Zeal is an offline documentation browser which can be used to lookup help for most popular libraries and APIs. The ZealLookup plugin (also called ZealEclipsePlugin) enables you to lookup help in Zeal right from inside Eclipse! 😊
Download the plugin
.jar file from here and place it in the
plugins directory of your Eclipse installation.
You need to configure a keyboard shortcut for ZealLookup. Go to Window -> Preferences -> General -> Keys. Look for Lookup in Zeal command and set a keyboard shortcut for it.
To lookup a word in Zeal: highlight the word and press the keyboard shortcut you have set earlier. Zeal should open with the documentation for the word. I found that sometimes Zeal stays in the background, but it has looked up the word.
For use with Vrapper, I mark the current word using
viw (visually mark inner word) and then press the ZealLookup keyboard shortcut.
Tried with: ZealLookup 1.0.0, Eclipse 4.4.2 and Ubuntu 14.04
