 ALTERNATE_EDITOR breaks quoted paths on Windows
Date: Thu, 3 Oct 2019 17:40:28 +0000

The patch for bug #25082 appears to have broken quoted paths being passed to emacsclientw on Windows.

w32_execvp doesn’t handle this because it doesn’t quote the path argument to execvp (ultimately to CreateProcess?).

So the patch prevents any possibility of passing a path with spaces as the alternate editor on Windows.

It would have been nice (perhaps) if this had been made a new different command line switch.

Could you please show a (non-)working example where this problem can
be seen?

Thanks.

The following command used to work before the path was applied:

[C:\] "c:\Program Files\emacs\bin\emacsclient.exe"  -a "c:\Program Files\emacs\bin\runemacs.exe" n:\wilsonp\emacs.el
c:\Program Files\emacs\bin\emacsclient.exe: error executing alternate editor "c:\Program Files\emacs\bin\runemacs.exe"

Thanks, I will look into this when I have time, if no one beats me to
it.
