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.
