Indent-adjusted multiline string literals for Scala.
Copyright 2015 Dave Gurnell. Licensed Apache 2.
Add the following to your build.sbt:
libraryDependencies += "com.davegurnell" %% "unindent" % "<<VERSION>>"Unindent provides two new string interpolators for indented strings: i"..." and i1"...":
The i"..." interpolator is like Scala's s"...", except it removes the indent applied in the source file. The behaviour is similar to Coffeescript's multiline string literals:
import unindent._
val example =
i"""
This is an indented multi-line string.
This line ends up unindented.
This line ends up indented by two spaces.
It supports interpolation too: ${1 + 1}.
"""
println("[" + example + "]")
// [This is an indented multi-line string.
// This line ends up unindented.
// This line ends up indented by two spaces.
// It supports interpolation too: 2.]The i1"..." interpolator (added un Unindent 1.7) is like i"...", except it folds "paragraphs" of text into single lines. The behaviour is similar to YAML's folded multiline strings:
import unindent._
val example =
i1"""
This is the first line.
This line is appended to the first.
This line follows a line break.
This line ends up indented by two spaces.
"""
println("[" + example + "]")
// [This is the first line. This line is appended to the first.
// This line follows a line break. This line ends up indented by two spaces.]See the tests for more examples.
