add i18n support for VScode estension - #70
Conversation
…rough VS Code's own l10n chain The extension shipped English-only. It now follows VS Code's display language through the official chain — no custom runtime and no override setting: vscode.l10n.t() in the host, @vscode/l10n in the packages, and package.nls.json / package.nls.zh-cn.json for the manifest's 245 fields (commands, menus, views, settings), which package.json now names as %keys%. Every runtime message lives in apps/extension/l10n/bundle.l10n.json — 2,991 of them, from the extension and from engine, git-service, ai, webview-ui, host-bridge and merge-vscode — and bundle.l10n.zh-cn.json covers all 2,991. Webview pages receive that bundle with the page, as globalThis.__gitstudioL10n, and set <html lang>, so no webview build step is needed. Two things that would have frozen English are handled: module-level label tables are getters (a webview boots l10n as an import side effect before its tables are read), and the plural suffixes are gone — "3 个提交", not "提交s" — by splitting each into a singular and a plural message whose English is byte-identical to the old wording. A button's label is compared against the label it was built from, not against its English text. LLM prompts, GitHub API strings, CSS class names and the crash reporter's fixed titles stay English on purpose. The desktop app and Merge Studio are untouched: their locale parameters are optional and still default to "en". npm run i18n fails if the manifest or the bundle drifts (manifest-nls, bundle-nls); check-purity still holds (engine and host-bridge import nothing but @vscode/l10n) and every in-scope suite, the type-check and the build are green.
Upstream's 68c1c70 — "Fix the bugs the new tests found: push, rebase, merge editor, Windows paths, and more (GitStudioHQ#66)" — merged over the Simplified Chinese commit. Three files conflicted; each was resolved by taking upstream's logic and keeping the l10n wrapper: · apps/extension/src/history/historyContext.ts — both import lines kept. · apps/extension/src/statusBar/syncStatus.ts — upstream's config-based upstream lookup, falling back to l10n.t("its upstream"). · packages/git-service/src/RebaseRunner.ts — upstream's `live` guards on the paused-on-conflict branches, their messages still translated. The message bundle is unchanged (2991 messages, none added or removed) and no new untranslated prose came in, so there is nothing further to localise. One new test, apps/extension/test/stashesView.cov.test.ts, fails: with a stale .git/index.lock in place git 2.43 exits 1 having printed nothing at all, so the toast reads "GitStudio: Stash failed." with no reason to show. Upstream's own code builds that message the same way, so the test is red on 68c1c70 itself and not on this merge.
With a stale .git/index.lock in place, `git stash push` exits 1 having printed nothing on stdout or stderr at all, so the toast read just "GitStudio: Stash failed." — a failure with no reason and nothing to act on. The save path now falls back to "git refused", the phrase the rebase commands already use for a silent git, which is also why no new message needed translating. Pinned by the new apps/extension/test/stashesView.cov.test.ts case, and the "empty reason means no dash" rule notifyStyle.test.ts documents is untouched: failed() still does what it did.
`scripts/i18n/bundle-nls.mjs --write` ran the official extractor straight out of `node_modules`, but `@vscode/l10n-dev` is maintainer tooling that no package.json declares and `npm ci` therefore never installs, so on a fresh clone the regeneration path could not run at all. It now uses a local copy when there is one and otherwise fetches that exact version with npx, and says what to do when that fails. Verified both ways: the bundle comes out byte-identical (2991 messages, 0 added). `package-lock.json` also carried a mirror URL for the new `@vscode/l10n` entry, where every other entry — and upstream's lock — resolves on registry.npmjs.org. Rewritten to match. The integrity hash is unchanged and matches the tarball npmjs publishes, so this is the same artifact.

This may solve #69. |
Upstream's release commit (39e018c: extension 1.17.0, desktop 2.4.0, Merge Studio 1.2.0) renamed GitBrain to GitStudio's AI features, rewording the messages this branch had wrapped. 65 files changed upstream, 8 of them overlapped with the i18n work. Every conflict was resolved by taking upstream's side and keeping the l10n wrap, so English reads exactly as upstream wrote it and Chinese still covers every message: - apps/extension/package.json: `%displayName%`/`%description%` kept and the version follows upstream to 1.17.0; the four reworded manifest fields now say "AI" in package.nls.json and package.nls.zh-cn.json too. - apps/extension/src/ai/{aiCommands,aiFeatures,anthropicProvider,cliProvider, openAiProvider}.ts, apps/extension/src/changes/commitView.ts and packages/webview-ui/src/pr/prCreate.ts: upstream dropped the "GitBrain:" prefixes, and the two template literals it introduced are l10n.t() calls with placeholders again. The source bundle was regenerated: 2987 messages, 15 new — all translated in the Chinese bundle — and 19 retired with the old wording. `npm run i18n`, `npm run check-types`, `scripts/check-engine-purity.sh` and the suites pass; the single extension failure is the known flaky prListView test (33/33 when run alone) and apps/desktop's 12 are this container's missing Electron.

