smartDedent(paragraph)

Dedent paragraph using textwrap.dedent(), but properly dedents even if the first line of paragraph does not contain blanks. This handles the case where a user types a documentation string as

‘’’A long string spanning several lines.’’’

---

stringize(topicName)

If topicName is a string, just return it as is. If it is a topic definition object (ie an object that has ‘msgDataSpec’ as data member), return the dotted name of corresponding topic. Otherwise, assume topicName is a tuple and convert it to to a dotted name i.e. (‘a’,’b’,’c’) => ‘a.b.c’. Empty name is not allowed (ValueError). The reverse operation is tupleize(topicName).

---

tupleize(topicName)

If topicName is a tuple of strings, just return it as is. Otherwise, convert it to tuple, assuming dotted notation used for topicName. I.e. ‘a.b.c’ => (‘a’,’b’,’c’). Empty topicName is not allowed (ValueError). The reverse operation is stringize(topicNameTuple).

---

validateName(topicName)

Raise TopicNameError if nameTuple not valid as topic name.
