⚠️ CKEditor 4: End of Life and Extended Support Model until Dec 2026

CKEditor 4 was launched in 2012 and reached its End of Life (EOL) on June 30, 2023.

A special edition, CKEditor 4 LTS ("Long Term Support"), is available under commercial terms ("Extended Support Model") for anyone looking to extend the coverage of security updates and critical bug fixes.

With CKEditor 4 LTS, security updates and critical bug fixes are guaranteed until December 2026.

About this repository

This builder is a tool that creates CKEditor release files for the main "preset" configurations officially distributed at https://ckeditor.com/. It is targeted to the CKEditor core team, to test the preset builds, to update the ckeditor.com website on new releases and to generate the nightly builds.

A preset is a CKEditor configuration for building that includes a specific set of plugins. Currently, there are 3 presets defined: standard, basic and full.

The original source code from the official CKEditor repositories is used for the build.

Cloning this Code

To clone this code:

> git clone https://github.com/ckeditor/ckeditor4-presets.git

Then, the registered submodules need to be updated:

> git submodule update --init

Running the Builder

The build.sh is the only file you should care about. It downloads CKBuilder, if necessary, and execute the building process.

This is the command syntax:

> build.sh standard|basic|full [all]

The optional "all" argument tells the builder to include all plugins available in the ckeditor4 repository, even if they're not included in the preset.

The build will be then created in the build/[preset name] folder.

Examples:

> # Build a "standard" release.
> build.sh standard

> # Build a "basic" release, including all plugins available.
> build.sh basic all

Creating custom Presets

Apart from using predefined presets, you can create a custom preset manually and use it with the build.sh script. As an example, let's create a preset including basic configuration with the Editor Placeholder plugin.

1. Adding the build configuration file

Create a builder configuration file at presets/custom-build-config.js:

var CKBUILDER_CONFIG = {
    skin: 'moono-lisa',
    ignore: [
        'bender.js',
        'bender.ci.js',
        '.bender',
        'bender-err.log',
        'bender-out.log',
        '.travis.yml',
        'dev',
        '.DS_Store',
        '.editorconfig',
        '.github',
        '.gitignore',
        '.gitattributes',
        'gruntfile.js',
        '.idea',
        '.jscsrc',
        '.jshintignore',
        '.jshintrc',
        'less',
        '.mailmap',
        'node_modules',
        '.npm',
        '.nvmrc',
        'package.json',
        'package-lock.json',
        'README.md',
        'tests'
    ],
    plugins: {
        about: 1,
        basicstyles: 1,
        clipboard: 1,
        floatingspace: 1,
        list: 1,
        indentlist: 1,
        enterkey: 1,
        entities: 1,
        link: 1,
        editorplaceholder: 1,
        toolbar: 1,
        undo: 1,
        wysiwygarea: 1
    }
};

2. Adding the editor configuration file

Create an editor configuration file at presets/custom-ckeditor-config.js:

CKEDITOR.editorConfig = function( config ) {
    // The toolbar groups arrangement, optimized for a single toolbar row.
    config.toolbarGroups = [
        { name: 'document', groups: [ 'mode', 'document', 'doctools' ] },
        { name: 'clipboard', groups: [ 'clipboard', 'undo' ] },
        { name: 'editing', groups: [ 'find', 'selection', 'spellchecker' ] },
        { name: 'forms' },
        { name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ] },
        { name: 'paragraph', groups: [ 'list', 'indent', 'blocks', 'align', 'bidi' ] },
        { name: 'links' },
        { name: 'insert' },
        { name: 'styles' },
        { name: 'colors' },
        { name: 'tools' },
        { name: 'others' },
        { name: 'about' }
    ];

    // The default plugins included in the basic setup define some toolbar buttons that
    // are not needed in a basic editor. These are removed here.
    config.removeButtons = 'Cut,Copy,Paste,Undo,Redo,Anchor,Underline,Strike,Subscript,Superscript';

    // Dialog windows are also simplified.
    config.removeDialogTabs = 'link:advanced';

    // Finally, configure editor placeholder text.
    config.editorplaceholder = 'Type something here...';
};

3. Building a custom preset

Run build.sh file:

> # Build a custom "custom" preset.
> build.sh custom
