# types-antlr4-python3-runtime — Typing stubs for antlr4-python3-runtime

License: permissive · Maintenance: active · Downloads: 120.3K/mo

## What it is and what it does

This is a type stub package that provides type annotations for the antlr4-python3-runtime library. Type stubs are metadata files that tell static type checkers like mypy, pyright, and ty how to interpret the types in a library, even when the library itself does not include inline type hints. The stubs are maintained as part of the typeshed project and are kept in sync with antlr4-python3-runtime 4.13.* releases.

Installing this package allows developers to catch type errors in code that uses antlr4-python3-runtime without modifying the runtime library itself. The stubs have been tested with mypy 2.3.0, pyright 1.1.411, and ty 0.0.59, ensuring compatibility with modern type checkers.

Use it for:

- Enable mypy or pyright to type-check code that imports antlr4-python3-runtime classes and methods.
- Catch type mismatches in parser and lexer code before runtime in CI/CD pipelines.
- Validate parsing workflows in larger projects that enforce strict type safety.
- Support type-aware development when using antlr4-python3-runtime 4.13.* in production code.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type stubs for antlr4-python3-runtime, enabling static type checkers to validate code that uses ANTLR4 parser generation.

Yes, if you use antlr4-python3-runtime and want static type checking. The package is actively maintained, has no known vulnerabilities, and integrates with standard type checkers. Install it as a development dependency alongside antlr4-python3-runtime 4.13.* to enable type safety in parser-based code.

## Install

pip install types-antlr4-python3-runtime
uv add types-antlr4-python3-runtime
poetry add types-antlr4-python3-runtime

## Installing types-antlr4-python3-runtime

Before you install: Low friction installation. Actively maintained with a release 7 days ago; part of the typeshed project with ongoing upstream synchronization.

License in practice: Apache-2.0 permissive license allows use in most projects without restriction.

Quickstart:

pip install types-antlr4-python3-runtime

# Type checkers (mypy, pyright, ty) now understand antlr4-python3-runtime types
# when analyzing code that imports from antlr4-python3-runtime

Requires Python 3.10 or later. The actual antlr4-python3-runtime package must be installed separately.

Verify before relying:

- Whether the stubs cover all public APIs of antlr4-python3-runtime 4.13.* comprehensively.
- Compatibility with antlr4-python3-runtime versions outside the 4.13.* range.
- IDE autocomplete support across different editors.
