This change updates z2d to 0.12.1 and changes the sprite font path
insetting functionality to use the new path offset abilities released in
the update.
In addition, there has been a slight change to the drawing of E0B5 and
its respective reflection; we now add a 1-pixel horizontal line segment
to each end to force them to be perpendicular. This is because
offsetting pre-expands the curves and ultimately causes the end segments
of the curve itself to have slight non-horizontal angles, which produce
small artifacts at the ends without the forced horizontal ends.
Was brought up as possibly being a build issue here:
https://codeberg.org/vancluever/translate-c/pulls/1
I do think that this is the better approach and seems to be the close
equivalent of the `.zig_ilb` option that's coming with `LazyPath` in
0.17.0 (which is how translate-c behaves there).
I was looking for something like this initially and I _think_ I might
have passed over it to start with because it was a bit hard to determine
the circumstances that `b.graph.zig_lib_directory` would be null, but
upon further examination, I think such cases would be rare if they
happened at all. Rather than default to the cwd in this event though I
just get it to error out - that way we'll know if it ever is the case!
- benchmark: avoid buffers to avoid a memcpy
- build: keep frame pointers on macOS. There was some debug changes from
Zig 0.15 and this helps. Also, Apple actually requires/expects x29 to
always be a frame pointer.
- build/macos: force libSystem symbols instead of compiler-rt
- global: add InitOpts.tool so that ghostty-gen/bench can parse their
own actions in `+action`
- quirks: provide our own vectorized memset. see the comment for more
details why.
- synthetic: fix UB by accessing global.io before it was initialized
- terminal/hash_map: force inline for unique repr types. Zig 0.15
inlined and 0.16 doesn't, measured a huge slowdown in hyperlink
benchmarks.
- terminal: add explicit `@Vector` usage for storing a run of identical cells
as well as for scanning printable cells. This auto-vectorized in Zig
0.15 but not in Zig 0.16. This produces the same assembly.
- unicode: properties and LUT need power-of-two backing integer to avoid
bad LLVM codegen
This commit represents the majority of the work necessary to upgrade
Ghostty to use Zig 0.16.0.
Key parts:
* In addition to its previous responsibilities, the global state now
houses state for global I/O implementations and the process
environment. It is now also utilized in the main application along
with the C library. Where necessary, global state is isolated from key
parts of the implementation (e.g., in libghostty subsystems), and it's
expected that this list will grow.
* We currently manage our own C translation layer where necessary. In
these cases, cImport has been removed in favor of the new external
translate-c package. Due to fixes that have needed be made to properly
translate the dependencies that were swapped out, as mentioned, we
have had to backport fixes from the current translate-c package (and
the upstream Arocc dependency). We will host this ourselves until Zig
0.17.0 is released with these fixes.
* Where necessary (only a small number of cases), some stdlib code from
0.15.2 (and even from 0.17.0) has been taken, adopted, and vendored in
lib/compat.

This updates simdutf to my fork which has a SIMDUTF_NO_LIBCXX option
that removes all libc++ and libc++ ABI dependencies.
From there, the hand-written simd code we have has been updated to also
no longer use any libc++ features. Part of this required removing utfcpp
since it depended on libc++ (`<iterator>`).
libghostty-vt now only depends on libc.
The venerable KDE blur protocol has been replaced with the compositor-
agnostic ext-background-effect-v1 protocol, to be implemented by Niri and
others. The new protocol is much easier to use overall, though we do need
to calculate the blur region manually like X11.
This fixes the VS16 issues found in this test:
https://ucs-detect.readthedocs.io/sw_results/ghostty.html#ghostty
This is also a more robust way to handle VS15/16 in general.
This commit also changes our propeties to be a packed struct which
reduces its size from 4 bytes to 1 and likewise drops our unicode table
size 4x.
This updates uucode. As part of this, the wcwidth implementation was
updated (in uucode) to make emoji modifiers width ZERO. But if they're
standalone, we want them as width 2.
So this also contains a change to force them as width 2 for our width
calculation. This only matters for standalone emoji modifiers, because
when they form a valid grapheme we don't use this width calculation.
- update nixpkgs now that Zig 0.15.2 is available in nixpkgs
- drop hack that worked around compile failures on systems with more
than 32 cores
- enforce patch version of Zig
Update libvaxis. The latest commit of libvaxis includes `uucode` as the
unicode
library. `uucode` has a much cleaner API and is actively developed by a
Ghostty
maintainer (@jacobsandlund). This also has the advantage of removing the
last
transitive dependency Ghostty has that is hosted on codeberg, which
separates us
from the frequent outages.
