Anchor feature for CKEditor 5, adapted for Drupal

@northernco/ckeditor5-anchor-drupal

This package implements the anchor feature for CKEditor 5. It allows inserting anchor elements (ID field) into the edited content and offers the UI to create and edit them.

This is a Drupal-adapted fork of the original plugin by bvedad.

Developing the package

To read about the CKEditor 5 framework, visit the CKEditor5 documentation.

Available scripts

Npm scripts are a convenient way to provide commands in a project. They are defined in the package.json file and shared with other people contributing to the project. It ensures that developers use the same command with the same options (flags).

All the scripts can be executed by running npm run <script>. Pre and post commands with matching names will be run for those as well.

The following scripts are available in the package.

start

Starts a HTTP server with the live-reload mechanism that allows previewing and testing plugins available in the package.

When the server has been started, the default browser will open the developer sample. This can be disabled by passing the --no-open option to that command.

You can also define the language that will translate the created editor by specifying the --language [LANG] option. It defaults to 'en'.

Examples:

# Starts the server and open the browser.
npm run start

# Disable auto-opening the browser.
npm run start -- --no-open

# Create the editor with the interface in German.
npm run start -- --language=de

test

Allows executing unit tests for the package, specified in the tests/ directory. The command accepts the following modifiers:

• --coverage – to create the code coverage report,
• --watch – to observe the source files (the command does not end after executing tests),
• --source-map – to generate source maps of sources,
• --verbose – to print additional webpack logs.

Examples:

# Execute tests.
npm run test

# Generate code coverage report after each change in the sources.
npm run test -- --coverage --test

lint

Runs ESLint, which analyzes the code (all *.js files) to quickly find problems.

Examples:

# Execute eslint.
npm run lint

stylelint

Similar to the lint task, stylelint analyzes the CSS code (*.css files in the theme/ directory) in the package.

Examples:

# Execute stylelint.
npm run stylelint

dll:build

Creates a DLL-compatible package build which can be loaded into an editor using DLL builds.

Examples:

# Build the DLL file that is ready to publish.
npm run dll:build

# Build the DLL file and listen to changes in its sources.
npm run dll:build -- --watch

dll:serve

Creates a simple HTTP server (without the live-reload mechanism) that allows verifying whether the DLL build of the package is compatible with the CKEditor 5 DLL builds.

Examples:

# Starts the HTTP server and opens the browser.
npm run dll:serve

translations:collect

Collects translation messages (arguments of the t() function) and context files, then validates whether the provided values do not interfere with the values specified in the @ckeditor/ckeditor5-core package.

The task may end with an error if one of the following conditions is met:

• Found the Unused context error – entries specified in the lang/contexts.json file are not used in source files. They should be removed.
• Found the Context is duplicated for the id error – some of the entries are duplicated. Consider removing them from the lang/contexts.json file, or rewrite them.
• Found the Context for the message id is missing error – entries specified in source files are not described in the lang/contexts.json file. They should be added.

Examples:

npm run translations:collect

translations:download

Download translations from the Transifex server. Depending on users' activity in the project, it creates translations files used for building the editor.

The task requires passing the URL to Transifex API. Usually, it matches the following format: https://www.transifex.com/api/2/project/[PROJECT_SLUG].

To avoid passing the --transifex option every time when calls the command, you can store it in package.json, next to the ckeditor5-package-tools translations:download command.

Examples:

npm run translations:download -- --transifex [API URL]

translations:upload

Uploads translation messages onto the Transifex server. It allows for the creation of translations into other languages by users using the Transifex platform.

The task requires passing the URL to the Transifex API. Usually, it matches the following format: https://www.transifex.com/api/2/project/[PROJECT_SLUG].

To avoid passing the --transifex option every time when you call the command, you can store it in package.json, next to the ckeditor5-package-tools translations:upload command.

Examples:

npm run translations:upload -- --transifex [API URL]
