node.js - finding path of require()ing module

trying to find the proper way to determine the path of the module require()ing mine given the following requirements:

must be strict mode compliant
cannot make any assumptions about program args (i.e. process.argv)
must work when required from multiple modules in arbitrary locations a single execution (i.e. my module is cached)

I ended up getting this to work by patching Module._load() and capturing the callers path in a closure as shown here: github

However this doesn't feel right -- I must be missing something.

Patching module._load is the best way I think. You can only get the first module who called your module by module.parent.filename. And the whole children and parent properties of module are only true for the first time load. According to the source code, if it's cached you can't rely on anything. You can try remove yourself from the cache(delete require.cache[__filename];) which then everytime your module is required, you get the right parent, but that will increase your load time.
