feat(cli): add Traditional Chinese (zh-TW) as a UI language option by MikeWang0316tw · Pull Request #3569 · QwenLM/qwen-code

MikeWang0316tw · 2026-04-24T00:42:15Z

Description

Adds Traditional Chinese (zh-TW) as a dedicated UI language option in Qwen Code. Previously, only Simplified Chinese (zh-CN) was available.

This change allows users who prefer Traditional Chinese to select it via /language ui zh-TW or the settings panel.

Changes

packages/cli/src/i18n/languages.ts: Added zh-TW language definition (Traditional Chinese / 繁體中文) to SUPPORTED_LANGUAGES and SupportedLanguage type union.
packages/cli/src/i18n/locales/zh-TW.js: New file — Traditional Chinese translation based on zh.js (Simplified Chinese), converted using opencc.
packages/vscode-ide-companion/schemas/settings.schema.json: Added zh-TW to the language enum and updated the description.
scripts/check-i18n.ts: Added zh-TW.js to the i18n key-matching check, so future PRs will verify that zh-TW.js stays in sync with en.js.
scripts/unused-keys-only-in-locales.json: Updated by running npm run check-i18n.

How zh-TW.js was generated

The Simplified Chinese locale (zh.js) was converted to Traditional Chinese using opencc (s2t converter). This ensures consistent coverage of all i18n keys while using the correct Traditional Chinese characters.

Testing

Built successfully with npm run build
Verified with npm run check-i18n — all keys match between en.js and zh-TW.js
Manual test: /language ui now shows zh-TW as an option

[Critical] npm run check-i18n fails because the new zh-TW locale is not key-synchronized with en.js. Direct key comparison shows 5 missing keys (No server selected, Value:, 中国 (China), 中国 (China) - 阿里云百炼, 阿里云百炼 (aliyun.com)) and 7 extra keys (including the Traditional-character variants of the China/Aliyun labels). Please regenerate or manually sync zh-TW.js so its keys exactly match en.js; only the values should differ.

[Critical] scripts/check-i18n.ts still contains a stale @ts-expect-error for import.meta, and the PR introduces a changed-file typecheck failure because that directive is now unused.

[Critical] Adding zh-TW after the generic zh entry breaks the new locale for users who keep general.language on auto. detectSystemLanguage() walks SUPPORTED_LANGUAGES in order and uses startsWith(), so zh-TW/zh-TW.UTF-8 matches zh first and still resolves to Simplified Chinese.

[Critical] The returned stats object now includes zhTWTranslatedKeys, but CheckResult.stats was not updated to declare that property. That makes npx tsc --noEmit --incremental fail on this PR.

[Critical] scripts/check-i18n.ts now requires stats.zhTWTranslatedKeys, but some return paths still construct stats without this property, which makes npx tsc --noEmit fail. Either remove this field from the type or populate it in every returned stats object.

[Critical] checkKeyMatching is still hard-coded to emit diagnostics for zh.js; the new zh-TW validation reuses it, so missing or extra keys in zh-TW.js will be reported as zh.js, making the new locale validation misleading. Pass a locale label into the helper and use it in diagnostics.

[Critical] This value double-escapes newline sequences (\\n), while the source key uses normal newline escapes. When zh-TW is selected, the CLI will render literal \n text instead of line breaks. The same pattern appears in several other translated values in this file.

[Critical] packages/cli/src/i18n/locales/zh-TW.js 缺少 136 个翻译键（npm run check-i18n 退出码 1）。缺失的键包括 "Status", "Model", "Settings", "Tools", "Yes", "No", "Error", "Back", "cancel", "Hooks", "Extensions", "Workspace" 等基本 UI 文本。使用 zh-TW 语言时这些 UI 字符串将回退显示英文 key 名而非繁体中文。

请使用 opencc (s2t) 从 en.js 或 zh.js 的值补全缺失翻译，然后运行 npm run check-i18n 验证通过。

其余变更（languages.ts、settings.schema.json、check-i18n.ts、useResumeCommand.ts）均正确，构建和测试通过。

[Suggestion] detectSystemLanguage() currently checks environment locales with envLang.startsWith(lang.code). Common POSIX locales use underscores, for example LANG=zh_TW.UTF-8, which does not start with the new zh-TW code and then falls through to the later generic zh entry. Users with a standard zh_TW.UTF-8 environment will still auto-detect Simplified Chinese instead of Traditional Chinese. Consider normalizing separators/case before matching, or comparing normalized code/id values after replacing _ with -.

[Suggestion] Adding zh-TW as a mixed-case language code exposes an existing case-sensitive lookup in getLanguageNameFromLocale(): normalizeOutputLanguage() lowercases user input before calling it, so /language output zh-TW becomes zh-tw and is preserved as the literal string instead of resolving to Traditional Chinese.

Suggested change

code: 'zh-TW',

code: 'zh-tw',

Alternatively, keep the canonical code and make getLanguageNameFromLocale() compare l.code.toLowerCase() against the normalized input.
