[cctbxbb] accessing attributes of PHIL parameters

[Billy Poon]

Hi Rob,

Yes, you can access those attributes, but you have to work with the phil
object, not the extract. Here is some sample code. There is more code in
the libtbx/phil/interface.py that builds some dictionaries for tracking
these values.

arrayinfo_phil_str = """
selected_info {
   span = True
     .type = bool
     .short_caption = "Span"
   minmax_data = True
     .type = bool
     .short_caption = "min,max data"
}
"""

def recursive_show(phil_object):
  for o in phil_object.objects:
    if o.is_scope:
      recursive_show(o)
    elif o.is_definition:
      # o.show()
      print('My name is', o.name)
      print('My value is', str(o.words[0]))
      print('My type is', str(o.type))
      print('My short_caption is', o.short_caption)
      print('My full path is', o.full_path())
      # print(dir(o))

from libtbx.phil import parse
p = parse(arrayinfo_phil_str)
recursive_show(p)
