NAME

Language::Expr::Interpreter::Default - A default interpreter for Language::Expr

VERSION

This document describes version 0.23 of module Language::Expr::Interpreter::Default (in distribution Language-Expr), released on 2014-05-01.

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.

    Comparison like '1 > 1' and '

  • 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.
