case-insensitive-string-set 1.1.0

A set class for case-insensitive strings.

Case-insensitive string set

A Python package providing an ordered set class for case-insensitive strings.

Useful for doing things like foo in bar where bar is a set of strings and you want the check to be case-insensitive, but also preserve the original casing of the strings in the set when iterating over it.

Inside the CaseInsensitiveStringSet class, a dictionary is used to store the data, which means that insertion order is preserved in Python >= 3.7.

Examples

>>> c = CaseInsensitiveStringSet()
>>> c.add("a")
>>> 'a' in c
True
>>> 'A' in c
True
>>> 'b' in c
False
>>> list(c)
['a']
>>> c.add("A")
>>> list(c)
['a']
