jextractGUI is a GUI wrapper for the jextract tool written in JavaFX. If offers several benefits over using the command line tool:

• Symbol inspection and filtering. No need to dump symbols into an @argfile and manually specify the ones to include.
• Detailed presentation of the header symbols.
• Automatic command creation for inspection or copying into a CLI/script. The CLI uses error-prone unchecked strings.
• Ease of use when working with multiple headers at once.

Instructions akin to -help are provided through the help buttons.

⚠️jextract is in early-access and by extension so is this project. There is no attempt to support previous jextract builds, and future builds can break previous behaviors. The versions of this project will be 0.x.x for the jextract EA builds, and will switch to 1.0.0 when it supports the first jextract GA build.

Download

Pre-built executables (using jpackage) for Windows, Linux, and MacOS are available under Releases. Supported architectures mirror jextract's support. Java and jextract dependencies are included (there's no need to download anything else).

Building and running from source

• From Gradle: use the provided Gradle wrapper.
  • compileJava/build download the jextract dependencies.
  • run starts the application.
  • jpackageImage builds the executables.
• From the IDE:
  • Compile with --enable-preview.
  • Run with --enable-preview --enable-native-access=org.openjdk.jextract.
  • The lib directory might need to be added to java.library.path (or to any directory it includes by default).

💡Tracing of native calls can be enabled with -Djextract.trace.downcalls=true for both the pre-built executables and local builds.

🔌IDE developers are welcome to create an integration (e.g., via a plugin) based on this work into their IDE.
