What's the open source code editor with the best code completion for HTML, CSS and JS?

Question

What's the open source code editor with the best code competion for HTML, CSS and JS? (such as Dreamweaver and MS Expression Web or Visual Web Developer). Because I really find it annoying to have to download the whole framework of Adobe and MS products as they are 200MB+. Notepad++ is nice but its Auto-completion isn't as advanced as DW or EW.

Answer 1

You can do something like this and of course there's always eclipse with whichever plugins you need.

Answer 2

I like Eclipse (http://www.eclipse.org/webtools/development/)
