How to use tmux with custom a tmux.conf file location when using tmuxp?

[paulmsmith]

How can I run tmux with a custom config file location via tmuxp?

Why? There are usecases for running tmux with a nonstandard tmux config file or for simply wanting/needing to store the tmux config file is just in a different location than default.

Typically it is located at: ~/.tmux.conf but you might want to store it in ~/dotfiles/tmux.conf instead. To do this you use the tmux -f [path-to-conf-file] but it wasn't immediately obvious how to do this with tmuxp.

Turns out it has been possible since early 2021 with a pass through flag when using tmuxp for example:

tmuxp load ~/projects/project-a -f ~/dotfiles/tmux.conf
