use Magento\Framework\Setup\InstallDataInterface;

class InstallData implements InstallDataInterface
{
  private $eavSetupFactory;

  public function __construct(EavSetupFactory $eavSetupFactory)
  {
    $this->eavSetupFactory = $eavSetupFactory;
  }

  public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
  {
    $setup->startSetup();

  $installer->addAttribute('catalog_product', 'productattribute_example', [
    'group' => 'General',
    'label' => 'Attribute Example',
    'input' => 'text',
    'type' => 'varchar',
    'required' => 0,
    'visible_on_front' => 1,
    'filterable' => 0,
    'searchable' => 0,
    'comparable' => 0,
    'user_defined' => 1,
    'is_configurable' => 0,
    'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
    'note' => ''
  ]);
  $installer->endSetup();
}

Magento 2 Open Source (2014 onward)


public function creatingProductAttribute()
{
  $installer = $this->_installer;
  $attribute = $this->_attribute;
  $attributeRepository = $this->_attributeRepository;
  $indexAdmin = 0;
  $indexEnglish = 12;
  $attributes_meta = [
    'Finish' => [
      'type' => 'swatch_visual',
      'visible' => true,
      'options' => [
        'Option 1',
        'Option 2'
      ]
    ]
  ];

  foreach ($attributes_meta as $attribute_label => $attribute_meta) {
    $attribute_type = empty($attribute_meta['type']) ? 'text' : $attribute_meta['type'];
    $attribute_data = [
      'entity_type_id' => $installer->getEntityTypeId('catalog_product'),
      'attribute_code' => 'extension_attribute',
      'backend_type' => 'int',
      'frontend_input' => 'swatch_' === substr($attribute_type, 0, strlen('swatch_')) ? 'select' : $attribute_type,
      'frontend_label' => [$attribute_label],
      'is_required' => 0,
      'is_user_defined' => 1,
      'is_unique' => 0,
      'is_global' => 1,
      'is_visible' => 1,
      'is_searchable' => 0,
      'is_filterable' => 0,
      'is_comparable' => 0,
      'is_visible_on_front' => 0,
      'is_visible_in_advanced_search' => 1,
      'is_required_in_admin_store' => 0,
      'is_used_in_grid' => 1,
      'is_visible_in_grid' => 1,
      'is_filterable_in_grid' => 1
    ];

    $attribute->setData($attribute_data);
    $attribute->save();
    $installer->addAttributeToGroup('catalog_product', 'Default', 'General', $attribute->getId());
