SecLang ANTLR based parser

This repo contains the ANTLR files for a SecLang parser.

Why a new parser?

There has been efforts towards having parsers in different languages. Using ANTLR would allow us to have a common parser and generate parsing engines for different languages easily. This way we would consolidate efforts, and we can have a more robust parser.

Features we (might) want

• Agnostic: no language dependent, parser should be independent of the destination language.
• High Level: writing low level dependent parsing rules is prone to error and makes the language more difficult.
• Can be used from native code, e.g, no dependencies or CGo (this might hurt Coraza, for example)
• Can generate in many languages, and be read and extended by everyone.
• We choose one base implementation language (Python/Go?) and anyone can contribute others.

Usage

Right now this repo contains the ANTLR files and golang and python 3 basic tests.

To run the tests:

go generate ./...
go test ./...

Or for python:

• Get uv first

cd parser
./generate.sh
cd ..
uv sync --all-extras --dev
uv run pytest -vs
