TracyJavaBindings – Java bindings for the Tracy Profiler

Prerequisites

• After cloning the repository, ensure that you have checked-out submodules with git submodule update --init.

Building

JNI Bindings

• You can build the JNI bindings with gradlew jar

Tracy profiler GUI

All commands need to be run in the tracy-jni/tracy subdirectory.

• Create a new build folder under tracy-jni/tracy/profiler.
• Configure the profiler using cmake -B profiler/build -S profiler -DCMAKE_BUILD_TYPE=Release (this only needs to be done once).
• Build the profiler using cmake --build profiler/build --parallel --config Release.
• The built tracy-profiler executable can be found in the profiler/build/Release directory.

Integration

• At runtime, the java.library.path system property should contain a path to the native JNI libraries found in tracy-jni/build/lib/main/release.

Usage Example

import io.github.benjaminamos.tracy.Tracy;

public class TracyTest {
    public static void main(String[] args) {
        // Start profiling
        Tracy.startupProfiler();

        // Allocate and begin zone
        long handle = Tracy.allocSourceLocation(0, "Test.java", "test()", "Test!", 0);
        Tracy.ZoneContext zoneContext = Tracy.zoneBegin(handle, 1);

        // Do work...

        // End zone
        Tracy.zoneEnd(zoneContext);

        // Begin new frame
        Tracy.markFrame();

        // Stop profiling
        Tracy.shutdownProfiler();
    }
}
