java - How to de-escape string in scala? -


i found many posts escaping string no de-escaping one.

using scala play, controller accept json request. extract string via:

val text: play.api.libs.json.jsvalue = request.body.\("source")

if print text.tostring e.g.

"hello\tworld\nmy name \"abc\""

how can transform escaped text normal one? result should like

hello    world name "abc"

up point, i've tried approach follows:

replaceall("""\\t""", "\t")

however, creating possible escaping rules may complicated. question is: how easily? possibly using standard library. java solutions possible.

there interpolations allow transform strings formatted and/or escaped sequences. these interpolations s"..." or f"..." handled in stringcontext.

it offers reverse function:

val es = """hello\tworld\nmy name \"abc\"""" val un = stringcontext treatescapes es
