Only when you call scope.extract():

   working_phil = working_phil.fetch(parse('parameter.toy=foo'))    working_phil.show()

params = working_phil.extract() Traceback (most recent call last): File "tst.py", line 17, in <module> params = working_phil.extract() File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 1677, in extract value = object.extract(parent=result) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 1677, in extract value = object.extract(parent=result) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 1073, in extract return self._type_from_words()(self.words, master=self) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 314, in from_words value = self._value_from_words(words=words, path=master.full_path()) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 332, in _value_from_words return int_from_words(words=words, path=path) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 262, in int_from_words result = number_from_words(words=words, path=path) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 221, in number_from_words value_string=str_from_words(words), words=words, path=path) File "/Users/nat/phenix/src/cctbx_project/libtbx/phil/__init__.py", line 217, in number_from_value_string path, value_string, format_exception(), words[0].where_str())) RuntimeError: Error interpreting parameter.toy="foo" as a numeric expression: NameError: name 'foo' is not defined (input line 1) -Nat

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 Ralf On Wed, Apr 11, 2012 at 6:48 AM, wrote:

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 }
