sysml-v2-parser

SysML v2 textual notation parser for Rust.

This crate parses SysML v2 and related KerML textual syntax into an AST and also exposes a resilient editor-oriented parsing mode that returns partial AST + diagnostics.

Current status

• library parser for a broad SysML v2 subset
• strict and resilient parsing entry points
• green unit/integration test suite
• green full validation and std-library gates when run with the SysML v2 release fixtures

API

The main public entry points are:

• parse(input) for strict parsing
• parse_for_editor(input) for partial AST + diagnostics

Example:

use sysml_v2_parser::parse;

fn main() {
    let model = parse("package Demo;").expect("valid SysML");
    assert_eq!(model.elements.len(), 1);
}

Development

Run the default test suite:

cargo test

Run formatting/lint checks used in CI:

cargo clippy -- -W clippy::all

Run the full validation suite against the SysML v2 release tree:

cargo test --test validation -- --include-ignored

Fetch the pinned SysML v2 release fixtures into ./sysml-v2-release:

powershell -ExecutionPolicy Bypass -File .\scripts\fetch-sysml-v2-release.ps1

./scripts/fetch-sysml-v2-release.sh

If the release fixtures live somewhere else, set:

SYSML_V2_RELEASE_DIR=/path/to/SysML-v2-Release
