tmux -f $XDG_CONFIG_HOME/tmux/config in the shell means that tmuxp does not read the tmux config. Also, creating a wrapper script called tmux that basically does the same thing as the alias,

#!/bin/bash

tmux -f "${XDG_CONFIG_HOME}"/tmux/config "${@}"

causes tmuxp to infinitely recurse tmux subprocesses, whereas tmux itself works fine with this mechanism.

I spent about 15 minutes reading through the source code and I couldn't find where to make any changes for this issue/feature. With a suggestion, I am willing to implement this myself.

@jfindlay This is a really good catch. As of 1.6 / 1.7 master:

tmuxp commands (e.g. tmuxp load) don't pass through the -f (tmux config file) to tmux. tmuxp already passes through -2 (256 colors), -8, -L (socket_name), -S (socket_path) to tmux

I spent about 15 minutes reading through the source code and I couldn't find where to make any changes for this issue/feature. With a suggestion, I am willing to implement this myself.

We'd do it in cli.py in command_load (CLI entrypoint) and load_workspace.

We can accept an -f / --file as an arg. We'd need to do this at t = Server so the libtmux client used refers to the tmux config file:

tmuxp/tmuxp/cli.py

The good news is, Server() accepts a config_file: https://github.com/tmux-python/libtmux/blob/6c7c08e718a654f653e0c4388df32e048aa3e445/libtmux/server.py#L79-L94

Do you want to give this a shot @jfindlay? It may be a good first issue

Token credit: #665. The real win here though, is getting me to think about tmuxp code which increases the probability I will contribute again in the future.

If you try one of these, how's that?

And that's good with me!

I have verified the new flag works with both versions.
