String Interpolation with 'raw'
In the following lesson, you will be introduced to the 'raw' string interpolator.
We'll cover the following
The raw string interpolator is similar to the s interpolator. The only difference is that raw doesn’t recognize character literal escape sequences.
The raw String Interpolator
For string interpolation with raw, we prepend the word raw to any string literal. This allows us to print characters symbols within strings.
println("Without Raw:\nFirst\nSecond")println(raw"With Raw:\nFirst\nSecond")
Syntax
In the example above, raw"With Raw:\nFirst\nSecond" is the processed string literal. \n is the escape sequence which is used to take the string to the next line. When we don’t use the raw interpolator, the output is as expected; the word First and Second are on different lines. However, when we do use the raw interpolator, the compiler prints the escape sequence \n as is.
You can try the above code with any escape sequence you want.
This brings our discussion on string interpolation to an end. Let’s now look at some common String problems and see how we can solve them using Scala.
