How can I interpret escape sequences in a multiline scala string?
escaping, multiline, scala, string-interpolation
Solution
Two options that I can think of:
You can use `StringContext.treatEscapes` directly:
StringContext.treatEscapes("""I want to be able to
|have the convenient formatting of a multiline string,
|while using inline escape sequences\r\r\b\\
|
|How can this be done?""".stripMargin)
If the variable substitution feature of the "simple interpolator" (`s`) isn't disruptive to your needs, then try combining string interpolation (which converts escaped characters) with `"""`-quotes (which doesn't escape ...):
println("""he\\lo\nworld""")
println(s"""he\\lo\nworld""")
outputs
he\\lo\nworld
he\lo
world
For details, see the relevant SIP and this earlier question.
Problem
In a nutshell: ``` """I want to be able to |have the convenient formatting of a multiline string, |while using inline escape sequences\r\r\b\\ | |How can this be done?""".stripMargin ```
