## CHANGES
- Add Save method to PatternsEntity struct
- Create pattern directory with proper permissions
- Write pattern content to system pattern file
- Add comprehensive test for Save functionality
- Verify directory creation and file contents
- Handle errors for directory and file operations
- Add new template package to handle variable substitution with {{variable}} syntax
- Move substitution logic from patterns to centralized template system
- Update patterns.go to use template package for variable processing
- Support special {{input}} handling for pattern content
- Update chatter.go and rest API to pass input parameter
- Enable multiple passes to handle nested variables
- Report errors for missing required variables
This change sets up a foundation for future templating features like front matter
and plugin support while keeping the substitution logic centralized.
- Stronger separation of concerns between chatter.go and patterns.go
- Consolidate pattern loading logic into GetPattern method
- Support both file and database patterns through single interface
- Maintain API compatibility with Storage interface
- Handle variable substitution in one place
- Keep backward compatibility for REST API through Get method
The changes enable cleaner pattern handling while maintaining
existing interfaces and adding file-based pattern support.
Allow patterns to be loaded directly from files using explicit path prefixes
(~/, ./, /, or \). This enables easier testing and iteration of patterns
without requiring installation into the fabric config structure.
- Supports relative paths (./pattern.txt, ../pattern.txt)
- Supports home directory expansion (~/patterns/test.txt)
- Supports absolute paths
- Maintains backwards compatibility with named patterns
- Requires explicit path markers to distinguish from pattern names
Example usage:
fabric --pattern ./draft-pattern.txt
fabric --pattern ~/patterns/my-pattern.txt
fabric --pattern ../../shared-patterns/test.txt
