D11 compatibility of show email address

Hi,
I have fixed all the Drupal 11 compatibility issues and created MR!2.
Kindly review it.
Thanks!

MR2 is working fine in both d10 and d11

Here's a patch that is identical to MR2, but it will work on the 1.2 release (so you don't have to load the dev version--which ironically is currently the same as v1.2).

Patch #8 is working fine with Drupal 11

Drupal 11 compatibility note:

The current version of show_email uses user_role_names(), which was deprecated in Drupal 10.2 and removed in Drupal 11.

For projects upgrading to Drupal 11, we replaced the module with a lightweight custom Field Formatter that provides similar functionality without deprecated APIs.

Key changes:
- Removed user_role_names()
- Used Role::loadMultiple() instead
- Avoided procedural user_load_* functions
- Relied on $items->getEntity() for performance
- Added proper cache context (user.roles)

Below is a Drupal 11 compatible formatter implementation:

<?php

namespace Drupal\show_email\Plugin\Field\FieldFormatter;

use Drupal\Core\Field\FieldDefinitionInterface;
use Drupal\Core\Field\FormatterBase;
use Drupal\Core\Form\FormStateInterface;
use Drupal\Core\Field\FieldItemListInterface;
use Drupal\user\Entity\Role;

/**
 * Plugin implementation of the 'show_email_address' formatter.
 *
 * @FieldFormatter(
 *   id = "show_email_address",
 *   label = @Translation("Show email address"),
 *   field_types = {
 *     "email"
 *   }
 * )
 */
class ShowEmailAddress extends FormatterBase {

  /**
   * {@inheritdoc}
   */
  public static function defaultSettings() {
    return [
      'hide_user_one' => TRUE,
      'hide_per_role' => [],
      'email_mailto' => FALSE,
    ] + parent::defaultSettings();
  }

  /**
   * {@inheritdoc}
   */
  public function settingsSummary() {
    $summary = [];

    $summary[] = $this->getSetting('hide_user_one')
      ? $this->t('User 1 is hidden.')
      : $this->t('User 1 is visible.');

    $summary[] = $this->getSetting('email_mailto')
      ? $this->t('Mailto link enabled.')
      : $this->t('Plain text email.');

    return $summary;
  }

  /**
   * {@inheritdoc}
   */
  public function settingsForm(array $form, FormStateInterface $form_state) {
    $elements = parent::settingsForm($form, $form_state);

    // Drupal 11 compatible role loading.
    $roles = Role::loadMultiple();
    $role_options = [];

    foreach ($roles as $role) {
      $role_options[$role->id()] = $role->label();
    }

    $elements['hide_user_one'] = [
      '#type' => 'checkbox',
      '#title' => $this->t('Hide User 1'),
      '#default_value' => $this->getSetting('hide_user_one'),
    ];

    $elements['hide_per_role'] = [
      '#type' => 'checkboxes',
      '#title' => $this->t('Hide per role'),
      '#options' => $role_options,
      '#default_value' => $this->getSetting('hide_per_role'),
    ];

    $elements['email_mailto'] = [
      '#type' => 'checkbox',
      '#title' => $this->t('Enable mailto link'),
      '#default_value' => $this->getSetting('email_mailto'),
    ];

    return $elements;
  }

  /**
   * {@inheritdoc}
   */
  public function viewElements(FieldItemListInterface $items, $langcode) {
    $elements = [];

    // Formatter applies to user entity.
    $user = $items->getEntity();

    // Hide User 1 if enabled.
    if ($this->getSetting('hide_user_one') && $user->id() == 1) {
      return $elements;
    }

    // Hide based on role.
    $roles_to_hide = array_filter($this->getSetting('hide_per_role'));
    if (!empty(array_intersect($roles_to_hide, $user->getRoles()))) {
      return $elements;
    }

    foreach ($items as $delta => $item) {
      $email = $item->value;

      $elements[$delta] = [
        '#type' => 'markup',
        '#markup' => $this->getSetting('email_mailto')
          ? '<a href="mailto:' . $email . '">' . $email . '</a>'
          : $email,
        '#cache' => [
          'contexts' => ['user.roles'],
        ],
      ];
    }

    return $elements;
  }

}

During Drupal 11 upgrade, we removed deprecated procedural functions (user_role_names(), user_load_by_mail()), eliminated unnecessary .module and schema files, simplified role filtering logic, and modernized the formatter to use entity-based APIs and proper cache contexts.

Fixed in 3.0.0. Supports Drupal 10 and 11.

To upgrade: composer require 'drupal/show_email:^3.0'

Thanks, everyone, for your contributions.
