powershell-specter

This VS Code extension provides PowerShell Script Analysis using Specter

Features

• Full PowerShell language support via Specter LSP
• Real-time diagnostics and code analysis
• IntelliSense and code completion
• Navigation and refactoring support

Requirements

• VS Code 1.75.0 or higher
• PowerShell language server executable (Specter.Server.exe)

Installation

1. Build the extension:

   pnpm install
   pnpm build
   

2. Package the executable:

   • The extension expects the PowerShell language server at: dist/lspserver/Specter.Server.exe
   • Ensure Specter.Server.exe is built from the Specter project and placed in the correct location

3. Load the extension in VS Code:

   • Open the extension folder in VS Code
   • Press F5 to open an Extension Development Host window

How It Works

The extension:

1. Activates when you open PowerShell files (.ps1, .psd1, .psm1)
2. Spawns the Specter language server process with the lsp command
3. Communicates with the server via stdin/stdout
4. Provides diagnostics, completions, and other LSP features

Development

• Run pnpm build to compile the extension
• Run pnpm watch to rebuild on file changes
• Test by pressing F5 in VS Code to launch the Extension Development Host

Building the Language Server

The language server executable must be built separately from the Specter.Server project and placed at dist/lspserver/Specter.Server.exe.

See the Specter project for details on building the server.
