NAME

Text::Xslate::Manual::Debugging - Debugging techniques for Xslate templates

DESCRIPTION

This document describes techniques for debugging templates.

File names and line numbers

Xslate reports file names and line numbers, but you can access them via __FILE__ and __LINE__ tokens just like as Perl.

If you want reports files and lines from your functions, Text::Xslate->current_file and Text::Xslate->current_line in callbacks are the same as __FILE__ and __LINE__ in templates respectively.

    sub my_sqrt {
        my($n) = @_;

        if($n < 1) {
            # return a message instead of warnings
            return sprintf "!!! Can't take sqrt of $n at %s line %d !!!",
                Text::Xslate->current_file, Text::Xslate->current_line;
        }
        return sqrt($n);
    }

    my $tx = Text::Xslate->new(
        function => { sqrt => \&my_sqrt },
    );

To dump values

You can use any dumping modules via the function option, but Xslate has a builtin dump filter to dump template values.

    <: $value | dump # Dump $value with Data::Dumper :>
