NAME
Language::Expr::Interpreter::default - A default interpreter for Language::Expr
VERSION
This document describes version 0.29 of Language::Expr::Interpreter::default (from Perl distribution Language-Expr), released on 2016-07-03.
SYNOPSIS
use Language::Expr::Interpreter::default;
my $itp = Language::Expr::Interpreter::default->new;
$itp->vars->{a} = 'A';
say $itp->eval(q["$a b" . "c"]); # "A b c"DESCRIPTION
Interprets Language::Expr expression. Some notes:
Uses boolean module.
Follows Perl's notion of true and false.
That is, this expression ' "" || "0" || 2 ' will result to 2 because Perl thinks "" and "0" are false.
