   Anyone want to weigh in on this one? I'd love an easy way to generate a source file mapping for non-obfuscated code on my primary source directory.

   @richarddbarnett did you ever solve this? do you have a script that does it?

   thanks!

   Sorry, I made no progress on this. Mapping each stack frame to a path within a repo (or a special "third-party" marker) could be done in the Squash client or server; on the server this doesn't scale so well for heterogenous clients (since the server needs to be configured with repo info for each client) but is more efficient from the point of view of the client (& the change itself requires Ruby skills I don't have).

   I'm not a Ruby expert, but if I get a second I might dive in. I'm trying to integrate squash into a Play! application, which means that there is a very simple and direct mapping from source locations to class names starting at one top level source directory, but there is also bytecode insertion and a few other weird things happening. Not sure how squash will react to this.

   When I attempted to generate a mapping file with yguard, I got an empty XML file. Not sure what I'm doing wrong there, and the docs on how to do this are extremely limited. I might play around with it some more this weekend.

   But without stack traces, squash is pretty limited in its usefulness.

   Here's the Ant build.xml I used to generate the mapping file with yguard:

   <?xml version='1.0' encoding='UTF-8'?>
   <project name='project' default='yguard' basedir='.'>
     <target name='init'>
       <property name='jar' value='target/xyzzy.jar'/>
       <property name='obfjar' value='target/xyzzy.obf.jar'/>
       <property name='renamelog' value='renamelog.xml'/>
     </target>
     <target name='yguard' depends='init'>
       <taskdef name='yguard' classname='com.yworks.yguard.YGuardTask'
                classpath='/Users/richard/Downloads/yguard-2.4/lib/yguard.jar'/>
       <yguard>
         <inoutpair in='${jar}' out='${obfjar}'/>
         <externalclasses>
           <fileset dir='target/lib'>
             <include name='*.jar'/>
           </fileset>
         </externalclasses>
         <rename mainclass='com.xyzzy.XyzzyMain' logfile='${renamelog}'>
           <property name='error-checking' value='pedantic'/>
           <keep>
             <class classes='private' methods='private' fields='private'>
               <patternset>
                 <include name='**'/>
               </patternset>
             </class>
           </keep>
         </rename>
       </yguard>
     </target>
     <target name='clean' depends='init'>
       <delete file='${obfjar}'/>
     </target>
   </project>
