[gentoo-dev] [PATCH 0/5] Ziglang eclasses for 0.13+

[Eric Joldasov <bratishkaerik@landless-city.net>]

Hello everyone,

This patch series adds new eclasses for packages that use Zig
toolchain with varying level of integration. Since some projects
or ebuilds use only Zig compiler directly, without touching Zig Build
System, I have decided to split eclasses into 2:

* zig-toolchain.eclass: handles dependency on Zig toolchain and
  finds appropriate versions/slots, converts C-style target tuples/triples
  to Zig format and sets environment variables to be used in other
  eclasses and ebuilds. This eclass is more low-level and intended
  to be used by programs and libraries that call "zig" commands directly,
  without having build.zig file and using "zig build" command. For example,
  authors could use "zig build-exe" and "zig test" directly in Makefile,
  or add "zig cc" and compile both C and Zig version of library etc.
  In this patchset it is also used by dev-lang/zig to convert targets
  during bootstrapping, and other logic is suppressed.
* zig-build.eclass: handles working with "zig build" sub-command and build.zig files.
  This eclass is more high-level and for most ebuilds it's the only
  one which needs to be inherited. It sets default functions for
  ebuild phases, deals with dependencies in package manager, allows
  ebuilds and end users to configure used flags, respects multi-threading
  and verboseness preferences, has some small support for cross-compilation
  and so on.

Github PR and discussion here: https://github.com/gentoo/gentoo/pull/37283 .
I have also wrote small generator for Zig ebuild skeletons here:
https://github.com/BratishkaErik/zig-ebuild . Example output in that PR.
It requires dev-lang/zig:9999 to compile, but at runtime it works
with any version supported by eclass (currently 0.13 and 9999).

P.S.: I have not used "git format-patch" and "git send-email" for
a long time, please forgive me and direct if I did something wrong with mail.
