Nov 1, 2025Monthly summary for 2025-11 (Checkmk/checkmk-docs): Key features delivered: - Code block escaping and character handling: improved escaping for hash, dollar, and plus signs in code blocks and during parsing, reducing rendering/parsing errors. - File type handling improvements: explicit Apache and Bash file type annotations and broader language type specification (bash, yaml, python, ini) to improve syntax recognition and processing. - File handling and block management: enhanced file handling and unspecific file block handling for more robust parsing. - Rendering and presentation: code blocks rendered as HTML to prevent rendering errors; collapsible structures and improved three-column table formatting for readability; shell prompt macros inserted to blocks; JSON file type macros supported. - Macro and hints consistency: CMK macro usage enforcement in guihints and UI hints to standardize macro usage; content-sync translations initialized for monitoring_oracle and update_major tasks. Major bugs fixed: - PowerShell substitutions fixed as part of command/code parsing. - Correct file types for code blocks (bash, python, bat) to ensure proper processing and highlighting. - Prompts after cd commands corrected to preserve context. - Bash and BAT blocks: corrected file type assignments to prevent misclassification. - Code block rendering and syntax highlighting fixes, including escaping problematic brackets and HTML rendering corrections. - Redundant code block specification cleaned up; prompt handling inside code blocks corrected; additional QA edge-cases for code blocks addressed. Overall impact and accomplishments: - Increased accuracy and reliability of doc rendering and code block processing, reducing manual fixes and support load. - Improved developer experience through consistent macro usage, clearer content presentation, and better translation initialization for future localization efforts. - Strengthened maintainability with explicit file-type annotations and robust parsing rules across multiple languages. Technologies/skills demonstrated: - Advanced parsing and escaping logic for code blocks; language-aware file type detection (Bash, Apache, YAML, Python, Ini, JSON). - HTML-based rendering strategies and syntax highlighting fixes; UI/UX enhancements (collapsible sections, improved tables). - Macro system usage (CMK macros) and guihints standardization; content-sync automation and translation workflows; code-review status tracking (KNW-1968/1661).
