+Pure logic and validation class.
+
+By using a Subject object, and a dict of described logic tests, it
+is possible to arrive at a True or False result for various purposes:
+1. Data validation
+2. UI control visibility
+
+A Subject can be any object whose members are readable with getattr() :
+class Subject(object):
+ a = 0
+ b = 1
+ c = 'foo'
+ d = True
+ e = False
+ f = 8
+ g = 'bar'
+
+
+Tests are described thus:
+
+Use the special list types Logic_AND and Logic_OR to describe combinations
+of values and other members. Use Logic_Operator for numerical comparison.
+
+# With regards to Subject, each of these evaluate to True:
+TESTA = {
+ 'a': 0,
+ 'c': Logic_OR([ 'foo', 'bar' ]),
+ 'd': Logic_AND([True, True]),
+ 'f': Logic_AND([8, {'b': 1}]),
+ 'e': {'b': Logic_Operator({'gte':1, 'lt':3}) },
+ 'g': Logic_OR([ 'baz', Logic_AND([{'b': 1}, {'f': 8}]) ])
+}
+
+# With regards to Subject, each of these evaluate to False:
+TESTB = {
+ 'a': 'foo',
+ 'c': Logic_OR([ 'bar', 'baz' ]),
+ 'd': Logic_AND([ True, 'foo' ]),
+ 'f': Logic_AND([9, {'b': 1}]),
+ 'e': {'b': Logic_Operator({'gte':-10, 'lt': 1}) },
+ 'g': Logic_OR([ 'baz', Logic_AND([{'b':0}, {'f': 8}]) ])
+}
+
+# With regards to Subject, this test is invalid
+TESTC = {
+ 'n': 0
+}
+
+# Tests are executed thus:
+S = Subject()
+L = Logician(S)
+L.execute(TESTA)
