Reload Helix automatically after switching from lazygit

This is a continuation of the Helix series. In the previous posts, I shared methods to:

I also have a script to call lazygit from within Helix:

#!/bin/sh

source wezterm-split-pane.sh

program=$(wezterm cli list | awk -v pane_id="$pane_id" '$3==pane_id { print $6 }')
if [ "$program" = "lazygit" ]; then
    wezterm cli activate-pane-direction down
else
    echo "lazygit" | wezterm cli send-text --pane-id $pane_id --no-paste
fi

Howerver, there is an issue with git gutter is not updated after committing.

To address this, I’ve come up with an automatic workaround using WezTerm’s support for custom events. I created an event to reload Helix if we are coming back from lazygit:

wezterm.on('reload-helix', function(window, pane)
  local top_process = basename(pane:get_foreground_process_name())
  if top_process == 'hx' then
    local bottom_pane = pane:tab():get_pane_direction('Down')
    if bottom_pane ~= nil then
      local bottom_process = basename(bottom_pane:get_foreground_process_name())
      if bottom_process == 'lazygit' then
        local action = wezterm.action.SendString(':reload-all\r\n')
        window:perform_action(action, pane);
      end
    end
  end
end)

then I just need to trigger multiple actions when switching panes:

config.keys = {
  {
    key = '[',
    mods = 'CMD',
    action = act.Multiple {
      act.ActivatePaneDirection 'Up',
      act.EmitEvent 'reload-helix',
    }
  },

With this solution, Helix will automatically reload when switching from lazygit, making the workflow more seamless and efficient.
