Synergy DBL Language Server (Prototype)

A prototype Language Server Protocol (LSP) implementation for Synergy DBL, providing syntax highlighting and limited IntelliSense capabilities.

Current Status: MVP Prototype

This is a prototype implementation that uses regex-based parsing to provide basic language support. It is not a production-ready solution but serves as a proof of concept for Synergy DBL language support in IDEs supporting LSP.

Features

Syntax Highlighting

• Synergy DBL (.dbl) syntax highlighting
• Language configuration including:
  • Bracket matching
  • Comments
  • Indentation rules

XML Support

• .synproj file recognition and syntax highlighting

Experimental LSP IntelliSense

• Hover information for:
  • Record fields
  • Subroutine parameters
  • Labels
  • Common DBL keywords
• Basic code completion for:
  • Record names
  • Field names
  • Subroutine names
  • Labels
  • Keywords
• Simple goto definition support
• Basic reference finding

Limitations

• Uses regex-based parsing which may not catch all edge cases
• Limited semantic understanding of the code
• Basic IntelliSense features only
• May not handle all Synergy DBL language constructs correctly

Future Plans

The project plans to evolve beyond the MVP stage with the following improvements:

1. Tree-sitter Integration: Replace regex-based parsing with a proper parser using tree-sitter for more accurate syntax analysis
2. Enhanced Semantic Analysis: Better understanding of code structure and relationships
3. Improved IntelliSense: More accurate and comprehensive code completion and hover information
4. Better Error Detection: More reliable syntax and semantic error checking
5. Performance Optimization: Improved parsing and analysis speed

Installation

npm install
npm run compile

Usage

This language server can be used with any LSP-compatible editor. The following file extensions are configured by default:

• .dbl → Synergy DBL
• .synproj → XML

To associate additional file extensions with Synergy DBL, add the following to your editor settings:

{
  "files.associations": {
    "*.myext": "dbl"  // Add ".myext" extension to Synergy DBL
  }
}

Disclaimer

This is a prototype implementation and should not be used in production environments without thorough testing and validation. The current regex-based parsing may not handle all Synergy DBL language constructs correctly.
