Build parameters from enviromental variables

[Livia Barazzetti]

Hi, 

I recently started  using Sumatra and I like very much its functionality. I am trying the parameters functionality. In my python script I use 

parameters = sumatra.parameteres.build_parameters(parmeters_file)

Is it possible to build (or update) the parameters with the value of some enviromental variables? 

Thank you

Best Regards

Dear Livia,

Many apologies for not replying sooner. This somehow slipped by during my summer vacation.

Yes. All the Sumatra `ParameterSet` subclasses behave in many ways like normal Python dictionaries. So for example you could do:

  parameters.update(home=os.environ['HOME'], path=os.environ['PATH'])

or equivalently

  parameters.update({'home': os.environ['HOME'], 'path': os.environ['PATH']})

Best regards,

Andrew
