antlr/grammars-v4 — Grammars written for ANTLR v4; expectation that the grammars are free of actions.

Description and use

The **antlr/grammars-v4** repository houses a collection of language grammars written for ANTLR 4, deliberately keeping them free of embedded actions to stay pure and reusable. These grammars serve as reference implementations and starting points for developers building parsers, compilers, or language tools across a wide range of programming and data languages. The project is maintained as an open‑source resource for the ANTLR community.

Problem

antlr/grammars-v4 may be useful when its README and activity match a concrete workflow.

Outcome

Early or unclear: treat as research material until maintenance, releases, docs, and issue activity are verified.

Evidence

Grammars written for ANTLR v4; expectation that the grammars are free of actions.
