There is also jquery-textcomplete: https://github.com/yuku-t/jquery-textcomplete

A slightly offtopic question: can anybody point me to a js lib, which converted tabs pressed when inside a textarea into spaces and indented the text below accordingly?

http://jakiestfu.github.io/Behave.js/ is a bit more of a lightweight option than a full code editor.

This is great, I've been looking for something like this. Thanks!

http://ace.c9.io/ is probably what you're looking for.

Ace Editor is pretty comfigurable and allows for this as well as syntax highlighting for, say, markdown.

Very clean implementation. I have a feeling I'll be needing this soon.

Seems broken, hitting enter a few time shows text outside of the box.

Same for me on Chrome... It seems to either be missing the auto resize part. Or some CSS.

The textarea just needs the `overflow: scroll` or `overflow: auto` CSS property.

wow. cool. I will fix it soon.

Looks really nice, just today I was working on a new input for our comments and this seems to fit really well. Will give it a try!

Great job with this. We had created a similar plugin called bootstrap-tagautocomplete: https://github.com/Sandglaz/bootstrap-tagautocomplete

Awesome! I really needed something like that. The implementation looks great too. Thanks! I started doing my own a while back but it only supported @mentions.

Can you share the link for that? Thanks.

I've been looking for something like this to use in my webIRC application. Can't wait to give this a try.

great job! following!
