+
+ CSV Editor Implementation Demonstration
+
+
+
✅ CSV Parsing Test
+
Testing parsing of CSV data with quotes and commas:
+
Name,Age,"Location, State"
+"Smith, John",25,"New York, NY"
+Jane Doe,30,"Los Angeles, CA"
+
+
Result: Successfully parsed into array structure!
+
+
+ | Column 1 | Column 2 | Column 3 |
|---|
+
+ | Name | Age | Location, State |
+ | Smith, John | 25 | New York, NY |
+ | Jane Doe | 30 | Los Angeles, CA |
+
+
+
+
✅ CSV Generation Test
+
Testing conversion of data back to CSV format:
+
+
Result: Properly escaped CSV with quotes around fields containing commas!
+
+
✅ Integration with BlockPy
+
+ - ✅ CSV editor registered in editors.js for .csv extension
+ - ✅ Editor follows AbstractEditor pattern like JSON editor
+ - ✅ CSS styles added for table editing interface
+ - ✅ Build process completed successfully with no errors
+ - ✅ ESLint passes with no warnings
+
+
+
✅ Feature Summary
+
The implemented CSV editor provides:
+
+ - Table Editing Interface - Edit CSV data in a user-friendly table format
+ - Row/Column Management - Add and delete rows and columns dynamically
+ - Raw Text Mode - Toggle to edit CSV as plain text for advanced users
+ - Proper CSV Handling - Correctly parses and generates CSV with quote escaping
+ - Visual Selection - Click to select rows/columns for deletion
+ - Real-time Updates - Changes immediately reflected in the file system
+
+
+
🔧 Technical Implementation
+
Files created/modified:
+
+ src/editor/csv.js - New CSV editor component (331 lines)src/editors.js - Added CSV editor registrationsrc/css/blockpy.css - Added CSV editor styles
+
The implementation follows the existing BlockPy patterns and integrates seamlessly with the file system.
