About, licenses, and credits

About is available with or without a database connection. It reports build metadata and provides offline access to application and dependency notices.

About metadata

The page shows:

• application name and version,
• platform,
• MIT OR Apache-2.0,
• repository link,
• linked MongrelDB engine and query versions,
• short MongrelDB git SHA,
• stack summary.

Engine/query values are compiled into Viewer. In Server mode they do not query the remote daemon's version.

License documents

Tab	Bundled content
Viewer license	Full MIT and Apache-2.0 texts
Third-party (Rust)	cargo-about output for direct and transitive crates
Frontend (npm)	Installed runtime and build packages grouped by license text
Acknowledgments	Narrative attribution and direct-dependency roles
Runtime components	WebView, GTK, GLib, Cairo, libsoup, and related notices

Controls support:

• find within the document,
• line wrapping,
• clearing search,
• copying document text.

Documents are compiled from the committed inventory into the application binary and do not require network access. Regeneration after every dependency change is what keeps that inventory aligned with the built artifact.

Credits

Credits loads three structured inventories:

Inventory	Fields
Cargo crates	name, version, license expression, repository
npm packages	name, version, runtime/dev role, license expression, repository
Runtime components	name, license family, SPDX IDs, project URL, notes

Crate and package tables are filterable. Runtime entries with a bundled SPDX text can open that full license.

Regenerate after dependency changes

Install the generator prerequisite:

cargo install cargo-about

Ensure npm packages are installed, then run:

npm ci
scripts/regen-credits.sh

The script requires Bash, Python 3, Cargo, npm's installed package tree, and cargo-about. It:

1. reads Cargo metadata and writes crates.json,
2. reads package-lock.json and installed package manifests,
3. finds npm license files and writes npm-packages.json,
4. groups npm license texts into npm-third-party.md,
5. updates direct-dependency versions in acknowledgments,
6. runs cargo about generate for Rust license text.

Review and commit all generated changes with the dependency change:

src-tauri/legal/crates.json
src-tauri/legal/third-party.md
src-tauri/legal/npm-packages.json
src-tauri/legal/npm-third-party.md
src-tauri/legal/acknowledgments.md

Do not hand-edit generated inventories to hide a dependency. Fix metadata or the generator input, regenerate, and review the result.
