how to get an excerpt from a link

[sasogeek]

I want to do something similar to how facebook reatcs to links...

let's say a user makes a post with a link in it (the post is not necessarily just the link)

i want to be able to grab the link from the post, make it clickable, as well as a little excerpt from the contents in the page that link is anchored to.

eg.

blabla bla blablalbal bla blalba blalba crap! this is a link http://domain.com/somepage.html is a cool blog page.

when a user posts the above example, i want to make http://domain.com/somepage.html into an actual link which is clickable, as well as show some sort of excerpt from the contents in that page... i used fb as an example so it's easy to understand what i want to accomplish :)

help?

It depends. In which format is the input? markmin, html?

[sasogeek]

Not sure if I understand your question but I guess I'll say html cos that's what I'm familiar with... :|

{{form gluon.contrib.autolinks import expand_html}}

{{=XML(expand_html(your_html),cache.ram('mycachekey',lambda:dict(),3600)}}

will do what you ask. Will expand all links not already tagged using the oembed protocol.

Yes. I forgot.

Assuming you are running web2py from source you need to...

easy_install beautifulsoup

[sasogeek]

Is installing beautiful soup all I need to do? cos I still get the same error after installing it...

Are you running web2py from source or using one of the binaries (the binaries include their own Python interpreter, so libraries installed in your local Python installation will not be available to web2py)?
