The rise of agentic programming has eliminated the natural effort-based
backpressure that previously limited low-effort contributions. It is now
too easy to create large amounts of bad content with minimal effort.
Open source projects have always had poor quality issues, PRs, etc. That
comes with the territory. Unfortunately, the ease and carelessness by
which these are now manifested has increased the "bad" count by 10x if
not more. It's ruining it for the rest of us. This policy is a result of
the bad, and I'm sorry about it.
**Going forward, AI generated contributions will only be allowed for
accepted issues and maintainers.** Drive-by pull requests with AI
generated content will be immediately closed.
**Going further, users who contribute bad AI generated content will be
immediately banned from all future contributions.** This is a
zero-tolerance policy. If you use AI, you are responsible for the
quality of your contributions. If you're using low-effort AI to create
low-effort content, I have no human obligation to help you.
If you are a junior developer who is really trying to learn and get
better, then please put aside the AI, do your best, and I will still
help. I want to help. But I expect effort and organic thinking in
return.

When a tab contains only a single split, resize_split and
toggle_split_zoom actions now return false (not performed). This allows
keybindings marked with `performable: true` to pass the event through to
the terminal program.
The performable flag causes unperformed actions to be treated as if the
binding didn't exist, so the key event is sent to the terminal instead
of being consumed.
- Add isSplit() helper to SplitTree to detect single-pane vs split state
- Update GTK resizeSplit/toggleSplitZoom to return false when single
pane
- Update macOS resizeSplit/toggleSplitZoom to return Bool and check
isSplit
- Add unit test for isSplit method
Currently, if a user clicks the "xmark" button to close the search box,
the main interface does not regain focus until clicked again. This patch
focuses the surface view upon closing.
This adds a new single-file library called "Tripwire" in
`src/tripwire.zig`. This library helps inject failures around `try`
cases for the purpose of testing `errdefer`. It is fully optimized away
in non-test builds (even debug), turning into zero space and zero
assembly.
From this, I've verified (via unit tests w/ tripwire) and fixed a number
of errdefer issues:
* PageList init with non-standard pages that requires more than 1 page
can leak on allocation error on the 2nd+ loop
* Tabstop allocation failure on resize corrupts the internal state
(invalid cols)
* `Screen.selectionString` would leak memory on late allocation failures
* Screen search could leak memory on late allocation failures
* `SharedGrid.renderGlyph` in our font subsystem would corrupt the glyph
cache if failure occurred
* `SharedGrid.init` could leak memory if loading font metrics failed
In addition to the bugs found, there is now tripwire coverage around
more of our core and we should continue to add more. I've also added
significantly more explicit error sets as I found them.
**AI disclosure:** AI wrote some of the tests, but tripwire itself is
all handwritten and everything was reviewed.
Add errdefer cleanup for codepoints and glyphs hash maps in init().
Previously, if ensureTotalCapacity or reloadMetrics() failed after
allocating these maps, they would leak.
Add tripwire test to verify all failure points in init().
Add errdefer to remove cache entry after getOrPut if subsequent
operations fail (getPresentation, atlas.grow, renderGlyph). Without
this, failed renders would leave uninitialized/garbage entries in
the glyph cache, potentially causing crashes or incorrect rendering.
Add tripwire test to verify the rollback behavior.
- Don't expose package attributes that won't build (e.g. on macOS)
- Make the flake generally easier to read since there's none of that
`builtin.foldl' recursiveUpdate` nonsense anymore

