Provides a default regex validator 16 | - Validates against list of [banned 17 | words](https://github.com/theskumar/python-usernames/blob/master/usernames/reserved_words.py) 18 | that should not be used as username. 19 | -

`whitelist`: a case insensitive list of words that should be 40 | considered as always safe. Default: `[]` 41 | - `blacklist`: a case insensitive list of words that should be 42 | considered as unsafe. Default: `[]` 43 | - `max_length`: specify the maximun character a username can have. 44 | Default: `None` 45 | 46 | - `regex`: regular expression string that must pass before the banned 47 | : words is checked. 48 | 49 | The default regular expression is as follows: 50 | 51 | ^ # beginning of string 52 | (?!_$) # no only _ 53 | (?![-.]) # no - or . at the beginning 54 | (?!.*[_.-]{2}) # no __ or _. or ._ or .. or -- inside 55 | [a-zA-Z0-9_.-]+ # allowed characters, atleast one must be present 56 | (?= 3.8" 11 | dynamic = ["version"] 12 | 13 | keywords = [ 14 | 'security', 15 | 'username', 16 | 'validation', 17 | 'user registration', 18 | 'safe', 19 | 'signup', 20 | 'regex', 21 | ] 22 | 23 | classifiers=[ 24 | # As from https://pypi.org/classifiers/ 25 | # 'Development Status :: 1 -
