"contrib/workflow/showworkflow" is KDE centric

[trac@…]

I reckon this should call evince where kpdf is not available (like on Gnome desktops, which is a pretty common occurance). Here's a patch:

How about supporting open (OSX) and start (Windows) as well?

How about supporting open (OSX) and start (Windows) as well?

The graphviz tools are not distributed as part of those operating systems. Is it necessary to support them?

[Christian Boos]

I'll add windows support at least.

windows version of showworkflow script

[jhn@…]

showworkflow.cmd​

i ported the shell script to run on windows. it's pretty much a direct translation. one of the differences is that it does not generate a PS and a PDF, just a PNG. i wrote this about a year ago so i don't remember if it was because the required tools weren't included in the windows graphviz install, or whether i just had no need for the PDF version.

[jhn@…]

the reason i didn't include the PS and PDF parts of the script was that ps2pdf requires the additional install of ghostscript and i only wanted PNGs anyway. it would be easy to add them to the script if someone wanted to. PNGs are better though =)

The current trunk version is looking​ for evince as well:

Can someone apply or review the cmd file for windows?

[psuter <petsuter@…>]

The cmd file works fine here, after installing ​Graphviz 2.28.0 and making sure dot is in %PATH% (set PATH=%PATH%;"C:\Program Files (x86)\Graphviz 2.28\bin"). I also had to change

-workflow_parser.py %options% "%config%" > "%dot%"
+python workflow_parser.py %options% "%config%" > "%dot%"

because the Python interpreter registered for executing .py files does not know about Trac.

Adding PS an PDF export seems to work as well, without additional dependencies like ghostscript.
