Paessler.AnchorLink

Extends the Neos CKE5 link-editor with server-side resolvable anchor links.

Installation

1. Install the package: composer require paessler/anchorlink

2. Enable additional linking options with such config:

"Neos.NodeTypes.BaseMixins:TextMixin": # Or other nodetype
  properties:
    text:
      ui:
        inline:
          editorOptions:
            linking:
              anchorLink: true

3. For all content nodetypes that you would like to be able to link to, inherit from Paessler.AnchorLink:AnchorMixin, e.g.:

Neos.Neos:Content: # Or other nodetype
  superTypes:
    Paessler.AnchorLink:AnchorMixin: true

4. Adjust the rendering for those nodes to insert anchors before them, e.g. there is included a Fusion processor to help with that:

prototype(Neos.Neos:Content).@process.anchor = Paessler.AnchorLink:AnchorLinkAugmenter

Note: this will add an id attribute to the corresponding output. For this to work reliably the corresponding prototype should render a single root element. Otherwise an additional wrapping div element will be rendered. Also the rendered content must not already contain an id attribute because it would be merged with the one from the augmentor in that case.

Configuration

It's possible to configure the content node nodetype that is used for linking. Also it's possible to use a different property for the anchor value and the label via Settings.yaml.

These are the defaults:

Paessler:
  AnchorLink:
    # Only nodes of this type will appear in the "Choose link anchor" selector
    contentNodeType: "Paessler.AnchorLink:AnchorMixin"
    # Eel Expression that returns the anchor (without leading "#") for a given node
    anchor: ${node.properties.anchor || node.name}
    # Eel Expression that returns the label to be rendered in the anchor selector in the Backend
    label: ${node.label}
    # Eel Expression that returns a group for the anchor selector (empty string == no grouping)
    group: ${I18n.translate(node.nodeType.label)}
    # Eel Expression that returns an icon for the anchor selector (empty string = no icon)
    icon: ${node.nodeType.fullConfiguration.ui.icon}

It's possible to disable the searchbox or adjust its threshold via Settings.yaml, the default settings are:

Neos:
  Neos:
    Ui:
      frontendConfiguration:
        "Paessler.AnchorLink":
          displaySearchBox: true
          threshold: 0

Low-level Customization

Finally, it is possible to create a completely custom anchor nodes resolver.

Create a class implementing AnchorLinkResolverInterface that would take the current content node, link and a searchTerm and return an array of options for the link anchor selector and configure it in Objects.yaml like this:

'Paessler\AnchorLink\Controller\AnchorLinkController':
  properties:
    resolver:
      object: Your\Custom\AnchorLinkResolver

Development

If you need to adjust anything in this package, just do so and then rebuild the code like this:

cd Resources/Private/JavaScript/AnchorLink
yarn && yarn build

And then commit changed filed including Plugin.js
