Pegex::Input - Pegex Parser Input Abstraction
use Pegex; use Pegex::Input; my $ast = pegex($foo_grammar) ->parse(Pegex::Input->new(string => $foo_input));
Pegex::Parser parses input. The input can be a string, a string reference, a file path, or an open file handle. Pegex::Input is an abstraction over any type of input. It provides a uniform inteface to the parser.
You call new() with two arguments, where the first argument is the input type:
Pegex::Input->new(file => 'file.txt')
The following input types are available:
Input is a string.
Input is a string reference. This may be desirable for really long strings.
Input is a file path name to be opened and read.
Input is from a opened file handle, to be read.
