Text Parsing Function Dispatcher

Project description

https://travis-ci.org/erinxocon/tpfd.svg?branch=master https://img.shields.io/pypi/v/tpfd.svg?maxAge=2592000 https://img.shields.io/pypi/l/tpfd.svg?maxAge=2592000

TPFD is an easy way to parse strings and execute functions depending on their contents.

Inspired by Flask and using Parse under the hood, this allows you to decorate functions with grammar rules and if a pattern that matches one of your grammar rules is found, the function will be run with a set of keyword arguments you’ve specified passed to it! Great for parsing logs and executing macros on what it finds!

Examples

Aniamls.txt
Turtles are cool
Sloths are cool
Mosquitos are dumb

>>> p  = tpfd.Parser()

>>> @p.on_parse('{Animal} are cool')
    def main(animal):
        print('I like {0}.'.format(animal))

>>> p.parse_file('animals.txt')
'I like turtles.'
'I like sloths.'

>>> p.parse(['Turtles are cool', 'Sloths are cool', 'Mosquitos are dumb'])
'I like turtles.'
'I like sloths.'

>>> p.parse('Sloths are cool')
'I like sloths.'

>>> p.parse('Mosquitos are dumb')
None

>>> @p.on_find('>{}<')
    def find_example(words):
    print (words)

>>> p.find('<p>the <b>bold</b> text</p>')
'the bold text'

To Install

$ pip install tpfd

Notes

Any format spec supported by parse is supported by this library since it’s all parse under the hood. Example: {[field name]:[format spec]}

Current Features

  • Support for parsing text files
  • Support for accepting generators that output text or ints
  • Support for parsing unicode strings
  • Supports parsing strings, ints and interator/generator’s automagically with new parse method.

TODO

  • Expose custom types functionality that Parse already offers
