Yes, at least when PETSc runs in verbose mode. That can be done by passing the -info command-line argument to PETSc. :-) > Or is it the dolfin part of the parameter system that does not get to parse > the parameter correctly? My fault. This is not a bug. I got confused as to what the demo is actually doing. I used another test program when I tested the command-line parsing for PETSc in C++. The "problem" is that the command-line is parsed by application_parameters, not by dolfin::parameters and options are only filtered out for PETSc for the global parameter set, not for other parameters like application_parameters. The following works fine: python -c "from dolfin import *; parameters.parse()" --petsc.info I'm closing the bug. By the way, very nifty with parameters.foo = 1.0 etc instead of parameters["foo"] = 1.0. :-) -- Anders -- Handle PETSc command-line options in Python https://bugs.launchpad.net/bugs/425282 You received this bug notification because you are subscribed to DOLFIN. Status in DOLFIN: Invalid Bug description: PETSc command-line options like --petsc.foo 3 are not handled in Python: StandardError: unknown option petsc.info Don't know why this doesn't work in Python since the Python interface seems to call the C++ implementation which handles PETSc command-line options. _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@fenics.org http://www.fenics.org/mailman/listinfo/dolfin-dev
