formats the source code of programs. Alternative names are formatter or beautifier.
Pretty printers differ in the inputs they accept:
- The source text itself.
- A ParseTree that corresponds to the source text. This variant is also called unparser.
- An AbstractSyntaxTree that corresponds to the source text.
- The source language(s) they can accept.
- The adaptability of the formatting rules.
Examples The program fragment
if(x > 10) { System.err.println("x > 10"); } else { System.err.println("x <= 10"); }
can be pretty printed in many different ways. Here are two variants examples:
if(x > 10) {
System.err.println("x > 10");
} else {
System.err.println("x <= 10");
}
if( x > 10 )
{
System.err.println("x > 10");
} else
{
System.err.println("x <= 10");
}
