02/12/2019, 5:32 PMIs it possible to do an extension function with a function receiver? - d
dumptruckman
02/12/2019, 5:32 PMCause that would be so cool - d
dumptruckman
02/12/2019, 5:32 PMSeems like it ought to be possible since we have local functions - k

02/12/2019, 5:32 PMDoesn't it just work? - l

03/06/2019, 8:10 PMOr, for that matter, val v = 14 should also display as
with the hintval v: Int = 14 - l

Rafa
03/07/2019, 8:31 PMmy guess is that with the limit of functions in a class on the JVM being 65535, (I think?) then we know we have a max limit of 65535
functions that would be created. Vs. a list could have an infinite amount more propertiescomponent - m

03/07/2019, 8:44 PMIs there a quick way to see the full public API my Kotlin library project surfaces? So I can cross-check that nothing is public what shouldn't be 🙂 - j

03/07/2019, 8:46 PMyou can also use tools like metalava which is what the Android framework and AndroidX libraries use. JetBrains has a tool they use for the Kotlin stdlib and kotlinx libraries. - j

03/07/2019, 8:47 PMthose two dump a text file of signatures which you commit (and therefore can review) and will validate against it for binary incompatible changes - m
Marc Knaup
03/07/2019, 8:49 PMSo there are several command-line tools but no IDE-like inspection 🤔 That's a good start with room for improvement. I think I'll have to dig a little in all the codestyle & library authoring tools. Thanks! - p

03/07/2019, 11:43 PMdoes kotlin do lambda fusion? If I have
will it remove the unnecessary allocation?map { f(it) } - j

03/08/2019, 5:50 AMany good way to achieve something like a class delegate to a non-interface? i'm trying to extend ByteBuffer to create a custom 'Poolable' version (i want most code which uses it to be able to use it directly as a ByteBuffer without knowing about this poolable type), but would rather not have to re-implement all the abstract methods of ByteBuffer and have to pass through to the inner member - h

03/08/2019, 7:49 AMAlright, to answer my own question, this seems to work - h

03/08/2019, 11:33 PMnothing makes me love kotlin's safe navigation '?' operator like writing javascript does.... e.g. js:
kotlin:this.app.credentials && this.app.credentials.emailapp.credentials?.email - h
Hullaballoonatic
03/08/2019, 11:58 PMwhy in the world does javascript not incorporate that... - h
Hullaballoonatic
03/08/2019, 11:58 PMbut i guess that's too much to ask from a language that doesn't even have a
method.list.remove()
