In my Windows build of emacs, when I put the cursor in a latex equation and
run
M-x org-toggle-latex-fragment
then things chug along for a second but then fail. In the *Org Preview
LaTex Output* buffer, I see the message:
This is dvipng 1.15 Copyright 2002-2015 Jan-Ake Larsson
[1
dvipng: Fatal error, cannot open output file
c:/Users/scott/AppData/Local/Temp/"orgtex4628hQG.png
The reason for the failure is the leftover quote (...Temp/"orgtex...) in
the expected png output file. With some hackery, I can see that the
command that's being run is:
dvipng -fg "rgb 0 0 0" -bg "rgb 1 1 1" -D "102.0" -T tight -o
"c:/Users/scott/AppData/Local/Temp/""orgtex4628hQG".png
"c:/Users/scott/AppData/Local/Temp/orgtex4628hQG.dvi"
If I paste that into a cygwin xterm, it runs fine on the .dvi file that's
still in the Temp directory. But the command fails in a Windows cmd
window; if I remove the extra quotes, then the command works in the cmd
window too.
The extra quote comes from the default customization for the dvipng
image-converter field of org-preview-latex-process-alist:
dvipng -fg %F -bg %B -D %D -T tight -o %o%b.png %f
where the %o%b part of the customization concatenates two strings that are
already quoted. That's OK for *nix but apparently not for Windows.
I don't see a way to change the customization to fix this; can anyone take
a look at the elisp?
Thanks,
Scott

This command should read :
dvipng -fg %F -bg %B -D %D -T tight -o "%o%b.png" %f
and the args shouldn't be quoted before.
Unquoting those strings will possibly require to change other command
strings.

Thanks Fabrice. After more experimentation, I found that image-converter
field of the customization alist should be:
("dvipng -fg %F -bg %B -D %D -T tight -o \"%o%b\.png\" %f")
If this also works for *nix, then I hope that the org-mode maintainers will
make this string the new default. If it doesn't work on linux, then I hope
that it's possible to come up with a string that works in both OS families
(and that could be the new default). I'll be back on Linux in a few
months, and would love to keep a simple, cross-platform .emacs file.

I introduced %O, which is the absolute output file name, as
a replacement for %o%b.extension.
Could you confirm the bug is fixed?

Happy to try it out. Should I expect the change on elpa/org sometime soon?
