Rfcparser

Rfcparser is a Python tool that makes it easy to parse common RFC syntaxes. Rfcparser takes a raw string as input, parses, validates, and returns Python objects to simplify the processing of RFC syntaxes.

Installing

$ pip install rfcparser

or

$ git clone https://github.com/karosis88/rfcparser.git
$ pip install ./rfcparser

Usage

Examples and detailed instructions on how to use the Rfcparser library to parse RFC syntaxes.

In most cases, you will primarily use the 'core' module, which offers a convenient interface for parsing your raw input string

>>> from rfcparser import core

Rfcparser offers a specific class for each grammar, with a class name following the pattern of "PREFIX PARSER RFC-NUMBER"

Fortunately, most modern IDEs now offer autocompletion, which will assist you in locating the parser classes you need to use.

URI parsing

>>> uri = "https://login:password@127.0.0.1:1010/path?name=test#fr"
>>> parsed_uri = core.UriParser3986().parse(uri)

With Rfcparser, you now have access to a 'parsed_uri' that is not just a plain string, but rather a Python object. This makes it easier to work with the URI, and you don't need to worry about compatibility issues with other applications as the library parses syntaxes according to the latest RFC standards.

>>> parsed_uri.scheme
'https'
>>> parsed_uri.userinfo
'login:password'
>>> parsed_uri.ip
'127.0.0.1'
>>> parsed_uri.port
1010
>>> parsed_uri.path
'/path'
>>> parsed_uri.query
{'name': 'test'}
>>> parsed_uri.fragment
'fr'

Date-Time parser

>>> date_str = "Tue, 07-Feb-2023 13:20:04 GMT"
>>> parsed_date = core.DateParser6265().parse(date_str)
>>> type(parsed_date)
<class 'datetime.datetime'>
>>> parsed_date.day
