Fixes#1724
See background in #1724. The general idea is that for Ghostty
invocations via xdg-terminal-exec, we set the initial title to the
command automatically so that window managers can modify the styling.
We only do this for xdg-terminal-exec because that protocol/spec is
specifically for the scenario that the terminal is being used to launch
a command from the desktop environment.
Fixes#1802
This allows `keybind` configurations to map to any Unicode codepoint. This enables keybindings for which we don't have a registered keycode or for custom keyboard firmwares that may produce arbitrary text (but the Ghostty support is limited to a single codepoint).
The `keybind` syntax is unchanged. If a bound character doesn't map to a known logical key that Ghostty knows about, we map it to a Unicode codepoint. The unicode codepoint is compared against the _unshifted codepoint_ from the apprt key event.
Note that this binding is to a single _codepoint_. We don't support arbitrary sequences of characters or multi-code point graphemes for keybindings due to the complexity in memory management that would introduce.
This also provides a good fallback for scenarios where it might make sense to educate Ghostty about a key code or fix a bug in our keyboard input system, but the unicode data is correct. In that scenario, unicode key binds should allow key binds to still work while we investigate the input issues.
Example:
```
shift+ö=text:hello
```
This now works as expected on a US hardware keyboard with the Hungarian keyboard layout.
Fish automatic integration taken as an example.
Just like fish, Elvish checks `XDG_DATA_DIRS` for its modules.
Thus, Fish integration in zig is reused, and integration in
Elvish now removes `GHOSTTY_FISH_XDG_DIR` environment variable
on launch.
Fixes#1409
Fixes macOS 14.4,14.5 kernel panics
As noted in the comment in this diff, I've decided to default this to
true because it fixes a couple _really bad_ issues for macOS users. For
macOS users on 14.4 and 14.5 (latest released as of this commit), this
resolves or at least heavily mitigates a possible kernel panic.
This also fixes#1409 where external displays over certain connections
such as DisplayLink would be unusably slow to render.
Allows for high dpi displays to get odd numbered pixel sizes, for
example, 13.5pt @ 2px/pt for 27px font. This implementation performs
all the sizing calculations with f32, rounding to the nearest pixel
size when it comes to rendering. In the future this can be enhanced
by adding fractional scaling to support fractional pixel sizes.
This change adds automatic bash shell detection and integration.
Unlike our other shell integrations, bash doesn't provide a built-in
mechanism for injecting our ghostty.bash script into the new shell
environment.
Instead, we start bash in POSIX mode and use the ENV environment
variable to load our integration script, and the rest of the bash
startup sequence becomes the responsibility of our script to emulate
(along with disabling POSIX mode).
We don't actually use libc wcswidth to determine width and even if we
did some terminals use wcwidth (which behaves differently), some use
the Python wcswidth library (which behaves differently), etc. The
reality is there is no real consistency on "legacy" behavior so by
naming it "legacy" we show that we're doing our best but also gives us
wiggle room to change our behavior in the future.
Functionally nothing changes with this commit.
This adds a new option to the shell integration feature set, `no-title`.
If this option is set, the shell integration will not automatically
update the window title.
Add support for configurable fonts for window and tab titles. This is
only implemented for macOS (and could be macOS-only if other platforms
aren't able to support this using their windowing toolkits). It plays
nicely with regular and titlebar tabs.
Fixes#1403
This changes the behavior of `grapheme-width-method = unicode` to change
the default state of mode 2027 to true. Prior to this, setting this
config would force grapheme clustering regardless of mode 2027. Now,
this only sets the default and running TUI programs can disable it if
they want.