See individual commits. An overview:
* Added explicit error sets in more places
* Removed `!` from functions that can't ever fail
* `renderer.cell.Contents.resize` `errdefer` now does proper cleanup
* `renderer.rebuildCells` can now only fail due to allocator OOM
* If shaping fails during rendering, that row is skipped (previously
it'd halt rendering there)
* Failed image rendering setup in the renderer now skips that image
(previously would halt the full frame)
* GPU texture cleanup for failed image setup now works properly
#9417
Adds palette and color scheme uniforms to custom shaders, allowing
custom shaders to access terminal color information:
- iPalette[256]: Full 256-color terminal palette (RGB)
- iBackgroundColor, iForegroundColor: Terminal colors (RGB)
- iCursorColor, iCursorText: Cursor colors (RGB)
- iSelectionBackgroundColor, iSelectionForegroundColor: Selection colors
(RGB)
Colors are normalized to [0.0, 1.0] range and update when the palette
changes via OSC sequences or configuration changes. The palette_dirty
flag tracks when colors need to be refreshed, initialized to true to
ensure correct colors on new surfaces.

Dvorak input (and presumably others) on MacOS causes certain keys to not
work as expected: `[` `]` and `=`.
### Related
This fixes https://github.com/ghostty-org/ghostty/discussions/8743 as
well as an unmentioned problem where bracket navigation and equalize
panes are also broken.
This is similar to https://github.com/ghostty-org/ghostty/pull/8759 but
fixes more of the combos. Switching the `+` binding was not enough to
fix the problem for me since the right bracket physical keys is where
equals should be and overrides the combo.
### What this PR does
Switches several default keybindings from physical key codes to support
alternative keyboard layouts like Dvorak and keyboards with dedicated
plus keys. Effectively:
```diff
- .physical = .equal // or .bracket_left or .bracket_right
+ .unicode = '=' // or '[' or ']'
```
### Details
In testing, I found that all of these bindings need to be fixed
otherwise the bracket physical keys overshadows the dvorak plus key.
This seems like the right solution for the same reason that we don't use
any physical letter or number keys. They move around with different
layouts and `=`, `[`, and `]` are no different than other keys like `-`
and `0` which use unicode in other default keybinds.
With this fix, tab and pane navigation (cmd+[], cmd+shift+[]), as well
as increase font size (cmd+shift+equals and cmd+equals) and equalize
panes (ctrl+cmd+=) now work as expected on dvoark layout on MacOS.
Note, I switch between dvorak virtual layout on the laptop and a
physical dvorak keyboard (passed through qwerty input) so my combos
would need to change depending on which keyboard I was using if we used
physical keys only.
I consulted Claude Code to help try to understand what order and
precedence was being applied in this change, but I wrote and tested the
code myself (however, this is my first `zig` code so take that with a
grain of salt).
Switches several default keybindings from physical key codes
`.physical = .equal // or .bracket_left or .bracket_right`
to unicode characters
`.unicode = '=' // or '[' or ']'`
to support alternative keyboard layouts like Dvorak and
keyboards with dedicated plus keys (like German layouts).
I found in testing that all of these must be fixed at once otherwise
the bracket physical keys overshadew the correct (for dvorak) plus key.
With this fix, tab and pane navigation (cmd+[], cmd+shift+[]), as well
as cmd+shift+equals and cmd+equals work as expected on dvoark layout on MacOS.
# Add GSettings Support for Primary Paste
Implements support for `org.gnome.desktop.interface
gtk-enable-primary-paste` to allow users to disable middle-click paste.
Also refactors GTK Settings access into a reusable generic module.
## Changes
- **NEW**: `src/apprt/gtk/gsettings.zig` - Generic GTK Settings reader
supporting `bool` and `c_int` types, portal-aware for Flatpak/Snap
- **MODIFIED**: `src/apprt/gtk/class/surface.zig` - Reads primary paste
setting and refactors gtk-xft-dpi to use new module
## Behavior
- Setting `false` → Middle-click paste blocked
- Setting `true` or unavailable → Middle-click paste works (default)
- Uses GTK Settings API which automatically uses XDG Desktop Portal in
sandboxed environments
Note: No unit tests added as this is a thin wrapper around GTK Settings
API that's already tested indirectly through surface.zig. Happy to add
tests if desired, though they would require an active display
environment and skip on most CI systems.
