localization-analyzer 1.13.1

Professional localization analyzer for Swift/iOS projects with auto-translation

Localization Analyzer

🌍 Professional localization analysis and management tool for multi-platform projects.

Why localization-analyzer?

Unlike other tools that only handle one aspect of localization, this is an all-in-one CLI that covers the entire localization workflow:

• 📦 Modular Support: Handle AI.strings, Common.strings, etc.
• ➕ Add Languages: Create new language with auto-translation
• 🔄 Sync: Keep all languages in sync

Validation & Reporting

• 🔀 Diff: Compare two languages
• 📋 Reports: JSON, Markdown, Console output

Developer Experience

• ⚡ Fast: Multi-threaded analysis
• 💾 Cache: Translation caching for speed

Installation

From PyPI (recommended)

pip install localization-analyzer

From Source

git clone https://github.com/sezginpak/localization-analyzer.git
cd localization-analyzer
pip install -e .

Quick Start

1. Initialize Configuration

cd your-project
localization-analyzer init --framework swift

This creates .localization.yml in your project root.

2. Run Analysis

localization-analyzer analyze --verbose

3. Check Statistics

# View completion stats for all languages
localization-analyzer stats

# Show missing keys per language
localization-analyzer stats --missing

# Export as JSON for CI/CD
localization-analyzer stats --json

4. Add New Language with Translation

# Add Spanish with auto-translation from English
localization-analyzer lang --add es --translate

# Preview first (dry-run)
localization-analyzer lang --add es --translate --dry-run

5. Translate Missing Keys

# Translate missing keys from English to German
localization-analyzer translate --source en --target de

# Force re-translate all keys
localization-analyzer translate --source en --target de --force

6. Sync Languages

# Sync all languages with English (source)
localization-analyzer sync --translate

# Sync specific language
localization-analyzer sync --lang de --translate

7. Compare Languages

# Diff between English and Spanish
localization-analyzer diff --source en --target es

# Fail if missing keys (for CI)
localization-analyzer diff --source en --target es --fail-on-missing

8. Validate Files

# Full validation
localization-analyzer validate --consistency

# Check specific aspects
localization-analyzer validate --syntax
localization-analyzer validate --placeholders

Python API

from localization_analyzer import LocalizationAnalyzer
from localization_analyzer.frameworks import SwiftAdapter
from localization_analyzer.core.file_manager import LocalizationFileManager
from pathlib import Path

# Create analyzer
adapter = SwiftAdapter()
analyzer = LocalizationAnalyzer(
    project_dir=Path('.'),
    adapter=adapter
)

# Run analysis
result = analyzer.analyze()

# Check results
print(f"Health Score: {result.health.score}/100")
print(f"Localization Rate: {result.health.localization_rate}%")
print(f"Hardcoded Strings: {len(result.hardcoded_strings)}")

# File manager for direct key management
file_manager = LocalizationFileManager(adapter, Path('./Resources'))
file_manager.load_all_keys()

# Add a key to specific module
file_manager.add_key(
    key="new.feature.title",
    translations={"en": "New Feature", "es": "Nueva Función"},
    module="Common"
)

Supported Frameworks

Framework	Status	File Format
Swift/iOS	✅ Full Support	.strings (modular)
React	🚧 Coming Soon	.json
Flutter	🚧 Coming Soon	.arb
Android	🚧 Coming Soon	.xml

Key Features Explained

Health Score (0-100)

Calculated based on:

• Localization Rate: % of localized vs hardcoded strings
• Missing Keys: Keys used in code but not in files
• Dead Keys: Keys in files but not used in code
• Consistency: Same keys across all languages

Dynamic Key Detection

Smart detection skips false positives:

// These won't be flagged as missing:
"activity.\(id)".localized      // Dynamic key
"style.\(rawValue)".localized   // Dynamic key

Modular .strings Support

Works with modern Swift projects:

Resources/
├── en.lproj/
│   ├── AI.strings
│   ├── Common.strings
│   ├── Garden.strings
│   └── Settings.strings
└── es.lproj/
    ├── AI.strings
    ├── Common.strings
    └── ...

Translation Caching

Translations are cached to avoid re-translating:

.localization_cache/
└── translations.json
