Text::CSV::Encoded::Coder::EncodeGuess(3pm)		User Contributed Perl Documentation	       Text::CSV::Encoded::Coder::EncodeGuess(3pm)

NAME

       Text::CSV::Encoded::Coder::EncodeGuess - Text::CSV::Encoded coder class using Encode::Guess

SYNOPSIS

	   use Text::CSV::Encoded  coder_class => 'Text::CSV::Encoded::Coder::EncodeGuess';
	   use Spreadsheet::ParseExcel;

	   my $csv = Text::CSV::Encoded->new();

	   $csv->encoding( ['ucs2', 'ascii'] ); # guessing ucs2 or ascii?
	   $csv->encoding_to_combine('shiftjis');

	   my $excel = Spreadsheet::ParseExcel::Workbook->Parse( $file );
	   my $sheet = $excel->{Worksheet}->[0];

	   for my $row ( $sheet->{MinRow} .. $sheet->{MaxRow} ) {
	       my @fields;

	       for my $col ( $sheet->{MinCol} ..  $sheet->{MaxCol} ) {
		   my $cell = $sheet->{Cells}[$row][$col];
		   push @fields, $cell->{Val};
	       }

	       $csv->combine( @fields ) or die;
	       print $csv->string, "
";
	   }

DESCRIPTION

       This module is inherited from Text::CSV::Encoded::Coder::Encode.

USE

       Except for 2 attributes, same as Text::CSV::Encoded::Coder::Encode.

   encoding_in
	   $csv = $csv->encoding_in( $encoding_list_ref );

       The accessor to an encoding for pre-parsing CSV strings.  If no encoding is given, returns current $encoding, otherwise the object itself.

	   $encoding_list_ref = $csv->encoding_in()

       When you pass a list reference, it might guess the encoding from the given list.

	   $csv->encoding_in( ['shiftjis', 'euc-jp', 'iso-20022-jp'] );

       If it cannot guess the encoding, the first encoding of the list is used.

   encoding
	   $csv = $csv->encoding( $encoding_list_ref );
	   $encoding_list_ref = $csv->encoding();

       You can pass a list reference to this attribute only:

	 * For list data consumed by combine().
	 * For list reference returned by getline().

       In other word, in "combine" and "print", it might guess an encoding for the passing list data.  If it cannot guess the encoding, the first
       encoding of the list is used.
