Improved version of my snippet #1346. Now works correctly with multiple usernames and hash tags.
Both twitter usernames and hashtags are converted into links to twitter profiles and twitter search.
Updated, forgot about underscores in usernames.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | import re
from django.utils.safestring import mark_safe
from django import template
register = template.Library()
@register.filter(name='twitterfy')
def twitterfy(tweet):
# find hashtags
pattern = re.compile(r"(?P<start>.?)#(?P<hashtag>[A-Za-z0-9_]+)(?P<end>.?)")
# replace with link to search
link = r'\g<start>#<a href="http://search.twitter.com/search?q=\g<hashtag>" title="#\g<hashtag> search Twitter">\g<hashtag></a>\g<end>'
text = pattern.sub(link,tweet)
# find usernames
pattern = re.compile(r"(?P<start>.?)@(?P<user>[A-Za-z0-9_]+)(?P<end>.?)")
# replace with link to profile
link = r'\g<start>@<a href="http://twitter.com/\g<user>" title="#\g<user> on Twitter">\g<user></a>\g<end>'
text = pattern.sub(link,text)
return mark_safe(text)
