Wezterm + cosmic-comp "window swallowing"

swallow.md

What

Hide wezterm window while some (usually gui) app runs and show after that.

Reqs

• Wezterm (well, duh)
• A window manager that processes minimization requests (probably). Works in cosmic-comp ootb, doesn't work in qtile (can probably be done with some configuration, tho)

Wezterm config

  wezterm.on('user-var-changed', function(window, pane, name, value)
    -- to see the logs use wezterm blocking-start
    -- to set a var use 
    -- ` bash -c "printf '\\033]1337;SetUserVar=$(basename "name")=$(echo value | base64)\\007'; sleep 0.1" `
    wezterm.log_info('var', name, value)

    -- "window swallowing"
    if name == 'whide' then
      window:perform_action(
        wezterm.action.Hide,
        pane
      )
    elseif name == 'wshow' then
      wezterm.log_info("here")
      window:maximize()
      window:restore()
      -- some unsuccessful (as in they don't restore the window) attempts. May work in other wm-s/de-s, tho.
      --window:perform_action(
      --  -- wezterm.action.Show,
      --  wezterm.action.SetWindowLevel 'AlwaysOnTop',
      --  pane
      --)
    end
  end)

Shell aliases

In case of fish, I made the following functions:

• setUserVar:

    function setUserVar
        bash -c "printf '\\033]1337;SetUserVar=$(basename $argv[1])=$(echo $argv[2] | base64)\\007'; sleep 0.1"
    end

• swallow:

    function swallow
      setUserVar whide
      eval $argv
      # save the exit status to be returned later
      # since neither does setUserVar fail like ever,
      # nor we need its exit code
      set -l res $status
      setUserVar wshow
      return $res
    end
