Icons representing active tab processes

[joncrangle]

Thanks @michaelbrusegard for creating this project.

Here's a show and tell for how I am using tabline.wez to show icons for the active tab processes in my tab bar:

Create a lua table with process names as keys and corresponding icons ref: wezterm.nerdfonts. Make sure to include a default key and value since this will be a fallback icon.

local icons = {
  ['bash'] = wezterm.nerdfonts.cod_terminal_bash,
  ['btm'] = wezterm.nerdfonts.mdi_chart_donut_variant,
  ['btop'] = wezterm.nerdfonts.md_chart_areaspline,
  ['cargo'] = wezterm.nerdfonts.dev_rust,
  ['cmd.exe'] = wezterm.nerdfonts.md_console_line,
  ['curl'] = wezterm.nerdfonts.mdi_flattr,
  ['debug'] = wezterm.nerdfonts.cod_debug,
  ['default'] = wezterm.nerdfonts.md_application,
  ['docker'] = wezterm.nerdfonts.linux_docker,
-- ... etc
}

The following function looks for a key that starts with the name returned by the process component.

local function get_icon(str)
  for k, v in pairs(icons) do
    if str:lower():match("^" .. k) then
      return v
    end
  end
  return icons['default']
end

Within your tabline.wez setup for tab_active and/or tab_inactive use the get_icon function:

        {
          'process',
          fmt = function(str)
            return get_icon(str)
          end
        },

As of #14, this is now a built in functionality 🎉
