Subject: 26.0.50; Compiled ps-print.el is non-functional
Date: Sat, 22 Apr 2017 05:41:22 +0200

Hello,

ps-print.el has become non-functional for me in compiled form since some
time (days?  weeks? ... not much longer).  It produces only empty .ps
documents.

Here is a very simple recipe for emacs -Q (from *scratch*):

M-: (require 'ps-print) RET

M-: (ps-spool-buffer-with-faces) RET

Switch to the buffer *Post Script*.  The created document ends with


| BeginDoc
| %%EndSetup
| 
| %%Trailer
| %%Pages: 0
| 
| EndDoc
| 
| %%EOF

If I save the buffer to a .ps file and open it with a viewer, I get a
blank page.

Now I repeat the recipe with the source file ps-print.el loaded.  I get
the expected result this time.  Hmm.


Thanks in advance,

Michael.

Does the problem go away if you byte-compile ps-print.el with Emacs
25?

A certain bytecode bug which might have caused this was fixed just
recently. Could you try `make bootstrap` and see whether the issue still
persists?

My bad, this was another bug (argh) in bytecomp.el to do with singleton
clauses in cond. I've pushed a fix to master for this, and
(ps-spool-buffer-with-faces)
seems to work as intended, with the output postscript attached. Could
you verify this?

Thanks,
Vibhav

Seems to work here, thanks.

Yes, it works again for me as well.

Thanks for your efforts!
