When overriding an

abstract val

, do you tend to just assign the value or use

get() =

assuming it is very fast to calculate (e.g. returning a const)?

(or any insight would be appreciated)

is there any reason to use kotlin expressions over a function other than aesthetics? eg:

fun getANumber() {return 2}  or fun getANumber() = 2

No, it's just syntax sugar.

ok

but don’t underestimate the value of aesthetics

I'd say conciseness (sp?) instead of aesthetics 🙂

tangential note, if you use the expression body format, you can omit the return type, which can be convenient, but potentially problematic if you ever find yourself changing the line and accidentally changing the return type of that function

How does kotlin String.indexOf handle line endings?

In what sense?

for example if I have

"\r\nthing\r\n".indexOf("\nthing\n")

, will it find that or not?

for me it doesn't seem to, but for some other people it appears to work (on different OS)

Line-break characters should behave just like any other character

well, at least I don't have other explanation for why an exception isn;t thrown

An exception?

because indexOf returns negative number and it then breaks code later

indexOf()

returns

-1

if your search criteria isn’t found

I get the exception, the developer of that code doesn't

The only other explanation is that either Gson is doing something weird with line endings, or github API is inconsistent

and since he is apparently on mac, I can't test that myself

fwiw your example doesn’t work for me on macOS

meaning it returns -1?

correct

it cannot find

\nthing\n

within

"\r\nthing\r\n"

And actually, how could indexOf return -5?

oh nvm, it doesnt

it does return -1

I guess then githhub API is somehow inconsistent

Your example can never return anything but -1, because

\nthing\n

does not occur in your haystack.
