tmux.fish ❐ 🐟

Note

There are breaking changes before v2 which is basically a complete rewrite. This plugin was not one to one port of ohmyzsh tmux plugin before v2. After v2 (including this main branch) this plugin works and behaves exactly like the zsh plugin. See this for more information.

This is a tmux plugin for fish. It is port of ohmyzsh tmux plugin but for Fish shell.

Features

This plugin does the following:

• determines if tmux is installed or not, if not, prompt user to install tmux
• determines if the terminal supports the 256 colors or not, sets the appropriate configuration variable
• sets the correct local config file to use

Installation

First, make sure you have the recent version of tmux and fish as I don't test this on older version. Next, install this plugin with Fisher:

fisher install budimanjojo/tmux.fish

Configuration

You can modify the default configuration variables either by exporting the env from your config.fish or in your terminal. To autostart tmux when you open your terminal, you can put something like this in your config.fish:

status is-interactive; and begin
    set fish_tmux_autostart true
end

Remember to order the set command after $PATH is set correctly for tmux command so the plugin can find it.

Difference with ZSH Version

• Added fish_tmux_no_alias variable to disable creating aliases except for tmux alias because it is the core of this plugin.
• Autostart is a fish function with --on-variable option. This means the autostart will run as soon as you change the variable $fish_tmux_autostart to true. This lets you decide when to start the function. This is needed due to how fish handle the order of execution. Fish will always load everything inside $__fish_config_dir/conf.d before running user config. This leads to issue such as tmux not found.
• Most configuration variables are local to the function when being run. So your current shell won't be filled with fish_tmux_xxx variables.
