[cl-ppcre-devel] debugging of RE matching

[Philipp Marek]

Hello Edi,
hello Hans,


thank you very much for your feedback.
I've done nearly all of the requested changes, and wrote some
documentation, too.

The points that are still open are
 * I can't get the (with-trace-output) macro working (see last commit on
   my branch) - does (eval-when) stop working as expected when it's
   not in a top-level form?
 * In practical use I've seen a few errors - wrong indizes, and
   some other error. Will try to fix, but help is appreciated, of course.

Is this question about the

  (let ((scanner (create-scanner-aux match-fn

line? If it is, then I put the (lambda) below to get a minimal diff.

If the question is "why is that not in (create-matcher-aux)" - because
*debug-results* and *ppcre-debug-depth* have to be bound _outside_ the
create-matcher-aux calls, and not re-bound within.

Or am I misunderstanding your question, still? Then please clarify.


Thank you very much!

Regards,

Phil
