cuihua-i18n-helper - AI i18n Assistant 🌍

Ship global products faster with AI-powered internationalization.

An intelligent i18n assistant that automates the tedious parts of internationalization:

• 🔍 Auto-extract translatable strings from your code
• 🤖 AI-translate to 100+ languages in seconds
• ✅ Quality checks for consistency and completeness
• 📊 Reports on translation coverage and health
• 🔄 Sync translations across multiple frameworks

🎯 Why cuihua-i18n-helper?

Traditional i18n workflow is painful:

1. ❌ Manually find all hardcoded strings
2. ❌ Manually create translation keys
3. ❌ Manually copy to each locale file
4. ❌ Manually send to translators
5. ❌ Manually track what's missing
6. ❌ Manually clean up unused translations

cuihua-i18n-helper automates ALL of this.

🚀 Quick Start

Extract translatable strings

Tell your OpenClaw agent:

"Extract all translatable strings from src/"

The agent will:

• Find all hardcoded UI text
• Generate semantic translation keys
• Create locale files for your languages
• Show translation coverage report

Translate to multiple languages

"Translate to Chinese, Japanese, and Spanish"

The agent will:

• Batch translate all strings
• Preserve formatting and placeholders
• Check translation quality
• Report any issues

Check translation health

"Check for missing translations"

The agent will:

• Find missing translations
• Find unused translation keys
• Check for consistency issues
• Generate actionable report

🎨 Features

1. Smart String Extraction 🔍

Automatically detects translatable content:

// Before
\x3Cbutton>Submit\x3C/button>
\x3Cp>Hello, {username}!\x3C/p>
\x3Cinput placeholder="Enter email" />

// After extraction
\x3Cbutton>{t('button.submit')}\x3C/button>
\x3Cp>{t('greeting.hello', { username })}\x3C/p>
\x3Cinput placeholder={t('form.email_placeholder')} />

Supports:

• JSX/TSX (React)
• Vue templates
• Angular templates
• Plain JavaScript strings
• Template literals with variables

2. Intelligent Key Generation 🧠

Creates semantic, readable translation keys:

{
  "button": {
    "submit": "Submit",
    "cancel": "Cancel",
    "save": "Save"
  },
  "greeting": {
    "hello": "Hello, {{username}}!",
    "welcome": "Welcome back"
  },
  "form": {
    "email_placeholder": "Enter email",
    "password_placeholder": "Enter password"
  }
}

Smart features:

• Context-aware naming
• Namespace organization
• Collision prevention
• Consistent naming conventions

3. Batch Translation 🌐

Translate to 100+ languages instantly:

Supported providers:

• ✅ DeepL (best quality)
• ✅ Google Translate (fast, free tier)
• ✅ OpenAI GPT (context-aware)
• ✅ Azure Translator
• ✅ LibreTranslate (self-hosted)

Smart translation:

• Preserves placeholders: {{count}}, {username}
• Handles HTML tags: \x3Cstrong>Bold\x3C/strong>
• Keeps special characters: © ® ™
• Context-aware translations

Example output:

// en.json
{
  "user": {
    "greeting": "Hello, {{name}}!",
    "items_count": "You have {{count}} items"
  }
}

// zh.json (Chinese)
{
  "user": {
    "greeting": "你好，{{name}}！",
    "items_count": "你有 {{count}} 个物品"
  }
}

// ja.json (Japanese)
{
  "user": {
    "greeting": "こんにちは、{{name}}さん！",
    "items_count": "{{count}}個のアイテムがあります"
  }
}

4. Translation Quality Checks ✅

Automated quality assurance:

Checks:

• ✅ Missing translations
• ✅ Placeholder mismatches
• ✅ Inconsistent terminology
• ✅ Excessive string length
• ✅ Untranslated strings (still in source language)
• ✅ HTML tag mismatches
• ✅ Special character issues

Example report:

🔍 Translation Quality Report
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📊 Coverage: 95% (190/200 strings)

⚠️  Issues Found: 5

1. Missing translations (zh.json):
   - user.profile_updated
   - error.network_timeout

2. Placeholder mismatch (ja.json):
   - user.items_count
     Expected: {{count}}
     Found: {count}

3. Excessive length (de.json):
   - button.submit_and_continue
     English: 21 chars
     German: 45 chars (214% longer)

💡 Run with --fix to auto-fix common issues

5. Framework Integration 🔧

Works seamlessly with popular frameworks:

React / Next.js:

import { useTranslation } from 'react-i18next';

function MyComponent() {
  const { t } = useTranslation();
  return \x3Ch1>{t('welcome.title')}\x3C/h1>;
}

Vue / Nuxt.js:

\x3Ctemplate>
  \x3Ch1>{{ $t('welcome.title') }}\x3C/h1>
\x3C/template>

Angular:

\x3Ch1>{{ 'welcome.title' | translate }}\x3C/h1>

Vanilla JS:

import i18n from './i18n';
document.getElementById('title').textContent = i18n.t('welcome.title');

6. CI/CD Integration 🔄

Automate translation checks in your pipeline:

# .github/workflows/i18n.yml
name: i18n Check

on: [pull_request]

jobs:
  check:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Check i18n
        run: |
          openclaw agent run "Check for missing translations"
          openclaw agent run "Verify translation quality"

Pre-commit hook:

#!/bin/bash
# .git/hooks/pre-commit

echo "🔍 Checking i18n..."
openclaw agent run "Check for untranslated strings in staged files"

if [ $? -ne 0 ]; then
  echo "❌ Found untranslated strings. Please add translations."
  exit 1
fi

   Contains English words: "payment"
   Suggestion: Translate to "支付"

3. button.purchase_now (de)
   Too long for button (28 characters)
   Suggestion: Shorten to "Jetzt kaufen"
