Jeff integrated JDepend last nigth. It is under a BSD license and has a simple parser. I am going to use the JavaCC parser to do some other neat things as well. I am also interested (most interested) in generating visualizations of the metrics. > I committed a description of metrics in xdocs that would be nice to see. > I also started to see how we could do that with the visitors but not sure > yet about a couple of things. What I was planning with one of the visitors was to populate an small model that represents a Java source file. Then once you have populated a set of these classes that represent a source file (or classfile) then perform the metrics on those. There are also many other possible uses for a object model for a source file too. > If we have to create something like code audit there is some need to enhance > the parser to have waaaaaaay more concrete nodes and also add a couple of > helper methods to these nodes. The parser is simply there as a start, the only thing I've added is the ability to reuse the parser. Same thing I did with the Velocity parser. The parser will also require some work to trap whitespace properly, say if we wanted to make a pretty printer. > my parser skills are a bit rusty but if someone want to give it a shot I can > provide the javadoc related to the ast nodes in webgain audit.

I think that would be fine as regenerating the parser from the grammar shouldn't affect the nodes and I don't think we'll be changing the names of the productions in the grammar so that should be fine. > As I see it there is probably a need for 2 parsers.

Take a look at JDepend we could definitely use that for metrics. The java parser we have I intend to be a rigorous parser and I'm going to add 1.4 support (i believe someone just did on the javacc list) and support for aspectj. I would really like to start coming up with some metrics for aspect oriented code. I'm going to the AOSD conference in April so hopefully I'll get some cool ideas there. > Stephane > > > -----Original Message----- > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > > Sent: Monday, February 25, 2002 6:52 AM > > To: [EMAIL PROTECTED] > > Subject: cvs commit: jakarta-turbine-maven/src/templates/build > > build-metrics.xml Control.vm build.xml > > > > > > brekke 02/02/24 21:51:50 > > > > Modified: . build-bootstrap.xml > > src/templates/build Control.vm build.xml > > Added: src/templates/build build-metrics.xml > > Log: > > Preliminary support for generating some source code metrics via > > <a > > href="http://www.clarkware.com/software/JDepend.html";>JDepend</a>. > > Currently you need to have the JDepend jar in your > > $ANT_HOME/lib directory. > > > > Added a build-metrics.xml template to be generated when the > > build system is > > gen'd.
