Codemetry

Configuration Overview

Codemetry is designed to work out of the box with sensible defaults. Configuration is optional but allows fine-tuning for your specific workflow.

Configuration Files

Publishing the Config File

Terminal window
php artisan vendor:publish --tag=codemetry-config

This creates config/codemetry.php in your Laravel project.

Configuration Options

Analysis Window

'baseline_days' => 56,  // Days of history for baseline comparison
'follow_up_horizon_days' => 3,  // Days to scan for follow-up fixes

baseline_days determines how much history is used to establish “normal” patterns:

  • Default 56 days (8 weeks) provides stable baselines
  • Shorter periods are more reactive to recent changes
  • Longer periods are more stable but slower to adapt

follow_up_horizon_days controls how far ahead to look for fix commits:

  • Default 3 days catches most immediate fixes
  • Increase if your team’s fix cycle is longer
  • Shorter values may miss delayed fixes

Keyword Patterns

'keywords' => [
    'fix_pattern' => '/\b(fix|bug|hotfix|patch|typo|oops)\b/i',
    'revert_pattern' => '/\b(revert)\b/i',
    'wip_pattern' => '/\b(wip|tmp|debug|hack)\b/i',
],

These regex patterns identify commit types:

  • Fix pattern: Commits that fix issues
  • Revert pattern: Commits that undo changes
  • WIP pattern: Work-in-progress or temporary commits

See Keywords Configuration for customization details.

AI Configuration

'ai' => [
    'enabled' => false,  // AI is opt-in
    'engine' => env('CODEMETRY_AI_ENGINE', 'openai'),
    'api_key' => env('CODEMETRY_AI_API_KEY', null),
    'model' => env('CODEMETRY_AI_MODEL', null),  // null = use engine default
    'base_url' => env('CODEMETRY_AI_BASE_URL', null),  // Custom API endpoint
    'timeout' => env('CODEMETRY_AI_TIMEOUT', 30),  // Request timeout in seconds
    'batch_size' => env('CODEMETRY_AI_BATCH_SIZE', 10),  // Days per API call
],

AI summarization is disabled by default. To enable:

  1. Set enabled to true or use --ai=1 flag
  2. Configure your preferred engine
  3. Provide API credentials via environment variables

Advanced options:

  • base_url: Custom API endpoint for self-hosted models or proxies
  • timeout: Request timeout in seconds (default: 30)
  • batch_size: Number of days to process per API call (default: 10). Higher values mean fewer API calls but larger requests.

See AI Engines for setup instructions.

Environment Variables

Codemetry respects these environment variables:

ANTHROPIC_API_KEYAnthropic API key (fallback)—
DEEPSEEK_API_KEYDeepSeek API key (fallback)—
GOOGLE_AI_API_KEYGoogle AI API key (fallback)—

CLI Overrides

Most configuration options can be overridden via CLI flags:

Terminal window
# Override baseline period
php artisan codemetry:analyze --days=7 --baseline-days=30


# Override follow-up horizon
php artisan codemetry:analyze --days=7 --follow-up-horizon=5


# Enable AI for single run
php artisan codemetry:analyze --days=7 --ai=1


# Specify AI engine
php artisan codemetry:analyze --days=7 --ai=1 --ai-engine=anthropic

For most projects, the defaults work well. Consider adjusting:

  1. baseline_days: Increase to 90 for very stable projects, decrease to 30 for fast-moving projects
  2. follow_up_horizon_days: Increase to 5-7 if your team typically fixes issues later in the week
  3. Keywords: Customize if your team uses different conventions
// Example: Fast-moving startup project
return [
    'baseline_days' => 30,
    'follow_up_horizon_days' => 5,
    'keywords' => [
        'fix_pattern' => '/\b(fix|bug|hotfix|patch|typo|oops|broken)\b/i',
        'revert_pattern' => '/\b(revert|rollback)\b/i',
        'wip_pattern' => '/\b(wip|tmp|debug|hack|todo)\b/i',
    ],
];
