🤖 MCP Server (AI-Powered Configuration)

Want to create Oh My Posh configurations using natural language with AI assistants? The Oh My Posh Configurator includes a Model Context Protocol (MCP) server that works with VS Code and GitHub Copilot.

Quick Setup for VS Code:

1. Add to your workspace .vscode/mcp.json:

   {
     "servers": {
       "ohmyposh-configurator": {
         "type": "stdio",
         "command": "node",
         "args": ["/path/to/ohmyposh-configurator/dist/mcp/index.js"]
       }
     }
   }
   

2. Build the MCP server:

   npm run build:mcp
   

3. Open GitHub Copilot Chat in VS Code and start creating prompts with AI!

Example Requests:

• "Create me a developer prompt with git and Python"
• "Add caching to all language segments"
• "Apply the Dracula color theme"

# Zsh
eval "$(oh-my-posh init zsh --config ~/your-theme.json)"

🛠️ Technology Stack

• ⚛️ Framework: React 19 with TypeScript
• ⚡ Build Tool: Vite 6.4
• 🎨 Styling: Tailwind CSS 4.1
• 🖱️ Drag & Drop: @dnd-kit (sortable lists and cross-container support)
• 💾 State Management: Zustand with localStorage persistence
• 🎯 Icons: Custom Nerd Font icon library (200+ icons) with unique IDs
• 📝 Config Parsing: js-yaml, @iarna/toml
• 📦 Data Loading: Dynamic JSON-based lazy loading with request-deduplication and caching

⚡ Performance & Optimization

• JSON Minification: All JSON metadata and configuration files are automatically minified during the production build to reduce payload size.
• Smart Caching: The application implements a request-deduplication and caching layer for all JSON assets. Each file is fetched exactly once, even if requested by multiple components simultaneously.
• Lazy Loading: Segment metadata is loaded on-demand by category, keeping the initial bundle size small.

Adding New Segments

Segments are now stored in separate JSON files by category in public/segments/. This makes it easy to add or modify segments without touching the codebase:

1. Open the appropriate category file (e.g., public/segments/languages.json)
2. Add your segment with the following structure:

   {
     "type": "segment-type",
     "name": "Display Name",
     "description": "Brief description",
     "icon": "lang-python",
     "defaultTemplate": " {{ .Property }} ",
     "properties": [
       {
         "name": ".Property",
         "type": "string",
         "description": "Description of this template variable"
       }
     ],
     "options": [
       {
         "name": "option_name",
         "type": "boolean",
         "default": true,
         "description": "What this option does"
       }
     ],
     "defaultCache": {
       "duration": "168h",
       "strategy": "folder"
     }
   }
   

3. Properties are template variables available in {{ }} templates (e.g., .Full, .Path)
4. Options are segment configuration settings (e.g., home_enabled, fetch_version)
5. defaultCache (optional) provides recommended caching for performance (see Cache Strategy Guide in public/segments/README.md)
6. Segments are loaded dynamically on demand for better performance
7. Colors are applied automatically from category-based color schemes

See public/segments/README.md for detailed instructions.
