DynLex Language Support

Language support for the DynLex programming language in Visual Studio Code.

Features

• Syntax Highlighting: Server-driven semantic highlighting for DynLex code
• Diagnostics: Real-time error and warning reporting as you type
• Go to Definition: Navigate to variable and pattern definitions (F12 or Ctrl+Click)
• Incremental Sync: Efficient document synchronization on every keystroke

Requirements

• The dynlex compiler must be installed and accessible
• By default, the extension prefers a workspace build/dynlex, then a bundled binary, then dynlex on PATH

Extension Settings

This extension contributes the following settings:

• dynlex.server.port: Port for the DynLex language server (default: 5007)
• dynlex.server.path: Custom path to the dynlex executable (leave empty to use the default resolution)
• dynlex.server.flags: Additional flags passed to the DynLex language server process
• dynlex.server.useExternal: Connect to an already-running DynLex language server instead of spawning one

Commands

• DynLex: Restart Language Server: Restart the language server if it becomes unresponsive

Token Types

The extension provides semantic highlighting for the following token types:

• function - Function patterns
• section - Section patterns
• variable - Variables (with definition modifier for definitions)
• comment - Comments
• patternDefinition - Pattern definitions (with definition modifier)
• number - Numeric literals
• string - String literals
• intrinsic - Built-in intrinsic functions
• type - Type references
• keyword - Language keywords

Troubleshooting

If the language server fails to start:

1. Check the Output panel (View > Output) and select "DynLex Language Server"
2. Verify that dynlex is built and accessible at the configured path
3. Ensure the configured DynLex server port is available when using TCP mode
