Predefined slugify functions

Some slugify functions is predefined this way:

from slugify import Slugify, CYRILLIC, GERMAN, GREEK

slugify = Slugify()
slugify_unicode = Slugify(translate=None)

slugify_url = Slugify()
slugify_url.to_lower = True
slugify_url.stop_words = ('a', 'an', 'the')
slugify_url.max_length = 200

slugify_filename = Slugify()
slugify_filename.separator = '_'
slugify_filename.safe_chars = '-.'
slugify_filename.max_length = 255

slugify_ru = Slugify(pretranslate=CYRILLIC)
slugify_de = Slugify(pretranslate=GERMAN)
slugify_el = Slugify(pretranslate=GREEK)

Examples

from slugify import Slugify, UniqueSlugify, slugify, slugify_unicode
from slugify import slugify_url, slugify_filename
from slugify import slugify_ru, slugify_de

slugify('one kožušček')                       # one-kozuscek
slugify('one two three', separator='.')       # one.two.three
slugify('one two three four', max_length=12)  # one-two-four   (12 chars)
slugify('one TWO', to_lower=True)             # one-two
slugify('one TWO', capitalize=True)           # One-TWO

slugify_filename(u'Дrаft №2.txt')             # Draft_2.txt
slugify_url(u'Дrаft №2.txt')                  # draft-2-txt

my_slugify = Slugify()
my_slugify.separator = '.'
my_slugify.pretranslate = {'я': 'i', '♥': 'love'}
my_slugify('Я ♥ борщ')                        # I.love.borshch  (custom translate)

slugify('Я ♥ борщ')                           # Ia-borshch  (standard translation)
slugify_ru('Я ♥ борщ')                        # Ya-borsch   (alternative russian translation)
slugify_unicode('Я ♥ борщ')                   # Я-борщ      (sanitize only)

slugify_de('ÜBER Über slugify')               # UEBER-Ueber-slugify

slugify_unique = UniqueSlugify(separator='_')
slugify_unique('one TWO')                     # One_TWO
slugify_unique('one TWO')                     # One_TWO_1

slugify_unique = UniqueSlugify(uids=['cellar-door'])
slugify_unique('cellar door')                 # cellar-door-1

Custom Unique Slugify Checker

from slugify import UniqueSlugify

def my_unique_check(text, uids):
    if text in uids:
        return False
    return not SomeDBClass.objects.filter(slug_field=text).exists()

custom_slugify_unique = UniqueSlugify(unique_check=my_unique_check)

# Checks the database for a matching document
custom_slugify_unique('te occidere possunt')
