DualTran for Obsidian

Translate selections and whole notes inside Obsidian with Google or your own AI model (BYOK, 20+ providers) — powered by @dualtran/core, the engine extracted from the DualTran browser extension.

Commands

• Translate selection (replace) — replaces the selection with the translation.
• Translate selection (insert below) — keeps the original and inserts the translation right below it.
• Translate note to a new file — translates the whole note into a new file next to the original.

Development

node scripts/sync-core.mjs   # builds + vendors @dualtran/core (CORE_REPO env to override)
npm install                  # installs devDeps + the vendored tarball
npm test                     # unit + integration suites
npm run build                # produces main.js (production, minified)
npm run verify               # test + build + dist guards (manifest/versions/size/node-refs)

npm run dev builds with inline source maps and watches (main.js).

Architecture

• src/bridge.ts — host-agnostic translation logic (Google batch via core.translateGoogle, AI via core.streamChat); fully dependency-injected.
• src/coreAdapter.ts — the only module that imports the vendored core.
• src/editorOps.ts — pure editor-insertion helpers (Obsidian Editor-shaped).
• src/settings.ts — settings shape, defaults and sanitization.
• src/main.ts — plugin wiring: commands, settings tab, requestUrl-based fetch adapter (no CORS on desktop or mobile).

Releasing

1. Bump manifest.json + package.json + versions.json (minAppVersion map).
2. npm run verify green.
3. Commit, tag without a v prefix matching the manifest version exactly, push the tag, then attach main.js, manifest.json and styles.css (if any) to the GitHub release.
4. Submit via community.obsidian.md (see docs/SUBMISSION.md in the repo — added with the submission materials).
