v2.0.0-preview

[2.0.0-preview] - 2025-01-14

Changed

• BREAKING: ASON 2.0 Support - Extension now uses ASON 2.0 format
• Configuration Options Updated:
  • ❌ Removed ason.useDictionary setting (no longer exists in ASON 2.0)
  • ✅ Added ason.useSections - Enable @section organization for objects (default: true)
  • ✅ Added ason.useTabular - Enable key:[N]{fields} tabular arrays (default: true)
  • Changed default ason.delimiter from "," to "|" (pipe is more token-efficient)
• Syntax Updates:
  • Compressed output now uses users:[2]{id,name} instead of users:[2]@id,name
  • Tabular data uses pipe delimiter | by default: 1|Alice|25 instead of 1,Alice,25
  • References use $var semantic names
  • Sections use @section for objects
• TypeScript Interface Updates:
  • AsonConfig interface updated with new options
  • SmartCompressor now called with correct ASON 2.0 options
• MCP Server Integration:
  • Environment variables updated: ASON_USE_SECTIONS, ASON_USE_TABULAR (replacing ASON_USE_DICTIONARY)
  • MCP provider passes correct options to latest @ason-format/mcp-server
• Updated Documentation:
  • README.md updated with ASON 2.0 syntax examples
  • Configuration table updated with new settings
  • All code examples show correct pipe-delimited output

Dependencies

• Updated @ason-format/ason to ^2.0.0-preview (from ^1.1.2)

Migration Notes

• User Settings: If you have custom ASON settings in VS Code:
  • Remove or rename "ason.useDictionary" → Not needed (enabled by default via sections/tabular)
  • Consider changing "ason.delimiter": "," → "|" for better token efficiency
• MCP Configuration: Auto-configured MCP servers will use new options automatically
• Output Format: Compressed ASON will look different but is 100% lossless and more token-efficient
