Expand `~` in `macos-custom-icon` (#9024)

2025-10-06T16:05:34+00:00

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.

Fix Weird Behavior in CoreText Shaper (#9002)

2025-10-06T16:04:48+00:00

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.

gtk: fix duplicate signal handlers (#9001)

2025-10-06T16:04:44+00:00

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.

fix(config): Make `macos-custom-icon` null-terminated (#8999)

2025-10-06T16:04:01+00:00

The config option `macos-custom-icon` wasn't working because, to pass
successfully through the C API to Swift, the string must be
null-terminated.

fix(font): Let powerline glyphs be wide (#8994)

2025-10-06T16:02:58+00:00

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`.
