I don’t know if this has been discussed before but would it possible to add
the starting (main) script's path in the default search of directories when
doing ‘require’? And, preferably as the first place to look.
Usually, apps and all their app-specific related modules (other than the
general-purpose libraries) are all located in a single folder.
So, while “require ‘module’” searches for ./module (where “.” is rather
arbitrary because one may be in any subdirectory when starting to run the
program) it does not search the app’s path.
To make it clearer, assume this (for Windows):
\progs\lua\app.lua
\progs\lua\app_lib.lua
app.lua starts with “require ‘app’”
If I run app.lua from inside \progs\lua, no problem – app_lib.lua is found
and loaded. But, if I go to a different directory (say, \temp), and run it
from there using the full path (\progs\lua\app.lua), it will not find
app_lib.lua anymore.
I think the first place to look for required modules would be the (main)
script’s directory. That also allows to override general libraries with
customized versions using the same name but placing them in the app’s
folder.
Thanks. |
