462
463File::Slurp - Efficient Reading/Writing of Complete Files
464
465=head1 SYNOPSIS
466
467 use File::Slurp;
468
469 my $text = read_file( 'filename' ) ;
470 my @lines = read_file( 'filename' ) ;
471
472 write_file( 'filename', @lines ) ;
473
474 use File::Slurp qw( slurp ) ;
475
476 my $text = slurp( 'filename' ) ;
477
478
479=head1 DESCRIPTION
480
481This module provides subs that allow you to read or write entire files
482with one simple call. They are designed to be simple to use, have
483flexible ways to pass in or get the file contents and to be very
484efficient. There is also a sub to read in all the files in a
485directory other than C<.> and C<..>
486
487These slurp/spew subs work for files, pipes and
488sockets, and stdio, pseudo-files, and DATA.
489
490=head2 B<read_file>
491
492This sub reads in an entire file and returns its contents to the
493caller. In list context it will return a list of lines (using the
494current value of $/ as the separator including support for paragraph
495mode when it is set to ''). In scalar context it returns the entire
496file as a single scalar.
497
498 my $text = read_file( 'filename' ) ;
499 my @lines = read_file( 'filename' ) ;
500
501The first argument to C<read_file> is the filename and the rest of the
502arguments are key/value pairs which are optional and which modify the
503behavior of the call. Other than binmode the options all control how
504the slurped file is returned to the caller.
505
506If the first argument is a file handle reference or I/O object (if ref
507is true), then that handle is slurped in. This mode is supported so
508you slurp handles such as C<DATA>, C<STDIN>. See the test handle.t
509for an example that does C<open( '-|' )> and child process spews data
510to the parant which slurps it in. All of the options that control how
511the data is returned to the caller still work in this case.
512
513NOTE: as of version 9999.06, read_file works correctly on the C<DATA>
514handle. It used to need a sysseek workaround but that is now handled
515when needed by the module itself.
516
517You can optionally request that C<slurp()> is exported to your code. This
518is an alias for read_file and is meant to be forward compatible with
519Perl 6 (which will have slurp() built-in).
520
521The options are:
522
523=head3 binmode
524
525If you set the binmode option, then the file will be slurped in binary
526mode.
527
528 my $bin_data = read_file( $bin_file, binmode => ':raw' ) ;
529
530NOTE: this actually sets the O_BINARY mode flag for sysopen. It
531probably should call binmode and pass its argument to support other
532file modes.
533
534=head3 array_ref
535
536If this boolean option is set, the return value (only in scalar
537context) will be an array reference which contains the lines of the
538slurped file. The following two calls are equivalent:
539
540 my $lines_ref = read_file( $bin_file, array_ref => 1 ) ;
541 my $lines_ref = [ read_file( $bin_file ) ] ;
542
543=head3 scalar_ref
544
545If this boolean option is set, the return value (only in scalar
546context) will be an scalar reference to a string which is the contents
547of the slurped file. This will usually be faster than returning the
548plain scalar.
549
550 my $text_ref = read_file( $bin_file, scalar_ref => 1 ) ;
551
552=head3 buf_ref
553
554You can use this option to pass in a scalar reference and the slurped
555file contents will be stored in the scalar. This can be used in
556conjunction with any of the other options.
557
558 my $text_ref = read_file( $bin_file, buf_ref => \$buffer,
559 array_ref => 1 ) ;
560 my @lines = read_file( $bin_file, buf_ref => \$buffer ) ;
561
562=head3 blk_size
563
564You can use this option to set the block size used when slurping from an already open handle (like \*STDIN). It defaults to 1MB.
565
566 my $text_ref = read_file( $bin_file, blk_size => 10_000_000,
567 array_ref => 1 ) ;
568
569=head3 err_mode
570
571You can use this option to control how read_file behaves when an error
572occurs. This option defaults to 'croak'. You can set it to 'carp' or
573to 'quiet to have no error handling. This code wants to carp and then
574read abother file if it fails.
575
576 my $text_ref = read_file( $file, err_mode => 'carp' ) ;
577 unless ( $text_ref ) {
578
579 # read a different file but croak if not found
580 $text_ref = read_file( $another_file ) ;
581 }
582
583 # process ${$text_ref}
584
585=head2 B<write_file>
586
587This sub writes out an entire file in one call.
588
589 write_file( 'filename', @data ) ;
590
591The first argument to C<write_file> is the filename. The next argument
592is an optional hash reference and it contains key/values that can
593modify the behavior of C<write_file>. The rest of the argument list is
594the data to be written to the file.
