| For a while I've been bothered by Lua. When I require something, I generally want it to check the directory with my plugin.xml first, and other directories at a later stage. The 'current directory' is rather useless due to the fact that it changes depending on user activity and can't garantuee any relationship to the files you are including. I was finally bothered enough to find out how to solve this little annoyance of mine, and hopefully other people will find it useful too.
-- Adjusted to match WillFa's improvement comment below.
plugin_path = string.match(world.GetPluginInfo(world.GetPluginID(), 6), "(.*\\).*$")
package.path = plugin_path .. "?;" .. plugin_path .. "?.lua;" .. package.path
require "something"

| Bah, just noticed the forums unescaped my backslashes. I'll try to fix that in my original post in a moment.
And yeah, true. Don't know why I didn't do the regular expression like that - probably because I figured Lua's expressions wouldn't like it for some reason. Thanks for minor improvement. ^_^ | | Top |
