Which setting to avoid breaking up a long string where it adds a line break within ${..}?

[tanin47]

It seems scalafmt tries to adhere to the max column by breaking up a long string line like below:

"something ${
somevariable.member
} something else"

I don't want it to do that. However, in other scenarios, I still want scalafmt to adhere to the max column settinng.

I can't seem to find a setting to prevent this. I wonder if scalafmt supports this.

Thank you!

I think the only thing you could do currently is:

   // format: off
   val s = s"something ${somevariable.member} something else"
   // format: on

or breakup those strings yourself since maxColumn doesn't make much sense if you actually only want it in some cases.

I now use it to avoid and it works!

is there some way we can improve the documentation to empower people to find what they are looking for? this setting was documented, after all.

I had it set to oneline because I thought oneline meant "keeping it in oneline"; It turns out "oneline" means it'll break the line.

I probably was aware of this setting but forgot. Then, I continued seeing that the format wasn't what I wanted (for months now).... so I eventually came here to ask the question.

I hope this is helpful.

Interestingly enough I tried LLMs as a fallback on the config page and it didn't manage to find it. Maybe we could create an LLM friendlier version to make it easier for people to get the config they want.
