12/12/2015, 8:35 PMis there a concise equivalent of java’s try-with-resources in kotlin? - d
dharrigan
12/12/2015, 8:35 PMI'm trying to port a very very small standard java backend service to Kotlin as an experiment, so I have a few classes that are very very akin to data classes - d
dharrigan
12/12/2015, 8:36 PMI could rewrite these (easily enough) to Kotlin data classes - j
jkwatson
12/12/2015, 8:36 PMthat’s what I would do. - d
dharrigan
12/12/2015, 8:36 PMbut just interested before I do that, if I can save time in not doing that simple smile - j
jkwatson
12/12/2015, 8:36 PMIf you’re going 100% pure kotlin, then moving to kotlin data classes is 100% better. - j
jkwatson
12/12/2015, 8:36 PMif you need interop, things get messy in a hurry where lombok is concerned. - d
dharrigan
12/12/2015, 8:37 PMI suppose you are right simple smile - d
dharrigan
12/12/2015, 8:37 PMMight as well do the conversion simple smile - j
jkwatson
12/12/2015, 8:37 PMunless you can put the lombok’d classes in another project/module that gets compiled with javac ahead of time. - j
jkwatson
12/12/2015, 8:37 PMthen kotlin just sees bytecode - o
orangy
12/12/2015, 8:38 PM@jkwatson: try-with-resources is currently implemented with
extension function. Doesn’t exist on AutoClosable though…use - j
jkwatson
12/12/2015, 8:40 PMthat works fine for me. Any reason why it’s not on AutoClosable? - o
orangy
12/12/2015, 8:40 PMJDK 6 compatibility - j
jkwatson
12/12/2015, 8:40 PMah. gotcha - o
orangy
12/12/2015, 8:40 PMWe are planning to work on JDK 8 and up after v1 - j
jkwatson
12/12/2015, 8:40 PMyep. - d
dharrigan
12/12/2015, 8:40 PMusing a kotlin data class rather than a lombokified java class is nicer simple smile - j
jkwatson
12/12/2015, 8:41 PMsince I’m not an android dev, java 6 feels very, very long ago. simple smile - j
jkwatson
12/12/2015, 8:41 PM@dharrigan: definitely what I found, too - o
orangy
12/12/2015, 8:41 PMI know simple smile On serverside I’m using Java 8 without much issues. Except for some functions like this, and File vs Path API, everything just works. - d
dharrigan
12/12/2015, 8:42 PMMan, I sincerely hope someone at Google listens to what @jw said in his tweet a couple of days ago - d
dharrigan
12/12/2015, 8:43 PM - d
dharrigan
12/12/2015, 8:43 PMI can't remember the last time I had to target pre java-8 code - d
dharrigan
12/12/2015, 8:43 PMexcept, of course, on Android. - d
dharrigan
12/12/2015, 8:47 PMsay you had a string, which you want to split, using string.split(","), and you want access to each part of the split, an idomatic way of getting those parts in Kotlin would look like? - p
phroa
12/12/2015, 8:59 PM@dharrigan: .forEach{} should do - d
dharrigan
12/12/2015, 9:00 PMta - p
phroa
12/12/2015, 9:03 PMor you could dofor (s in "hi there".split(" ")) { ... } - d
dharrigan
12/12/2015, 9:04 PMThat would help too simple smile Thank you.
