[Copilot]

Implementation Plan for relteX CLI Tool

• Set up project structure and dependencies
  • Create go.mod with required dependencies
  • Create main.go entry point
  • Create .gitignore file
  • Create LICENSE file
• Implement core packages
  • Create internal/config package (config.go)
  • Create internal/registry package (registry.go, fetcher.go)
  • Create internal/component package (installer.go)
  • Create internal/utils package (files.go)
• Implement CLI commands
  • Create cmd/root.go with Cobra setup
  • Create cmd/init.go for project initialization
  • Create cmd/add.go for adding components
  • Create cmd/list.go for listing components
  • Create cmd/diff.go for comparing components
• Create documentation and CI/CD
  • Write comprehensive README.md
  • Create GitHub Actions release workflow
• Test and validate
  • Build the project
  • Test all commands manually
  • Verify error handling

Original prompt

Build Complete relteX CLI Tool in Go

Create a fully functional CLI tool in Go to help developers easily add and manage relteX-UI components in their React Native projects.

Context

relteX-UI is a React Native UI library (similar to shadcn/ui for React) with 35+ components. The registry is located at:

• Registry JSON: https://raw.githubusercontent.com/relteX-UI/relteX/main/registry.json
• Component files: https://github.com/relteX-UI/relteX/tree/main/registry/

Detailed Implementation Requirements

1. Main Entry Point (main.go)

package main

import (
	"github.com/relteX-UI/relteX-cli/cmd"
)

func main() {
	cmd.Execute()
}

2. Go Module (go.mod)

module github.com/relteX-UI/relteX-cli

go 1.21

require (
	github.com/briandowns/spinner v1.23.0
	github.com/fatih/color v1.16.0
	github.com/olekukonko/tablewriter v0.0.5
	github.com/spf13/cobra v1.8.0
	github.com/spf13/viper v1.18.2
)

3. Root Command (cmd/root.go)

• Set up Cobra CLI framework
• Version: 1.0.0
• Global flags: --verbose, --config
• Initialize Viper for configuration management
• Handle config file loading from reltex.json

4. Init Command (cmd/init.go)

Command: reltex init

Functionality:

• Check if package.json exists (validate React Native project)
• Create reltex.json with default configuration:

  {
    "registry": "https://raw.githubusercontent.com/relteX-UI/relteX/main/registry.json",
    "componentsDir": "./components/ui",
    "utils": "./lib/utils.ts",
    "style": "default"
  }

• Create components directory (./components/ui)
• Create lib directory
• Create utils.ts file with cn helper function:

  import { clsx, type ClassValue } from "clsx";
  import { twMerge } from "tailwind-merge";
  
  export function cn(...inputs: ClassValue[]) {
    return twMerge(clsx(inputs));
  }

• Display success message with next steps
• Use colored output (green for success, cyan for info)

5. Add Command (cmd/add.go)

Command: reltex add <component...> or reltex add --all

Functionality:

• Load configuration from reltex.json
• Support multiple component names as arguments
• Support --all flag to install all components
• For each component:
  1. Fetch registry from configured URL
  2. Find component in registry by name
  3. Install registry dependencies first (recursive)
  4. Download component files from GitHub raw URLs
  5. Save to configured components directory
  6. Parse and install npm dependencies
  7. Show progress with spinner
  8. Display success/failure for each component
• Handle errors gracefully
• Skip react-native from dependencies (already installed)
• Use npm or yarn (detect which is available)

Example URLs:

• Registry: https://raw.githubusercontent.com/relteX-UI/relteX/main/registry.json
• Component file: https://raw.githubusercontent.com/relteX-UI/relteX/main/registry/button/button.tsx

6. List Command (cmd/list.go)

Command: reltex list

Functionality:

• Fetch registry from configured URL (or default if no config)
• Display all components in a formatted table with:
  • Name
  • Description (truncated to 40 chars)
  • Dependencies count
  • Status (Installed/Available)
• Check which components are already installed locally
• Use tablewriter for nice formatting
• Use colors: cyan for headers, green for installed components
• Show total count

7. Diff Command (cmd/diff.go)

Command: reltex diff <component>

Functionality:

• Load configuration
• Check if component exists locally
• Fetch latest version from registry
• Compare file hashes (SHA256)
• Display if component is up-to-date or has updates
• Suggest update command if different
• Use colors: green for up-to-date, yellow for updates available

8. Config Package (internal/config/config.go)

type Config struct {
	Registry      string `json:"registry"`
	ComponentsDir string `json:"componentsDir"`
	Utils         string `json:"utils"`
	Style         string `json:"style"`
}

Functions:

• LoadConfig() - Load from reltex.json
• Save() - Save config to file
• Handle JSON marshaling/unmarshaling
• Error handling for missing files

9. Registry Package (internal/registry/registry.go)

type Component struct {
	Name                 string         `json:"name"`
	Type                 string         `json:"type"`
	Title                string         `json:"title"`
	Description          string         `json:"description"`
	Files                []RegistryFile `json:"files"`
	Dependencies  ...
