Search the regex that fits all querying strings.

Project description

PyPI version PyPI pyversions PyPI license

Search the regex that fits all querying strings.

  • Dozens of pre-written regexes are indexed and organized as a partial order, available in regexorder/templates.json.

  • The regex of all the querying string's least upper bound in the partial order is returned.

  • templates.svg plots the partial order.


The core part is the pre-written regexes and their respective structure. Currently they only cover the most common cases.

  • Any idea or contribution is highly welcome.

Our regexes utilize some advanced Unicode features, that are not available in standard re library yet. Thus, the more advanced regex library must be used to match our regexes.


This package is available on PyPI. Just use pip3 install -U RegexOrder to install it.


from regexorder import RegexOrder

r = RegexOrder()

t = r.match("123")
# 'positive_integer'
# '\\+?\\d+'

t = r.matchall(["apple", "banana", "cheese cake"])
# 'multiple_lowercase_words'
# '\\p{Ll}+(\\s+\\p{Ll}+)*'
