Lua script for Geany to view manpage of functions

When editing when Geany, you need some document of system library functions at hand. So you want to browse manpage at any time.

Just two lines:
[cc lang="lua"]
sel=geany.selection()
geany.launch('rxvt-unicode', '-e', 'man', sel)
[/cc] http://gist.github.com/591279

Make sure you have geany-plugin-lua installed: sudo apt-get install geany-plugin-lua

Create a lua source file named 'ShowMan.lua' in ~/.config/geany/plugins/geanylua/ . If the direcotry does not exist, you should create it first.

Copy two lines of lua code into this file, save and close.

Create a file named hotkeys.cfg in ~/.config/geany/plugins/geanylua/, add following content: ShowMan.lua

Restart geany, then open Preferences->Keybindings, Lua Script-> ShowMan, bind a key, for example, Alt+m

Select the function name, and press Alt+m (or from menu Tools->Lua Scripts->ShowMan), then you see the terminal and the manpage.
