| ## Description | ||
|
|
||
| Fixes #5532 | ||
|
|
||
| This PR expands the current image-only attachment system to support all file types while maintaining full backward compatibility. The enhancement replaces the camera icon with a paperclip icon to better reflect the general file attachment functionality. | ||
|
|
||
| ## Changes Made | ||
|
|
||
| ### UI Updates | ||
| - **Icon Change**: Replaced camera icon with paperclip icon in ChatTextArea component | ||
| - **Tooltip Update**: Changed from "Add images to message" to "Attach files to message" | ||
| - **Accessibility**: Updated aria-label to reflect new functionality | ||
|
|
||
| ### Backend Enhancements | ||
| - **New File Processing**: Created comprehensive process-files.ts with support for all file types | ||
| - **MIME Type Detection**: Intelligent file type categorization (images, documents, code files, data files, etc.) | ||
| - **File Size Validation**: 10MB maximum file size limit with proper error handling | ||
| - **Smart Content Handling**: Text files displayed as content, binary files encoded as base64 | ||
|
|
||
| ### Message System Updates | ||
| - **New Message Types**: Added "selectFiles" to WebviewMessage and "selectedFiles" to ExtensionMessage | ||
| - **Dual Support**: Both image-only and general file workflows supported simultaneously | ||
| - **Handler Updates**: Extended webview message handler to process both message types | ||
|
|
||
| ### Internationalization | ||
| - **Translation Updates**: Added "attachFiles" key to all supported languages: | ||
| - English: "Attach files to message" | ||
| - French: "Joindre des fichiers au message" | ||
| - Korean: "메시지에 파일 첨부" | ||
| - Turkish: "Mesaja dosya ekle" | ||
| - Russian: "Прикрепить файлы к сообщению" | ||
|
|
||
| ### Backward Compatibility | ||
| - **Preserved Functionality**: Original process-images.ts remains unchanged | ||
| - **Dual Function Support**: New process-files.ts includes backward-compatible selectImages() function | ||
| - **Message Type Compatibility**: Both "selectImages" and "selectFiles" message types supported | ||
| - **Component Props**: ChatTextArea accepts both onSelectImages and onSelectFiles props | ||
|
|
||
| ## Technical Implementation | ||
|
|
||
| ### File Type Support | ||
| The new system supports comprehensive file categories: | ||
| - **Images**: PNG, JPG, JPEG, GIF, BMP, WEBP, SVG | ||
| - **Documents**: PDF, DOC, DOCX, TXT, RTF, ODT | ||
| - **Code Files**: JS, TS, PY, JAVA, CPP, HTML, CSS, JSON, XML, YAML | ||
| - **Data Files**: CSV, XLS, XLSX, SQL | ||
| - **Archives**: ZIP, RAR, TAR, GZ | ||
| - **And many more**: All file types with proper MIME detection | ||
|
|
||
| ## Testing Performed | ||
|
|
||
| - [x] UI Testing: Verified paperclip icon displays correctly | ||
| - [x] File Selection: Tested file dialog with various file types | ||
| - [x] Size Validation: Confirmed 10MB limit enforcement | ||
| - [x] MIME Detection: Verified correct file type categorization | ||
| - [x] Text File Handling: Tested content extraction for text files | ||
| - [x] Binary File Handling: Verified base64 encoding for binary files | ||
| - [x] Backward Compatibility: Confirmed existing image functionality unchanged | ||
| - [x] Translation Testing: Verified all language translations display correctly | ||
| - [x] Message Handling: Tested both selectImages and selectFiles workflows | ||
|
|
||
| ## Verification of Acceptance Criteria | ||
|
|
||
| - [x] File Dialog Enhancement: Now accepts all file types instead of images only | ||
| - [x] Icon Update: Camera icon replaced with paperclip icon | ||
| - [x] Functionality Preservation: All existing image attachment features work unchanged | ||
| - [x] User Experience: Seamless transition with improved file support | ||
| - [x] Error Handling: Proper validation and user feedback for file operations | ||
|
|
||
| ## Files Changed | ||
|
|
||
| - webview-ui/src/components/chat/ChatTextArea.tsx - Icon and prop updates | ||
| - webview-ui/src/components/chat/ChatView.tsx - File selection workflow | ||
| - src/integrations/misc/process-files.ts - New comprehensive file processing | ||
| - src/shared/WebviewMessage.ts - Added selectFiles message type | ||
| - src/shared/ExtensionMessage.ts - Added selectedFiles message type | ||
| - src/core/webview/webviewMessageHandler.ts - Dual message handling | ||
| - webview-ui/src/i18n/locales/*/chat.json - Translation updates (5 languages) | ||
|
|
||
| ## Potential Impacts | ||
|
|
||
| - **Breaking Changes**: None - full backward compatibility maintained | ||
| - **Performance**: Minimal impact - file processing only on user action | ||
| - **Security**: File size limits and type validation prevent abuse | ||
| - **Accessibility**: Improved with updated aria-labels and tooltips | ||
|
|
||
| The implementation maintains the existing codebase patterns while providing a robust, extensible file attachment system. |
