----------------------------------
Summary: Create a SGM#next which also takes an integer increment
value
Key: GROOVY-11636
URL: https://issues.apache.org/jira/browse/GROOVY-11636
Project: Groovy
Issue Type: New Feature
Reporter: Paul King
Assignee: Paul King
Trying to get from String 'a' to 'e' by "adding 4" can be cumbersome, either
calling next() multiple times, or converting to a char, doing the arithmetic,
then converting back.
The idea would be to support:
{code:groovy}
assert 'a'.next(0) == 'a'
assert 'a'.next(4) == 'e'
assert 'a'.next(0) == 'a'
assert 'a'.next(25) == 'z'
assert 'A'.next(32) == 'a'
assert (0..4).collect('a'::next) == 'a'..'e'
assert 'car'.next(2) == 'cat'
{code}
Although hopefully never used, this piggybacks on the normal next() wrapping
behavior if Character.MAX_VALUE is reached. And also, like next(), applies the
the last character in a longer String as per last test above.
