Note

High Risk
Major breaking API change plus large parser and release-pipeline changes that directly affect what ships to crates.io, PyPI, and npm.

Overview
Geddes 1.0 narrows the public API to x/y only (uncertainty e removed) and adds ReadOptions (index, block) across Rust, Python, and Node. Parsing is reorganized into dedicated modules with content-based detection and expanded readers (Bruker RAW3/4, GSAS, RAS, UXD, CHI, powder CIF, XRDML, RASX, BRML), plus descending-axis normalization.

Release engineering adds reusable check-rust / check-python / check-node workflows (matrix builds, install tests, fixture validation), wires them into PR/push via check-packages.yml, and makes release tagging wait on full package checks. Publish workflows for npm, PyPI, and crates.io now reuse those checks and publish pre-tested artifacts instead of rebuilding inline; Node gains pack:release, check:package, and publish:packages scripts.

Docs and project hygiene: Zensical site + GitHub Pages workflow, slimmed README, MIT LICENSE, CONTRIBUTING.md, version 0.5.0 → 1.0.0, and shared tests/check_release_version.py for cross-package version/tag alignment.

📝 Walkthrough

Walkthrough

The project adds multi-format XRD readers, option-aware Rust, Python, and Node.js APIs, fixture-based validation, package release workflows, version 1.0 metadata, and documentation.

Changes

Reader API and format support

Layer / File(s) Summary
Reader contract and dispatch
src/lib.rs, src/parser.rs, src/python.rs, node/src/lib.rs, node/index.d.ts
The e field is removed. The scan option becomes index, and block remains available for CIF selection. Readers detect formats from content and normalize descending axes.
Text, Bruker, and XML readers
src/text.rs, src/bruker.rs, src/xml.rs
Readers are added for GSAS, RAS, UXD, CHI, pdCIF, Bruker RAW3/RAW4, XRDML, RASX, and BRML formats.
Reader validation
tests/text_formats.rs, tests/bruker_formats.rs, tests/xml_formats.rs, tests/dispatch.rs, tests/fixture_accuracy.rs, tests/test_python.py, tests/test_rust.rs
Tests cover format detection, pattern selection, encoding, axis ordering, malformed input, fixture accuracy, and x/y validation.

Package validation and release flow

Layer / File(s) Summary
Reusable package checks
.github/workflows/check-*.yml, tests/check_python_package.py, node/scripts/check-package.cjs
Reusable workflows build and test Rust, Python, and Node.js packages across supported platforms and runtimes.
Release packaging
node/scripts/pack-release.mjs, node/scripts/publish-packages.mjs, node/package.json, node/index.js
Native bindings are packed into platform packages and a wrapper package. Packed artifacts are validated and published with version checks.
Release gating
.github/workflows/release.yml, .github/workflows/publish-*.yml, tests/check_release_version.py, tests/release_version_cases.py
Release workflows validate versions, run package checks, transfer artifacts, and create tags only after successful checks.

Documentation and project support

Layer / File(s) Summary

README.md, CONTRIBUTING.md, docs/*, tests/README.md
Documentation describes installation, APIs, supported formats, selection options, testing, fixture generation, and benchmarking.
Documentation site support
zensical.toml, overrides/404.html, requirements-docs.txt, .gitignore, .pre-commit-config.yaml
The documentation site configuration, custom 404 page, pinned documentation dependency, generated-file ignore rules, and fixture-preservation hook exclusions are added.
Fixtures and licensing

In `@node/scripts/check-package.cjs`:
- Line 10: Update publish-packages.mjs at line 10 to replace
Array.prototype.at() with a Node.js 16.0-compatible indexing approach,
preserving the existing value selection. No direct change is needed in
node/scripts/check-package.cjs at line 10 because it does not use .at().

In `@src/text.rs`:
- Around line 436-438: Update the _STEPSIZE validation in parse_uxd so negative
values are accepted for descending UXD scans and only a zero step is rejected.
Preserve the existing invalid-error behavior for zero while allowing
Pattern::from_parsed to normalize descending x and y arrays.

In `@tests/README.md`:
- Line 121: Update the geddes-test repository reference in the tests
documentation so it no longer resolves to the invalid
geddes/blob/geddes-test/README.md path; replace it with the correct repository
URL or plain text if the repository is unavailable.

Node.js Array.prototype.at introduced version 16.6 official documentation

💡 Result:

<search_synthesis>
The Array.prototype.at method was introduced in Node.js version 16.6.0, which was released on July 29, 2021 [1][2]. This addition was part of the update to V8 engine version 9.2.230.21 [1][3]. The feature is documented in the Node.js official release notes for version 16.6.0 [2].

Support Node.js 16.0–16.5 in publish-packages.mjs.

node/package.json declares Node.js >=16, but Array.prototype.at() was added in Node.js 16.6. On Node.js 16.0–16.5, publish-packages.mjs throws before publishing.

Proposed fix
- assert(packages.length === 7 && packages.at(-1).target === null,
+ assert(packages.length === 7 && packages[packages.length - 1].target === null,

check-package.cjs does not use .at() and is not affected.

In `@node/scripts/check-package.cjs` at line 10, Update publish-packages.mjs at
line 10 to replace Array.prototype.at() with a Node.js 16.0-compatible indexing
approach, preserving the existing value selection. No direct change is needed in
node/scripts/check-package.cjs at line 10 because it does not use .at().

RAW4 padding parsed as extra ranges

Medium Severity

ranges_v4 treats a trailing word of 0 as another measurement range. Zero-filled alignment after the last range is therefore parsed as a new scan, then rejected when start/step are zero. ranges_v3 already ignores trailing zeros; RAW4 files with the same padding fail to load.

89-91: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restrict XRDML detection to the document root

src/parser.rs:89-91 matches markers anywhere in the first 65,536 decoded characters. A supported ASCII header or comment can therefore call xml::parse_xrdml, which requires a single XML root named xrdMeasurements and rejects the ASCII file. Restrict the match to a genuine XRDML root, or fall back to text::parse_xy when XRDML parsing fails.
