MessageSequenceChartPlugin

TODO:

• Submit plugin to latest 5.1 branch (currently exists only in trunk)
• Prevent wysiwyg editor from messing up the code between %MSC% and %ENDMSC% tags.
• Improved error message for the configuration problem: MessageSequenceChart.pl script not found from the path specified in mscScript setting.
• Add support for other image formats (SVG, EPS and server side image maps are supported by mscgen)
• Add support for other fonts (-F option specifies font for rendering PNG output. This is only supported if mscgen was built with USE_FREETYPE and is ignored otherwise)

DONE:

• Improved error message for the mscgen syntax error (mscgen command fails because of typos in input).
• Improved error message for the configuration problem: mscgen executable not found from the path specified in mscGenCmd setting.
• Fix lib/TWiki/Plugins/MessageSequenceChartPlugin/DEPENDENCIES
  • Should not be empty (dependencies to Perl modules and mscgen should be here)
  • See EasyTimelinePlugin as example how to do it properly

WONTFIX:

• Improved error message for the access right problem (when user is not allowed to change the topic, but images would need to be generated and attached to the topic).
  • Now the plugin documentation MessageSequenceChartPlugin.txt does not anymore contain %MSC% calls and this problem should not occur anymore or should occur very rarely.
