I was wondering if there is any way of preserving indentation while doing string interpolation in scala. Essentially, I was wondering if I could interpose my own StringContext. Macros would address this problem, but I’d like to wait until they are official.
This is what I want:
val x = "line1 \nline2"
val str = s"> ${x}"
str should evaluate to
> line1
line2
You can write your own interpolators, and you can shadow the standard interpolators with your own. Now, I have no idea what’s the semantic behind your example, so I’m not even going to try.
Check out my presentation on Scala 2.10 on either Slideshare or SpeakerDeck, as they contain examples on all the manners in which you can write/override interpolators. Starts on slide 40 (for now — the presentation might be updated until 2.10 is finally out).
