if callback is None:

numberoverzero / color.py
Last active December 16, 2015 20:19
Swizzle-able color attribute access. Part of the gritty module rewrite.
import re
import collections
CHANNELS = 'rgba'
DEFAULT_COLORS = [0, 0, 0, 255]
CHANNEL_SEARCH = re.compile('[^' + CHANNELS + ']').search
IS_MULTI_CHANNEL = lambda name: name and not bool(CHANNEL_SEARCH(name))

numberoverzero / factory.py
Created May 19, 2013 19:49
factory that captures the usual args, kwargs of instantiation and saves them so multiple copies can be created.
from functools import wraps
class Factory(object):
def __init__(self, cls, *args, **kwargs):
self._cls = cls
self._args = args
self._kwargs = kwargs
@property
def instance(self):
return self._cls(*(self._args), **(self._kwargs))

numberoverzero / profanity.py
Created March 26, 2014 22:34
Filter delimited profanity - does not handle character substitution
'''
Character substitution
====
Not handled at all. Should be reasonably straightforward to plug into the existing code.
Roughly:
def expand_substitutions(wordlist, sub_map):
for word in wordlist:
for substitution in expand_word(word, sub_map):
yield substitution
