Chain multiple macros and processors


This macro allows you to chain multiple macros (including WikiProcessors) together, similar to Unix command line pipes. That means it allows you to feed the output from one macro as input to the next.

The following mimicks the MimeInclude macro:

[[MacroChain(Include(, text/html)]]

This uses the CsvMacro to display a csv file from the repository as a table:

[[MacroChain(Include(trunk/foo/bar.csv), CsvMacro)]]

The following uses the XsltMacro and GraphvizPlugin to create a graph of some xml data:

[[MacroChain(Xslt(graph.xslt, doc.xml),]]
