# NAME
Template::Reverse - A template generator getting different parts between pair of text
# VERSION
version 0.202
# SYNOPSIS
use Template::Reverse;
my $rev = Template::Reverse->new();
my $parts = $rev->detect($arr_ref1, $arr_ref2); # returns [ Template::Reverser::Part, ... ]
use Template::Reverse::Converter::TT2;
my $converter = Template::Reverse::Converter::TT2->new();
my @templates = $converter->Convert($parts);
more
# try this!!
use Template::Reverse;
use Data::Dumper;
my $rev = Template::Reverse->new;
# generating patterns automatically!!
my $str1 = ['I',' ','am',' ', 'perl',' ','and',' ','smart']; # White spaces should be explained explicity.
my $str2 = ['I',' ','am',' ', 'khs' ,' ','and',' ','a',' ','perlmania']; # Use Parse::Lex or Parse::Token::Lite to make it easy.
my $parts = $rev->detect($str1, $str2);
my $str3 = "I am king of the world and a richest man";
# extract with TT2
use Template::Reverse::Converter::TT2;
my $tt2 = Template::Reverse::Converter::TT2->new;
my $templates = $tt2->Convert($parts); # equals to ['I am [% value %] and ',' and [% value %]']
use Template::Extract;
my $ext = Template::Extract->new;
my $value = $ext->extract($templates->[0], $str3);
print Dumper($value); # output : {'value'=>'king of the world'}
my $value = $ext->extract($templates->[1], $str3);
print Dumper($value); # output : {'value'=>'a richest man'}
# extract with Regexp
my $regexp_conv = Template::Reverse::Converter::Regexp->new;
my $regexp_list = $regexp_conv->Convert($parts);
my $str3 = "I am king of the world and a richest man";
# extract!!
foreach my $regexp (@{$regexp_list}){
if( $str3 =~ /$regexp/ ){
print $1."\n";
}
}
# When you need to get regexp as string.
use re regexp_pattern;
my($pat,$flag) = regexp_pattern( $regexp_list->[0] );
print $pat; # Regexp generates regexps without flags. So you do not need to use $flag.
# DESCRIPTION
Template::Reverse detects different parts between pair of similar text as merged texts from same template.
And it can makes an output marked differences, encodes to TT2 format for being use by Template::Extract module.
# CI
# FUNCTIONS
### new(OPTION\_HASH\_REF)
#### sidelen=>$max\_length\_of\_each\_side
sidelen is a short of "side character's each max length".
the default value is 10. Setting 0 means full-length.
If you set it as 3, you get max 3 length pre-text and post-text array each part.
This is needed for more faster performance.
### BOF, EOF
Template::Reverse exports BOF(Begin of file) and EOF(End of file).
These are needed for more explicit implementation.
And you can see them return parts
### detect($arr\_ref1, $arr\_ref2)
Get an array-ref of [Template::Reverse::Part](https://metacpan.org/pod/Template::Reverse::Part) from two array-refs which contains text or object implements as\_string() method.
A [Template::Reverse::Part](https://metacpan.org/pod/Template::Reverse::Part) class means an one changable token.
It returns like below.
$rev->detect([qw(A b C)], [qw(A d C)]);
# List is converted as below
#
# qw(A b C) -> (BOF, qw(A b C), EOF)
#
# [ { [BOF, 'A'],['C', EOF] } ] <- Please focus at data, not expression.
# : :........: :..,,,,,.: :
# : pre post :
# :.......................:
# Part #1
#
$rev->detect([qw(A b C d E)],[qw(A f C g E)]);
#
# [ { [BOF, 'A'], ['C'] }, { ['C'], ['E', EOF] } ]
# : :........: :...: : : :...: :........: :
# : pre post : : pre post :
# :...................: :...................:
# Part #1 Part #2
#
$rev->detect([qw(A1 A2 B C1 C2 D E1 E2)],[qw(A1 A2 D C1 C2 F E1 E2)]);
#
# [ { [BOF,'A1','A2'],['C2','C2'] }, { ['C1','C2'], ['E2','E2',EOF] } ]
#
my $str1 = [qw"I am perl and smart"];
my $str2 = [qw"I am KHS and a perlmania"];
my $parts = $rev->detect($str1, $str2);
#
# [ { [BOF,'I','am'], ['and'] } , { ['and'],[EOF] } ]
# : :............: :.....: : : :
# : pre post : : :
# :.........................: :...............:
# Part #1 Part #2
#
# You can get same result for object arrays.
my $objs1 = [$obj1, $obj2, $obj3];
my $objs2 = [$obj1, $obj3];
#
# [ { [ BOF,$obj1 ], [ $obj3, EOF ] } ]
# : :...........: :............: :
# : pre post :
# :...............................:
# Part #1
Returned arrayRef is list of detected changing parts.
Actually, the returned value is like below.
[
{pre=>[BOF, ...], post=>[...]},
...
{pre=>[...], post=>[..., EOF]},
]
You can get a changed token if you find just 'pre' and 'post' parts on splited target.
