Reload Helix automatically after switching from lazygit

2023-07-25

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:

 1#!/bin/sh
 2
 3source wezterm-split-pane.sh
 4
 5program=$(wezterm cli list | awk -v pane_id="$pane_id" '$3==pane_id { print $6 }')
 6if [ "$program" = "lazygit" ]; then
 7    wezterm cli activate-pane-direction down
 8else
 9    echo "lazygit" | wezterm cli send-text --pane-id $pane_id --no-paste
10fi

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:

 1wezterm.on('reload-helix', function(window, pane)
 2  local top_process = basename(pane:get_foreground_process_name())
 3  if top_process == 'hx' then
 4    local bottom_pane = pane:tab():get_pane_direction('Down')
 5    if bottom_pane ~= nil then
 6      local bottom_process = basename(bottom_pane:get_foreground_process_name())
 7      if bottom_process == 'lazygit' then
 8        local action = wezterm.action.SendString(':reload-all\r\n')
 9        window:perform_action(action, pane);
10      end
11    end
12  end
13end)

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

1config.keys = {
2  {
3    key = '[',
4    mods = 'CMD',
5    action = act.Multiple {
6      act.ActivatePaneDirection 'Up',
7      act.EmitEvent 'reload-helix',
8    }
9  },

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