Project description

ANTLeRinator is a Python 3 utility package to help keeping components of ANTLR v4 in sync.


  • Python >= 3.4
  • pip and setuptools Python packages (the latter is automatically installed by pip)
  • Java SE >= 7 JRE or JDK (the latter is optional)


The quick way:

pip install antlerinator

Alternatively, by cloning the project and running setuptools:

python install


A common form of ANTLeRinator’s usage:

import antlerinator
import argparse
import subprocess

parser = argparse.ArgumentParser()
parser.add_argument('--antlr', default=antlerinator.antlr_default_path)
args = parser.parse_args()

if (args.antlr == antlerinator.antlr_default_path):
    antlerinator.install(lazy=True)['java', '-jar', args.antlr])

Should there be need for manual jar installation, a helper script is available:
