This responder returns a json containing all imported classes in a fitnesse context and their public methods and parameter types. Also returns scenario's on page if these are present. Scenario's are de-camelcased and parameters are also provided.
This json is usable as a basis for context-aware autocompletion in the wiki editor.
The easiest way: use toolchain-fitnesse-plugin. This incorporates bootstra-plus and autocmplete-responder and does all the configuration automagically.
Otherwise:
When the jar is in your FitNesse plugins directory, add Responders=autoComplete:nl.praegus.fitnesse.responders.AutoCompleteResponder to your plugins.properties file.
For more details on usage and an implementation: see the readme in Bootstrap-plus-theme repository
