Fixes#7500
Supersedes #7582
This commit moves the child exit handling logic from the IO thead to the
apprt thread. The IO thread now only sends a `child_exited` message to
the apprt thread with metadata about the exit conditions (exit code,
runtime).
From there, the apprt thread can handle the exit situation however is
necessary. This commit doesn't change the behavior but it does fix the
issue #7500. The behavior is: exit immediately, show abnormal exit
message, wait for user input, etc.
This also gets us closer to #7649.
Fixes#4800, supercedes #5995
This is a rewrite of #5995 (though the solution is mostly the same since
this is pretty straightforward). The main difference is the rebase on
the new mouse handling we've had since, and I also continue to update
the selection clipboard on non-left-mouse events.
Also fixes crashes in both vanilla GTK and Adwaita implementations of
`closeTab`, which erroneously close windows twice when there are no more
tabs left (we probably already handle it somewhere else).
Besides avoiding copying, this allows consumers to choose to allocate
these structs on the stack or to allocate on the heap. It also gives the
apprt.App a stable pointer sooner in the process.
We were using the Rectangle target for simpler addressing, since that
allows for pixel coordinates instead of normalized coordinates, but
there are downsides to rectangle textures, including not supporting
compressed texture formats, and we do probably want to use compressed
formats in the future, so I'm making this change now.
This was applied to the wrong thing by accident, making the custom
shader ping-pong textures compressed, which breaks custom shaders
because compressed texture formats are not color renderable.
Additionally, I've not switched the compressed format to the correct
texture options, because I tried that and it turns out that the default
compression applied by drivers can't be trusted to be good quality and
generally speaking looks terrible. In the future we can explore doing
the compression ourselves CPU-side with something like b7enc_rdo.
This replaces #7433. The improvements are:
1) Install the systemd user service in the proper directory depending on
if it's a 'user' install or a 'system' install. This is controlled
either by using the `--system` build flag (as most packages will) or by
the `-Dsystem-package` flag.
2) Add the absolute path to the `ghostty` binary in the application
file, the DBus service, and the systemd user service. This is done so
that they do not depend on `ghostty` being in the `PATH` of whatever is
launching Ghostty. That `PATH` is not necessarily the same as the `PATH`
in a user shell (especially for DBus activation and systemd user
services).
3) Adjust the DBus bus name that is expected by the system depending on
the optimization level that Ghostty is compiled with.
Replaces #7676
When building as a flatpak, don't install the systemd user services
since flatpaks can't use them. Remove references to the systemd service
from the DBus service.
Also, customize the app metadata depending on the debug mode.

Cleans up the logic, checks for out of bounds using rows instead of
sel.contains because that excludes cases where a rectangle selection
doesn't include the leftmost column.
Also adds test for clipping behavior of rectangular selections.
Fixes an issue where rectangle selections would appear visually wrong if
their start or end were out of the viewport area, because when cloning
them the restored pins were defaulting to the start and end of the row
instead of the appropriate column.
BPTC is required to be available OpenGL >= 4.2 and our minimum is 4.3 so
this is safe in terms of support. I tested briefly in a VM and didn't
encounter any problems so this should just be a complete win.
(Note: texture data is already automatically compressed on Metal)
Adds support for background images via the `background-image` config.
Resolves#3645, supersedes PRs #4226 and #5233.

