Automatic style guide and docstrings generator for Python code

alphadoc

Automatic docstring generator and style guide that supports a number of specified conventions for documentation in Python.

Features

• Auto-generates docstrings with a customizable template for functions.
• Automatically fixes the code according to the standard PEP-8 style convention for python.
• Support for common and widely used docstrings formats such as Numpy, Google, ReStructured Text and Epytext (Javadoc)

Installation

Using pip:

$ pip install alphadoc

Usage

alphadoc takes your filename and format type as arguments

$ alphadoc <filename> --d <doc_format>

See alphadoc --help for more command-line switches and options!

Options :

Usage: alphadoc [OPTIONS] FILENAME

  Automatic docstring generator and style guide that  supports a
  number of specified conventions for formatting  as well as
  documentation in Python.

Options:
  -d, --doc_format TEXT  Specified format for docstrings from Options-
                         ReST : For ReStructured Text (default); Epytext
                         :  For Epytext (Javadoc); Google : For Google-
                         Style ; Numpydoc : For Numpydoc

  --help                 Show this message and exit.

Example :

Before alphadoc

import ast
import sys

def top_level_functions(body):
    return (f for f in body if isinstance(f, ast.FunctionDef))

def parse_ast(filename):
    with open(filename, "rt") as file:
        return ast.parse(file.read(), filename=filename)

def get_func(filename):
    tree = parse_ast(filename)
    func_list = []
    for func in top_level_functions(tree.body):
        func_list.append(func.name)
    return func_list

After alphadoc

Docstring format:

• ReStructured Text (default)
