Today I needed a function to create a slug (an ASCII-only representation of a string). I went
|
||
Googling a bit, and found an excellend `Flask snippet <http://flask.pocoo.org/snippets/5/>`_.
|
||
Problem is, it is designed for Python 2, so I came up with a Python 3 version.
|
||
|
||
.. code-block:: python
|
||
|
||
import re
|
||
from unicodedata import normalize
|
||
|
||
_punctuation_re = re.compile(r'[\t !"#$%&\'()*\-/<=>?@\[\\\]^_`{|},.]+')
|
||
|
||
def slugify(text, delim='-'):
|
||
"""
|
||
Generate an ASCII-only slug.
|
||
"""
|
||
|
||
result = []
|
||
for word in _punctuation_re.split(text.lower()):
|
||
word = normalize('NFKD', word) \
|
||
.encode('ascii', 'ignore') \
|
||
.decode('utf-8')
|
||
|
||
if word:
|
||
result.append(word)
|
||
|
||
return delim.join(result)
|
||
|
||
As I don’t really like the transliteration done in the first example (e.g. converting ü to ue), I
|
||
went with the second example.
