11/02/2015, 9:54 AMI apologize, what I said is true, but for multi-lined string literals, i.e.
is the only way to getval price = """example ${'$'}9.99"""
in them$ - w

11/02/2015, 10:47 AMOh right. Well, I agree with you. $DS is nice. - k
kirillrakhman
11/02/2015, 11:05 AMI think the usecase is a small one and you can still define
yourselfDS - v
voddan
11/02/2015, 11:06 AMif everyone defines
on his own, how do you read such a code? Because it will beDS
,ds
,d
, etcD - k
kirillrakhman
11/02/2015, 11:07 AMlike I said, I believe this won't happen too often, therefore not everyone will define it - w

11/02/2015, 11:21 AMThis problem caused by the specification that only '$' is enabled in multi-lined string although '\' is not. I think both should be enabled, or both should be disabled. - o

class for special symbols, we could just add “dollar” thereTypography - u

11/02/2015, 11:55 AMI think this should be solved on the language level, e.g.

11/02/2015, 3:27 PMHi, is there any particular reason for bitwise xor not being available for Byte types? - y
yoavst
11/02/2015, 3:41 PMIf I remember right, in java it casts to int, do stuff, cast to byte - a
agatti
11/02/2015, 4:40 PM@yoavst: seems like you recall correctly, although it’s a bit of a chore to manually do the casting for that in Kotlin simple smile - k
kirillrakhman
11/02/2015, 6:09 PMyou can always write an extension function - v

11/02/2015, 6:10 PMByte.xor - a
agatti
11/02/2015, 6:31 PMTrue, I was just a bit baffled by this. The java->kotlin converter cannot really handle that and generates uncompilable code too. - a
agatti
11/02/2015, 6:31 PMThat’s why I ended up wondering what was going on simple smile - y
yoavst
11/02/2015, 6:34 PMYea, tried to convert base64 util class, ended up keeping it Java. - m
mikehearn
11/03/2015, 2:34 PMcouple of questions: - m
mikehearn
11/03/2015, 2:34 PMis there a method that removes elements matching a predicate from a mutable list and then returns them? - m
mikehearn
11/03/2015, 2:34 PMalso: is there a shorthand for seq.map { … }.filterNotNull()? seems it’d be more efficient to have them be combined - o
orangy
11/03/2015, 2:37 PMno remove method like you want, afaik - o
orangy
11/03/2015, 2:37 PMmap and then filter non-null is coming - o
orangy
11/03/2015, 2:38 PMfor remove you can usepartition - o
orangy
11/03/2015, 2:39 PMLike this:``` fun fn(list: List<String>) { val (less, more) = list.partition { it.length < 10 } } ``` - m
mikehearn
11/03/2015, 2:39 PMyes, thanks. looking at my code again, i think it’d be more efficient to just use a mutable counter actually. - m
mikehearn
11/03/2015, 2:39 PMas the thing i really care about is if the list is empty at the end - o
orangy
11/03/2015, 2:40 PMmutable counter? - o
orangy
11/03/2015, 2:40 PMmay be just
?list.count { … condition … } - o
orangy
11/03/2015, 2:40 PMor evenlist.all { } - m
mikehearn
11/03/2015, 2:41 PMwell, it’s a bit complicated. i have a set of input objects that map to zero or more output objects, and i want to ensure at the end that all the outputs are accounted for (there are none that had no input object working with them)
