Python scripts

Scripts in $XDGCONFIGHOME/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!')
