objective-c-cpd-language's Introduction

# Objective-C CPD Language 

This jar can be used in conjunction with PMD/CPD to scan for copy and pasted code within
XCode projects.  To use this language definition, you need to add the jar to your
PMD/CPD classpath and provide a --language directive indicating that you are scanning
Objective-C code.  Here is a command line example:

java -Xmx512m -classpath asm-3.1.jar:jaxen-1.1.1.jar:pmd-4.2.5.jar:ObjCLanguage-0.0.1-SNAPSHOT.jar net.sourceforge.pmd.cpd.CPD --minimum-tokens 100 --files [Path to XCode project classes] --language ObjectiveC --encoding UTF-8 --format net.sourceforge.pmd.cpd.XMLRenderer

objective-c-cpd-language's Issues

I have parse errors when I try parse objective-C code

I print:
java -classpath “/Users/username/iPhoneProjects/projiOS/projiPad.v2/trunk/projiPad/CPD/ObjCLanguage-0.0.2-SNAPSHOT.jar:/Users/username/iPhoneProjects/projiOS/projiPad.v2/trunk/projiPad/CPD/pmd.jar” net.sourceforge.pmd.cpd.CPD –minimum-tokens 100 –files “/Users/username/iPhoneProjects/projiOS/projiPad.v2/trunk/projiPad” –language ObjectiveC –encoding UTF-8 –format net.sourceforge.pmd.cpd.XMLRenderer > “/Users/username/iPhoneProjects/projiOS/projiPad.v2/trunk/cpd-output.xml”

and have:

there are .mm files in my project, how can I check them?

this tool just checks .m files and .h files，but in my project there are many .mm files.

Support for ObjC Literals?

Are you planning to add support for Objective-C Literals?

Option to discard folder from path

I have --files 'path/to/trunk' option. But it contains the iOS Evernote SDK which code is generated and it contains a lot of copy pasted code blocks). For example NoteStore.m has 36072 lines of code and contains more than 200 copy pasted code blocks. I think the best way to fix that is ignore that by adding option to discard special path.

PMD 5.0.0 incompatible with ObjCLanguage-0.0.7-SNAPSHOT.jar

When using PMD 5.0.0, I get the following error message for every file, and hence no output:

java.lang.NoSuchMethodError: net.sourceforge.pmd.cpd.SourceCode.getCodeBuffer()Ljava/lang/StringBuffer;
    at net.sourceforge.pmd.cpd.ObjectivecTokenizer.tokenize(ObjectivecTokenizer.java:27)

    at net.sourceforge.pmd.cpd.CPD.addRecursively(CPD.java:63)
    at net.sourceforge.pmd.cpd.CPD.main(CPD.java:138)

my CPD command line looks like this (added the logging flag temporarily to get above err msg):

java
-DObjC-CPD-LoggingEnabled=YES
-Xmx512m
-classpath "/tools/pmd/lib/asm-3.2.jar:/tools/pmd/lib/jaxen-1.1.1.jar:/tools/pmd/lib/pmd-5.0.0.jar:/tools/pmd/lib/ObjCLanguage-0.0.7-SNAPSHOT.jar"
net.sourceforge.pmd.cpd.CPD
--files "/project/files/"
--minimum-tokens 100
--language ObjectiveC
--encoding UTF-8
--format net.sourceforge.pmd.cpd.XMLRenderer
> "cpd.xml"

Work-around: download and use PMD 4.2.6.
