=head1 NAME

File::ShareDir::Install - Install shared files

=head1 VERSION

version 0.14

=head1 SYNOPSIS

use ExtUtils::MakeMaker;
    use File::ShareDir::Install;

install_share 'share';
    install_share dist => 'dist-share';
    install_share module => 'My::Module' => 'other-share';

WriteMakefile( ... );       # As you normally would

package MY;
    use File::ShareDir::Install qw(postamble);

=head1 DESCRIPTION

File::ShareDir::Install allows you to install read-only data files from a
distribution. It is a companion module to L<File::ShareDir>, which
allows you to locate these files after installation.

It is a port of L<Module::Install::Share> to L<ExtUtils::MakeMaker> with the
improvement of only installing the files you want; C<.svn>, C<.git> and other
source-control junk will be ignored.

Please note that this module installs read-only data files; empty
directories will be ignored.

=head1 EXPORT

=head2 install_share

install_share $dir;
    install_share dist => $dir;
    install_share module => $module, $dir;

Causes all the files in C<$dir> and its sub-directories to be installed
into a per-dist or per-module share directory.  Must be called before
C<WriteMakefile>.

The first 2 forms are equivalent; the files are installed in a per-distribution
directory.  For example C</usr/lib/perl5/site_perl/auto/share/dist/My-Dist>.  The
name of that directory can be recovered with L<File::ShareDir/dist_dir>.

The last form installs files in a per-module directory.  For example
C</usr/lib/perl5/site_perl/auto/share/module/My-Dist-Package>.  The name of that
directory can be recovered with L<File::ShareDir/module_dir>.

The parameter C<$dir> may be an array of directories.

The files will be installed when you run C<make install>.  However, the list
of files to install is generated when Makefile.PL is run.

Note that if you make multiple calls to C<install_share> on different
directories that contain the same filenames, the last of these calls takes
precedence.  In other words, if you do:

install_share 'share1';
    install_share 'share2';

And both C<share1> and C<share2> contain a file called C<info.txt>, the file
C<share2/info.txt> will be installed into your C<dist_dir()>.

=head2 delete_share

delete_share $list;
    delete_share dist => $list;
    delete_share module => $module, $list;

Remove previously installed files or directories.

Unlike L</install_share>, the last parameter is a list of files or
directories that were previously installed.  These files and directories will
be deleted when you run C<make install>.

The parameter C<$list> may be an array of files or directories.

Deletion happens in-order along with installation.  This means that you may
delete all previously installed files by putting the following at the top of
your Makefile.PL.

delete_share '.';

You can also selectively remove some files from installation.

install_share 'some-dir';
    if( ... ) {
        delete_share 'not-this-file.rc';
    }

=head2 postamble

This function must be exported into the MY package.  You will normally do this
with the following.

package MY;
    use File::ShareDir::Install qw( postamble );

If you need to overload postamble, use the following.

package MY;
    use File::ShareDir::Install;

sub postamble {
        my $self = shift;
        my @ret = File::ShareDir::Install::postamble( $self );
        # ... add more things to @ret;
        return join "\n", @ret;
    }

=head1 CONFIGURATION

Two variables control the handling of dot-files and dot-directories.

A dot-file has a filename that starts with a period (.).  For example
C<.htaccess>. A dot-directory is a directory that starts with a
period (.).  For example C<.config/>.  Not all filesystems support the use
of dot-files.

=head2 $INCLUDE_DOTFILES

If set to a true value, dot-files will be copied.  Default is false.

=head2 $INCLUDE_DOTDIRS

If set to a true value, the files inside dot-directories will be copied.
Known version control directories are still ignored.  Default is false.

=head2 Note

These variables only influence subsequent calls to C<install_share()>.  This allows
you to control the behaviour for each directory.

For example:

$INCLUDE_DOTDIRS = 1;
    install_share 'share1';
    $INCLUDE_DOTFILES = 1;
    $INCLUDE_DOTDIRS = 0;
    install_share 'share2';

The directory C<share1> will have files in its dot-directories installed,
but not dot-files.  The directory C<share2> will have files in its dot-files
installed, but dot-directories will be ignored.
