Configuration Reference¶

Yaml Configuration Reference¶

When configurating the CKEditor using Yaml, these are the property names that are currently used:

processing
editor

processing¶

Configuring transformations kicks in the RteHtmlParser API of TYPO3, to only allow certain HTML tags and attributes when saving the database or leaving the database to the RTE. However, defining transformations towards RTE is not really necessary anymore. Defining more strict processing options when storing content in the database also needs to be ensured that CKEditor allows this functionality too.

This configuration option was previously built within RTE.proc and can still be overridden via Page TSconfig. Everything defined via “processing” is available in RTE.proc and triggers RteHtmlParser options.

editor¶

Editor contains all RTE-specific options. All CKEditor-specific options, which one could imagine are available under “config” property and handed over to CKEditor’s instance-specific config array.

All other subproperties are usually handled via TYPO3 and then injected in the CKEditor instance at runtime. This is useful for registering extra plugins, like the TYPO3 core does with a custom Typolink.js plugin, or adding third-party plugins like handling images.

editor.config¶

editor.config:

Configuration options For a list of all options see https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html

editor.config.language

defines the editor’s UI language, and is dynamically calculated (if not set otherwise) by the backend users’ preference.

editor.config.contentsLanguage

defines the language of the data, which is fetched from the sys_language information, but can be overridden by this option as well. For referencing files, TYPO3’s internal “EXT:” syntax can be used, for using language labels, TYPO3’s “LLL:” language functionality can be used.

editor.config.contentsCss

defines the CSS file of the editor and the styles that can be applied.

Example:

editor.config.contentCss: "EXT:rte_ckeditor/Resources/Public/Css/contents.css"

This is the default, as defined in EXT:rte_ckeditor/Configuration/RTE/Editor/Base.yml.

editor.config.style

Sets the style

editor.config.toolbarGroup

This defines, which toolbarGroups (and corresponding buttons) will be visible in the toolbar.

Example:

toolbarGroups:
  - { name: clipboard, groups: [ clipboard, cleanup, undo ] }

See Configuration Using the toolbarGroups Method for more information.

editor.config.removeButtons

deactivates default buttons rendered in the toolbar.

Example:

removeButtons:
- Anchor
- Superscript
- Subscript
- Underline
- Strike

See removeButtons for more information.

editor.*¶

editor.externalPlugins: is a list of plugins with their routes and additional configuration options, the main “resource” subproperty needs to be set which is a JavaScript file using CKEditor’s plugin API, see rte_ckeditor/Configuration/RTE/Editor/Plugins.yml.
