Yesterday I came across a blog post by Richard Hult. He imported something called “assistant” into Devhelp in trunk. This assistant is a small window displaying documentation for one function, class/object or macro. He also wrote some code so Emacs would automatically update this window while the user is typing/coding. I thought it would be nice to have this for VIM, so I hacked on a small plugin for it. You can see a demo here. I haven’t uploaded the source code yet, but it’ll either end up in Devhelp or on vim.org as soon as it is finished.
Edit: After some positive feedback, I have now filed a feature request for the plugin to be added to devhelp. If you’re interested in testing, go grab it from there. Please let me know about your ideas or bugs you have found.
Edit: The code has been imported into devhelp trunk.
