# Build An Initial Symbol Table #
#---------------------------------------------------------------------------#
# One of the options of this test driver is to initialize a test symbol
# table. We build that table here in case the user requested it.
# Create An Empty Symbol Table
symtbl = {}
# This test driver makes it easy to add pre-defined symbols of
# your own choosing. The first way is like this ...
# The data below is used to populate an initial symbol table. You can add or
# change things here without modifying any of the following code.
# Each symbol has an entry which is a list with the following items:
#
# Name, Value, Writeable, Type, Default, LegalVals, Min, Max
#
# Where 'None' appears, the init code just uses the default established
# by the VarDescriptor base class.
syms = [ ["foo", 1, True, TYPE_INT, 0, [1, 2, 23], 1, 30 ],
["fox", 1.0, None, TYPE_FLOAT, 0.5, [3.14, 2.73], None, None ],
["bar", "stringy", None, None, None, [r'^box$', r'^Bax', r'a+bc'], 3, 8 ],
["baz", 4+5j, None, TYPE_COMPLEX, 0-0j, [], None, None ],
["boo", True, None, TYPE_BOOL, None, None, None, None ],
["read", "ReadVar", False, None, None, None, None, None ],
]
# Another way to add pre-defined symbols is to explicitly load
# them into the symbol table. The example below does this as
# well as demonstrating how to use inheritance to create
# your own types derviced from the tconfpy variable descriptor
# base class.
# Here's a way to inherit the base symbol definition from
# the module and then derive a new object type for your
# own convenience
# Note the use of 'super()' here to run each constructor in
# the inheritance tree only once.
