pardoc 0.1.1

pardoc

Yet another docstring parser for python, using lark-parser
Installation
pip install pardoc

A quick look
>>> from pardoc import google_parser, pretty

>>> docstring = """This is an example of a module level function.

Function parameters should be documented in the ``Args`` section. The name
of each parameter is required. The type and description of each parameter
is optional, but should be included if not obvious.

If \*args or \*\*kwargs are accepted,
they should be listed as ``*args`` and ``**kwargs``.

The format for a parameter is::

name (type): description
The description may span multiple lines. Following
lines should be indented. The "(type)" is optional.

Multiple paragraphs are supported in parameter
descriptions.

Args:
param1 (int): The first parameter.
param2 (:obj:`str`, optional): The second parameter. Defaults to None.
Second line of description should be indented.
*args: Variable length argument list.
**kwargs: Arbitrary keyword arguments.

Returns:
bool: True if successful, False otherwise.

The return type is optional and may be specified at the beginning of
the ``Returns`` section followed by a colon.

The ``Returns`` section may span multiple lines and paragraphs.
Following lines should be indented to match the first line.

The ``Returns`` section supports any reStructuredText formatting,
including literal blocks::

{
'param1': param1,
'param2': param2
}

Raises:
AttributeError: The ``Raises`` section is a list of all exceptions
that are relevant to the interface.
ValueError: If `param2` is equal to `param1`.

Usage
Parsing a known style docstring
from pardoc import google_parser, numpy_parser
parsed = google_parser(docstring)
# or
parsed = numpy_parser(docstring)

Parsing an unknown style docstring
from pardoc import auto_parser

parser = auto_parser(docstring)
# parsing results from auto_parser is cached and reused.
parsed = parser.parse(docstring)

Parsed object
There are 6 types of parsed objects, include the final Parsed object that
attaches all sections
The first 5 are all namedtuples:
ParsedItem = namedtuple('ParsedItem',
['name', 'type', 'desc', 'more'])
ParsedTodo = namedtuple('ParsedTodo', ['todo', 'more'])
ParsedSection = namedtuple('ParsedSection', ['title', 'section'])
ParsedPara = namedtuple('ParsedPara', ['lines'])
ParsedCode = namedtuple('ParsedCode', ['lang', 'codes'])

The Parsed is an ordered dictionary (OrderedDiot) from diot, which
allows dot access to keys:
from diot import OrderedDiot

class Parsed(OrderedDiot):
"""Parsed object"""

Formatting a parsed object to the original style
>>> from pardoc import google_parser
>>> docstring = """Example function with types documented in the docstring.

Args:

param0: No type

param1 (int): The first parameter.
param2 (str): The second parameter.

Returns:

bool: The return value. True for success, False otherwise.

"""
>>> # note the arbitrary empty lines
>>> reformatted = google_parser.format(docstring)
>>> # or
>>> reformatted = google_parser.format(google_parser.parse(docstring))
>>> print(reformatted)
Example function with types documented in the docstring.

Args:
param0: No type
param1 (int): The first parameter.
param2 (str): The second parameter.

Returns:
bool: The return value. True for success, False otherwise.
