Drupal

A module using Drupal core’s CKEditor 5.

Installation

Extract formulix from formulix-drupal-0.1.2.zip to web/modules/custom/formulix, enable the module and rebuild caches. This custom ZIP is not a Composer/Drupal.org release.

Configuration

Under Configuration → Content authoring → Text formats and editors, edit a CKEditor 5 format for trusted users. Add the four Formulix buttons and configure the HTTPS API URL and domain-bound public key.

API and public key

The default URL is the official service, https://api.formulix.com.br. The key is optional: without one, the editor’s domain uses the Free plan; when it runs out, the dialog shows a sign-up link. Register the domain in the dashboard and choose a plan; registration covers its subdomains and the site keeps working without a key.

Preview and insertion content is sent to the API. Use only the domain-bound public key in the browser, never administrator, SMTP or Mercado Pago credentials. See authentication, errors and limits and the privacy policy.

Use

Insert a formula, calculation, graph or chemistry item and double-click to edit again. Uploads use FileRepository and Drupal’s native image provider. Test save/reopen and image attachment to content. The module uses core libraries without bundling another CKEditor.

Known limits

Run locally on Drupal 10.6.0/PHP 8.3: all four types, native uploads, saving and editing again. Drupal 11 is declared but has not been run. Sources are included in assets/source/, outside module discovery.

The Word OMML/RTF clipboard path remains specific to TinyMCE. Word paste on the other platforms and using different languages at the same time are not supported yet.
