Atom Editor, PHP CodeSniffer And Drupal Coding Standards

This way will help you keep watching Drupal coding standards while you're writing your code inside your Atom editor.

  // Make sure you have composer installed in your machine.
  // Then run this command.
  composer global require drupal/coder

// Add this line in ~/.bashrc file to make sure everytime you turn on your machine it will be executed.
export PATH="$PATH:$HOME/.composer/vendor/bin"

  // You can verify this has worked with:
  phpcs -i

  // Copy (Drupal) and (DrupalPractice) folders to (Standards) folder or just make a symbolic link.
  ln -s ~/.composer/vendor/drupal/coder/coder_sniffer/Drupal ~/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/Drupal
  ln -s ~/.composer/vendor/drupal/coder/coder_sniffer/DrupalPractice ~/.composer/vendor/squizlabs/php_codesniffer/CodeSniffer/Standards/DrupalPractice
