scripts/benchmark.sh generates a deterministic corpus, builds PureXML
in release and a C driver against the SDK's libxml2, times parse,
serialize, and XPath over the same bytes (best-of-N, internal timing,
IO excluded), cross-checks the same XPath count on both sides, and
prints the comparison. First honest baseline recorded in
docs/benchmarks.md: parse ~30x, xpath ~36x, serialize ~5x slower than
libxml2 on a 4.2 MB corpus; these are the numbers #139's optimization
passes burn down. The SAX stage isolation is blocked on #142 (the
public streaming surface is internal, found by this harness).
verification.md listed scripts/check-changelog-touched.sh in the local
gate, but the script did not exist (exit 127). Adds it: when a change set
modifies Sources/*.swift it must also update CHANGELOG.md, comparing the
branch against its base plus the working tree, no-op on a clean base, with
a CHANGELOG_SKIP escape hatch for refactor-only changes. Wires it into
check-all.sh alongside the other shell gates.
Replace monolithic ci.yml with per-platform workflows so each README badge
tracks one job. Scan commit messages for tool-agnostic AI attribution in CI,
sync local hooks to the canon, and refresh README status plus git-discipline Rule 8.
Conform to the vendor-neutral github-discipline canon: the commit-msg and
pre-commit hooks and check-style.sh now reject AI attribution for every
assistant (Codex, Copilot, Gemini, ChatGPT, OpenAI, Anthropic), not just
Claude and Cursor. The no-cursor-attribution workflow is excluded from the
file-content scan since it legitimately quotes the tokens to detect them.
Also wire scripts/check-roadmap.sh into check-style.sh (and grant the CI gates
step issues:read + a token for the epic-coverage query), per the rule that the
roadmap gate runs in the style check.
Follow the mihaela-agents mermaid rule: add a README roadmap using the TileDown
Apple-color status classes (done/review/epic/todo), legend block first, then a
libxml2-parity roadmap showing shipped vs open work. Add docs/rules/mermaid.md
and scripts/check-roadmap.sh (wired into check-all.sh) so the diagrams stay
mechanically checkable.
Root Swift package mirroring PureYAML's structure, rules, and verification
gates. Includes the XML node model (Node, Element, Attribute, QualifiedName),
a working emitter (Serializer) with escaping and pretty/compact options, and
structural validation. The parser surface is stable; parse() raises
notImplemented until the scanner lands, pinned by a test.
- dependency-free, namespaced under PureXML
- portability and style gates carried over (style, namespacing, forbidden
patterns, swiftformat, swiftlint, linux, wasm, windows CI)
- 11 tests passing
