I think it'd be neat if Intellij could recommend making a function inline. I find it hard to know when to do so.

I would do it in special cases only, JIT is already inlining at runtime.

Most of the time you don't want to inline functions, because it messes with the JIT's optimization procedures. There are a few exceptions, mostly dealing with lambdas and crossinline lambdas, and my experience is that IDEA does give hints in those situations.

orite... i'm ashamed to say i honestly can't conceive of such a special case

[Hullaballoonatic]

i think the only time i ever use inline is when it is impossible to write the function otherwise (iirc), or i'm modelling a function off a stdlib one

[dalexander]

I would guess those are more or less the correct situations 🙂

[Shawn]

the rule of thumb I’ve used is either a) reified or b) takes a lambda

[Dominaezzz]

Unless you're in Kotlin/Native I guess.

Or on Android, where lambda allocation is costly, and where R8 can spot code duplication and make a method to reduce output size too.
