textwrapre 0.10

Splits large texts into smaller ones that can't exceed a certain limit, but need to be split where a certain regular expression matches

textwrapre

A Python package to split text into smaller blocks based on regular expressions.

It's useful to split large texts into smaller ones that can't exceed a certain limit,

but need to be split where a certain regular expression matches.

pip install textwrapre

Usage

from textwrapre import wrapre

import regex



text = r"""

Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch 

Centrum (CWI, see https://www.cwi.nl/) in the Netherlands as a successor of a 

language called ABC. Guido remains Python’s principal author, although it includes

many contributions from others.



In 1995, Guido continued his work on Python at the Corporation for 

National Research Initiatives 

(CNRI, see https://www.cnri.reston.va.us/) in Reston, 

Virginia where he released several versions of the software.
