This introduces the concept of a "dist resource" (specifically a
`GhosttyDist.Resource` type). This is a resource that may be present in
dist tarballs but not in the source tree. If the resource is present and
we're not in a Git checkout, then we use it directly instead of
generating it.
This is used for the first time in this commit for the gresource c/h
files, which depend on a variety of external tools (blueprint-compiler,
glib-compile-resources, etc.) that we do not want to require downstream
users/packagers to have and we also do not want to worry about them
having the right versions.
This also adds a check for `distcheck` to ensure our distribution
contains all the expected files.
1. Refactored Nix devshell/package to make it easier to keep
LD_LIBRARY_PATH & buildInputs in sync (plus make it easier to re-use
in other Nix environment).
2. Added a CI job to ensure that Blueprints are formatted correctly and
that they will compile using `blueprint-compiler` 0.16.0.
3. Reformatted all Blueprints with `blueprint-compiler format`.
Upstream is now mostly pure Zig and the build.zig.zon.* files are
generated directly by zon2nix. The JSON file is no longer used as an
intermediate file but is retained for downstream packager usage.
Closes#6702
This removes our mach-glfw dependency and replaces it with an in-tree
pkg/glfw that includes both the source for compiling glfw as well as the
Zig bindings. This matches the pattern from our other packages.
This is based on the upstream mach-glfw work and therefore includes the
original license and copyright information.
The reasoning is stated in the issue but to summarize for the commit:
- mach-glfw is no longer maintained, so we have to take ownership
- mach-glfw depended on some large blobs of header files to enable
cross-compilation but this isn't something we actually care about,
so we can (and do) drop the blobs
- mach-glfw blobs were hosted on mach hosts. given mach-glfw is
unmaintained, we can't rely on this hosting
- mach-glfw relied on a "glfw" package which was owned by another
person to be Zig 0.14 compatible, but we no longer need to rely on
this
- mach-glfw builds were outdated based on latest Zig practices
This is my third (!) attempt at implementing localization support. By
leveraging GTK builder to do most of the `gettext` calls, I can avoid
the whole mess about missing symbols on non-glibc platforms.
Added some documentation too for contributors and translators, just for
good measure.
Supersedes #5214, resolves the GTK half of #2357

Using `gtk4-layer-shell` still seems like the path of least resistance,
and to my delight it pretty much Just Works. Hurrah!
This implementation could do with some further polish (e.g. animations,
which can be implemented via libadwaita's animations API, and global
shortcuts), but as a MVP it works well enough.
It even supports tabs!
Fixes#4624.
Add a `+boo` command to show the animation from the website. The data
for the frames is compressed during the build process. This build step
was added to the SharedDeps object because it is used in both
libghostty and in binaries.
The compression is done as follows:
- All files are concatenated together using \x01 as a combining byte
- The files are compressed to a cached build file
- A zig file is written to stdout which `@embedFile`s the compressed
file and exposes it to the importer
- A new anonymous module "framedata" is added in the SharedDeps object
Any file can import framedata and access the compressed bytes via
`framedata.compressed`. In the `boo` command, we decompress the file and
split it into frames for use in the animation.
The overall addition to the binary size is 348k.
This adds a new script `update-mirror.sh` which generates the proper
blob format for R2 (or any blob storage) to mirror all of our
dependencies.
It doesn't automate updating build.zig.zon but on an ongoing basis this
should be easy to do manually, and we can strive to automate it in the
future.
I omitted iTerm2 color themes because we auto-update that via CI and
updating all of the machinery to send it to our mirror and so on is a
pain. Additionally, this doesn't mirror transitive dependencies because
Zig doesn't have a way to fetch those from a mirror instead (unless you
pre-generate a full cache like packagers but that's not practical for
day to day development).
It's hugely beneficial just to get most of our dependencies mirrored.
This fixes a regression in 1.1.1/1.1.2 where our PACKAGING docs mention
using `fetch-zig-cache.sh` but it was removed. This commit adds it back,
generating its contents from the build.zig.zon file (via zon2nix which
we use for our Nix packaging).
For packagers, there are no dependency changes: you still need Zig and
POSIX sh. For release time, Ghostty has a new dependency on `jq` but
otherwise the release process is the same. The check-zig-cache.sh script
is updated to generate the new build.zig.zon.txt file.
Adds buildtime and comptime checks to make sure that Blueprints/UI files
are availble and correctly formed. Will also compile Blueprints to UI
files so that they are available to GTK code.
This brings the internal package more in line with how the nixpkgs
package is built. It also handles recursive dependencies better than the
current system.
`zig-gobject` is a set of GObject bindings that allow us to write
GTK-facing code in Zig instead of getting hands dirty with C.
It's been tested and refined in real-life applications and several
GTK contributors agree that it is a marked improvement over using
the C API directly, such as allowing method call syntax and avoiding
many manual `@ptrCast`s.
This commit doesn't actually contain any changes to our preexisting
GTK code — the migration process is intended to begin in chunks,
firstly in self-contained components (e.g. the header bar, overlays,
etc.), and then full-scale migration can begin when we remove non-Adwaita
GTK builds for 1.2. (After all, why port code that you'll remove later
either way?)
Fixes#4554
xev.Process.wait is documented as being equivalent to calling `waitpid`,
i.e. including reaping the process. On Linux, it does this automatically
by using pidfd and the `waitid` syscall. On macOS, it wasn't doing this.
This commit updates libxev to include a fix that explicitly calls
`waitpid` for kqueue.
Multiple fixes to prevent file descriptor leaks:
- libxev eventfd now uses CLOEXEC
- linux: cgroup clone now uses CLOEXEC for the cgroup fd
- termio pipe uses pipe2 with CLOEXEC
- pty master always sets CLOEXEC because the child doesn't need it
- termio exec now closes pty slave fd after fork
There still appear to be some fd leaks happening. They seem related to
GTK, they aren't things we're accessig directly. I still want to
investigate them but this at least cleans up the major sources of fd
leakage.
Adds a Nix VM configuration to run Gnome/Wayland. The primary purpose
will be testing Ghostty in a "clean" environment. I'm going to continue
to experiment with running this in CI to see if we can do some basic
testing of GTK since it's difficult to unit test that code.
To use, run `nix run .#wayland-gnome` in the Ghostty source directory. I
have no idea if this works on macOS. There's probably a lot of extra
stuff that can be trimmed to slim it down.
Whatever directory you run this from will be mounted at `/tmp/shared` in
the VM. The `ghostty` user runs as uid/gid 1000/1000 so that may affect
your ability to read/write that directory if your host system user runs
as a different uid/gid.
If this is something that we'd like to keep, we should add VM
definitions for KDE Plasma and maybe one tiling window manager.
