ANTLeRinator

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

Requirements

• Python ~= 2.7 or >= 3.4

• pip and setuptools Python packages (the latter is automatically installed by pip)

• Java SE >= 7 JRE or JDK (the latter is optional)

Install

The quick way:

pip install antlerinator

Alternatively, by cloning the project and running setuptools:

python setup.py install

Usage

A common form of ANTLeRinator’s usage:

import antlerinator
import argparse
import subprocess

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

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

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

antlerinator-install
