Javalang

⚠️ IF YOU USE THIS FOR PRODUCTION, IT IS AT YOUR OWN RISK ⚠️

A python script which "generates" a python wheel configuration for a specified OS and architecture of Adoptium's JDK/JRE.

Why?

I was inspired by the ziglang python package, so I decided to take Adoptium's JDK/JRE and ship it as a python wheel.

How do I use this?

After cloning the git repo, it's pretty simple, gen-build-dir.py does most of the heavy lifting:

$ python3 gen-build-dir.py -o linux -a x64
$ cd linux-x64-javalang
$ python -m build # you can make a venv first and install build within there if you want

Now you can find your wheel in linux-x64-javalang/dist. Once you install the wheel, you can use it just like ziglang:

import sys, subprocess

subprocess.call([sys.executable, "-m", "javalang", "--help"])

The operating system supported are:

linux
mac
windows

The architectures supported are any Adoptium supports for the particular OS.

Usage

$ python3 gen-build-dir.py --help
usage: gen-build-dir.py [-h] [-o os] [-a architecture] [-j java_ver] [-r]

Toggle switch ports for link testing.

options:
  -h, --help            show this help message and exit
  -o os, --operating-system os
                        Specify an operating system
  -a architecture, --architecture architecture
                        Specify an architecture
  -j java_ver, --java-version java_ver
                        Specify a version of java (17.0.3+7 or 18.0.1+10)
  -r, --jre             Specify you want the JRE instead of the JDK
