* fix: handle YAML parsing edge cases in CustomModesManager
- Add BOM (Byte Order Mark) stripping for UTF-8 and UTF-16
- Normalize invisible characters including non-breaking spaces
- Replace fancy quotes and dashes with standard characters
- Remove zero-width characters that can cause parsing issues
- Add comprehensive test coverage for all edge cases
This fixes the YAML parsing limitations documented in PR #237 by
implementing proper preprocessing before parsing YAML content.
* fix: address PR review comments
- Fix BOM handling to correctly handle UTF-16 (all BOMs appear as \uFEFF when decoded)
- Optimize cleanInvisibleCharacters with single regex pass for better performance
- Prevent duplicate error messages by marking errors as already handled
- Refactor test file to use mockFsReadFile helper function to reduce duplication
- Fix YAML indentation in tests (use spaces instead of tabs)
- Add ESLint disable comment for character class warning (regex is correct)
* fix: prevent YAML line breaks by setting lineWidth to 0
- Added lineWidth: 0 option to all yaml.stringify() calls
- Prevents automatic line wrapping at 80 characters
- Improves readability of YAML output for long strings
- Applied to CustomModesManager, SimpleInstaller, and migrateSettings
* fix: add defaultStringType option to yaml.stringify calls
- Added defaultStringType: 'PLAIN' to minimize formatting changes
- This helps preserve plain scalars when possible
- Works alongside lineWidth: 0 to prevent automatic line wrapping
* refactor: extract problematic characters regex as a named constant
- Move regex pattern to PROBLEMATIC_CHARS_REGEX static constant
- Add comprehensive documentation for each character range
- Improves maintainability and makes the pattern reusable
* test: add comprehensive edge case tests for YAML parsing
- Add test for mixed line endings (CRLF vs LF)
- Add test for multiple BOMs in sequence
- Add test for deeply nested structures with problematic characters
- Ensures robustness across different real-world scenarios
* feat(i18n): add error messages for custom modes in multiple languages
* fix: update tests to expect i18n keys instead of hardcoded strings
- Update CustomModesManager tests to expect translation keys
- Fix YAML edge case tests to match new i18n error messages
- All tests now pass with the i18n integration
* refactor: use strip-bom package and fix error handling
- Replace custom stripBOM method with existing strip-bom package
- Fix duplicate error handling in parseYamlSafely by returning empty object instead of re-throwing
- Addresses review comments from PR #5099

* Replace hardcoded custom modes filename with GlobalFileNames constant
* Remove 'cline' prefix from mcpSettings filename
* Use GlobalFileNames.customModes in modes.ts
* replace two more `cline_mcp_settings` with `mcp_settings` in tests.
* feat: add settings file migration for new file naming convention
- Implement migrateSettings function to rename legacy settings files to new format
- Migrate cline_custom_modes.json to new custom modes filename
- Migrate cline_mcp_settings.json to new MCP settings filename
- Add TODO to remove migration code in September 2025 (6 months after implementation)
- Make activate function async to support migration on startup
* Add associated changeset
* removed unused import
* refactor: move migrateSettings to dedicated utility file
- Extract migrateSettings function from extension.ts to src/utils/migrateSettings.ts
- Update extension.ts to import and use the extracted function
- Update tests to use the real implementation
- Improve dependency injection by passing outputChannel as parameter
- Enhance maintainability by isolating temporary migration code (to be removed Sept 2025)
* Update src/extension.ts
