Obsidian Localize New

filenames.txt maps every EN file (by permalink) to its locale filename and folder:

[file.{permalink}]
original=EN filename
translation=Locale filename

[folder.EN Folder Name]
original=EN Folder Name
translation=Locale Folder Name

If filenames.txt doesn't exist yet, run the translate-filenames script to generate it:

npx tsx scripts/translate-filenames.ts <locale>

This uses the LLM to propose locale filenames. Review the output with the user before proceeding.

Step 2 — Sync stubs from EN

Creates a stub .md file for every EN page that doesn't yet exist in the locale. Stubs contain EN frontmatter + EN content as placeholder, marked localized: false.

npx tsx scripts/sync-locale.ts <locale> --dry-run   # preview first
npx tsx scripts/sync-locale.ts <locale>             # apply

The sync script places files at locale paths (using filenames.txt), adds EN basename as aliases when filenames differ, and deletes any orphan locale files.

Step 2b — Add redirect aliases for old locale paths

Skip this step entirely if the locale has no prior history in this repo (i.e. git log -- <locale>/ returns nothing). This step only applies to locales that previously had files under a different structure.

If the locale previously had old-format files (before this migration), add backward-compat redirect aliases so old Obsidian Publish URLs continue to resolve.

npx tsx scripts/migrate-locale.ts <locale>          # dry run — review matches
npx tsx scripts/migrate-locale.ts <locale> --apply  # write aliases

For uncertain or unmatched paths, create <locale>/migration-map.json with explicit mappings before running --apply:

{
  "Old/Path without extension": "en-permalink",
  "Another/Old Path": null
}

Set a permalink to null to skip a path. See es/migration-map.json or fr/migration-map.json as examples.

Since filenames.txt is created in this session and not yet committed, the script can't auto-detect the pre-migration commit. Pass the last commit that touched the locale:

git log --oneline -- <locale>/   # find last commit
npx tsx scripts/migrate-locale.ts <locale> --commit <sha>
npx tsx scripts/migrate-locale.ts <locale> --commit <sha> --apply

Step 3 — Translate all stubs

Sends each localized: false file to the LLM for full translation. After translating the body, descriptions are automatically translated in a batched pass.

npx tsx scripts/translate-locale.ts <locale> --dry-run   # preview count
npx tsx scripts/translate-locale.ts <locale>             # translate all

To re-translate descriptions for already-localized files (e.g. after EN descriptions changed):

npx tsx scripts/translate-locale.ts <locale> --translate-descriptions

For large locales (~170 files), run 8 parallel batches then a final cleanup pass:

# Run all 8 in parallel (adjust --limit to cover all files across 8 batches):
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 0   &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 22  &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 44  &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 66  &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 88  &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 110 &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 132 &
npx tsx scripts/translate-locale.ts <locale> --limit 22 --offset 154 &
wait

# Always follow with a final pass (no --limit) to catch any stragglers:
npx tsx scripts/translate-locale.ts <locale>

Parallel batches can claim overlapping work and leave some files untranslated — the final pass without --limit is not optional.

Step 4 — Validate

npx tsx scripts/check-links.ts <locale>         # broken wikilinks
npx tsx scripts/check-terms.ts <locale>         # unofficial terminology
npx tsx scripts/check-terms.ts <locale> --fix   # auto-correct
npx tsx scripts/sort-core-plugins.ts <locale>   # sort core plugins page alphabetically

Fix any broken wikilinks before publishing. The lint script cross-references official plugin/feature names from obsidian-translations.

Two broken-link patterns recur in nearly every locale — look for these specifically after check-links:

• [[Plugins/X]] — if the Plugins folder was renamed (e.g. to "Πρόσθετα", "Plugins"), any hardcoded EN path in content won't match. Do a grep for [[Plugins/ and update to the locale path.
• [[Editing and formatting/Tags\|...]] in the Properties page — this EN path is hardcoded in the source. Update to [[<locale-folder>/Tags-translation\|...]].

