NAME ^

File::Find::utf8 - Fully UTF-8 aware File::Find

VERSION ^

version 0.013

SYNOPSIS ^

    # Use the utf-8 versions of find and finddepth
    use File::Find::utf8;
    find(\&wanted, @directories_to_search);

    # Revert back to non-utf-8 versions
    no File::Find::utf8;
    finddepth(\&wanted, @directories_to_search);

    # Export only the find function
    use File::Find::utf8 qw(find);
    find(\&wanted, @directories_to_search);

    # Export no functions
    use File::Find::utf8 qw(:none); # NOT "use File::Find::utf8 qw();"!
    File::Find::find(\&wanted, @directories_to_search);

DESCRIPTION ^

While the original File::Find functions are capable of handling UTF-8 quite well, they expect and return all data as bytes, not as characters.

This module replaces the File::Find functions with fully UTF-8 aware versions, both expecting and returning characters.

Note: Replacement of functions is not done on DOS, Windows, and OS/2 as these systems do not have full UTF-8 file system support.

Behaviour

The module behaves as a pragma so you can use both use File::Find::utf8 and no File::Find::utf8 to turn utf-8 support on or off.

By default, both find() and finddepth() are exported (as with the original File::Find), if you want to prevent this, use use File::Find::utf8 qw(:none). (As all the magic happens in the module's import function, you can not simply use use File::Find::utf8 qw())

File::Find warning levels are properly propagated. Note though that for propagation of fatal File::Find warnings, Perl 5.12 or higher is required (or the appropriate version of warnings).

ATTRIBUTES ^

$File::Find::utf8::SPECIALVARS

By default File::Find::utf8 only decodes the normal File::Find variables $_, $File::Find::name, $File::Find::dir, and (when follow or follow_fast is in effect) $File::Find::fullname for use in the preprocess, wanted, and postporcess functions.

If for any reason (e.g., compatibility with find.pl or find2perl) you also need the special variables $File::Find::topdir, $File::Find::topdev, $File::Find::topino, $File::Find::topmode, and $File::Find::topnlink to be decoded, specify local $File::Find::utf8::COMPATILBILITY = 1; in your code. The extra decoding that needs to happen will impact performance though, so use only when absolutely necessary.

$File::Find::utf8::UTF8_CHECK

By default File::Find::utf8 marks decoding errors as fatal (default value for this setting is Encode::FB_CROAK). If you want, you can change this by setting File::Find::utf8::UTF8_CHECK. The value Encode::FB_WARN reports the encoding errors as warnings, and Encode::FB_DEFAULT will completely ignore them. Please see Encode for details. Note: Encode::LEAVE_SRC is always enforced.

BUGS ^

Please report any bugs or feature requests on the bugtracker website.

When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.

COMPATIBILITY ^

The filesystems of Dos, Windows, and OS/2 do not (fully) support UTF-8. The File::Find function will therefore not be replaced on these systems.
