Ask your question!

I am trying to make WezTerm behave similar to other application on MacOS where Command-comma opens preferences/settings. So far I have figured out how to have WezTerm open a new window with vim to edit the configuration, but I would like to use a different external/non-terminal application (accessed via an edit command).

Without a keybinding the command I am trying to run is edit ~/.wezterm.lua

This is what I have to get the keybinding working in vim, what would it take to make this work with edit instead (just changing vim to edit in the args doesn't work):

{
  key = ',',
  mods = 'SUPER',
  action = act.SpawnCommandInNewWindow({
    cwd = os.getenv('WEZTERM_CONFIG_DIR'),
    args = {
      os.getenv('SHELL'),
      '-c',
      'vim $WEZTERM_CONFIG_FILE',
    },
  }),
}

Simply use background_child_process in a custom action.

https://wezterm.org/config/lua/wezterm/background_child_process.html?h=back

local wezterm = require 'wezterm'

return {
  keys = {
    {
      mods = 'CTRL|SHIFT',
      key = 'm',
      action = wezterm.action_callback(function(win, pane)
        wezterm.background_child_process {
          'edit',
          '~/.wezterm.lua'
        }
      end),
    },
  },
}

Edit for inclusion into your config.
