- 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 work is mainly targeted at adding the crosshair for when
ctrl/super+alt is pressed. We also add this for when mouse tracking is
enabled so that we show the crosshair when ctrl/super+alt+shift is
pressed at the same time.
I've also changed the event processing logic here because the amount of
keys we have to process has greatly increased. Instead of processing
each individual event, we now process the modifier state.
Additionally, some refactoring has been done geared at starting to
re-work the mouse for the core surface into a something stateful. My
hope is that we can continue to unravel some of this from the core
surface so that we can process key inputs, motion events, and anything
else relevant as inputs to transitions for shape display, click
behavior, etc.
This commit now also moves the ctrlOrSuper handlers to respective parts
in the Key hierarchy, while also adding additional helpers for other
modifiers.
Changes:
- Add WindowsPty, which uses the ConPTY API to create a pseudo console
- Pty now selects between PosixPty and WindowsPty
- Windows support in Command, including the ability to launch a process with a pseudo console
- Enable Command tests on windows
- Add some environment variable abstractions to handle the missing libc APIs on Windows
- Windows version of ReadThread
