# INSTALLATION

## From CPAN (when published)

    cpanm App::GHGen

## From Source

    git clone https://github.com/nigelhorne/ghgen.git
    cd ghgen
    cpanm --installdeps .
    perl Makefile.PL
    make
    make test
    make install

## Quick Install Script

    curl -L https://cpanmin.us | perl - App::GHGen

# QUICK START

The fastest way to get started:

    # Navigate to your project
    cd my-project/

    # Auto-detect and generate workflow
    ghgen generate --auto

    # Review the generated workflow
    cat .github/workflows/*-ci.yml

    # Commit and push
    git add .github/workflows/
    git commit -m "Add CI workflow"
    git push

That's it! GHGen will detect your project type and create an optimized workflow.

# WORKFLOW GENERATION

## Auto-Detection

GHGen can automatically detect your project type by scanning for indicator files:

    ghgen generate --auto

Detection looks for:

- **Perl**: cpanfile, dist.ini, Makefile.PL, Build.PL, lib/\*.pm
- **Node.js**: package.json, package-lock.json, yarn.lock
- **Python**: requirements.txt, setup.py, pyproject.toml
- **Rust**: Cargo.toml, Cargo.lock
- **Go**: go.mod, go.sum
- **Ruby**: Gemfile, Rakefile
- **Docker**: Dockerfile, docker-compose.yml

If multiple types are detected, it shows alternatives:

    ✓ Detected project type: PERL
      Evidence: cpanfile, lib, t

    Other possibilities:
      • docker (confidence: 65%)

# WORKFLOW ANALYSIS

## Basic Analysis

Scan all workflows in your repository for issues:

    ghgen analyze

    GitHub Actions Workflow Analyzer
    ==================================================

    📄 Analyzing: perl-ci.yml
      ⚠ No dependency caching found - increases build times
         💡 Fix:
         - uses: actions/cache@v5
           with:
             path: ~/perl5
             key: ${{ runner.os }}-${{ matrix.perl }}-${{ hashFiles('cpanfile') }}

      ⚠ Found 2 outdated action(s)
         💡 Fix:
         Update to latest versions:
           actions/cache@v4 → actions/cache@v5

    ==================================================
    Summary:
      Workflows analyzed: 1
      Total issues found: 2

The analyzer checks for:

- **Performance Issues**
    - - Missing dependency caching (npm, pip, cargo, go, bundler, cpanm)
    - - Jobs that could run in parallel
- **Security Issues**
    - - Unpinned action versions (@master, @main)
    - - Missing permissions declarations
    - - Overly broad permissions (contents: write when read is sufficient)
- **Cost Issues**
    - - Missing concurrency controls (wasted CI on superseded runs)
    - - Overly broad triggers (runs on every push without filters)
    - - Inefficient matrix strategies
- **Maintenance Issues**
    - - Outdated action versions (v4 → v5, v5 → v6)
    - - Outdated runner versions (ubuntu-18.04 → ubuntu-latest)

## Auto-Fix

Automatically apply fixes to your workflows:

    ghgen analyze --fix

    GitHub Actions Workflow Analyzer
    (Auto-fix mode enabled)
    ==================================================

    📄 Analyzing: perl-ci.yml
      ⚙ Applying 3 fix(es)...
      ✓ Applied 3 fix(es)

    ==================================================
    Summary:
      Workflows analyzed: 1
      Total issues found: 3
      Fixes applied: 3

Auto-fix can:

- **Add caching** - Detects project type and adds appropriate dependency caching
- **Update actions** - Updates to latest versions (cache@v4→v5, checkout@v5→v6, etc.)
- **Pin versions** - Converts @master/@main to specific version tags
- **Add permissions** - Adds `permissions: contents: read` for security
- **Add concurrency** - Adds concurrency groups to cancel superseded runs
- **Optimize triggers** - Adds branch and path filters
- **Update runners** - Changes ubuntu-18.04 to ubuntu-latest

The auto-fix feature is safe:

- Only fixes well-understood issues
- Preserves YAML structure and comments
- Changes are easily reviewable with `git diff`
- Can be reverted if needed

## Cost Estimation

See your current CI usage and potential savings:

    ghgen analyze --estimate

    GitHub Actions Workflow Analyzer
    (Cost estimation mode)
    ==================================================

    📊 Estimating current CI usage...

    Current Monthly Usage:
      Total CI minutes: 1,247
      Billable minutes: 0 (after 2,000 free tier)
      Estimated cost: $0.00

    Per-Workflow Breakdown:
      Perl CI      840 min/month (100 runs × 8.4 min/run)
      Node.js CI   300 min/month ( 60 runs × 5.0 min/run)
      Docker       107 min/month ( 20 runs × 5.4 min/run)

    📄 Analyzing: node-ci.yml
      ⚠ No dependency caching found
      ⚠ No concurrency group defined

    ==================================================
    Summary:
      Workflows analyzed: 3
      Total issues found: 2

    💰 Potential Savings:
      With recommended changes: 647 CI minutes/month
      Reduction: -600 minutes (48%)
      Cost savings: $4.80/month (for private repos)

      Breakdown:
        • Adding dependency caching: ~75 min/month
        • Adding concurrency controls: ~525 min/month

The cost estimator considers:

- Workflow trigger frequency (push, PR, schedule)
- Estimated duration per run (based on steps and commands)
- Matrix build multipliers (e.g., 3 OS × 8 Perl versions = 24 jobs)
- Parallel vs sequential job execution
- GitHub Actions pricing ($0.008/minute for private repos, 2000 free minutes/month)

# CONFIGURATION DETECTION

GHGen automatically detects configuration and adjusts workflows accordingly.

