bug#11864: 24.1.50; error instrumenting pcase in completion-at-point for edebug

[Michael Heerdegen]

Hello,

pcase.el comes with declarations for edebug.  However, if I try to
instrument the defun of `completion-at-point' in minibuffer.el (in
emacs -Q), I get the following error:

edebug-syntax-error: Invalid read syntax: "Expected lambda expression"

I guess this should work - but please correct me if I'm wrong.


Thanks,

Michael.

You need to explicitly load pcase first.
I guess this is basically the same issue as http://debbugs.gnu.org/10577 .

Indeed.

(Is it possible to autoload the edebug declarations?  Just a thought.)


Thanks,

Michael.

Autoloading the edebug declarations themselves would require new
autoload machinery, but it should not be difficult to change edebug so
that it autoloads the macro before instrumenting the code.

I'm unable to reproduce this in Emacs 27, so I'm going to go ahead and
guess that it's been fixed in the eight years since it was reported, and
I'm closing this bug report.  If you're still seeing this, please reopen.
