How to replace url with link to that url in post with Flask?

Question

How can I use Python and Flask to insert a link in a post if there is one.

For example if someone puts "google.com" in their post how can I then make that a link?

If you are using jinja2 as your templating system, you can use the built in urlize filter which will convert all urls in some text to html link tags:

{{ mytext|urlize(40, true) }}
links are shortened to 40 chars and defined with rel="nofollow"

It has numerous useful options you can read about in the docs:

If you are using some other templating engine, they probably have something similar.

If you want to do it client side there is a good discussion of all your options here:

Is there a way to do something like this to tag Users with @? – Jacob Bennett Apr 18 '15 at 22:15
It's probably pretty easy to do a match on @something in a string. What do you want the link to look like? A link to Twitter? Just write a filter. – Robert Moskal Apr 19 '15 at 00:15
As you can probably tell, I'm pretty new to this stuff. How would I go about writing a filter? Thank You for the help! – Jacob Bennett Apr 19 '15 at 18:16
I suppose you could ask a new question. But you could also look at the docs. It's pretty easy.http://flask.pocoo.org/docs/0.10/templating/ – Robert Moskal Apr 19 '15 at 18:21
