# jprototerm
JavaFX canvas terminal prototype using `jlibghostty` for terminal emulation, Nix for the build environment, and GluonFX/GraalVM Native Image for the Linux binary.
JavaFX canvas terminal prototype using `jlibghostty` for terminal emulation and Nix for
the build environment. It builds a plain JavaFX application (JDK 25, JavaFX 25 via Gradle)
packaged as a Nix derivation — no GraalVM/GluonFX native image.
## Build
```sh
nix build
./result/bin/jprototerm
```
The package build uses GluonFX through Gradle so JavaFX native-image metadata is generated by the toolchain that is designed for it. In a strict pure Nix sandbox, Gradle dependencies must be vendored first with `gradle2nix` or a checked-in Maven/Gradle cache.
Install it into a profile (works on NixOS and on a plain Debian box with Nix installed):
```sh
nix profile add .
jprototerm
```
The flake bundles everything the app needs — the JDK 25 runtime, the Maven JavaFX modules
and their native libraries, and the gtk/glib/freetype/X11 libraries they load — **except**
the system OpenGL/graphics drivers. `libGL` is supplied by the host at runtime through a GL
shim in the launcher wrapper, so the same closure runs against NixOS, Mesa, or vendor
(e.g. NVIDIA) GPU drivers.
Gradle dependencies are vendored in `deps.json` for the pure Nix sandbox. Regenerate it
after changing dependencies in `build.gradle` (the update script writes `deps.json` in the
current directory):
```sh
$(nix build .#gradleDepsUpdateScript --no-link --print-out-paths)
```
For development:
```sh
nix develop
gradle -PjlibghosttyMavenRepo="$JLIBGHOSTTY_MAVEN_REPO" run
gradle -PjlibghosttyMavenRepo="$JLIBGHOSTTY_MAVEN_REPO" -Pgluonfx.mainClassName=com.gregor.jprototerm.Main nativeExecutable
gradle run
```
The Gradle project is the source of truth for native JavaFX builds.
