Re: Issue with modulefinder - jython 2.5.3

Thanks Jim for the quick reply.

Do you know of any module or library that can provide me the list of modules used by  a script that I can embed within my java application?

Thanks,
Pradeep V.B.

Subject: Re: [Jython-dev] Issue with modulefinder - jython 2.5.3

Two problems:

1. Standalone has issues for inspecting Lib as a filesystem, see http://bugs.jython.org/issue2143

2. But more importantly, modulefinder itself depends on Python bytecode (see https://github.com/jythontools/jython/blob/master/lib-python/2.7/modulefinder.py#L19), which is not compatible with Jython.

This is why modulefinder is excluded in 2.7 (https://github.com/jythontools/jython/blob/master/CPythonLib.includes). Sorry it's in 2.5.

I suppose it would be possible to port modulefinder to Jython, but I don't know scope. It could be a useful PyPI project as well.

Hi,

I am trying to use modulefinder module to get the used modules in a python script. But I get the below exception.

I am using Jython-standalone-2.5.3 engine to execute this script which prints the modules used by scriptfile.py. I tried using jython-standalone-2.7-b3.jar and I get no module found error for “modulefinder”.

Can someone help me in finding the issues with modulefinder.
