package:liquify v1.5.0

New Features

• Custom delimiters support - Configure alternative template delimiters via LiquidConfig
  • Use ERB-style (<% %>, <%= %>), bracket-style ([% %], [[ ]]), or any custom delimiters
  • Built-in presets: LiquidConfig.erb for ERB-style templates
  • Custom tags automatically support configured delimiters via createTagStart(), createTagEnd(), etc.
  • Parser caching ensures performance is not impacted when using multiple configurations

Performance Improvements

• 92-95% reduction in parser activations through comprehensive optimization:
  • Lookahead-based element routing (skips tag parsers for plain text)
  • Precedence-based expression parser (eliminates repeated prefix parsing)
  • Pattern-based text(), identifier(), and memberAccess() parsers
  • First-character routing in primaryTerm() (skips impossible alternatives)

Breaking Changes

• Custom tags using {{ }} syntax must now explicitly declare their delimiter type

  If you have a custom tag that uses variable-style delimiters ({{ mytag }}), you must now override delimiterType:

  class MyCustomTag with CustomTagParser {
    @override
    TagDelimiterType get delimiterType => TagDelimiterType.variable;
    
    @override
    Parser parser() {
      // ... your parser implementation
    }
  }

  Custom tags using standard {% %} syntax (the default) require no changes.

Internal Changes

• Add TagDelimiterType enum to distinguish custom tag delimiter styles
• Optimize parser routing based on delimiter lookahead
