VERSION

version 0.007

SYNOPSIS

    use Template::Reverse;
    my $rev = Template::Reverse->new({
            spacers=>['Template::Reverse::Spacer::Number'],         # put spaces around Numbers. [OPTIONAL]
            splitter=>'Template::Reverse::Splitter::Whitespace',    # and splitting text by white spaces. [DEFAULT]
    });

    my $parts = $rev->detect($output1, $output2); # returns [ [[PRE],[POST]], ... ]

    use Template::Reverse::Converter::TT2;
    my @templates = Template::Reverse::TT2Converter::Convert($parts); # named 'value1','value2',...

    # try this!!
    use Template::Reverse;
    use Template::Reverse::Converter::TT2;
    use Data::Dumper;

    my $rev = Template::Reverse->new;

    # generating patterns automatically!!
    my $str1 = "I am perl and smart";
    my $str2 = "I am khs and a perlmania";
    my $parts = $rev->detect($str1, $str2);

    my $tt2 = Template::Reverse::Converter::TT2->new;
    my $temps = $tt2->Convert($parts); # equals ['I am [% value %] and','and [% value %]']


    # spacing text for normalization.
    my $str3 = "I am king of the world and a richest man";
    my $str3spaced = $rev->space($str3);

    # extract!!
    use Template::Extract;
    my $ext = Template::Extract->new;
    my $value = $ext->extract($temps->[0], $str3spaced);
    print Dumper($value); # output : {'value'=>'king of the world'}

    my $value = $ext->extract($temps->[1], $str3spaced);
    print Dumper($value); # output : {'value'=>'a richest man'}

DESCRIPTION

Template::Reverse detects different parts between pair of similar text as merged texts from same template. And it can makes an output marked differences, encodes to TT2 format for being use by Template::Extract module.

detect($text1, $text2)

Get changable part list from two texts. It returns like below

    $rev->detect('A b C','A d C');
    #
    # [ [ ['A'],['C'] ] ]
    #   : :...: :...: :     
    #   :  pre  post  :
    #   :.............:  
    #       part 1
    #

    $rev->detect('A b C d E','A f C g E');
    #
    # [ [ ['A'], ['C'] ], [ ['C'], ['E'] ] ]
    #   : :...:  :...: :  : :...:  :...: :
    #   :  pre   post  :  :  pre   post  :
    #   :..............:  :..............:
    #        part 1            part 2
    #

    $rev->detect('A1 A2 B C1 C2 D E1 E2','A1 A2 D C1 C2 F E1 E2');
    #
    # [ [ ['A1','A2'],['C2','C2'] ], [ ['C1','C2'], ['E2','E2'] ] ]
    #

    my $str1 = "I am perl and smart";
    my $str2 = "I am KHS and a perlmania";
    my $parts = $rev->detect($str1, $str2);
    #
    # [ [ ['I','am'], ['and'] ] , [ ['and'],[] ] ]
    #   : :........:  :.....: :   :            :
    #   :    pre       post   :   :            :
    #   :.....................:   :............:
    #           part 1                part 2
    #

Returned arrayRef is list of changable parts.

    1. At first, $text1 and $text2 is normalized by Spacers.
    2. 'pre texts' and 'post texts' are splited by Splitter. In this case, by Whitespace.
    3. You can get a changing value, just finding 'pre' and 'post' in a normalized text.

space($text)

It returns a normalized text same as in detect(). Text are processed by Spacers in order. Finding parts in texts, you must use this function with the texts.
