NAME

       Regexp::RegGrp - Groups a regular expressions collection

VERSION

       Version 1.002

DESCRIPTION

       Groups regular expressions to one regular expression

SYNOPSIS

	   use Regexp::RegGrp;

	   my $reggrp = Regexp::RegGrp->new(
	       {
		   reggrp	   => [
		       {
			   regexp => '%name%',
			   replacement => 'John Doe',
			   modifier    => $modifier
		       },
		       {
			   regexp => '%company%',
			   replacement => 'ACME',
			   modifier    => $modifier
		       }
		   ],
		   restore_pattern => $restore_pattern
	       }
	   );

	   $reggrp->exec( $scalar );

       To return a scalar without changing the input simply use (e.g. example 2):

	   my $ret = $reggrp->exec( $scalar );

       The first argument must be a hashref. The keys are:

       reggrp (required)
	   Arrayref of hashrefs. The keys of each hashref are:

	   regexp (required)
		   A regular expression

	   replacement (optional)
		   Scalar or sub.

		   A replacement for the regular expression match. If not set, nothing will be replaced except "store" is set.	In this case the
		   match is replaced by something like sprintf("x01%dx01", $idx) where $idx is the index of the stored element in the store_data
		   arrayref. If "store" is set the default is:

		       sub {
			   return sprintf( "x01%dx01", $_[0]->{store_index} );
		       }

		   If a custom restore_pattern is passed to to constructor you MUST also define a replacement. Otherwise it is undefined.

		   If you define a subroutine as replacement an hashref is passed to this subroutine. This hashref has four keys:

		   match       Scalar. The match of the regular expression.

		   submatches  Arrayref of submatches.

		   store_index The next index. You need this if you want to create a placeholder and store the replacement in the
			       $self->{store_data} arrayref.

		   opts        Hashref of custom options.

	   modifier (optional)
		   Scalar. The default is 'sm'.

	   store (optional)
		   Scalar or sub. If you define a subroutine an hashref is passed to this subroutine. This hashref has three keys:

		   match       Scalar. The match of the regular expression.

		   submatches  Arrayref of submatches.

		   opts        Hashref of custom options.

		   A replacement for the regular expression match. It will not replace the match directly. The replacement will be stored in the
		   $self->{store_data} arrayref. The placeholders in the text can easily be rereplaced with the restore_stored method later.

       restore_pattern (optional)
	   Scalar or Regexp object. The default restore pattern is

	       qr~x01(d+)x01~

	   This means, if you use the restore_stored method it is looking for x010x01, x011x01, ... and replaces the matches with
	   $self->{store_data}->[0], $self->{store_data}->[1], ...

EXAMPLES

       Example 1
	   Common usage.

	       #!/usr/bin/perl

	       use strict;
	       use warnings;

	       use Regexp::RegGrp;

	       my $reggrp = Regexp::RegGrp->new(
		   {
		       reggrp	       => [
			   {
			       regexp => '%name%',
			       replacement => 'John Doe'
			   },
			   {
			       regexp => '%company%',
			       replacement => 'ACME'
			   }
		       ]
		   }
	       );

	       open( INFILE, 'unprocessed.txt' );
	       open( OUTFILE, '>processed.txt' );

	       my $txt = join( '', <INFILE> );

	       $reggrp->exec( $txt );

	       print OUTFILE $txt;
	       close(INFILE);
	       close(OUTFILE);

       Example 2
	   A scalar is requested by the context. The input will remain unchanged.

	       #!/usr/bin/perl

	       use strict;
	       use warnings;

	       use Regexp::RegGrp;

	       my $reggrp = Regexp::RegGrp->new(
		   {
		       reggrp	       => [
			   {
			       regexp => '%name%',
			       replacement => 'John Doe'
			   },
			   {
			       regexp => '%company%',
			       replacement => 'ACME'
			   }
		       ]
		   }
	       );

	       open( INFILE, 'unprocessed.txt' );
	       open( OUTFILE, '>processed.txt' );

	       my $unprocessed = join( '', <INFILE> );

	       my $processed = $reggrp->exec( $unprocessed );

	       print OUTFILE $processed;
	       close(INFILE);
	       close(OUTFILE);
