Fixes#9322
SwiftUI `Text` has huge performance issues. On my maxed out MBP it hangs
for any text more than 100KB (it took ~8s to display it!). `TextEditor`
with a constant value works much better and handles scrolling for us,
too!
Fixes#9132
We were processing our window size defaults separate from our window
position and the result was that you'd get some incorrect behavior.
Unify the logic more to fix the positioning.
Note there is room to improve this further, I think that all initial
positioning could go into the controller completely. But I wanted to
minimize the diff for a backport.
This adds a set of Wasm convenience functions to ease memory management.
These are all prefixed with `ghostty_wasm` and are documented as part of
the standard Doxygen docs.
I also added a very simple single-page HTML example that demonstrates
how to use the Wasm module for key encoding.
This also adds a bunch of safety checks to the C API to verify that
valid values are actually passed to the function. This is an easy to hit
bug.
**AI disclosure:** The example is AI-written with Amp. I read through
all the code and understand it but I can't claim there isn't a better
way, I'm far from a JS expert. It is simple and works currently though.
Happy to see improvements if anyone wants to contribute.
This makes `libghostty-vt` build for freestanding wasm targets (aka a
browser) and produce a `ghostty-vt.wasm` file. This exports the same C
API that libghostty-vt does.
This commit specifically makes the changes necessary for the build to
build properly and for us to run the build in CI. We don't yet actually
try using it...
Fixes a crash when NSLocale returns nil for languageCode or countryCode
properties. This can happen when the app launches without locale
environment variables set.
The crash occurs at `src/os/locale.zig:87-88` when trying to call
`getProperty()` on a nil object. The fix adds a null check and falls
back to `en_US.UTF-8` instead of dereferencing null.
## Testing
Tested by running with locale variables unset:
```bash
unset LC_ALL && ./zig-out/Ghostty.app/Contents/MacOS/ghostty
```
Before: segmentation fault
After: launches successfully with fallback locale
Fixes#8900
Our xterm modify other keys state 2 encoding was stripped consumed mods
from the keyboard event. This doesn't match xterm or other popular
terminal emulators (but most importantly: xterm). Use the full set of
mods and add a test to verify this.
Reproduction:
```
printf '\033[>4;2m'
cat
```
Then press `ctrl+shift+h` and compare across terminals.
Closes#8430
A few questions:
* Should I set a default keybind for `toggle-mouse-reporting`? The issue
mentioned one, it's currently unset.
* Am I handling the `toggle-mouse-reporting` action properly in
`performAction` (gtk) / `action` (macos)?
Copilot was used to understand the codebase, but code was authored
manually.
This cleans up some of our termio exec code by unifying process launch
state into a single union type. This makes it easier to distinguish
between the current two mutually exclusive modes of launching a process:
fork/exec and flatpak dbus commands.
It also ensures everyplace we touch related to process launching is
forced to address every case (exhaustive switch handling). I did find
one resource cleanup bug based on this cleanup, which is also fixed
here. This just improves memory slightly so it's not a big deal.
If we add future ways to launch processes, we can add a new union case.
For example, I originally had a `posix_spawn` option while I was
experimenting with that before abandoning it (see #9274).
The host validation code previously expected IPv6 addresses to be
enclosed in [brackets], but that's not how ssh(1) expects them.
This change removes that requirement and reimplements the host
validation routine to check for valid hostnames and IP addresses (IPv4
and IPv6) using standard routines rather than custom logic.
Fixes#9251

std.net.isValidHostname is currently too generous. It considers strings
like ".example.com", "exa..mple.com", and "-example.com" to be valid
hostnames, which is incorrect according to RFC 1123 (the currently
accepted standard).
Until the standard library function is improved, we can use this local
implementation that does follow the RFC 1123 standard.
I asked Claude to perform an audit of the code based on its understand
of the RFC. It suggested some additional test cases and considers the
overall implementation to be robust (its words) and standards compliant.

`fish_add_path` by default updates the `fish_user_paths` universal
variable which makes the modification persist across shell sessions.
The integration also tries to update the `fish_user_paths` when the
desired path already appears in the `PATH` environment variable but not
in `fish_user_paths`. Because `fish_user_paths` will always be inserted
before the inherited `PATH` env. This makes the added path
unintentionally has a higher priority.
This patch fixes the above issues by adding `--global` and `--path`
options to `fish_user_paths` which limits the modification scope and
ensures that the path won't be added if it already exists in `PATH`.

This fixes the source of a deadlock that some tip users have hit. If our
surface mailbox is full and there is a dirty scrollbar state, then
drawFrame would block forever trying to queue to the surface mailbox.
We now fail instantly if the queue is full and keep the scrollbar state
dirty. We can try again on the next frame, it's not a critical thing to
get updated.

NSScreen instances can be garbage collected at any time, even for
screens that remain connected, making NSMapTable with weak keys
unreliable for tracking per-screen state.
This changes the quick terminal to use CGDisplay UUIDs as stable
identifiers, keyed in a strong dictionary. Each entry stores the window
frame along with screen dimensions, scale factor, and last-seen
timestamp.
**This should make quick terminal size restore more stable than 1.2.2.**
Rules for pruning:
- Entries are invalidated when screens shrink or change scale
- Entries persist and update when screens grow (allowing cached state to
work with larger resolutions)
- Stale entries for disconnected screens expire after 14 days.
- Maximum of 10 screen entries to prevent unbounded growth
