NAME
Parse::or - Create a new parser which is the combination of the arguments.SYNOPSIS
Parser<a> or( Parser<a> x, Parser<a> y )ARGUMENTS
x The first parser
y The second parser
DESCRIPTION
Create a new parser combining x and y
The new parser recognises a string which is recognised by either x or y.
decimal = or(Parse::digit,Parse::char@('.'));
// may be more clear in many situations to write this as
decimal = Parse::digit `or` Parse::char@('.');
As with Kaya's || operator, this uses short-circuit evaluation: if x parses the String successfully, y will not be used.
