set the channel topic: IntelliJ Tips & Tricks for Kotlin K development

cmd + u = Go to super class cmd + option + b = Go to class implementations

useful when dealing with interfaces or extending classes

Yep, those are all useful, also when working with Java 🙂

Which ones are your favorites regarding Kotlin?

Another one I find really helpful in Kotlin: You can add names to all arguments of a constructor / function by selecting ‘Add names to call arguments’:

Another one: wondering how the syntax of something is? E.g. you want to create a new method/ extension function / operator function? You can just write that code, type

Alt + Enter

on that error, and let IntelliJ figure our the syntax for you:

I was about to post "Introduce object destructuring", but that doesn't seem to be an option for Kotlin (I've used it before but for TS)

@Alex that’s actually really cool! I just tried it out by having a data class, creating a new variable for it, and if I press

Alt + Enter

I get the option you mentioned:

ah, sweet! Not sure why I didn't see the option when I just quickly tried it

And this results in:

I love it! Thanks a lot, I didn’t know about this option 🎉

@here I collected all the tricks I could find and put it up on GitHub: https://github.com/mreichelt/kotlin-talk-intellij-tricks Maybe this is helpful to some of you! 😊

Is IntelliJ able to complete the name and type both same time? Every time I choose a name and the corresponding type I still need to specify the type manually which is annoying..

Hey guys. So there are these helper generators for classes like

generate constructor

and

generate hashcode

Is there any way to write a custom generator?

Not sure to whom it will be interesting, but you could use IDEA diff to see diff in files between branches without loading the whole project into IDEA:

git show origin/master:path/to/file > /tmp/master_file && idea diff /tmp/master_file path/to/file

Is there a shortcut to extract a dependency version from a <dependency> and create it as a property in <properties>?

Is there a way when using split view to force the width of the tab to be 120 chars or 80 chars. i find it a bit annoying to have to resize the tab sizes when i change the intellij window

Anyone know how I can make intellij find classes generated by apache cxf?

Anyone know how to not have generated files come up when searching via cmd shift f or cmd shift o in intellij?

Say, I have a

data class C(val x: X, val y: Y, val z: Z)

, and I want to create an instance. When I write something like

val c = C(

is there a shortcut how intellij includes all members with names? Like

val c = C( x = |, y = , z = )

(where

|

is the cursor position)

Hmm, that I don’t know - I’d love that, too. Maybe someone else here in this channel knows?

Hey folks! Wanted to check if there's a way to provide wildcard matching in the

codeInsightSettings.xml

file instead of providing providing each class or package? My use case is that I want to avoid certain methods from showing up in auto complete if their names have a certain suffix. Is there a way to do that somehow?

I just wanted to start a question, and then found the answer myself.. but it is not super obvious I think, so: If you want to search for primary constructor invocations you can command-click (don't know what it is on other platforms) on the parentheses around the short notation :)

Hey folks! https://www.jetbrains.com/help/idea/saving-project-as-template.html I think idea has a feature where you can save your existing project as template and you can create a new project out of this and looks like they have support for variables. Although the doc is not very in depth. Anyone using this feature? Or any other alternative where I can quickly create a project with some template strings out of an existing project

hey y'all, is there any shortcut for switching between active editor panes? If I split my editor into 3 or 4 (maybe even vertically!) I couldn't find any way to say 'move to the editor below current' using Action finder (CMD/CTRL+SHIFT+A). Is it possible?

Hey folks! Please how do I highlight multiple occurrences of a text in IDEA? (Similar to VS Code's Ctrl D)

I have a method that is totally redundant to call multiple times. Think

doResetWithValue(5)
doResetWithValue(5)

but with less obvious names. Is there a way to get an inspection warn me about this pattern? Similar to "redundant assignment" but with my method.

Hi! How can I highlight same occurrences of a text? (e.g. in vscode, I can highlight the text and press Ctrl+D to find same occurrences).

Is there a way to hide a kotlin public property in an API from intellisense? Possibly I should ask in #C8C4JTXR7