Thanks — this is a really solid piece of work, and the approach is the right one. A few things before we can merge:
- About 250 extension tests fail once Chrome is available (the browser tests skip without it). The test pages in
apps/extension/test/changesPage.tsandrebasePanelPage.tsneed to fill the newl10n.t(...)/l10nWebviewScriptholes. packages/l10nneeds adding toVENDORED_PACKAGESinscripts/merge-studio/layout.mjs(and the matching entry inimport.mjs), or the Merge Studio export stops building.- Please leave these in English: the
Bearer {0}auth headers (openaiCompat.ts,githubApi.ts,openAiProvider.ts), text written into git (the revert commit message inSnapshotProvider.ts:835and the reflog messages), model-facing tool results inpackages/ai/src/agent.ts, and theerrorReporterengine field. - Smaller:
notice()should treat。？！as sentence endings; the webviewl10nTshould replace in a single pass (like@vscode/l10n); escape<in the inlined bundle; add@vscode/l10nto NOTICE; keeppackage.json's escapes as they were.
Your stash fix for git 2.43 is right — thanks for catching that. Happy to help with any of this.
The sweep covered the frames — the ${l10n.t("…")} holes in the templates
— but not the words a sink-based scan never walked: the changes view's
own program builds its buttons, menus and tips from string literals at
runtime, the branch menu and the graph name their items in object
fields, and the host's short labels ("Cancel", "Retry", "Fetch") pass
through promptPick choices. Some 250 of those are wrapped now, and
packages/webview-ui and packages/merge-vscode with them.
The eight review points:
- English exactly where it must be: the Bearer headers
(openaiCompat.ts:72, githubApi.ts:205, openAiProvider.ts:133), the
revert commit message and the reflog messages (SnapshotProvider.ts,
dropCommit.ts, prBranch.ts, prCheckout.ts, changesInTheWay.ts), the
model-facing tool results (agent.ts:179,207), and errorReporter's
engine field.
- notice() ends a sentence on 。？！ too (ui/notify.ts:29).
- The webview's l10nT substitutes in one pass, like @vscode/l10n, and
the inlined bundle escapes "<" so a message cannot end its script
(packages/l10n/src/index.ts).
- packages/l10n is vendored into Merge Studio (layout.mjs:28).
- @vscode/l10n added to NOTICE; package.json's escapes kept.
- The browser tests' pages fill the new holes (test/pageHoles.ts), so
they run again with Chrome; l10nWebview.test.ts runs the emitted
script in a VM and checks the escaping and the one-pass rule.
The bundle is regenerated: 3214 messages, all of them in zh-cn.

All eight done — and a few more, because they led me to labels that were still English. Thanks for the careful read.
What drove the size: while checking the English/git/model boundary I found the user-visible text was still English wherever a sink-based scan could not see it. The Changes view builds its own buttons and menus from string literals at runtime — that is why the template holes read Chinese and "Commit"/"Push" did not — and the branch menu, the graph, the webview panels and the Merge Studio dashboard name their items in object fields. ~250 are wrapped now; the bundle went 2972 → 3214 messages, all of them with zh-cn. One real bug fell out of it: |
A translated clause in another message's slot reads right in English and
wrong in Chinese, so the four sites where the clause sits mid-sentence now
say whole sentences:
- apps/extension/src/views/worktreesView.ts: the "folder is gone" aside,
the "changes were stashed first" one, and the four prune notices.
- packages/webview-ui/src/pr/prPage.ts: "Merged by {0} into {1} ".
Ten messages replace nine fragment keys (3214 -> 3215); English is byte for
byte what it was. The asides that read fine in Chinese (", in {0}",
" (was {0})", " ({1} of {0})") stay as they are.
apps/extension/test/changesViewChinese.test.ts renders the Changes view
with the real zh-cn bundle - the template's holes and the page program's
runtime words both - and asserts the composer buttons and the group
headers come out Chinese: the guard for the bug that started this sweep.
pageHoles.ts learned the `messages` table it needs, and notifyStyle's
toast guard now reads a ternary whose branches are both "GitStudio: "
messages.

This is unbelievable! My AI Agent actually bypassed the sandbox and autonomously obtained my GitHub key, and then posted the above comment . |
Pretty crazy, but I think there is another explanation, if he has access to your CLI, which he does since he commits and pushes changes to git on your behalf. Using He doesnt need to obtain your github key, he just levarages whatever powertools you have at hand, and he loves using the cli without a sandbox. |

Thanks — this is great work, and everything from the review is sorted. Approving and merging.
We'll pick up a few small things on our side:
packages/merge-vscode/src/dashboardController.ts:273:verbs.abortis meant to be the English sentinel, but it's wrapped inl10n.t("Cancel"), so zh-cn shows a bare 取消 instead of "Cancel the merge" in the NO_OP state.- The reflog/revert messages are English templates now, but
snap.label/whatcome from translated undo labels, so they can still carry Chinese. - Translated strings still go into innerHTML/attributes unescaped (e.g.
commit-rail.ts:1453,commit-graph.ts:4876). Fine with today's zh-cn, but worth escaping. syncStatus.ts: the plural reads "replaced the versions" (was "replaced versions").
From here we'll build on this to bring the desktop app and Merge Studio along, and add more languages.
* release: extension 1.18.0, desktop 2.5.0, Merge Studio 1.3.0 Versions, changelog headings (1 Oct 2026) and release notes for 14 languages across all three products (#70, #73, #74). Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * fix(rebase): a reword keeps the commit's description (#75) The interactive rebase workspace read each commit's subject only, so a reword's message box started from the subject and applying it dropped the description. It now reads the whole message (%B, NUL-separated records, as the desktop's rebase view does), seeds the box from it, sizes the box to show it, and the commit counter is translated. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * release: the reword fix in 1.18.0's notes Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * feat: Edit Message… on a commit, in the extension and the desktop app (#75) A commit's menu offers Edit Message… where it can work: on the current branch's line, not a merge or below one. It opens the whole message in an editor, then rewords the commit with a rebase that replays what came after — git-service's multiCommit.ts with a third verb, the path Squash already takes — asks whether branches on rewritten commits come along, and offers Undo. Uncommitted changes and an operation in progress refuse it first. Also: publishedWarning was handed English verbs inside translated sentences, and the too-far refusal spliced in a raw verb; both are whole translated messages now.
