Getting current path of the executing Lua script?

[Aapo Talvensaari]

Is there a way to get current path of the executing Lua script in OpenResty?

E.g.

content_by_lua_file 'test.lua';

And in test.lua:

local currentPath = -- something here?

Because otherwise everything seem to be relative to nginx binary path.

Hello,

I use debug.getinfo(1). The returned table will have a 'source' key. I see the following idiom used quite a bit 

local current_path = string.sub(debug.getinfo(1).source, 2, string.len("/scriptname.lua") * -1).

Is there any other ways than using debug-library? I'm not sure I want to add dependency to debug library in any of my libs. But thanks anyway, this is one possibility.

Unfortunately I have not seen another way. If you find a better way please let me know. I do not like this approach either.