These break build from source on Linux for two reasons:
1.) The systemd user service needs to be installed in the `share`
prefix, not the `lib` prefix. This lets it get picked up in `~/.local`
but is also correct for just standard FHS paths.
2.) The `ghostty` path in the systemd user service needs to be absolute.
We should interpolate in the build install prefix to form an absolute
path.
There are two main improvements being made here. First, we move away from using autohash and instead
use a one-shot strategy similar to the Style hashing. Since the GlyphKey includes the Metrics struct,
which contains quite a few fields, autohash was performing expensive and unnecessary repeated updates.
The second improvement is actually just, not hashing Metrics. By ignoring the Metrics field, we can
fit the rest of the GlyphKey into a 64-bit packed struct and just return that as the hash! It
ends up being unique for each GlyphKey in renderGlyph, and is nearly a zero-cost operation.
This ends up boosting the performance (on my machine at least), from around 560fps to 590fps on the
DOOM-fire benchmark.
Without waiting on the xdg-open process on linux/freebsd, we end up with
a defunct (zombie) process after each time we open a URL.
For example, after click on two URLs in a ghostty, here is the output of
`ps ux | grep xdg-open`:
```
pbui 8364 0.0 0.0 0 0 tty7 Z+ 05:03 0:00 [xdg-open] <defunct>
pbui 8453 0.0 0.0 0 0 tty7 Z+ 05:03 0:00 [xdg-open] <defunct>
```
Perhaps we should revisit 695bc30, which removed the wait in the first
place. On my machine running Alpine Linux 3.22, `xdg-open` does not stay
alive and finishes immediately, thus making it safe to call wait (and
not block). This is also the case on my other machine running Ubuntu
24.04: `xdg-open` launches the URL in a browser and terminates
immediately.
Either way, this process must be waited upon eventually. Otherwise, we
will accumulate a collection of defunct processes until the terminal
itself terminates.
Introduces host resources directory as a new concept: A directory
containing application resources that can only be accessed from the host
operating system. This is significant for sandboxed application runtimes
like Flatpak where shells spawned on the host should have access to
application resources to enable integrations.
Alongside this, apprt is now allowed to override the resources lookup
logic.
## Description
Yet another edge case in #2484
When macOS's "Private WiFi address" feature is enabled it'll change the
hostname to a mac address. Mac addresses look like URIs with a hostname
and port component, e.g. `12:34:56:78:90:12` where `:12` looks like port
`12`. However, mac addresses use hex numbers and as such can also
contain letters `a` through `f`. So, a mac address like
`ab💿ef🆎cd:ef` is valid, but will not be parsed as a URI, because
`:ef` is not a valid port.
This commit attempts to fix that by checking if the hostname is a valid
mac address when `std.Uri.parse()` fails and constructing a new
`std.Uri` struct using that information.
It's not perfect, but is equally compliant with the URI spec as
`std.Uri` currently is. Meaning not at all compliant 😅
## Testing instructions
### Unit tests
> [!IMPORTANT]
> I don't know if these tests are run in CI or if they're picked up by
`zig build test`. I get an unrelated crash that mentions `minidump` and
an invalid OSC command when I try to run `zig build test` on my mac.
1. Make sure `zig test src/os/hostname.zig` is passing.
### Manual testing instructions
#### Setup - Enable the "Private WiFi address" setting
> [!IMPORTANT]
> You must be connected to WiFi to be able to test this.
1. Open your mac's "System Settings".
2. Go to Network → Wi-Fi → Details.

3. Set the "Private Wi-Fi address" setting to `Rotating`.

/>
> [!IMPORTANT]
> Now you wait. The private Wi-Fi address will eventually rotate to a
mac address that ends with a non-digit, e.g. `0a`, `ff`, `e2`, etc.
You'll notice this when your shell integration stops working, e.g. you
open a new tab in Ghostty and the shell is in your home directory
instead of whichever directory you had open in your previous tab.
#### Testing the changes
1. Open Ghostty.
3. `cd` to any directory that isn't the default (usually `$HOME`)
directory, e.g. `cd Documents`.
4. Open a new tab (<kbd>Cmd+T</kbd>) or split (<kbd>Cmd+D</kbd>).
5. Assuming the setup steps have been followed you should:
* On `main`: land in `$HOME` in the new tab or split.
* On this branch: land in the same working directory as the original tab
or split.

This adds a new CLI `ghostty +edit-config`. This will open the config
file in the user's specified `$EDITOR`. If Ghostty has never been
configured, this will also create the initial config file with some
default templated contents (the same as that which we introduced back in
Ghostty 1.0.1 or something -- not new behavior here).
This is useful on its own because it will find the correct configuration
path to open. If users are terminal users anyway (not a big stretch
since this is a terminal app), this will allow them to easily edit
config right away.
This is also forward looking: I want to replace our "Open Config" action
to open a Ghostty window executing this command so that users can edit
their config in a terminal editor. This has been heavily requested since
forever (short of a full GUI settings editor, which is not ready yet). I
don't do this in this PR but plan to in a future PR.
Even further forward looking: when we have an API, we can have
`edit-config` auto-reload the config on exit. This isn't possible today
but this is where we'd put that.

Forgot to change these instances when I renamed rgb(a) to bgr(a), which
was breaking test builds. Also went ahead and fixed some code that was
assuming rgba was actually rgba order and added a note to another part.
Also changes color atlas to always use an sRGB internal format so that
the texture reads automatically linearize the colors.
Renames the misleading `rgba` atlas format to `bgra`, since both
FreeType and CoreText are set up to draw color glyphs in bgra.