595
596 write_file( 'filename', {append => 1 }, @data ) ;
597 write_file( 'filename', {binmode => ':raw' }, $buffer ) ;
598
599As a shortcut if the first data argument is a scalar or array
600reference, it is used as the only data to be written to the file. Any
601following arguments in @_ are ignored. This is a faster way to pass in
602the output to be written to the file and is equivilent to the
603C<buf_ref> option. These following pairs are equivilent but the pass
604by reference call will be faster in most cases (especially with larger
605files).
606
607 write_file( 'filename', \$buffer ) ;
608 write_file( 'filename', $buffer ) ;
609
610 write_file( 'filename', \@lines ) ;
611 write_file( 'filename', @lines ) ;
612
613If the first argument is a file handle reference or I/O object (if ref
614is true), then that handle is slurped in. This mode is supported so
615you spew to handles such as \*STDOUT. See the test handle.t for an
616example that does C<open( '-|' )> and child process spews data to the
617parant which slurps it in. All of the options that control how the
618data is passes into C<write_file> still work in this case.
619
620C<write_file> returns 1 upon successfully writing the file or undef if
621it encountered an error.
622
623The options are:
624
625=head3 binmode
626
627If you set the binmode option, then the file will be written in binary
628mode.
629
630 write_file( $bin_file, {binmode => ':raw'}, @data ) ;
631
632NOTE: this actually sets the O_BINARY mode flag for sysopen. It
633probably should call binmode and pass its argument to support other
634file modes.
635
636=head3 buf_ref
637
638You can use this option to pass in a scalar reference which has the
639data to be written. If this is set then any data arguments (including
640the scalar reference shortcut) in @_ will be ignored. These are
641equivilent:
642
643 write_file( $bin_file, { buf_ref => \$buffer } ) ;
644 write_file( $bin_file, \$buffer ) ;
645 write_file( $bin_file, $buffer ) ;
646
647=head3 atomic
648
649If you set this boolean option, the file will be written to in an
650atomic fashion. A temporary file name is created by appending the pid
651($$) to the file name argument and that file is spewed to. After the
652file is closed it is renamed to the original file name (and rename is
653an atomic operation on most OS's). If the program using this were to
654crash in the middle of this, then the file with the pid suffix could
655be left behind.
656
657=head3 append
658
659If you set this boolean option, the data will be written at the end of
660the current file.
661
662 write_file( $file, {append => 1}, @data ) ;
663
664C<write_file> croaks if it cannot open the file. It returns true if it
665succeeded in writing out the file and undef if there was an
666error. (Yes, I know if it croaks it can't return anything but that is
667for when I add the options to select the error handling mode).
668
669=head3 no_clobber
670
671If you set this boolean option, an existing file will not be overwritten.
672
673 write_file( $file, {no_clobber => 1}, @data ) ;
674
675=head3 err_mode
676
677You can use this option to control how C<write_file> behaves when an
678error occurs. This option defaults to 'croak'. You can set it to
679'carp' or to 'quiet' to have no error handling other than the return
680value. If the first call to C<write_file> fails it will carp and then
681write to another file. If the second call to C<write_file> fails, it
682will croak.
683
684 unless ( write_file( $file, { err_mode => 'carp', \$data ) ;
685
686 # write a different file but croak if not found
687 write_file( $other_file, \$data ) ;
688 }
689
690=head2 overwrite_file
691
692This sub is just a typeglob alias to write_file since write_file
693always overwrites an existing file. This sub is supported for
694backwards compatibility with the original version of this module. See
695write_file for its API and behavior.
696
697=head2 append_file
698
699This sub will write its data to the end of the file. It is a wrapper
700around write_file and it has the same API so see that for the full
701documentation. These calls are equivilent:
702
703 append_file( $file, @data ) ;
704 write_file( $file, {append => 1}, @data ) ;
705
706=head2 read_dir
707
708This sub reads all the file names from directory and returns them to
709the caller but C<.> and C<..> are removed by default.
710
711 my @files = read_dir( '/path/to/dir' ) ;
712
713It croaks if it cannot open the directory.
714
715In a list context C<read_dir> returns a list of the entries in the
716directory. In a scalar context it returns an array reference which has
717the entries.
718
719=head3 keep_dot_dot
720
721If this boolean option is set, C<.> and C<..> are not removed from the
722list of files.
723
724 my @all_files = read_dir( '/path/to/dir', keep_dot_dot => 1 ) ;

735=head2 BUGS
736
737If run under Perl 5.004, slurping from the DATA handle will fail as
738that requires B.pm which didn't get into core until 5.005.
