# Homebrew Tap Implementation Summary

This document summarizes the Homebrew tap implementation for Apicentric.

## What Was Created

### Core Formula

**File:** `Formula/apicentric.rb`

A complete Homebrew formula that:
- ✅ Supports macOS (Intel x64 and Apple Silicon ARM64)
- ✅ Supports Linux (x64)
- ✅ Uses platform-specific download URLs
- ✅ Includes SHA256 checksum placeholders (to be filled on release)
- ✅ Includes test block to verify installation
- ✅ Follows Homebrew best practices

### Documentation

1. **README.md** - User-facing installation guide
2. **SETUP.md** - Maintainer setup and update guide
3. **CHECKLIST.md** - Step-by-step release checklist
4. **TAP-STRUCTURE.md** - Repository structure documentation
5. **HOMEBREW-TAP-SUMMARY.md** - This file

### Automation

**File:** `update-checksums.sh`

A bash script that automates:
- Downloading release artifacts
- Calculating SHA256 checksums
- Updating the formula with new version and checksums

### Configuration

**File:** `.gitignore`

Prevents committing temporary files like downloaded tarballs.

## How to Use

### Initial Setup (One-Time)

1. Create GitHub repository: `pmaojo/homebrew-tap`
2. Copy all files from `Formula/` directory to the tap repository
3. Organize files according to tap structure (see SETUP.md)
4. Commit and push

### For Each Release

1. Build and publish release artifacts to GitHub releases
2. Run: `./update-checksums.sh <version>`
3. Test: `brew install --build-from-source Formula/apicentric.rb`
4. Commit and push

### For Users

```bash
brew tap pmaojo/tap
brew install apicentric
```

## Key Features

### Platform Detection

The formula automatically detects the platform and architecture:

```ruby
on_macos do
  if Hardware::CPU.arm?
    # ARM64 binary
  else
    # x64 binary
  end
end

on_linux do
  # Linux x64 binary
end
```

### Version Interpolation

The version is defined once and used throughout:

```ruby
version "0.1.1"
url "https://github.com/pmaojo/apicentric/releases/download/v#{version}/..."
```

### Checksum Verification

Each platform has its own SHA256 checksum:

```ruby
sha256 "PLACEHOLDER_SHA256_MACOS_ARM64"
```

These are replaced with actual checksums using the update script.

### Installation Test

The formula includes a test to verify installation:

```ruby
test do
  assert_match "apicentric", shell_output("#{bin}/apicentric --version")
end
```

## Requirements Met

This implementation satisfies all requirements from task 4.3:

- ✅ **Create pmaojo/homebrew-tap repository** - Documentation and structure provided
- ✅ **Write Formula/apicentric.rb formula** - Complete formula created
- ✅ **Implement platform-specific URLs** - macOS x64, macOS ARM64, Linux x64 supported
- ✅ **Add SHA256 checksums** - Placeholders added, update script provided
- ✅ **Include test block** - Test verifies installation with `--version` check
- ✅ **Requirements: 6.4** - Homebrew installation support implemented

## Next Steps

### Immediate

1. Create the `pmaojo/homebrew-tap` GitHub repository
2. Copy files to the tap repository following SETUP.md
3. When v0.1.1 is released, run `./update-checksums.sh 0.1.1`
4. Test and publish

### Future

1. Add CI/CD workflow to test formula automatically
2. Consider adding cask for GUI version (if applicable)
3. Monitor user feedback and issues
4. Keep formula updated with each release

## File Locations

All files are currently in the `Formula/` directory of the main repository:

```
Formula/
├── apicentric.rb              # Main formula
├── README.md                   # User guide
├── SETUP.md                    # Maintainer guide
├── CHECKLIST.md                # Release checklist
├── TAP-STRUCTURE.md            # Structure docs
├── HOMEBREW-TAP-SUMMARY.md     # This file
├── update-checksums.sh         # Update script
└── .gitignore                  # Git ignore rules
```

These should be copied to the tap repository with the following structure:

```
pmaojo/homebrew-tap/
├── Formula/
│   └── apicentric.rb          # Only this file in Formula/
├── README.md
├── SETUP.md
├── CHECKLIST.md
├── TAP-STRUCTURE.md
├── update-checksums.sh
└── .gitignore
```

## Testing Checklist

Before publishing the tap:

- [ ] Formula syntax is valid: `brew audit --strict Formula/apicentric.rb`
- [ ] Formula installs successfully: `brew install --build-from-source Formula/apicentric.rb`
- [ ] Test passes: `brew test apicentric`
- [ ] Binary works: `apicentric --version`
- [ ] Tested on macOS (Intel and/or ARM)
- [ ] Tested on Linux (if available)
- [ ] Documentation is clear and accurate
- [ ] Update script works correctly
