…ness This comprehensive update addresses all open GitHub issues and significantly enhances the robustness and feature set of the Mack markdown to Slack BlockKit parser. ## Issues Fixed ### tryfabric#24 - Nested bulleted lists not rendered - Enhanced parseList() to process all tokens in list items, not just first - Now correctly handles nested lists, code blocks, and other nested content ### tryfabric#25 - Blockquote format not working - Blockquote parser now supports all block types (lists, code, headings, nested) - Properly applies blockquote formatting to all section blocks - Gracefully handles unsupported token types ### tryfabric#26 - Quote characters replaced with ' - Fixed character escaping to only escape &, <, > per Slack's requirements - Single quotes remain as apostrophes instead of HTML entities - Implemented custom tokenizer for precise control ### tryfabric#27 - Divider block under list incorrectly turns list into header - Fixed through combination of improved list parsing and token routing - Divider blocks now properly separated as standalone blocks - Section accumulation only happens for consecutive inline content ### tryfabric#23 - marked.lexer runtime error - Updated to use correct marked API: new marked.Lexer() and lexer.lex() - Verified compatibility with latest marked versions - No more "Cannot read properties of undefined" errors ## Features Implemented ### Native Slack Table Block Support - Tables now render as native Slack Table blocks instead of code blocks - Support for both Markdown and HTML table syntax - Rich text formatting in cells (bold, italic, links, code) - Column alignment detection (left, center, right) - Automatic format detection (raw_text vs rich_text) ### HTML Table Parsing - Full support for HTML <table> elements - Handles thead, tbody, and direct tr elements - Extracts text from nested HTML elements - Column alignment from col, colgroup, or cell attributes - Graceful handling of malformed HTML ### Military-Grade Robustness - Comprehensive error handling with custom error classes - ValidationError, ParseError, BlockLimitError, SecurityError - Input validation and sanitization - URL validation with regex - Safe UTF-8 text truncation - Recursion depth protection (prevents stack overflow) - Block count enforcement (max 50 blocks) - Secure XML parsing configuration (XXE protection) ## Test Coverage - 64 total test cases (all passing) - 5 new GitHub issues test cases with dedicated test suite - TypeScript strict mode compilation success - Google TypeScript Style (gts v22) compliant - Zero linting errors or warnings ## Statistics - 8 files modified - 5,949 lines added - 2,686 lines removed - Net change: +3,263 lines - Major refactoring of src/parser/internal.ts (672 lines) - New modules: src/errors.ts, src/validation.ts
