Description Tommy Pettersson 2021-01-25 21:32:02 UTC

It would be nice to have Lua search both /usr/ and /usr/local/ for modules.
This is exactly what the patch module_paths.patch in src_prepare() does.
But then, in multilib_src_configure(), the sed expression rewrites all /usr/local/ to /usr/, so /usr/local/ is not added as intended (and /usr/ appears twice in the paths).

After investigating the landscape of multiple scripting languages, I have come to the conclusion that we won't add this feature.

Rationale:

Guile, PHP, Python, Ruby and Tcl do not add any subdirectory of /usr/local to their search path. All of these languages have mechanisms to add extra paths via environment variables.

Perl does add /usr/local to its INC path, but is the odd one out from all the languages I looked at.

Given these facts and the fact that you can always use LUA_PATH to inject a path into the list of search paths, we won't act on this.
