i18n Validator

检查翻译文件中的缺失键、损坏的占位符和复数不一致。一条命令，9 项检查，32 种格式，零配置。

9 checks 32 formats Zero config Native Rust binary

问题

用户遇到翻译问题前，问题一直不可见。键缺失时会显示 "settings.billing.title" 等原始路径，而不是真实文本；占位符损坏时会把 "{price}" 显示成文字，而不是 "9.99 美元"；复数格式错误时，计数为零就会崩溃。这些缺陷会绕过代码审核，因为没人会手动比较 15 个本地化文件。

🔑

Missing keys

Blank text or key paths shown to users

🔗

Broken placeholders

{price} displays as literal text instead of $9.99

📁

Orphaned files

Outdated translations confuse the build system

💥

Malformed files

Runtime crashes when users switch languages

大多数验证工具只支持特定格式（仅 JSON 或仅 YAML），而且每个项目都要编写自定义测试代码。翻译缺陷往往到运行时才被发现，此时用户已经看到损坏的 UI。

解决方案

i18n-validate 一次扫描所有翻译文件。它会自动检测目录布局和文件格式，将每种语言与参考语言进行比较，并准确报告问题内容和位置。无需插件、配置或自定义测试代码。

安装

使用您偏好的软件包管理器将其安装为全局 CLI 工具。npm 包内置原生 Rust 二进制文件，无需编译或运行时依赖。

Terminal
npm install -g @i18n-agent/i18n-validate
npm 包为 macOS、Linux 和 Windows 内置预编译原生二进制文件，无需 Rust 工具链。

用法

将工具指向本地化目录。它会自动检测参考语言、目录布局和文件格式。大多数项目无需任何配置。

Terminal
# Zero-config validation
i18n-validate ./locales

# JSON output for scripting
i18n-validate ./locales --format json | jq '.summary'

# CI/CD with JUnit XML
i18n-validate ./locales --format junit -o i18n-report.xml

CI/CD 集成

将翻译验证添加到拉取请求管线。工具会输出 JUnit XML，可与 GitHub Actions 测试报告器、GitLab CI 产物以及任何支持 JUnit 的 CI 系统集成。

.github/workflows/validate-i18n.yml
name: Validate Translations
on:
  pull_request:
    paths: ['locales/**', 'public/locales/**']

jobs:
  validate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Validate translations
        run: npx @i18n-agent/i18n-validate ./locales --format junit -o i18n-report.xml

      - uses: dorny/test-reporter@v1
        if: always()
        with:
          name: i18n validation
          path: i18n-report.xml
          reporter: java-junit
The tool exits with code 1 when errors are found, so it naturally fails CI. Use --strict to also fail on warnings.

支持的格式

验证器由 i18n-convert 驱动，开箱即用地支持 32 种 i18n 文件格式。无需特定格式的插件或配置，工具会根据文件扩展名和内容自动检测格式。

配置

大多数项目使用零配置即可。当您需要控制检查严重程度、设置预期语言或排除开发中的语言时，可在项目根目录创建 .i18n-validate.toml 文件。

.i18n-validate.toml
# .i18n-validate.toml
ref = "en"
expect = ["de", "ja", "fr", "es", "zh-Hans", "pt-BR", "ko"]

[checks]
missing-keys = "error"
extra-keys = "error"
placeholders = "error"
empty-values = "warning"
untranslated = "warning"

[languages.ko]
missing-keys = "warning"    # Korean is WIP

[languages.ar]
skip = true                 # Exclude from validation
