f interpolator rejects vertical bar followed by newline following interpolation %s|%n

[cayhorstmann]

Compiler version

3.0.0

Minimized code

val s = "Fred"
f"$s|%n"

Output

conversions must follow a splice; use %% for literal %, %n for newline. 

Expectation

"Fred|" followed by a newline

Thanks for the report. That is #9939 (comment) where %n consumes the preceding interpolation.

The VBAR is not special here. Without it, %n would swallow Fred.

I did some work on that PR, and will return to it shortly.

Closing as duplicate of #9939 then
