bug#54730: AW: bug#54730: 28.1; vhdl-update-sensitivity-list not working in Windows

[Cyril Arnould]

Addendum: I’ve specified «on Windows» because Emacs is associated more with GNU/Linux

operating systems and I didn’t want any confusion. I don’t have any GNU/Linux OS installed,

but I could try in a VM if that helps.

I’ve added an example file you can visit in the attachment. To reproduce, simply

put the cursor inside the process (M-g-g 30 RET) and execute

vhdl-update-sensitivity-list-process (C-c C-u C-s). I’m getting the following backtrace:

 

Debugger entered--Lisp error: (void-variable proc-end)

  (vhdl-re-search-forward "[<:]=" proc-end t)

  eval((vhdl-re-search-forward "[<:]=" proc-end t))

  vhdl-update-sensitivity-list()

  vhdl-update-sensitivity-list-process()

  funcall-interactively(vhdl-update-sensitivity-list-process)

  command-execute(vhdl-update-sensitivity-list-process)

 

Thanks!

You say "on Windows" because it works on other systems?

Can you please provide a complete recipe, including any file(s) one
has to visit etc.?  I don't use VHDL, so I need very precise
instructions to reproduce and debug the problem.  I'm a bit surprised
that you get that void-variable error, since I see proc-end being
let-bound in vhdl-update-sensitivity-list.  I'm probably missing
something.  Could you perhaps set debug-on-error non-nil, and post the
Lisp backtrace from the error?

Thanks.
