I want to have Syntax Highlighting for jQuery and maybe when I type <html> it can automatically insert </html>. Is there anyway to make GEdit do this?
What the difference between jQuery syntax and JS syntax ? :)
For auto complete functionality you'll need to import jQuery snippets, just follow this guide (dead link)
For more intelligent JS coding in gedit I'll advice to use JSLint, look how to integrate it into gedit . You'll need to activate External Tools plugin.
Good luck to you with gedit and JS :) Really nice technologies.
