Just using this item so that I can check in changes in Subversion. For more information please visit MessageSequenceChartPluginDev and MessageSequenceChartPlugin.


  • 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)


  • 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


  • 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.