Step 5 — Add publish UI strings and language switcher

Create <locale>/publish.strings.js with translated UI strings for the Publish site. Use official app strings from ../obsidian-translations/translations/<lang>.txt for accuracy:

// Locale UI strings — <Language>
(function () {
  function apply() {
    var el;
    el = document.querySelector('.search-bar');
    if (!el) return false;
    el.placeholder = '<Search...>';  // short form — match other locales (e.g. "Suchen...", "Поиск...")
    el = document.querySelector('.site-footer a');
    if (el) el.textContent = '<Powered by Obsidian Publish>';
    el = document.querySelector('.graph-view-outer span:last-child');
    if (el) el.textContent = '<Interactive graph>';
    el = document.querySelector('.graph-expand');
    if (el) el.setAttribute('aria-label', '<Expand>');
    el = document.querySelector('.graph-global');
    if (el) el.setAttribute('aria-label', '<Global graph>');
    el = document.querySelector('.outline-view-outer span:last-child');
    if (el) el.textContent = '<On this page>';
    return true;
  }
  function poll() { if (!apply()) requestAnimationFrame(poll); }
  poll();
  var blText = '<Backlinks>';
  function applyBl() { document.querySelectorAll('.backlinks span:last-child').forEach(function(e) { if (e.textContent !== blText) e.textContent = blText; }); }
  new MutationObserver(applyBl).observe(document.body, { childList: true, subtree: true });
  applyBl();
})();

Add the locale to scripts/locales.json (single source of truth — keep alphabetical, zh last). Then build:

# Edit scripts/locales.json — add entry { "code": "xx", "label": "Native Name", "base": "https://obsidian.md/xx/help" }
# For locales where the directory name differs from the URL code (e.g. pt-BR → pt-br), add a "dir" field
npx tsx scripts/build-publish-js.ts <locale>   # bootstrap locale's publish.js (first time)
npx tsx scripts/build-publish-js.ts            # sync to all locales (also regenerates en/publish.js)

Label conventions: use the native language name, e.g. Português (Brasil) for pt-BR, Español for es. Use the correct locale code (e.g. pt-BR not pt-br) to match the Obsidian Publish URL.

Step 6 — Link Publish site

Before publishing, link the locale to its Obsidian Publish site. The site slug is help-<locale-slug> where the slug is the lowercase version of the locale code (e.g. zh-TW → help-zh-tw, pt-BR → help-pt-br):

cd <locale> && ob publish-setup --site help-<locale-slug>

This writes the Obsidian Publish credentials into the locale's .obsidian/publish.json with the correct path. Without this step, ob publish will report "No publish configuration found".

Note: setup-sites.ts (run automatically by publish-all.ts) re-runs ob publish-setup for every locale before publishing. It uses locales.json to resolve the correct directory name, so mixed-case locales like zh-TW are handled correctly.

Step 7 — Update README

Add the new locale to the language table in README.md. The table is sorted alphabetically by locale code, with en first and zh/zh-TW last. Insert the new row in the correct alphabetical position:

| `<locale>` | https://obsidian.md/<locale>/help/ |

Use the same locale code casing as in locales.json (e.g. pt-BR, zh-TW).

Step 8 — Publish

Publish the new locale using the publish-all script (it handles nav order and site options too):

npx tsx scripts/publish-all.ts <locale>        # publish just this locale
npx tsx scripts/publish-all.ts                 # publish all locales (to push updated language switcher)

Notes

• ANTHROPIC_API_KEY must be set, or scripts/llm-config.json must exist
• The LLM never translates: Obsidian, Sync, Publish, Canvas, Markdown, CSS, API
• translate-filenames.ts automatically loads official plugin name translations from ../obsidian-translations/translations/<lang>.txt and passes them to the LLM — this prevents mismatches between filename and content translations (e.g. "Backlinks" vs "Links inversos")
• Callout types ([!warning]) include explicit titles in EN source — these get translated automatically
• description frontmatter is translated alongside content
• Always run check-links before publishing

Key files

• <locale>/filenames.txt — permalink → locale filename/folder mapping
• <locale>/headings.txt — EN heading → locale heading mapping (auto-maintained)
• scripts/sync-locale.ts — syncs EN structure to locale
• scripts/migrate-locale.ts — adds redirect aliases from old locale paths
• scripts/translate-locale.ts — LLM translation
• scripts/check-links.ts — broken wikilink checker
• scripts/check-terms.ts — terminology checker
• <locale>/publish.strings.js — locale UI strings for Publish site (search, footer, graph, outline, backlinks labels)
• scripts/locales.json — single source of truth for active locales (code, label, base URL, optional dir)
• scripts/build-publish-js.ts — reads locales.json, regenerates LOCALES block in en/publish.js, concatenates publish.strings.js into each locale's publish.js
• scripts/sync-nav-order.ts — translates EN nav order to locale paths; run automatically by publish-all.ts
