Is there a way to create heap dump, get shallow/retained/deep object size and so on while hanging on a breakpoint?

basic memory profiling analysis is introduced in IJ 2017.1

Thank you, I'll try

in the repl, whenever I create a new object in the heap, does it get assigned to a variable name like it’d do in a Scala repl? Posted in #general

or does it require to declare it explicitly using val?

is there a way to set a breakpoint immediatelly after a statement? usually i want to check the result of a statement but it's at the end of a func. so i have to add something stupid like val a=2 and set a breakpoint on that because that's the easiest way

I was getting errors about Java 5 language level. Set 7 everywhere in Project Structure and Settings. Getting problem with 'diamond' (

new TreeSet<>()

)

Wrong 1st argument type. Found: java.util.TreeSet<java.lang.Object>, required: java.util.Set<java.lang.Long>

And where are these memory tools? Can't find any mentions in the blog. Actually, new IDEA looks faster, has better icons, and I really like parameter name badges. ❤️ 4 replies Actually, this not helped. I've got Oracle Java 1.8.0_121 as project SDK, Java 7 as Project language level, 1.7 as Project Bytecode Version, and

sourceCompatibility = 1.7

in build.gradle. Compiler continues treating

new TreeMap<>()

as

new TreeMap<Object>()

.

Hey all, I have a bizarre IntelliJ issue, I’m not sure whether it’s Kotlin specific. I can’t type ‘K’ (shift+k) in an editor, it just doesn’t work. It’s not a hardware problem, it works fine everywhere else (including Intellij’s Terminal). Anyone have any idea what this could be, or how I could debug it?

Please check if you accidentally have a binding in keyboard shortcut for this key.

@orangy I set it back to the default keymap for OSX, still have the problem 😞

Ah! It’s set to “Find detached Kobalt project” - I’m off to #kobalt 🙂

I tried updating the kotlin plugin to latest version, and it saud that update failed. Now when loading the IDE I get an exception:

Resource not found in classpath: kotlin/coroutines/coroutines.kotlin_builtins
java.lang.IllegalStateException: Resource not found in classpath: kotlin/coroutines/coroutines.kotlin_builtins

How can I update the plugin? When the update failed it showed me directory with logs, but there are many of them and I don't know which one is relevant.

it dooesn't even find any updates now

And when trying to open any file with kotlin code it just keeps loading forever

ok, I reinstalled the plugin and it works

guys is there something like this for kotlin?

@mingkangpan You don't really need a refactoring for this in Kotlin, as you don't need to touch external code. You can simply convert this:

class Class(s: String)

class AnotherClass {
    fun method() {
        val aClass = Class("string")
    }
}

to this:

class Class {
    companion object {
        operator fun invoke(s: String): Class {
            return Class()
        }
    }
}

class AnotherClass {
    fun method() {
        val aClass = Class("string")
    }
}

Notice that

AnotherClass

hasn't changed at all.

@User uploaded a file: and commented: I've added Firebase deps automatically, by clicking a button, and my deps messed up (look at VCS bars on the left). Is it Firebase Plugin’s or IDEA’s problem?

anything that touches gradle files has the potential to mess something up

that's the consequence of using a dynamically typed language

if you don't know the type of anything, you're basicly doing text replacement

Yeah I really want to use gradle script kotlin.. is it significantly better in its present state?

I'm kinda afraid if I move my android project to it it'll break all the things

Android seems more brittle than anything

if it works, it works. but getting there is a bit tedious

sometimes IDE support breaks, sometimes you have to restart the IDE so that the correct types are resolved

and you have to do a lot of searching for the correct extension/convention type
