jprototerm
JavaFX canvas terminal prototype using jlibghostty for terminal emulation, Nix for the build environment, and GluonFX/GraalVM Native Image for the Linux binary.
Build
nix build
The package build compiles with Nix-provided OpenJFX 25, jlibghostty, JToml, and GraalVM Native Image directly so it does not depend on Gradle plugin resolution inside the Nix sandbox.
For development:
nix develop
gradle -PjlibghosttyMavenRepo="$JLIBGHOSTTY_MAVEN_REPO" run
gradle -PjlibghosttyMavenRepo="$JLIBGHOSTTY_MAVEN_REPO" nativeCompile
The Gradle project is kept for interactive development and IDE import.
