fileToFoo

is defined on

File

?

If it's top level extension on file, then

File::fileToFoo

should work.

If it's just top level function taking

File

,

::fileToFoo

should work.

oh i see. no it's not..guess that's why then

If it's defined inside another class,

objectOfThatClass::fileToFoo

should work.

If it's defined as `File`'s extension function inside another class... then I don't know.

Hello, everybody! I just joined the Slack community, nice to meet everyone!

I'm having some difficulties with Dokka. When trying to generate Javadoc with gradle, I don't know how to link the JDK8 and kotlin-stdlib types and methods such that I won't have weird signatures like "java.lang.String" all over the place. Can anyone help me with this?

Go to #dokka channel

Thank's for the suggestion!

Hello! Suddenly the kotlin project in gradle started failing to compile - Failed to apply plugin [id 'kotlin'] For input string: “” Worked fine a few minutes ago.

Maybe some update?

@borboss seems like https://youtrack.jetbrains.com/issue/KT-17125

Is there any good explantion of how

@DslMarker

works? Readed docs several times and still cannot grok it.

kotlinx.html is a good example

a base type

interface Tag

for all tags is marked with this annotation

Have a generics puzzler, I want to define a function as follows:

inline fun <reified T : Any, E : Element> ElementCreator<E>.render(d : ElementCreator<E>.(T) -> Unit) {

When I call it I need to supply both type parameters, ie:

render<Entity.List, BodyElement> { it -> … }

Note that

this

will be an

ElementCreator<Something>

. My question is: why can’t the second type parameter

E

be inferred from the type of

this

, why do I need to supply it when I call

render

?

Because there is no such a feature as partially specified type arguments. You either omit all or none.

@orangy Ok, thanks - I’ll think on it a bit more, there might be another approach

@Ian you can try to chain functions, something like

creator.render<String>().using { }

@orangy Ah, good idea - thank you

hi Kotliners! Can you please sort a question for me

is there an equivalent of the static block in java that's loaded at initialization of the program, when loaded by the classloader

so far I've tried with objects and such, and their init block only gets called after the first time they're referenced

@orangy It worked! Thanks 🙂

render.with<Entity.List> { it ->

@pakoito can’t you use

object

and reference it at program start?

like here https://github.com/dbacinski/Design-Patterns-In-Kotlin#singleton

and reference it at program start

this is the tricky bit, I want to use it on a library

i think the same is in java when class is not referenced then static block is not called
