A modern programming language that makes developers happier.

kotlinlang

Is it safe to use <https://kotlinlang.org/docs/strings.html#multi-dollar-string-interpolation|multi-dollar string interpolation> in libraries? I'm assuming this does not change the final jar/klib but figured I'd ask before enabling this everywhere.

Looking at decompiled Java code I would *guess* that it is safe, because
```val foo = "foo"
println($$"$foo $$foo")```
decompiles to
```String foo = "foo";
System.out.println("$foo " + foo);```
But :man-shrugging:

It seems like it's a frontend only transformation indeed

Regex-based syntax highlighters in shambles

Or text editors with Kotlin syntax but not a full-fledged parser

I would assume nearly all of them except anything based on tree-sitter

Even Kotlin's own docs that you linked are highlighted incorrectly

That's a good point. Maybe I can wait a bit

Curious how many will handle `$$` explicitly and not generically any amount of dollars :smile:
