Monkey patch regular expressions

Project description

# GoRella [![Build Status](https://travis-ci.org/frostming/gorella.svg?branch=master)](https://travis-ci.org/frostming/gorella)

Monkey patch regular expression methods to built-in string types

## Introduction This project is aiming at easing the use of regular expression, which is inspired by RegExp in JavaScript. The name comes from “gorilla” and “re”. The sing-file module will monkey patch the following built-in methods of string types on its import:

  • replace
  • split and rsplit
  • find and rfind
  • index and rindex
  • partition and rpartition
  • count
  • startswith and endswith

Besides, it extends the built-in string types with following methods of re module:

  • match
  • search
  • findall
  • finditer

## Usage All you need is to import gorella in one line, everything is done for you: `python >>> import gorella >>> 'I am 26 years old.'.search('\d+').group() '26' ` For built-in methods, when pass a regular expression object, it will call the corresponding re function, else it falls back to built-in one: `python >>> pat = re.compile('\d+') >>> 'I am 26 years old.'.find('am') 2 >>> 'I am 26 years old.'.find(pat) 5 >>> 'I am 26 years old.'.partition(pat) ('I am ', '26', ' years old') ` Because it replaces the pure-C methods with python ones, the performance may be affected.

## Python 3 support The monkey patching highly depends on the C-API of CPython, so it doesn’t support other implementations than CPython. The test passes on Python 2.6, 2.7, 3.3, 3.4 and 3.5
