I'm building a custom language plugin and I've run in kind of a brick wall of Parameter hints (ctrl + p) and apart from that it has to be done via ParameterInfoHandler I don't know what next as that part is blank in tutorial page.
Is there any other material that might give a simple example of how to use it? The only method that is triggered in debugger is findElementForParameterInfo and I've found a ParameterInfoUtils:
PsiReferenceParameterList referenceParameterList = ParameterInfoUtils.findParentOfType(
context.getFile(), context.getOffset(), PsiReferenceParameterList.class
Which unfortunately always returns null... can anybody please point me into the right direction of which methods are important, what they should return (an Object is a little bit imprecise) or how to use that utils? At least a simple example that would serve a static paramater for any method would be nice.
I'd really appreciate it and wish you a nice day, David.
