# 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.
## Changelog
Release notes and migration hints: [`CHANGELOG.md`](CHANGELOG.md).
## 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:
```rust
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:
```bash
cargo test
```
Run formatting/lint checks used in CI:
```bash
cargo clippy -- -W clippy::all
```
Run the full validation suite against the SysML v2 release tree:
```bash
cargo test --test validation -- --include-ignored
```
Fetch the pinned SysML v2 release fixtures into `./sysml-v2-release`:
```powershell
powershell -ExecutionPolicy Bypass -File .\scripts\fetch-sysml-v2-release.ps1
```
```bash
./scripts/fetch-sysml-v2-release.sh
```
If the release fixtures live somewhere else, set:
```bash
SYSML_V2_RELEASE_DIR=/path/to/SysML-v2-Release
```
