The [luahelp script] is in the "insecure area" of this Wiki.

I use Lua only episodically, and I hate having to look up API functions every time I want to do something. If only there were man pages, I could just type man lua_gettable and everything would be good. But there are no man pages :-(

Do not fear! An hour of hacking solves the problem. Attached is a script that goes through the HTML version of the Lua manual and extracts documentation relevant to functions by name (and more besides). Some examples you can try include

  luahelp
  luahelp gettable
  luahelp expressions
  luahelp metatable

and much more besides. For guidance, run the script with no arguments.

Be warned that you will need to edit two variables! The script needs to know where the manual is, and it needs a pager that can display HTML read from standard input. The defaults should work on Debian linux, provided you have lynx installed.
