Hi all,
The new parser(Parrot) supports negative relational operators now,
which is proposed by Guillaume Laforge :)
Here are some example
codes(https://github.com/danielsun1106/groovy-parser/blob/negativeRelationalOperators/src/test/resources/core/NegativeRelationalOperators_01x.groovy):
assert 'a' instanceof String
assert 'a' !instanceof Integer
assert 1 <= 2
assert 2 !<= 1
assert 2 >= 1
assert 1 !>= 2
assert 1 < 2
assert 2 !< 1
assert 2 > 1
assert 1 !> 2
assert 1 in [1, 2]
assert 3 !in [1, 2]
I think !instanceof and !in are ok. The others... not sure here. Right
now a<b uses the same method as a>=b, which means !< is >=. And in this
case I actually prefer >=.
