Python scripts

Scripts in $XDG_CONFIG_HOME/nvim_pygtk3/*.py are exec'd at startup, exposing the following globals:

• connect: Utility wrapper to connect GObject signals.
• window: The GTK top-level window. Docs
  • window.terminal: The VTE terminal that hosts neovim. Docs
  • window.switcher: The GtkStackSwitcher that displays buffers. Docs
  • window.notebook: The GtkNotebook that displays tabs. Docs
  • window.viewport: The GtkViewport that holds the terminal. Docs

The window object has the following additional signals:

• nvim-setup: Emitted when neovim has started.
• nvim-notify: Emitted when neovim has notified the GUI.
• nvim-request: Emitted when neovim has requested the GUI.

Example script ~/.config/nvim_pygtk3/a.py:

@connect(window, 'nvim-setup')
def a(nvim):
    nvim.command(f'call rpcnotify({nvim.channel_id}, "hello", "world")')

@connect(window, 'nvim-notify')
def b(nvim, event, args):
    if event == 'hello':
        print('hello', args)

@connect(window.terminal, 'cursor-moved')
def c():
    print('cursor moved!')