## Minimum Version Detection

For Perl, minimum version is detected from:

- cpanfile: `requires 'perl', '5.036'`
- Makefile.PL: `MIN_PERL_VERSION => '5.036'`
- dist.ini: `perl = 5.036`

Only compatible Perl versions are tested (e.g., if min is 5.36, won't test 5.32 or 5.34).

## Dependency Files

Caching is based on dependency files:

- Perl: cpanfile, dist.ini, Makefile.PL, Build.PL
- Node: package-lock.json, yarn.lock, pnpm-lock.yaml
- Python: requirements.txt, Pipfile.lock
- Rust: Cargo.lock
- Go: go.sum
- Ruby: Gemfile.lock

# BEST PRACTICES

## Workflow Generation

- **Use --auto for quick start** - Let GHGen detect your project
- **Use --customize for fine control** - Customize versions, OS, and features
- **Review before committing** - Always review generated workflows
- **Test locally first** - Use tools like `act` to test locally
- **Start with defaults** - Customize only when needed

## Workflow Analysis

- **Run analyze regularly** - Weekly `ghgen analyze` catches issues early
- **Use --estimate** - Monitor CI costs over time
- **Enable in CI** - Catch issues in PRs automatically
- **Review auto-fixes** - Always review changes before committing
- **Fix incrementally** - Don't fix everything at once if unsure

## Cost Optimization

- **Add caching** - Biggest time/cost savings
- **Add concurrency** - Cancel superseded runs
- **Filter triggers** - Only run on relevant changes
- **Optimize matrix** - Don't test unnecessary combinations
- **Run coverage once** - Only on one OS/version combination

# EXAMPLES

## Example 1: New Perl Module

    # In your new Perl module directory
    cd My-Module/

    # Create cpanfile
    echo "requires 'perl', '5.036';" > cpanfile

    # Auto-detect and generate
    ghgen generate --auto

    # Review and commit
    cat .github/workflows/perl-ci.yml
    git add .github/workflows/perl-ci.yml cpanfile
    git commit -m "Add CI workflow"
    git push

## Example 2: Optimize Existing Project

    # Clone project
    git clone https://github.com/user/project.git
    cd project/

    # Analyze with cost estimation
    ghgen analyze --estimate

    # Review suggestions, then fix
    ghgen analyze --fix

    # Review changes
    git diff .github/workflows/

    # Commit improvements
    git add .github/workflows/
    git commit -m "Optimize CI: add caching, update actions, add permissions"
    git push

## Example 3: Multi-Language Project

    # Project with both Node.js and Docker
    cd fullstack-app/

    # Generate Node.js workflow
    ghgen generate --type=node --output=.github/workflows/frontend-ci.yml

    # Generate Docker workflow
    ghgen generate --type=docker --output=.github/workflows/backend-build.yml

    # Analyze both
    ghgen analyze

## Example 4: Custom Perl Testing Matrix

    # Interactive customization
    ghgen generate --type=perl --customize

    # Choose:
    # Perl versions: 5.36, 5.38, 5.40 (skip older)
    # OS: Ubuntu, macOS (skip Windows if not needed)
    # Perl::Critic: Yes
    # Coverage: Yes
    # Branches: main

## Example 5: CI Quality Gate

Add workflow quality checks to your CI:

    # .github/workflows/ci-quality.yml
    name: CI Quality Check

    on:
      pull_request:
        paths:
          - '.github/workflows/**'

    jobs:
      check:
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v6
          - name: Install GHGen
            run: cpanm --notest App::GHGen
          - name: Check workflows
            run: |
              if ! ghgen analyze; then
                echo "::error::Workflow quality issues found"
                echo "Run 'ghgen analyze --fix' locally to fix"
                exit 1
              fi

# TROUBLESHOOTING

## Installation Issues

**Problem:** `cpanm` fails to install dependencies

**Solution:**

    # Install build tools first
    # On Debian/Ubuntu:
    sudo apt-get install build-essential

    # On macOS:
    xcode-select --install

    # Then retry
    cpanm App::GHGen

## Generation Issues

**Problem:** "No .github/workflows directory"

**Solution:**

    mkdir -p .github/workflows
    ghgen generate --auto

**Problem:** Auto-detect doesn't find my project type

**Solution:**

    # Specify type explicitly
    ghgen generate --type=perl

    # Or ensure indicator files exist
    touch cpanfile  # for Perl
    touch package.json  # for Node.js

## Analysis Issues

**Problem:** "Failed to parse YAML"

**Solution:**

    # Validate YAML syntax first
    yamllint .github/workflows/*.yml

    # Fix YAML errors, then retry
    ghgen analyze

**Problem:** Cost estimates seem wrong

**Solution:**

Cost estimates are approximations based on:

- Typical commit/PR frequency
- Average workflow duration
- Standard GitHub Actions pricing

Actual costs depend on your specific usage patterns.

## Auto-Fix Issues

**Problem:** Auto-fix didn't fix everything

**Solution:**

Some issues can't be auto-fixed:

- Complex workflow logic
- Custom actions
- Project-specific configurations

Review the remaining suggestions and apply manually.

## GitHub Action Issues

**Problem:** "Permission denied" errors

**Solution:**

    # Ensure correct permissions in workflow
    permissions:
      contents: write        # For auto-fix
      pull-requests: write   # For comments

**Problem:** Action not triggering

**Solution:**

    # For scheduled workflows, ensure:
    on:
      schedule:
        - cron: '0 9 * * 1'
      workflow_dispatch:  # Allows manual trigger

    # Test with manual trigger first
