Unfortunately it is not visible through the tab-completion in ipython, as that commando use the __dict__ attribute for this, and not __get/setattr__ commands. In python < 3.0 there are a lot of different ways of setting attributes... each with different preference and behavior.

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 [email protected] http://www.fenics.org/mailman/listinfo/dolfin-dev
