Word completion for the eric4 shell
This version is a re-implementation of rlcompleter as found in the Python3 library. It is modified to work with the eric4 debug clients.
This requires the latest extension to the readline module. The completer completes keywords, built-ins and globals in a selectable namespace (which defaults to __main__); when completing NAME.NAME..., it evaluates (!) the expression up to the last dot and completes its attributes.
It's very cool to do "import sys" type "sys.", hit the completion key (twice), and see the list of names defined by the sys module!
Tip: to use the tab key as the completion key, call
readline.parse_and_bind("tab: complete")
Notes:

Completer([namespace]) -> completer instance.
If unspecified, the default namespace where completions are performed is __main__ (technically, __main__.__dict__). Namespaces should be given as dictionaries.
Completer instances should be used as the completion mechanism of readline via the set_completer() call:
readline.set_completer(Completer(my_namespace).complete)
Protected method to check for a callable.
Compute matches when text contains a dot.
Assuming the text is of the form NAME.NAME....[NAME], and is evaluatable in self.namespace, it will be evaluated and its attributes (as revealed by dir()) are used as possible completions. (For class instances, class members are are also considered.)
WARNING: this can still invoke arbitrary C code, if an object with a __getattr__ hook is evaluated.
Return the next possible completion for 'text'.
This is called successively with state == 0, 1, 2, ... until it returns None. The completion should begin with 'text'.
Compute matches when text is a simple name.
Module function to retrieve the class members.
