This modernizes `KeyEncoder` to a new `std.Io.Writer`-based API.
Additionally, instead of a single struct, it is now an `encode` function
that takes a series of more focused options. This is more idiomatic Zig
while also making it easier to expose via libghostty-vt.
libghostty-vt also gains access to key encoding APIs.
This moves our paste logic to `src/input` in preparation for exposing
this as part of libghostty-vt. This yields an immediate benefit of
unit tests for paste encoding.
Additionally, we were able to remove one allocation on every unbracketed
paste path unless the input specifically contains a newline. Unlikely to
be noticable, but nice.
NOTE: This also includes one change in behavior: we no longer encode
`\r\n` and a single `\r`, but as a duplicate `\r\r`. This matches xterm
behavior and I don't think will result in any issues since duplicate
carriage returns should do nothing in well-behaved terminals.
Since #8999, `macos-custom-icon` works when its a fully expanded
absolute path like `/Users/username/dir/icon.icns`, but not when it's
abbreviated as `~/dir/icon.icns`. Users were understandably surprised
and confused by this. This PR adds tilde expansion using `NSString`s
built-in property for this.
Also removed a line from the config docs that seemed erroneous. Given
that the option has a functional default, it seems incorrect to say that
it's required.
In Freetype, measure rect after emboldening, so constraints apply to the
true glyph size like in CoreText.
In CoreText, don't let font smoothing affect the rect (only the canvas).

Uses OSC 133 esc sequences to keep track of how long commands take to
execute. If the user chooses, commands that take longer than a user
specified limit will trigger a notification. The user can choose between
a bell notification or a desktop notification.
Signal handlers are connected to surface objects in two spots - when a
tab is added to a page and when the split tree changes. This resulted in
duplicate signal handlers being added for each surface. This was most
noticeable when copying the selection to the clipboard - you would see
two "Copied to clipboard" toasts. Ensure that there is only one signal
handler by removing any old ones before adding the new ones.
You can pretty simply reproduce a crash on `main` in `Debug` mode by
running `printf "مرحبًا \n"` with your primary font set to one that
supports Arabic such as Cascadia Code/Mono or Kawkab Mono, which will
cause CoreText to output the shaped glyphs non-monotonically which hits
the assert we have in the renderer.
In `ReleaseFast` this assert is skipped and because we already moved
ahead to the space glyph (which belongs at the end but is emitted first)
all of the glyphs up to that point are lost. I believe this is probably
the cause of #8280, I tested and this change seems to fix it at least.
Included in this PR is a little optimization: we were allocating buffers
to copy glyphs etc. from runs to every time, even though CoreText
provides `CTRunGet*Ptr` functions which get *pointers* to the internal
storage of these values- these aren't guaranteed to return a usable
pointer but in that case we can always fall back to allocating again.
Also avoided allocation while processing glyphs by ensuring capacity
beforehand immediately after creating the `CTLine`.
The performance impact of this PR is negligible on my machine and
actually seems to be positive, probably due to avoiding allocations if I
had to guess.
The solution we had before worked in most cases but there were some
which caused problems still. This is what HarfBuzz's CoreText shaper
backend does, it uses a CTTypesetter with the forced embedding level
attribute. This fixes the failure case I found that was causing non-
monotonic outputs which can have all sorts of unexpected results, and
causes a crash in Debug modes because we assert the monotonicity while
rendering.
Reduce potential allocation while processing glyphs by ensuring capacity
in the buffer ahead of time and also using CTRunGet*Ptr functions first
and only allocating for those if that didn't work (it should almost
always work in practice.)
We never used it because our minidump files on Linux didn't contain
meaningful information. With Zig's Writergate, let's drop this and
rewrite it later, we can always resurrect it from the git history.

#8829 fixed the interaction of Powerline glyphs with other symbols, but
regressed in the handling of the Powerline glyphs themselves by letting
them get caught in an early exit that imposes a constraint width of 1.
This PR fixes the regression and adds corresponding tests. Tried to be
somewhat principled about why the special treatment is warranted, hence
the new helper function `isGraphicsElement`.
