Goal is to improve separation between packages and utilities.
Can help with autocompletion/navigate nixpkgs faster.
Also it will help standardize how LUA_PATH is exported across packages,
so that one can more easily make lua changes across nixpkgs (for
instance changing where lua modules are installed).
This fixes a couple of problems:
* Lua 5.1 doesn't have SYSLIBS, so wasn't being linked with any
libraries.
* SYSLIBS doesn't include -lm, so we had to add that manually to
pkgconfig. LIBS includes -lm, so we don't need that hack any more.
This patch was removed in 34f8d7e15a ("lua: one dso patch to rule
them all"), and the reference to it in lua5_4 was removed at the time,
but it seems to have found its way back somehow (probably through a
merge?).
(cherry picked from commit 5b278213a2)
This reverts commit 537a1940e8.
This patch was deliberately removed in 34f8d7e15a ("lua: one dso
patch to rule them all"). The correct fix is to remove the reference
to it that was reintroduced, rather than re-adding the patch.
On other OSes, like NetBSD, these are part of libc. Fortunately, the
Lua Makefile already knows about this, and has a SYSLIBS variable we
can use for this.
We do this same patch in three different ways for four different Lua
versions, even though the structure of the Makefile barely changes
between releases. We can easily consolidate this by just modifying
the Makefile ourselves instead of using patches (Makefiles are very
amenable to this).
This is supposed to be automatically set by Lua's Makefile if PLAT is
set appropriately, but it was being overridden by us overridding
CFLAGS. Setting it manually was a hack. The correct thing to do was
to make sure SYSCFLAGS (where Lua's Makefile puts LUA_USE_LINUX) was
still included in our custom CFLAGS.
This creates a symlink to lua.pc for every name of the file used by Arch:
For a version of Lua (for example, 5.4) we now have:
- lib/pkgconfig/lua.pc
- lib/pkgconfig/lua-5.4.pc
- lib/pkgconfig/lua5.4.pc
- lib/pkgconfig/lua54.pc
The 672c3c1d2a refactor accidentally
dropped the last version component from the source URLs. This change
puts its back.

Recently, we made it harder for external code to use some stdenv-only bash
variables by unsetting them in [1] But Lua's `withPackages` was sourcing some
setup hooks in [2], which required those bash variables.
I say great! We caught something bad: Lua should use normal dependencies, even
though that is harder with `buildEnv`. Now it works that way, and everything is
fine.

- Lua packages now consistently use LUA_PATH/LUA_CPATH rather than a mix
of those and NIX_LUA_PATH/NIX_LUA_CPATH
- Lua libraries are now consistently only added to the search path
variables if:
1) The library actually has a corresponding directory to search
2) The library is not already present in the search path
This should help prevent the search paths from growing overly large
- Fixed bugs in some path helpers
- Changed the affected shell script indentation to 2 spaces; nixpkgs
shell scripts are inconsistently split between 2 and 4 space
indentation, but 2 matches better with the Nix expressions, so IMO it
makes more sense
