regex-cleaner 1.0.2

A small package to convert verbose regex patterns to simple regex patterns.

Regex Cleaner

This is a simple python package that can be used to clean a verbose regex pattern of the comments and new lines and return the basic underlying pattern.

Installation

python -m pip install regex-cleaner

Usage

To clean a regex pattern, simply pass the verbose pattern string to the function clean_regex.

from regex_cleaner import clean_regex

pattern = r"""
    \w\d{3} # Matches any letter followed by 3 digits.
"""
cleaned_regex = clean_regex(pattern)

print(cleaned_regex)

\w\d{3}

It should be noted that the pattern is cleaned by removing all comments from the string, then removing any whitespace left in the pattern. This means that if you are using whitespace to represent space characters in your pattern they will be trimmed out.

import regex_cleaner

pattern = r"""
    \w* # Any letter repeated zero or more times.
    [. ] # Full stop followed by a space.
"""

cleaned_pattern = regex_cleaner.clean_regex(pattern)

print(cleaned_pattern)

\w*[.]
