V wrapper around the C Java Native Interface
This is Work-In-Progress - things will break and things will change.
You will need a working install of the V compiler and a working Java JDK environment (version >= 8).
git clone https://github.com/larpon/jni.git ~/.vmodules/jniTo use jni it is required to set the JAVA_HOME env variable to
point to a valid Java install path that hosts the JNI you want to use.
export JAVA_HOME=/path/to/java/rootTo build the desktop example do:
cd ~/.vmodules/jni/examples/desktop/v_as_library
v run build_and_run.vsh
The build_and_run.vsh script is a simple helper for doing:
export JAVA_HOME=/detect/path/to/java/root
export LD_LIBRARY_PATH="$(pwd)":$LD_LIBRARY_PATH # Needed for Java to load the shared library
v -prod -shared libvlang.v
javac io/vlang/V.java
java io.vlang.V
The jni module supports Java interoperability with both Desktop and Android platforms.
To build the Android example you'll need a working version of vab.
Then simply do:
./vab ~/.vmodules/jni/examples/android/toast
