Creates git like diff stat over a whole svn repository. Only one author and a certain set of files are considered. In addition a chart similar to Code Frequency is created.
This is very raw and not polished software. These are the steps that you need to do to run the software
- build the software with
mvn clean package - check out the part of the subversion repository you're interested in
- run the software in the folder of the working copy you just checked out
The following command line options are supported:
- -author -a
- Required. The authors that should be analyzed.
- -file -f
- Required. The file where to save the generated chart. Will always be a PNG.
- -extension -e
- Optional. The file extensions that should be analyzed.
- -width -w
- Optional. The width of the chart in pixels. Defaults to
1200. - -height -h
- Optional. The height of the chart in pixels. Defaults to
600. - -double -d -retina -r
- Optional. Render in double the resolution, useful for retina Macs. Defaults to
false. - -max -m
- Optional. Commits with more than this number of lines changed will be ignored. Defaults to
10000.
For example
java -Djava.awt.headless=true -jar svn-diffstat/target/svn-diffstat-1.0.0-SNAPSHOT.jar -d -a marschall -e java -f /Users/marschall/tmp/diffstat.png
This is a sample chart generated from an actual code base.
Exception in thread "main" java.nio.channels.NonWritableChannelException

Just try again, somebody committed during the analysis.
I ran it on a subversion repository with about 240k revisions and it takes about 20 minutes.

This project wouldn't have been possible without the work of others:
- SVNKit, a Java Subversion implementation, used to extract all the information from Subversion, TMate open source license
- JFreeChart, a Java chart library, used to build the code frequency char, GNU Lesser General Public License (LGPL)
- Joda-Time, a Java date and time library, use for date calculations, Apache 2.0 License
- JCommander, a Java library to parse command line parameters, Apache 2.0 License
Last but not least I'd like to thank Netcetera for sponsoring the work on this. This was literally a one-weekend-hack as you can see from the commit logs.
