Dokuwiki has an “autolinking” feature:
What is auto-linking
DokuWiki already automatically links camel-cased words. It will find a page with the same name, and turn your text into a link. The Autolink plugins take that a step further, allowing you to add links to specific pieces of text. For example, you could make it so that the word “Things” will link to mywiki:things, no matter where it’s found on your wiki.
