A python module for unpacking and inspecting Java Class files, JARs, and collections of either.
It can do deep checking of classes to perform comparisons of functionality, and output reports in multiple formats.
If you have suggestions, please use the issue tracker on github. Or heck, just fork it!
- Python 2.6 or later (no support for Python 3)
- Setuptools
- Cheetah is used in the generation of HTML reports
In addition, the following tools are used in building and testing the project.
All of these packages are available in most linux distributions (eg. Fedora), and for OSX via MacPorts.
This module uses setuptools, so running the following will build the project:
python setup.py build
to install, run:
sudo python setup.py install
Tests are written as unittest test cases. If you'd like to run the tests,
simply invoke:
python setup.py test
There is also a custom pylint command, which can be use via:
python setup.py pylint
If you'd prefer to build an RPM, see the wiki entry for Building as an RPM.
-
classinfo - similar to the javap utility included with most JVMs. Also does provides/requires tracking.
-
classdiff - attempts to find differences between two Java class files
-
jarinfo - prints information about a JAR. Also does provides/requires tracking.
-
jardiff - prints the deltas between the contents of a JAR, and runs classdiff on differing Java class files contained in the JARs
-
manifest - creates manifests, signs JAR with OpenSSL
-
distinfo - prints information about a mixed multi-jar/class distribution, such as provides/requires lists.
-
distdiff - attempts to find differences between two distributions, deep-checking any JARs or Java class files found in either directory.
