# Nice Regular Expressions

A simple wrapper around the `re` module that supports multiple patterns, and reuse of patterns.

## Installation

    pip install nre

   

## Usage

    import nre

    patterns = nre.from_string(r'''

    number=\d+

    decimal={{number}}\.{{number}}

    lowercase=[a-z]+

    ''')

    print(patterns.decimal.findall("123.22")) # returns ['123.22']

    print(patterns.number.findall("123.22")) # returns ['123', '22']

    print(patterns.decimal.findall("abc"))  # returns []

    print(patterns.lowercase.findall("abc"))  # returns ['abc']

    

 We recommend using external pattern files

 

     import nre

     patterns = nre.from_file("patterns.nre")

 

 If you use external files, you can import them within other files

 

    # contents of users.nre

    valid_username=[a-zA-z_]+

    

    # contents of emails.nre

    import users

    valid_email={{valid_username}}@gmail.com
