[ZScript] isnot keyword?

[kevansevans]

It's just some syntax sugar, because

Code: Select all

if (mo isnot "MyCoolActor")

looks better than

Code: Select all

if (!(mo is "MyCoolActor"))

Would make it compliment to == and !=

I'd be willing to implement this myself if it gets a "yes"

[phantombeta]

I personally don't see any reason not to have this, if implemented correctly it'd just be syntactic sugar for !(x is y) anyway.
IMO x !is y or x is not y would be better, though.

x !is y or x is not y

both of those would require significant changes, due to how zscript parses operations (isnot wouldn't require them -- it follow the same rules as any other operation like is)

I've wanted this also. No functional difference, just code that is slightly easier to read/write

x !is y or x is not y

Actually, they wouldn't require much of a change at all. Have you seen how ZScript does 'static const'?
All it does is combine both tokens to one before passing it to the grammar parser, so you could do the same with '!is'.
