• Snacks Zen Mode Font Size with Ghostty on macOS

  If you use LazyVim with Ghostty on macOS, you might have noticed that Zen mode doesn’t support changing font size (unlike Kitty or WezTerm which have official plugins).

  However, we can work around it using AppleScript to simulate keyboard shortcuts. Add this to your ~/.config/nvim/lua/plugins/snacks.nvim config:

  {
    "folke/snacks.nvim",
    opts = {
      zen = {
        on_open = function()
          vim.fn.system("osascript -e 'tell application \"Ghostty\" to activate' -e 'tell application \"System Events\" to keystroke \"+\" using command down'")
        end,
        on_close = function()
          vim.fn.system("osascript -e 'tell application \"Ghostty\" to activate' -e 'tell application \"System Events\" to keystroke \"0\" using command down'")
        end,
      },
    },
  }
  

  This simulates Cmd++ when entering zen mode and Cmd+0 to reset on exit. You’ll need to grant Accessibility permissions for Ghostty when prompted or in System Settings → Privacy & Security → Accessibility.

• Lazygit + Delta macOS System Appearance Tip

  I want to share a quick tip for configuring Lazygit to respect macOS system appearance when using Lazygit with Delta custom pager.

  In your Lazygit config file (by default at ~/Library/Application Support/lazygit/config.yml), configure Delta pager as follows:

  git:
    pagers:
      - pager: delta --paging=never $(defaults read -g AppleInterfaceStyle 2>/dev/null | grep -q "Dark" && echo "--dark" || echo "--light")
  

  This command checks macOS’s current appearance mode and automatically passes the appropriate --dark or --light flag to Delta. The theme will update dynamically whenever you switch between light and dark mode.
