panproto-grammars-functional 0.49.4

panproto grammar pack: functional languages (Haskell, OCaml, Elm, Gleam, Erlang, Elixir, PureScript, F#, Clojure, Scheme, Racket)

panproto-grammars-functional

Companion grammar pack for panproto shipping tree-sitter grammars for functional-language source: Haskell, OCaml, Elm, Gleam, Erlang, Elixir, PureScript, F#, Clojure, Scheme, and Racket.

Companion packs are how the Python wheel adds tree-sitter grammars without bloating the core: panproto itself bundles only the 11-language group-core baseline, and packs like this one extend that surface as separate pip-installable wheels. Installing this package makes its grammars available to panproto.AstParserRegistry() automatically.

Status

Pre-1.0 with arbitrary breaking changes between minor versions. The pack version tracks the workspace panproto version on every release; consumers should pin both to the same minor (e.g. panproto>=0.45,<0.46 and panproto-grammars-functional>=0.45,<0.46).

Python 3.13+ required.

Installation

pip install panproto-grammars-functional

Wheels are published on PyPI for Linux x86_64 / aarch64, macOS arm64 / x86_64, and Windows x86_64. No Rust toolchain is required.

Pulls in panproto>=0.45 as a runtime dependency. If panproto is not already installed, pip resolves it automatically.

Synopsis

import panproto

reg = panproto.AstParserRegistry()
# The grammars from this pack are now in the registry alongside the
# group-core ones (Python, JavaScript, Rust, ...).
# schema = reg.parse_with_protocol("haskell", b"f x = x", "main.hs")

Nothing to import from this package directly. The architecture is described in bindings/python/README.md.

Architecture

Each companion is a separate pyo3 cdylib depending on panproto-grammars with one group-* feature flag. On installation it registers a panproto.grammars entry point that points at its _impl submodule; on construction panproto.AstParserRegistry() walks every such entry point and threads the discovered grammar metadata into the native registry. Cross-cdylib transport uses raw FFI pointers cast to integers; the trust boundary lives on the panproto side.
