How to use CPD on ITK Code?
- Currently, CPD only support the following extensions for c++ files ".h", ".c", ".cpp", ".cxx", ".cc", ".C".
Short term solution
- So you first need to copy all the ITK sources and change the extension of all *.txx files to .cc
- Then first replace existing /path/to/pmd/bin/cpd.sh by the following:
#!/bin/sh
## This will work in the majority of shells out there...
## This will parse a directory named on the command line and produce a
## cut and paste report for c++ files in that directory (or 'c', if you
## set the environment variable LANGUAGE to 'c').
## Note that other rules are only for Java code not C source.
## If you run into java.lang.OutOfMemoryError, try setting the environment
## variable HEAPSIZE to e.g. 1024m

java $HEAPSIZE -cp $classpath net.sourceforge.pmd.cpd.CPD --minimum-tokens $MINIMUM_TOKENS --files $DIRECTORY --language $LANGUAGE --format net.sourceforge.pmd.cpd.XMLRenderer
- Then run
$ cd /path/to/pmd/bin $ ./cpd.sh /path/to/Insight/Code 500
Long term solution
- Modify CPPLanguage.java in order to make CPD work with txx file.
- Debug see http://sourceforge.net/projects/pmd/forums/forum/188192/topic/3778230
