Problem with Equation Editor plugin on Windows

[Johan Andberger]

Hi

I have a problem with the Equation Editor plugin for Zim 0.65 on Windows 10. The equation.dvi file in AppData/Local/Temp/zim-... gets generated fine, but dvipng fails with

dvipng "-q" "-bg" "Transparent" "-T" "tight" "-o" "c:\users\firstn~1\appdata\local\temp\zim-FirstName%20LastName\equation.png" "c:\users\firstn~1\appdata\local\temp\zim-FirstName%20LastName\equation.dvi" fehlgeschlagen. Fehlercode: 2

Opening a terminal and executing the command manually gives

C:\Users\FirstName LastName>dvipng "-q" "-bg" "Transparent" "-T" "tight" "-o" "c:\users\firstn~1\appdata\local\temp\zim-FirstName%20LastName\equation.png" "c:\users\firstn~1\appdata\local\temp\zim-FirstName%20LastName\equation.dvi"
This is dvipng 1.15 Copyright 2002-2015 Jan-Ake Larsson

dvipng: Fatal error, unacceptible format spec in output file name

Changing the command to e.g.

C:\Users\FirstName LastName>dvipng "-q" "-bg" "Transparent" "-T" "tight" "-o" "c:\users\firstn~1\appdata\local\temp\equation.png" "c:\users\firstn~1\appdata\local\temp\zim-FirstName%20LastName\equation.dvi"
This is dvipng 1.15 Copyright 2002-2015 Jan-Ake Larsson

i.e. just removing zim-FirstName%20LastName from the output path, executes fine. It seems to me that dvipng can't parse output paths with % in them very well, which stems from the fact that I have a username with a space in it.

This is an issue with dvipng, so I'm not sure if I should post this here. It could however be solved by removing %20 from the folder name, is this possible?

Kind regards
Johan

Asked on the mailing list for dvipng, http://lists.nongnu.org/archive/html/dvipng/2016-07/msg00001.html

I made the following change to zim/fs.py to fix the problem: "dir = Dir((root, 'zim-%s' % user))" to "dir = Dir((root, 'zim'))".

Haven't had any bad things happen so far.

probably best if we keep same tmp dir but change pwd and call dvipng with relative pathname
