get current working directory in Lua

Question

What\'s the Lua to get the current working directory on Windows XP SP3 (or to get the directory of the currently-running Lua file)? I prefer not to use LuaFileSyste

Answer 1

You should be able to get the currently-running lua file path with:

debug.getinfo(1).short_src;

or

debug.getinfo(1).source;

and then the current directory with a regex:

string.gsub(debug.getinfo(1).short_src, "^(.+\\)[^\\]+$", "%1");

Edit: actually that only works if you're running your lua with the full path. e.g.: "lua.exe C:\test\test.lua" and NOT "lua.exe test.lua"
