Development Environment

This template includes configuration for WordPress Environment (wp-env) to make local development easier:

1. Install Node.js dependencies:

   npm install
   

2. Start the WordPress environment:

   npm run start
   

3. For testing in different WordPress environments:

   # For single site testing
   npm run setup:single
   
   # For multisite testing
   npm run setup:multisite
   

   See Testing Framework for more details on our testing approach.

4. Access your local WordPress site at http://localhost:8888 (admin credentials: admin/password)

Testing

The template includes multiple testing approaches:

WordPress Playground Testing (No Docker Required)

Test your plugin directly in the browser without any local setup:

1. Single site testing: Open in WordPress Playground

2. Multisite testing: Open in WordPress Playground

For more details, see the Playground Testing documentation.

PHP Unit Tests

1. Install Composer dependencies:

   composer install
   

2. Run PHP unit tests:

   npm run test:php
   

3. Check PHP coding standards:

   npm run lint:php

Code Quality Tools

This project uses several automated code quality tools to ensure high standards.

These tools are free for public repositories and should be integrated into any new repositories based on this template:

1. CodeRabbit: AI-powered code review tool

   • Website
   • Provides automated feedback on pull requests

2. CodeFactor: Continuous code quality monitoring

   • Website
   • Provides a grade for your codebase

3. Codacy: Code quality and static analysis

   • Website
   • Identifies issues related to code style, security, and performance
   • Requires a CODACY_PROJECT_TOKEN secret in your GitHub repository settings
   • To set up Codacy:
     1. Go to Codacy and sign in with your GitHub account
     2. Add your repository to Codacy
     3. Go to your project settings > Integrations > Project API
     4. Generate a project API token
     5. Add the token as a secret named CODACY_PROJECT_TOKEN in your GitHub repository settings
     6. Note: Codacy tokens are project-specific, so they need to be added at the repository level. You can use GitHub Actions to securely pass tokens between repositories if needed.

4. SonarCloud: Code quality and security analysis

   • Website
   • Provides detailed analysis of code quality and security
   • Requires a SONAR_TOKEN secret in your GitHub repository settings
   • To set up SonarCloud:
     1. Go to SonarCloud and sign in with your GitHub account
     2. Create a new organization or use an existing one
     3. Add your repository to SonarCloud
     4. Generate a token in SonarCloud (Account > Security > Tokens)
     5. Add the token as a secret named SONAR_TOKEN in your GitHub repository or organization settings (see "GitHub Secrets Management" section below)

5. PHP_CodeSniffer (PHPCS): PHP code style checker

   • Enforces WordPress Coding Standards
   • Automatically runs in GitHub Actions workflow
   • Run locally with composer phpcs

6. PHP Code Beautifier and Fixer (PHPCBF): Automatically fixes coding standard violations

   • Run locally with composer phpcbf

7. PHPStan: PHP static analysis tool

   • Detects bugs and errors without running the code
   • Run locally with composer phpstan

8. PHP Mess Detector (PHPMD): Analyzes code for potential problems

   • Identifies complex code, unused parameters, etc.
   • Run locally with composer phpmd

For detailed setup instructions, see the Code Quality Setup Guide.

Using AI Assistants with Code Quality Tools

When you receive feedback from these code quality tools, you can use AI assistants to help address the issues:

1. Copy the output from the code quality tool
2. Paste it into your AI assistant chat
3. Request the AI's assistance to interpret and resolve the reported issues
4. Apply the suggested fixes
5. Commit the changes and verify that the issues are resolved

For more information on coding standards and how to pass code quality checks, see the Coding Standards Guide.

