Does anyone use Aptana for WordPress plugin development? Is there a way to set-up WP code hinting with Aptana?
Yes, im and other users use Aptana always for WP Development and worls very fine. You must only include your install of WP for Dev or Stable to the project of your plugin, thats all. Now you can use all functions, vars, class ... inside your plugin of the referenced WP install.
If you start an new project; maybe an plugin, than add the externel directory or project in PHP Buildpath-tab of properties. Alternate you can change the properties via context menu, right mouse button on the project, and add the path or project in the PHP Buildpath.
for Linux Users with Ubuntu Natty
If you dont have the Command-Menu on your Linux install (if you use linux, than use this hack.
via Command Menu
You can also use the command-menu for add an bundle, also WordPress is inside via Core from Aptana Studio 3. Klick Commands --> Bundle Development --> Install Bundle --> Klick WordPress and than OK; thats all.
After this you have all functions, etc.
I don't use Aptana but the top Google result said:
Aptana 3 click Command->Bundle Development->Install Bundle -> Select bundle to install->WordPress.
