Re: [HTCondor-users] interpolation using the python bindings

[Jose Caballero <jcaballero.hep@xxxxxxxxx>]

Hi again

this is really confusing to me.
So, I have a classad like this in the dictionary

      "+foo" : ' "$(Cluster)" '

After submission, if I run  submit.expand('+foo'), indeed, I get
12345, as expected.
However, condor_q -l 12345 shows

     foo = "$(Cluster)"

unexpanded.
I cannot do the expansion before submission, because then $(Cluster)
is resolved as 1.
I have played trying to pass

      "+foo": ExprTree(' "$(Cluster)" ')

but then I get

     TypeError: No registered converter was able to produce a C++
rvalue of type std::string from this Python object of type ExprTree

If I try w/o the single quotes and only the double ones, then

     SyntaxError: Unable to parse string into a ClassAd.

What am I missing here?

Thanks
Jose
