Re: Relative Requires in Lua

The proper way to do relative requires is:

Thanks, it is quite useful.

BTW, there is an idea how to improve require-related logic
require() should be rewritten so that each call to require() would add current module's directory to the beginning of package.path.

This "extended" package.path will affect only nested invocations of require().

Actually, it would be a stack of directories (synchronized with stack of "require" invocations).

This way you can simply omit concatenation of module names:

thismod/init.lua
-----
local submod = require("submod")
return {submod=submod}
-----

The module "submod" should be searched in the following places in the following order:
1) thismod/submod.lua
2) thismod/submod/init.lua

3) all standard paths (replacing "?" with "submod" in original package.path)
