Generate UML from Perl code?

[marvi]

Is there a tool that generates UML diagrams from Perl source code?

Super Search here yields two root nodes asking this ('UML' in both title and text):

1. UML for PERL?
2. Perl UML conventions

A perl interface to Dia looks especially promising

Simon Johnston <[e-mail]> has written a Perl AddIn for Rose. He talked about it at TPC4. You can find it at: http://www.rationalrose.com/addins/RosePerl-1_0_1.htm

The code I posted at Graph your Perl inheritance structure will draw an inheritance diagram from an existing Perl program. You should be able to modify it to make UML diagrams pretty easily. But you won't be able to edit them graphically.

But you don't say what UML diagrams you're interested in (there are lots of different kinds). Some possibilities that I can think of for diagramming:

• use the debugger hooks to build a sequence or collaboration diagram
• analyze the @ISA structure for a class diagram like my example does
• analyze your POE structures for a class diagram
• analyze the 'use' and 'require' structures (you can use the debugger hooks here too) for a component diagram

Another good option is AutoDia which will produce XML suitable for the Dia drawing program. Typically you'll need to so some editing of the diagram after generation, but it seems to get the inheritance down okay. I like it as a starting point rather than building the whole class hierarchy by hand.
