Message:	[quote=David Haley] Right, what Twisol said. See also: http://www.lua.org/manual/5.1/manual.html#pdf-package.path I suppose it's possible that package.path has been sandboxed away, but it seems weird that you'd have access to dofile but not to the path... Basically, you're replicating well-understood and tested module code, which is somewhat odd. If there's more going on here, then ok, but if the only objection is "it's not on the path" when you can just add it to the path, maybe we don't need this after all. :-) [/quote] Message to be posted (in English, please).

luapath.lua - or whatever you want to call it


plugin_path = string.match(GetPluginInfo(GetPluginID(), 6), "(.*)\.*$") .. "\lua\"
package.path = plugin_path .. "?;" .. plugin_path .. "?.lua;" .. package.path

This allows plugin authors to have the lua directory for their plugins added to the lua search path

findfile.lua - or whatever you want to call it


-- this finds a file searching from path including all subdirectories

function scan_dir_for_file (path, tfile)

  -- find all files in that directory
  local t = assert (utils.readdir (path .. "\*"))

  for k, v in pairs (t) do
   if not v.hidden and
      not v.system and
      k:sub (1, 1) ~= "." then
      -- recurse to process file or subdirectory
      if v.directory then
        found = scan_dir_for_file (path .. "\" .. k, tfile)
        if found then
          return found
        end
      elseif k == tfile then
        return path .. "\" .. k
      end -- if 

   end -- if

  end -- for
  return false
end

I use it like this:


require "filefind"

nfile = scan_dir_for_file (GetInfo(60), "telnet_options.lua")

if nfile then
  -- pull in telnet option handling
  dofile (nfile)
else
  print("Could not load telnet_options.lua, please copy it to your plugins directory")
end

Searches for a file given a path, useful for dofile and not having to worry about where the actual file is.
