    cd auto_regex
    python setup.py install

or just bundle the python file with your project, it is standalone

usage

importing the module

from autoregex import AutoRegex

a = AutoRegex()

generating a regex expression

texts = ["say {word}", "repeat {word}"]
for regex_expression in a.get_expressions(texts):
  print(regex_expression)

outputs

^\W*say\W*(?P<word>.*?\w.*?)\W*$
^\W*repeat\W*(?P<word>.*?\w.*?)\W*$

extracting entities from regex

  lines= ["say {word}", "repeat {word}"]
  query = "say hello"
  a.create_regex(lines)
  for ent in a.get_entities(query):
      print(ent)

outputs

  {'word': 'hello'}

matching regexes

  lines= ["say {word}", "repeat {word}"]
  query = "say i am a bot, blip blop"
  a.create_regex(lines)
      for e in a.get_matches(query):
          print(e)

outputs

  {
    'query': 'say i am a bot, blip blop', 
    'entities': {'word': 'i am a bot, blip blop'}, 
    'regexes': ['^\\W*repeat\\W*(?P<word>.*?\\w.*?)\\W*$']
  }

while there is no documentation take a look at the unittests to have an idea of expected behaviour and use cases

Caveats and known bugs

• extra spaces will be removed

• spaces in entities will be replaced with _

  say {two words} -> say {two_words}

• sentences become lower case