GitHub Secrets Management

GitHub offers three levels of secrets management, each with different scopes and use cases:

1. Organization Secrets (recommended for teams and organizations):

   • Available at: GitHub Organization > Settings > Secrets and variables > Actions
   • Scope: Can be shared across multiple repositories within the organization
   • Benefits: Centralized management, reduced duplication, easier rotation
   • Recommended for: SONAR_TOKEN and other tokens that apply to multiple repositories
   • Note: You can restrict which repositories can access organization secrets
   • Note: Codacy tokens (CODACY_PROJECT_TOKEN) are project-specific and should be set at the repository level

2. Repository Secrets:

   • Available at: Repository > Settings > Secrets and variables > Actions
   • Scope: Limited to a single repository
   • Benefits: Repository-specific, higher isolation
   • Recommended for: CODACY_PROJECT_TOKEN and other repository-specific credentials or tokens that shouldn't be shared

3. Environment Secrets:

   • Available at: Repository > Settings > Environments > (select environment) > Environment secrets
   • Scope: Limited to specific deployment environments (e.g., production, staging)
   • Benefits: Environment-specific, can have approval requirements
   • Recommended for: Deployment credentials that vary between environments

For code quality tools like SonarCloud, organization secrets are recommended if you have multiple repositories that use these tools.

This approach reduces management overhead and ensures consistent configuration across projects. For Codacy, since tokens are project-specific, they should be set at the repository level.

Local Environment Setup for Code Quality Tools

To run code quality tools locally before committing to GitHub:

1. Install dependencies:

   composer install
   

2. Run PHP CodeSniffer:

   composer phpcs
   

3. Fix coding standards automatically:

   composer phpcbf
   

4. Run PHPStan static analysis:

   composer phpstan
   

5. Run PHP Mess Detector:

   composer phpmd
   

6. Run all linters at once:

   composer lint
   

7. Set up environment variables for SonarCloud and Codacy:

   • For macOS/Linux:

     export SONAR_TOKEN=your_sonar_token
     export CODACY_PROJECT_TOKEN=your_codacy_token
     

   • For Windows (Command Prompt):

     set SONAR_TOKEN=your_sonar_token
     set CODACY_PROJECT_TOKEN=your_codacy_token
     

   • For Windows (PowerShell):

     $env:SONAR_TOKEN="your_sonar_token"
     $env:CODACY_PROJECT_TOKEN="your_codacy_token"
     

8. Create a .env file (alternative approach):

   # .env (already included in .gitignore to prevent committing secrets)
   SONAR_TOKEN=your_sonar_token
   CODACY_PROJECT_TOKEN=your_codacy_token
   

   Then load these variables:

   # Using a tool like dotenv
   source .env
   

9. Run SonarCloud locally:

   # Install SonarScanner
   npm install -g sonarqube-scanner
   
   # Run analysis
   sonar-scanner \
     -Dsonar.projectKey=your_project_key \
     -Dsonar.organization=your_organization \
     -Dsonar.sources=. \
     -Dsonar.host.url=https://sonarcloud.io \
     -Dsonar.login=$SONAR_TOKEN
   

10. Run Codacy locally:

    # Install Codacy CLI
    npm install -g codacy-coverage
    
    # Run analysis
    codacy-analysis-cli analyze --directory . --project-token $CODACY_PROJECT_TOKEN
    

For more detailed instructions, see the Code Quality Setup Guide.

By running these tools locally, you can identify and fix issues before pushing your code to GitHub, ensuring smoother CI/CD workflows.

Git Updater Integration

This template is designed to work seamlessly with the Git Updater plugin for updates from GitHub and Gitea. To ensure proper integration:

1. Required Headers: The plugin includes specific headers in the main plugin file that Git Updater uses to determine update sources and branches:

   * GitHub Plugin URI: wpallstars/wp-plugin-starter-template-for-ai-coding
   * GitHub Branch: main
   * Primary Branch: main
   * Release Branch: main
   * Release Asset: true
   * Gitea Plugin URI: https://gitea.wpallstars.com/wpallstars/wp-plugin-starter-template-for-ai-coding
   * Gitea Branch: main
   

2. Tagging Releases: When creating a new release, always tag it with the 'v' prefix (e.g., v0.1.2) to ensure GitHub Actions can create the proper release assets.

3. GitHub Actions: The repository includes a GitHub Actions workflow that automatically builds the plugin and creates a release with the .zip file when a new tag is pushed.

4. Update Source Selection: The template includes a feature that allows users to choose their preferred update source (WordPress.org, GitHub, or Gitea).

For more information on Git Updater integration, see the Git Updater Required Headers documentation.
