Regex patterns for config file updates use type-specific templates for bool, int, float, str, Optional, and List parameters. This Skill provides pre-built patterns and substitution guidance using re.sub to safely match and replace configuration values in BobConfig.py while preserving file structure and formatting.

Type-specific regex patterns handle boolean flags, integer values, floating-point numbers, strings, optional parameters, and list objects. Each pattern accounts for Python syntax, spacing, and type casting requirements to ensure re.sub substitutions update BobConfig.py correctly without breaking syntax or introducing formatting errors.

Test patterns using Python REPL with sample config content and re.sub calls to verify matches and replacements work as expected. The Skill includes guidance on using regex101 for pattern validation and troubleshooting edge cases before deploying save logic to config_manager.py.

Regex matching issues in config saves typically stem from incorrect spacing, type-casting syntax, or pattern escaping in re.sub calls. This Skill provides troubleshooting guidance on pattern structure, common pitfalls with optional and list types, and how to validate patterns against actual BobConfig.py content.

Yes. The pattern templates and structure guidance support creating save logic for new configuration parameters of any supported type. Apply the same type-specific regex approach and testing workflow to generate patterns that handle new bool, int, float, str, Optional, or List parameters in BobConfig.py.

Understanding Python regex syntax, re.sub substitution mechanics, and escape sequences is prerequisite knowledge. The Skill assumes familiarity with regex fundamentals and provides pattern templates and edge-case guidance rather than regex tutorials, making it suitable for developers with intermediate regex experience.
