Re: [swift-evolution] Shortcut for creating arrays

[Radosław Pietruszewski via swift-evolution]

FWIW, in Swift 3:

“h j c k”.componentsSeparated(by: “”)

or 

“h j c k”.componentsSeparatedByCharacters(in: .whitespace())

which is slightly better.

Regarding the proposal, I love Ruby’s %w(foo bar) and other nice shortcuts like 
that, but short-term I think we have bigger problems in Swift.

I would love if we had a macro system that would allow something like this, 
though.

Yes, we should have words.split() at some point.  IMO this is in scope
for a redesign of strings that is expected, but not on the immediate
horizon.

Re: [swift-evolution] Shortcut for creating arrays

[Vladimir.S via swift-evolution]

As I understand in initial message, string should be splitted by spaces, 
not all kind of whitespaces(like TAB). whiteCharacterSet() is not just 
space(at least TAB char there too).
So, if we need split just by space we need some 
componentsSeparatedBySpaceCharacter(). And IMO this is not a good solution.


Actually "a b c".componentsSeparatedByString(" ") works well, but probaly 
it will be good to have something like
"a:b-->c/d".componentsSeparatedByStrings(":", "-->", "/"). But I'm not sure 
about this :-)

'componentsSeparatedByWhitespace' might be a nice addition as a shortcut
for that though?

 Well, you can do this already:
 let words = "rats live on no evil star".componentsSeparatedByString(" ")
 so I don't know how much a shortcut is needed.

 And given '%w' would currently be impossible in Swift as an operator
 containing a letter, is there a Swiftier function name or operator for 
 this?

Also thought about componentsSeparatedByString, clearly says what we have, 
what we do and what will have in result.

So I'm -1 for special command for such word array.

Pehaps we could have a function that splits by whitespace.

Well, you can do this already:
let words = "rats live on no evil star".componentsSeparatedByString(" ")
so I don't know how much a shortcut is needed.

And given '%w' would currently be impossible in Swift as an operator
containing a letter, is there a Swiftier function name or operator for this?

[swift-evolution] Shortcut for creating arrays

[Arsen Gasparyan via swift-evolution]

Hey guys,

Very often we need to create an array strings. It's a routine task and I
really like shortcut in Ruby that shortcut makes everyday coding a little
bit easier and fun:

   words = %w[rats live on no evil star]

What do you think about adding something like this in Swift?

Cheers,
Arsen
