PowerShell AST Inspector

Inspect and visualize the Abstract Syntax Tree (AST) of PowerShell scripts with interactive tree view and detailed property examination.

Features

• 🔍 Analyze PowerShell Scripts - View the complete AST structure in an interactive tree view
• 📋 Inspect Node Properties - See detailed properties and metadata for each AST node
• 🎯 Highlight Code - Right-click any AST node to highlight the corresponding code in your editor
• 🕵️ Go to AST - Right-click your code and reveal the corresponding AST node in the tree view

Technical Details

The extension works by:

1. Reading PowerShell script content
2. Executing a PowerShell script that uses System.Management.Automation.Language.Parser
3. Converting the AST to JSON format
4. Displaying the structure in a VS Code tree view

The AST inspection provides information about:

• Node types (CommandAst, VariableExpressionAst, etc.)
• Source location (line and column numbers)
• Node relationships (parent-child hierarchy)
• Specific properties (command names, variable names, string values)

Development

This extension is open source and open to contributions. For development setup and building instructions, see CONTRIBUTING.md.
