Question

Think twitter where you paste a link next to some plain text and when your tweet is rendered, that url is now a clickable link.

Do I:

• replace jinja’s autoescape with my own by scanning the text for html tags and replacing them with the html entity code

• use a regular expression to detect a url contained in the text and replace it within an a href=

  • what would this expression look like to detect any # of .tld’s, http/https, www/any subdomain?

• and render this all as ¦safe in the template?

Or is there a python/flask/jinja ‘feature’ that can better handle this kind of thing?

Answer 1

Jinja has a filter built-in called urlize that should do exactly what you want.
