Hi Graeme,

If you add

working_phil.extract()

you'll get:

Error interpreting parameter.toy="foo" as a numeric expression: NameError: name 'foo' is not defined (input line 1)

We also have this:

   proxy = working_phil.get("parameter.toy").objects[0].validate("0")
   print proxy.error_message
   print proxy.extracted

… is there any?

This does not give an error:

from libtbx.phil import parse

working_phil = parse("""
parameter {
 toy = 10
   .type = int
}
""")

if __name__ == '__main__':
   working_phil.show()

   # this should crash right?
   working_phil = working_phil.fetch(parse('parameter.toy=foo'))

   working_phil.show()

Output:

cctbx.python toy_phil.py
parameter {
 toy = 10
}
parameter {
 toy = foo
}

Thanks,

Graeme
