# OneNote Tools
OneNote Tools is a standalone, local-first browser reader for a tested subset
of Microsoft OneNote `.one` sections and CAB-based `.onepkg` packages. The
parser is native TypeScript, runs in a dedicated module worker, and never
uploads or persists the selected notebook.
It is also an independent application in the add·ideas Toolbox contract: the
source uses the Toolbox SDK shell and manifest, builds with Vite `base: './'`,
and is delivered to Toolbox Portal as an already-built, checksummed static ZIP.
## What version 0.1.0 can open
- Desktop revision-store `.one` sections from the tested OneNote family. The
reader exposes section/page names, stable page IDs, created and updated
timestamps when present, page level, and readable plain text.
- Unfragmented FSSHTTPB-packaged `.one` sections matching the tested Joplin
family. Package cells, revision chains, object groups, and resolved object
and page-space references feed the same bounded content reader.
- Single-cabinet `.onepkg` files whose CAB folders are uncompressed, MSZIP,
Quantum, or LZX compressed. Each contained supported `.one` section is
parsed independently, so one unsupported section does not hide sections that
did parse.
- Package entries, safe normalized paths, uncompressed sizes, compression
metadata, section/page navigation, and structured diagnostics.
The golden tests parse a real Joplin desktop `.one` file with three pages, an
unfragmented 17,197-byte Joplin FSSHTTPB `.one` file with one page, and a real
Joplin `.onepkg` with seven entries, five sections, and seven pages. LZX
`0x1203` and `0x1303`, uncompressed CAB, one- and two-block MSZIP data, and
single- and multi-frame Quantum data are covered by fixtures. The MSZIP and
Quantum fixtures are CAB-level evidence, not a claim about a particular
OneNote `.onepkg` producer.
This is a structural reader, not a full-fidelity OneNote renderer. Images,
tables, ink, embedded files, layout, formatting, links, and exports are not
rendered. Fragmented FSSHTTPB data elements and some producer variants remain
unsupported. See
[format support](docs/FORMAT_SUPPORT.md) for the precise matrix.
There is no Rust/Wasm runtime, server, proxy, upload, telemetry, or notebook
storage. All parsing and CAB/LZX/MSZIP/Quantum decompression is ordinary
browser JavaScript produced from the TypeScript source.
## Use
Run the static build or open it through Toolbox Portal, then drop or choose one
local `.one` or `.onepkg` file. Use **Clear file** to terminate the current
worker and release application references. Browser garbage collection does not
provide a secure-erasure guarantee.
## Development
Node.js 22 or newer is required. The checked-in `.npmrc` contains only the
public package registry mapping and no credential.
```sh
npm ci
npm run dev
npm run check
```
`npm run check` validates manifest synchronization, TypeScript, ESLint,
Prettier, fixture-backed Vitest tests, the production build, and
`toolbox-check dist`.
The application works standalone. A same-origin Toolbox catalogue can be
supplied through the SDK's `?toolbox=` context mechanism. The app uses the SDK
`AppShell` and does not add a second suite-level switcher.
## Release artifact
```sh
npm run release:artifact
(cd release && sha256sum -c onenote-tools-0.1.0.sha256)
```
The ZIP root contains the built static app and manifest plus the changelog,
corresponding-source information, security/support/provenance documents, and
the required project and third-party licence texts. File order and ZIP
timestamps are fixed. Existing artifacts are not overwritten unless `--force`
is passed after `--`.
Toolbox Portal expands the reviewed ZIP below an `apps/<target>/` path and
locks its exact SHA-256. It does not build this repository or import this app
into the portal React tree.
