This adds a couple of Nix-based VM integration tests:
- Does `ghostty +version` run successfully?
- Can we create a new terminal window? (This is detected by setting the
background to a color that doesn't appear
normally on the desktop and seeing if we can detect that color in a
screenshot).
Obviously more can be done but I thought that these would be a couple of
good first steps.
The whole test suite can be run with `nix flake check`. Individual tests
can be run with a command like this:
```
nix run .#check.x86_64-linux.<test name>.driver
```
This makes `ucs-detect` available in our Nix environment so that we can
run tests on our Unicode support. In the future, I'd like to modify our
CI to run this too.
This also adds a `./test/ucs-detect.sh` script that runs `ucs-detect`
with consistent options that match the upstream test styles.
- Builds with Zig 0.15 now (but still works just fine with Zig
0.14 projects).
- Fixes a double-free if nix-prefetch-git can't be found or errors out
- Adds support for generating Flatpak package metadata natively.
This adds two explicit `zig build` steps: `run-valgrind` and
`test-valgrind` to run the Ghostty exe or tests under Valgrind,
respectively.
This simplifies the manual Valgrind calls in a few ways:
1. It automatically sets the CPU to baseline, which is a frequent and
requirement for Valgrind on newer CPUs, and generally safe.
2. It sets up the rather complicated set of flags to call Valgrind with,
importantly setting up our suppressions.
3. It enables pairing it with the typical and comfortable workflow of
specifying extra args (with `--`) or flags like `-Dtest-filter` for
tests.
Update to Nix 25.05 which gets us GTK 4.18, libadwaita 1.7, and Zig 0.14.1.
Since Nix updated to Zig 0.14.1, the devshell has been switched to Zig 0.14.1
from zig-overlay as well.
Fixes#7305
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.
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.
Fixes#2171
ZLS has caused us issues in our Nix shell before and I noted when we
first added it that we probably shouldn't. We now pin to release
versions of Zig so I think its reasonable to expect developers to have
ZLS installed themselves with the proper version or not use it at all.
this should reduce the amount of rebuilds that need to occur that due to
the souce changing invalidating the cache
also note that a update to nixpkgs-stable had to occur such that the new
lib functions existed
