Features

🎨 Comprehensive Syntax Highlighting

The extension provides highlighting for all Prism language features:

Token Types

Comments - Single-line with //
Strings - Regular and interpolated with ${expressions}
Numbers - Integers, decimals, scientific notation
Keywords - All 25+ keywords including uncertainty-specific ones
Operators - 40+ operators with special confidence operator highlighting
Functions - Built-in and user-defined functions

Confidence Operators

Special highlighting for Prism's unique confidence operators:

Operator	Description	Color Theme
`~>`	Confidence assignment	Cyan
`<~`	Confidence extraction	Cyan
`~~`	Confidence chaining	Green
`~\|\|>`	Parallel confidence	Purple
`~@>`	Threshold gate	Green
`~+`, `~-`, `~*`, `~/`	Confident arithmetic	Cyan
`~==`, `~!=`, `~<`, `~>`	Confident comparisons	Cyan
`~&&`, `~\|\|`	Confident logical	Cyan
`~??`	Confidence coalesce	Green
`~.`	Confident property access	Green

Semantic Highlighting

Uncertainty levels have semantic colors:

high - Green (success/proceed)
medium - Orange (caution)
low - Red (danger/stop)
default - Gray (fallback)

🌈 Custom Themes

Two themes optimized for Prism development:

Prism Dark

Based on Dracula with confidence-aware colors:

Dark background for reduced eye strain
High contrast for confidence operators
Clear distinction between regular and confidence operations

Prism Light

Based on GitHub theme with confidence-aware colors:

Light background for daytime coding
Subtle highlighting that doesn't distract
Professional appearance

To switch themes:

Press Cmd+K Cmd+T (Mac) or Ctrl+K Ctrl+T (Windows/Linux)
Select "Prism Dark" or "Prism Light"

⚙️ Language Configuration

Auto-closing pairs - Brackets, quotes, and parentheses
Bracket matching - Highlights matching brackets
Comment toggling - Cmd+/ to toggle comments
Smart indentation - Automatic indentation for blocks
Code folding - Collapse/expand code regions

Code Examples

Basic Syntax

// Variables and operations
name = "Prism"
version = 1.0
isAwesome = true

// Confidence operations
temperature = 72 ~> 0.95
humidity = 65 ~> 0.87

// String interpolation
message = "Welcome to ${name} v${version}!"

Uncertainty Control Flow

uncertain if (analysis) {
  high {        // Green highlighting
    deploy()
  }
  medium {      // Orange highlighting
    review()
  }
  low {         // Red highlighting
    abort()
  }
  default {     // Gray highlighting
    log_error()
  }
}

LLM Integration

// LLM calls with confidence
response = llm("Analyze security") ~> 0.9
summary = llm("Summarize: ${text}") ~> 0.85

// Confidence propagation
combined = response ~&& summary
fallback = response ~?? backup_analysis

Advanced Features

// Pipeline operations
result = data
  |> validate
  |> transform
  |> optimize

// Context blocks
in context Security {
  scan = analyze(code)
} shifting to Deployment {
  deploy(scan)
}

// Agent declarations
agents {
  analyzer: Agent { 
    confidence: 0.9,
    model: "claude"
  }
}

Configuration

File Associations

By default, the extension activates for .prism files. To add more file types:

Open VS Code settings (Cmd+,)
Search for "files.associations"
Add custom associations:

{
  "files.associations": {
    "*.prism": "prism",
    "*.prsm": "prism"
  }
}

Theme Customization

Override specific colors in your settings:

{
  "editor.tokenColorCustomizations": {
    "[Prism Dark]": {
      "textMateRules": [
        {
          "scope": "keyword.operator.confidence.arrow.prism",
          "settings": {
            "foreground": "#00ff00"
          }
        }
      ]
    }
  }
}

Tips and Tricks

1. Quick Theme Toggle

Create a keyboard shortcut for quick theme switching:

{
  "key": "cmd+shift+t",
  "command": "workbench.action.selectTheme"
}

2. Confidence Operator Snippets

Coming soon: Code snippets for common patterns:

unc → uncertain if (...) { high { } medium { } low { } }
conf → value ~> 0.9
llm → llm("${1:prompt}") ~> ${2:0.8}

3. Format on Save

Enable auto-formatting when Prism formatter is available:

{
  "[prism]": {
    "editor.formatOnSave": true
  }
}

Troubleshooting

Extension Not Working

Check file extension - Ensure files end with .prism
Reload window - Cmd+R or Ctrl+R in VS Code
Check installation - Run code --list-extensions | grep prism
Reinstall - Remove and reinstall the extension

Colors Look Wrong

Check theme - Ensure you're using Prism Dark/Light or a compatible theme
Disable other extensions - Some extensions may override colors
Reset settings - Remove custom token color customizations

Performance Issues

Large files - Syntax highlighting may be slow on very large files
Complex expressions - Deep nesting may impact performance
Other extensions - Disable unnecessary extensions
