PowerShell.MCP v1.2.9 - Text Deletion and Architecture Improvements

Text Deletion and Architecture Improvements

This release introduces text deletion capabilities through empty replacement strings and improves the module architecture with IModuleAssemblyInitializer.

✨ What's New

🗑️ Text Deletion with Empty Replacement

You can now delete text by using an empty string for the -Replacement parameter in Update-MatchInFile:

# Remove port numbers from configuration
Update-MatchInFile config.txt -Contains ":8080" -Replacement ""

# Delete all digits from a string
Update-MatchInFile data.txt -Pattern '\d+' -Replacement ""

# Clean up debug statements
Update-MatchInFile app.log -Contains "DEBUG " -Replacement ""

Key Benefits:

• Simple text removal without complex regex
• Works with both -Contains (literal) and -Pattern (regex) modes
• Preserves file encoding and newlines

---

🏗️ Architecture Refactoring

The module initialization has been modernized from CmdletProvider to IModuleAssemblyInitializer:

Benefits:

• Improved module loading performance
• Better PowerShell 7+ compatibility
• Cleaner initialization architecture
• Reduced memory footprint

Note: This is an internal change with no impact on cmdlet usage.

🗺️ Built-in Interactive Map Prompt

New MCP custom prompt that automatically creates interactive maps - no PowerShell.Map knowledge required:

Usage: Simply tell Claude what you want to see:

"Create a map of famous temples in Kyoto with PowerShell.Map module"
"Show me hot springs in Hakone area"
"Map popular ramen shops in Tokyo"

That's it! Claude automatically:

• Researches and validates locations
• Creates color-coded markers with emoji labels
• Displays the interactive map
• Offers an automated tour of all spots

Example Themes:

• Hot springs (♨️), Ramen shops (🍜), Tourist spots (temples⛩️, museums🏛️, parks🌳)

Key Benefits:

• No need to learn PowerShell.Map commands
• Automatic coordinate validation
• Beautiful emoji-enhanced maps
• Interactive tour feature
• Map opens automatically at http://localhost:8765/

💡 Usage Examples
