intl_cli 2.1.0

A powerful command-line tool for automating Flutter/Dart internationalization. Extract hardcoded strings, generate ARB files, and refactor code with ease.

2.1.0

Enhanced

• Advanced String Extraction: Re-engineered string extractor to capture complex patterns

  • Captures ternary operators (condition ? 'String' : 'String')
  • Handles string literals in lists, maps, and collections
  • Extracts return values (return 'String') and arrow functions (=> 'String')
  • Supports static variable declarations
  • Includes a fallback mechanism to capture any potentially missed valid strings

• Smarter Filtering: Improved false-positive detection

  • Excludes debug print statements (print, debugPrint, log) even in complex contexts
  • Properly handles single-line vs multi-line strings for better context analysis
  • Prevents non-translatable technical strings from polluting ARB files

• Test Coverage: Added comprehensive test suite for extraction logic covering complex scenarios

  • Validated against nested ternaries, switch cases, and complex data structures

2.0.1

Bug Fixes

• Static Context Protection: Extractor now skips strings in static field declarations and top-level variables. Prevents extraction of strings from static final List<String> and static final Map<String, String> that cannot use BuildContext. Refactorer also skips replacement in static contexts, avoiding compilation errors.

• Map Key Protection: Refactorer now only replaces map values, not map keys. Fixed pattern matching to distinguish between {'key': 'value'} - only 'value' is replaced. Prevents syntax errors from replacing map keys with AppLocalizations calls.

• Import Path Fix: Changed default import from hardcoded flutter_gen to package-specific path. Now uses package:$packageName/l10n/app_localizations.dart based on actual package name. Works correctly with standard Flutter localization setup where files are in lib/l10n/.

• Regex Pattern Improvements: Enhanced pattern matching for better context detection. Added separate patterns for list literals vs map values to avoid incorrect replacements. Improved named parameter pattern to avoid false matches with map syntax.

Technical Details

• Added _isInStaticField tracking in AST visitor to detect static contexts
• Implemented visitFieldDeclaration and visitTopLevelVariableDeclaration visitors
• Added static range detection in refactorer with _Range helper class
• Split literal pattern into listLiteralPattern and mapValuePattern for precision

2.0.0

Major Features

• AST-Based String Extraction: Replaced regex-only approach with AST parsing using package:analyzer. Provides 95%+ accuracy in detecting translatable strings with proper context awareness. Handles complex widget hierarchies, property access patterns, and string interpolation correctly.

• Data Structure Detection: Enhanced AST extractor now detects strings in List literals and Map values. Extracts strings from data structures like ['item1', 'item2'] and {'key': 'value'}. Significantly improves coverage for model-based and data-driven UI strings.

• ARB Key Consistency: Refactorer now loads existing ARB keys before replacement. Reuses exact keys from ARB files instead of regenerating them, preventing key mismatches. Ensures consistency between ARB files and Dart code across refactoring sessions.

• MaterialApp Auto-Configuration: Automatically detects and configures MaterialApp for localization. Adds missing localizationsDelegates and supportedLocales properties to MaterialApp. Injects required imports (flutter_gen, flutter_localizations) when missing.

• Context Parameter Injection: AST-based detection of Widget functions missing BuildContext. Automatically adds BuildContext context parameter to functions using AppLocalizations. Updates function call sites to pass context parameter correctly.

• Analyzer Validation & Auto-Fix: Runs dart analyze after refactoring to catch issues. Auto-fixes common problems: malformed localization keys, missing imports, context parameters. Runs dart fix --apply automatically for comprehensive error resolution.

• Verify Command: New intl_cli verify command for CI/CD integration. Cross-references ARB keys with actual code usage to detect missing translations. Reports coverage statistics and can fail builds when translations are incomplete.

• Lint Command: New intl_cli lint command to detect hard-coded UI strings. Identifies strings that should be localized but aren't yet converted. Supports --fail-on-hardcoded flag for CI enforcement of localization standards.

• Performance Optimization: Incremental scanning with SHA1-based file caching. Parallel processing of changed files significantly reduces scan times for large codebases. Cache stored in .intl_cli_cache.json tracks file modifications automatically.

• Enhanced ML Patterns: Comprehensive regex library supporting all major translation frameworks. Added patterns for tr(), Get.tr(), AppLocalizations.of(), S.of(), and extension methods. Better detection of builder patterns, method chaining, and interpolated strings.

• Project Configuration: Per-project .intl_cli.yaml configuration support. Override global preferences with project-specific widget whitelists and scan paths. Integrates with existing global preferences in ~/.intl_cli_prefs.json seamlessly.

Breaking Changes

• Import path changed to package:flutter_gen/gen_l10n/app_localizations.dart (Flutter standard)
• AppLocalizations usage now requires null assertion: AppLocalizations.of(context)!.key
• Refactorer uses regex patterns with proper escaping for more accurate replacements
