A Drupal 8 input filter to convert [Title string] into links.
To create wiki-style inputs for links, so that editors do not need to lookup additional content while writing.
- Create an input filter to support [string] replacement, where "string" is a node title or taxonomy term.
- Create a plugin system to register additional types of entities to be used with the filter.
- Create a means to generate placeholder content if the string fails to match any targets.
