Automatic style guide and docstrings generator for Python code
Project description
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
