test PRISM input models

[xhajnal]

Only a few models were tested, and parser may fail with even correct models since PRISM does not have a grammar of model structure

You can use stormpy for this purpose. For example

import stormpy
try:
    prism_program = stormpy.parse_prism_program(prism_model_file)
except Exception as ex:
    print(f"Error parsing prism program {ex}")

change too broad Exception to the proper one

Thanks.
Do you mean for testing or for the feature?
Because to use it as a feature I need some additional dependencies over Storm, which I have failed to install on the VM for Artefact Evaluation.

TBD trace report of the Stormpy build error (currently unavailable)

i meant for testing if PRISM input models is syntactically valid.

Because to use it as a feature I need some additional dependencies over Storm, which I have failed to install on the VM for Artefact Evaluation.

If you need to use Stormpy, you need Storm in the first place. Once Storm is installed and registered in the system library path, you can use Pipenv and add the following line
stormpy = {editable = true, git = "https://github.com/moves-rwth/[email protected]"}
Installing Storm is afaik just follow the document, the trick is to use a manually installed boost 1.64. Otherwise, storm wont compile
