Python Docstring Inserter

This repository enables the automatic generation of function docstrings in Python according to the Google style guide. Here is an example:

def fetch_data(url: str, keys: List[int]) -> Mapping[int, str]:
    """This is a short description of this function and can span over multiple
    lines.

    This is a long description of the function with more details about it.

    Args:
        url: This is an argument description, which can span over multiple
            lines too.
        keys: This is a description of the second argument.

    Returns:
        This is a description of the returned data and can be detailed too.

    """

The text gets automatically indented and split on multiple lines.

This package is available on MELPA. You can refer to this page to learn how to use the MELPA repository.

With use-package and quelpa

(use-package python-insert-docstring
  :ensure nil
  :quelpa (python-insert-docstring
           :fetcher github
           :repo "macurovc/insert-docstring"))

Manually

Place python-insert-docstring.el in your Emacs load-path. E.g.:

(add-to-list 'load-path (expand-file-name "~/{path/to}/insert-docstring"))
(require 'python-insert-docstring)

Usage

Set in the ~/.emacs file a keybinding such as:

(defun set-python-keybindings ()
  (local-set-key (kbd "C-c i") 'python-insert-docstring-with-google-style-at-point)
  )
(add-hook 'python-mode-hook 'set-python-keybindings)

Now, in a python file, place the cursor on a function, type C-c i and follow the instructions.
