Not an issue!

Just an appreciation for the wonderful and essential package you wrote! It saved my day.

These two features are required by the tests for this package, but I cannot find them anywhere.

Hi,

This is very cool and already useful, but I've hit case where the code makes heavy use of a custom font-lock-fontify-region-function (see: https://github.com/doublep/logview/blob/master/logview.el#L3240), and it seems there's nothing in either Emacs or this library to help me debug it via Edebug.

Consider this as a feature request to also allow stepping user-provided font-lock-fontify-region-function code.

Thank you!

After opening a Clojure source file and invoking M-x font-lock-studio, choosing "Step Into and Debug" from the menu with point at a place where the mini-buffer reports "Keyword with function name matcher", I see the following sort of output in the mini-buffer:

funcall: Invalid function: (edebug-enter (quote edebug-anon9) nil (function (lambda nil (edebug-after 0 0 clojure--search-comment-macro))))

Thankfully, manually invoking edebug-defun on the function in question and then / "Step Into" works :)

Emacs version is 26.1.

BTW, thanks for font-lock-studio!

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  font-lock-studio-show-source()
  font-lock-studio-region(1 25772 nil)
  font-lock-studio(nil)
  call-interactively(font-lock-studio record nil)
  command-execute(font-lock-studio record)

It took me some time to realize that this is because I'm using shackle and have configured it to select windows after displaying them. With it disabled, the error doesn't occur which suggests that the root cause of this is font-lock-studio relying on the default Emacs behavior.
