## NAME

IkiWiki::Plugin::mscgen - embed message sequence chart

## SYNOPSIS

In the ikiwiki setup file, enable this plugin by adding it to the list of active plugins.

    add_plugins:
      - mscgen

## DESCRIPTION

This plugin provides the msc [[ikiwiki/directive]].
This directive allows embedding [mscgen](http://www.mcternan.me.uk/mscgen/)
message sequence chart graphs in an ikiwiki page.

Here's an example that shows how an mscgen message sequence chart is embedded into an ikiwiki page.

    \[[!msc src="""
      arcgradient = 8;

      a [label="Client"],b [label="Server"];

      a=>b [label="data1"];
      a-xb [label="data2"];
      a=>b [label="data3"];
      a<=b [label="ack1, nack2"];
      a=>b [label="data2", arcskip="1"];
      |||;
      a<=b [label="ack3"];
      |||;
    """]]

Security implications: to be determined.

This plugin borrows heavily from the [[graphviz|plugins/graphviz]] plugin written by [[JoshTriplett]].
