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.

BUGS/TODOS

Currently subexpression (map/grep/usort) doesn't work yet.

ATTRIBUTES
