In my opinion, Unified Modeling Language (UML) is useful only for really large projects where object relationships must be clearly defined from the very beginning. In (my) reality, object relationships change. (This is quite contrary to the opinion of my computer science department, where they require UML diagrams for even the simplest projects. I'm talking Java programs that draw a square to the screen.)

I personally don't do any projects that justify the use of UML--in any language. Nonetheless, I found ArgoUML, which appears to be an open source UML development tool written in Java. You might be able to extend it to generate Perl code skeletons (it claims to be "modular and extensible").

Hope this helps.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
