Rather than storing a list of errors we now store a list of
"diagnostics." Each diagnostic has a richer set of structured
information, including a message, a key, the location where it occurred.
This lets us show more detailed messages, more human friendly messages, and
also let's us filter by key or location. We don't take advantage of
all of this capability in this initial commit, but we do use every field
for something.
This continues our work to improve the amount of explicit error sets
we use in the codebase. Explicit error sets make it easier to understand
possible failure scenarios, allow us to use exhaustive matching, create
compiler errors if errors are unexpectedly added or removed, etc.
The goal eventually is 100% coverage but we're not even close yet.
This just moves us a little closer.
If the apprt is GTK add the GTK and the libadwaita version info to the
`+version` action. This information is available in the log but it may
be more accessible here.
- Make canvas geometry primitives generic, use `Rect(u32)` for `rect`
function, so that we don't have to worry about negatives or rounding.
- Make `Quads` struct packed just in case it gets non-comptime use in
the future.
- Clarify comment on why we're discarding out of range pixels + runtime
unreachable for any other type of error which we shouldn't ever see.
- Move z2d import above in-tree imports.
Fixes#2432
On macOS, processes with an NSApplicationMain entrypoint do not have
access to libc argc/argv. Instead, we must use NSProcessInfo. This
commit introduces an args iterator that uses NSProcessInfo, giving us
access to the args.
This also fixes an issue where we were not properly skipping argv0 when
iterating over the args. This happened to be fine because we happened to
ignore invalid args but it introduces a config error.
This takes advantage of CSS variables and color expressions to improve
the `window-theme=ghostty` support. The only visibile difference from
the previous implementation is that the header bar will darken if the
Ghostty window is in the background, which is standard for GTK apps.
This is conditional at runtime. If Ghostty detects that you're running
against GTK 4.16 or newer it will use the CSS variables and color calcs.
If you're running against older versions it will use CSS classes to
achieve nearly the same effect.
More complete coverage of the Symbols For Legacy Computing block,
including characters from Unicode 16.0.
Pixman and the web canvas impl for Canvas have been removed in favor of
z2d for drawing, since it has a nicer API with more powerful methods,
and is in Zig with no specific platform optimizations so should compile
to wasm no problem.
Use a single unified function for intersection-style line drawing chars,
and one for fractional block characters. Add a ground truth image based
on this commit for the regression test (differences from before changes
validated visually, 1 incorrect rendering actually fixed)
Fixes a bug caused by the renderer logic assuming this behavior and not
advancing the run iterator when skipping foreground elements in cells
with the invisible flag set.
This simplifies the math for calculating scroll vectors based on mouse
scroll events. This was done to fix inverted horizontal scrolling on
macOS with natural scrolling enabled. Many assertions were added for
assumptions and our preconditions are clearly documented.
The preconditions are:
* Apprt scroll offsets are negative down/left, positive up/right
* Terminal vertical scroll is postive down, negative up (opposite
since scroll for a terminal means how many rows to move down).
* `Surface.scrollCallback` is always call with an apprt offset.
* Apprt is responsible for implementing natural scrolling. Surface
always assumes negative is down/left.
