Re: [HTCondor-users] HTCondor ClassAd attributes list in python bindings

[Brian Bockelman <bbockelm@xxxxxxxxxxx>]

Hi Alessandro,

Looking at the code for condor_submit, it appears to simply copy the tool's environment variables into the Env string.  You can do the same with os.environ and some string manipulation.

Oddly enough, we don't provide a function to convert a python list to an environment string.  I'll add that to my list.  It would be nice if you could do something like:

ad["Env"] = classad.dictToEnv(os.environ)

Now i would need to source a file with some others environment variables definition (actually an OpenFOAM environment definition). is it possible to source a bash file from condor configuration file?
