+Class and program to colorize python source code for ANSI terminals.

+
+Title: Colorize Python source using the built-in tokenizer
+
+Submitter: Jurgen Hermann
+Last Updated:2001/04/06
+
+Version no:1.2
+
+Description:
+
+This code is part of MoinMoin (http://moin.sourceforge.net/) and converts
+Python source code to HTML markup, rendering comments, keywords,
+operators, numeric and string literals in different colors.
+
+It shows how to use the built-in keyword, token and tokenize modules to
+scan Python source code and re-emit it with no changes to its original
+formatting (which is the hard part).

+ the Struct S, the optional dictionary 'conflict' is used to decide
+ what to do.
+
+ If conflict is not given, the default behavior is to preserve any keys
+ with their current value (the opposite of the :meth:`update` method's
+ behavior).
+
+ Parameters
+ ----------
+ __loc_data__ : dict, Struct
+ The data to merge into self
+ __conflict_solve : dict
+ The conflict policy dict. The keys are binary functions used to
+ resolve the conflict and the values are lists of strings naming
+ the keys the conflict resolution function applies to. Instead of
+ a list of strings a space separated string can be used, like
+ 'a b c'.
+ **kw : dict
+ Additional key, value pairs to merge in
+
+ Notes
+ -----
+ The `__conflict_solve` dict is a dictionary of binary functions which will be used to
+ solve key conflicts. Here is an example::
+
+ __conflict_solve = dict(
+ func1=['a','b','c'],
+ func2=['d','e']
+ )
+
+ In this case, the function :func:`func1` will be used to resolve
+ keys 'a', 'b' and 'c' and the function :func:`func2` will be used for
+ keys 'd' and 'e'. This could also be written as::
+
+ __conflict_solve = dict(func1='a b c',func2='d e')
+
+ These functions will be called for each key they apply to with the
+ form::
+
+ func1(self['a'], other['a'])
+
+ The return value is used as the final merged value.
+
+ As a convenience, merge() provides five (the most commonly needed)
+ pre-defined policies: preserve, update, add, add_flip and add_s. The
+ easiest explanation is their implementation::
+
+ preserve = lambda old,new: old
+ update = lambda old,new: new
+ add = lambda old,new: old + new
+ add_flip = lambda old,new: new + old # note change of order!
+ add_s = lambda old,new: old + ' ' + new # only for str!
+
+ You can use those four words (as strings) as keys instead
+ of defining them as functions, and the merge method will substitute
+ the appropriate functions for you.
+
+ For more complicated conflict resolution policies, you still need to
+ construct your own functions.
+
+ Examples
+ --------
+ This show the default policy:
+
+ >>> s = Struct(a=10,b=30)
+ >>> s2 = Struct(a=20,c=40)
+ >>> s.merge(s2)
+ >>> sorted(s.items())
+ [('a', 10), ('b', 30), ('c', 40)]
+
+ Now, show how to specify a conflict dict:
+
+ >>> s = Struct(a=10,b=30)
+ >>> s2 = Struct(a=20,b=40)
+ >>> conflict = {'update':'a','add':'b'}
+ >>> s.merge(s2,conflict)
+ >>> sorted(s.items())
+ [('a', 20), ('b', 70)]
+ """
+
+ data_dict = dict(__loc_data__,**kw)
+
+ # policies for conflict resolution: two argument functions which return
+ # the value that will go in the new struct
+ preserve = lambda old,new: old
+ update = lambda old,new: new
+ add = lambda old,new: old + new
+ add_flip = lambda old,new: new + old # note change of order!
+ add_s = lambda old,new: old + ' ' + new
+
+ # default policy is to keep current keys when there's a conflict
+ conflict_solve = dict.fromkeys(self, preserve)
+
+ # the conflict_solve dictionary is given by the user 'inverted': we
+ # need a name-function mapping, it comes as a function -> names
+ # dict. Make a local copy (b/c we'll make changes), replace user
+ # strings for the three builtin policies and invert it.
