This is matters for cross-compiling where we might not
be able to run the "nvim" binary on the host.
Instead reimplement the helptags extractor as a small
lua script, which we can run on the host using the nlua0
helper already used for other generator scripts.
These are not needed after #35129 but making uncrustify still play nice
with them was a bit tricky.
Unfortunately `uncrustify --update-config-with-doc` breaks strings
with backslashes. This issue has been reported upstream,
and in the meanwhile auto-update on every single run has been disabled.
Tested using cross-compiling from linux:
zig build -Dcross=true -Dtarget=x86_64-windows nvim_bin
Note: not fully functional without a runtime, which still has to be
fuddled with manually
Macos and windows builds require a recent zig 0.15+dev version
As this zig master branch is currently too much in flux, we can't make
our CI depend on zig master.
Revisit CI after zig 0.15 release or at least feature freeze.
Using the preprocessor before generating prototypes provides some
"niceties" but the places that rely on these are pretty few.
Vastly simplifying the BUILD SYSTEM is a better trade-off.
Unbalancing { } blocks due to the preprocessor is cringe anyway (think
of the tree-sitter trees!), write these in a different way.
Add some workarounds for plattform specific features.
INCLUDE_GENERATED_DECLARATIONS flag is now technically redundant,
but will be cleaned up in a follow-up PR as it is a big mess.
Copy whatever was made to work for generated headers:
(1) we need to consider all cmake targets not just main_lib
(2) we need to add the sysroot for macOS
${CONFIG} is an empty string even when configuration is known at
configuration time. $<CONFIG> has to be used at "generation time"
Currently zig's reimplementation of cmake config headers does not
support $<CONFIG> so use a branch to pick the one which works.
NEW BUILD SYSTEM!
This is a MVP implementation which supports building the "nvim" binary,
including cross-compilation for some targets.
As an example, you can build a aarch64-macos binary from
an x86-64-linux-gnu host, or vice versa
Add CI target for build.zig currently for functionaltests on linux
x86_64 only
