A Scala String chomp (or chop) function

Scala string FAQ: Does Scala have a String method like chomp or chop that you find in Perl?

If you're using Scala and want a string chomp or chop method that you're used to in languages like Perl to remove end of line characters, the stripLineEnd method will do what you want, as shown in the REPL:

scala> val a = "foo\n"
a: String = 
"foo
"
scala> a.stripLineEnd
res0: String = foo

scala> val b = "bar"
b: String = bar

scala> b.stripLineEnd
res1: String = bar

This method can be found in the Scala StringOps class, which you can find here:

• http://www.scala-lang.org/archives/downloads/distrib/files/nightly/docs/library/index.html#scala.collection.immutable.StringOps

Note that this behavior is different than the trim method on the String class, which trims blank spaces from the beginning and end of a string.

You can also use stripLineEnd to define your own chomp or chop function, like this:

def chomp(s: String) = s.stripLineEnd

You can then call the function with a String, like this:

scala> chomp(a)
res2: String = foo

scala> chomp(b)
res3: String = bar

If you're looking for a Scala String chop/chomp method, I hope this has been helpful.
