simparse

simparse is a lightweight Rust and Python scanner for simulation project and case metadata.

Supported formats

Design

simparse is meant to compose with existing simulation tools, not replace them. It focuses on lightweight agent workflows: metadata, inventory, quick directory scans, and deciding when a heavier vendor or Python tool should be called next. See tool design principles.

CLI

cargo run -p simparse-cli -- inspect /path/to/model.mph --json
cargo run -p simparse-cli -- inspect /path/to/thermal-model.xml --json --summary
cargo run -p simparse-cli -- inspect /path/to/model.mph --json --summary
cargo run -p simparse-cli -- scan /path/to/history --jsonl

Use --summary for a deterministic, bounded preflight view. It reports total counts with capped samples and explicit parser limitations. Omit it when the full shallow inventory is needed.

FloXML files commonly use the generic .xml suffix. simparse checks their root element, so directory scans include <xml_case> and <sm_xml_case> files while skipping unrelated XML.

Python

maturin develop
python -c "import simparse; print(simparse.inspect('/path/to/model.inp', summary=True))"

Benchmark

python benchmarks/compare.py

This benchmark models one practical agent path: call one external tool to scan a group of public simulation artifacts. The bars include process startup and library import cost. The JSON artifact also records an in-process Python baseline for context; those numbers are useful for library-level comparison, but are not the primary agent tool-call scenario.

The benchmark downloads public URLs listed in benchmarks/public-artifacts.json into target/ and writes artifacts/public-benchmark.json plus artifacts/public-benchmark.svg. Vendor-native parser timings are not included because they require locally licensed software or APIs.
