Map commands to Python functions feature.

[rajaravivarma-r]

I wanted a way to call Python functions through vim commands, and I have wrote one helper function in my .vimrc.py,

def command_map(command, nargs="*"):
    def decorator(func):
        def wrapper(*args):
            args = snake.vim.eval("a:000")
            return func(*args)

        wrapper_func = snake.register_fn(wrapper)
        function_name = f"Snake_{func.__name__}"
        snake.command(
            f"""
            function! {function_name}(...)
                :{snake.PYTHON_CMD} {wrapper_func}
            endfunction
            """
        )
        snake.command(
            f"command! -nargs={nargs} {command} call {function_name}(<f-args>)"
        )
        return wrapper

    return decorator


@command_map("Pwf")
def copy_current_file_path(*args, **kwargs):
    current_buffer = snake.vim.current.buffer
    if current_buffer.name is None:
        snake_echo("No file loaded in current buffer")
    else:
        pyperclip.copy(current_buffer.name)
        snake_echo(current_buffer.name)

Do you think this feature could get into the core? I would like to contribute with a PR if you wish.
