File::ShareDir::Install(3)

NAME
File::ShareDir::Install - Install shared files

VERSION
version 0.11

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);

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

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

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

EXPORT

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

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

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

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

The parameter $dir may be an array of directories.

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

Note that if you make multiple calls to "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 "share1" and "share2" contain a file called "info.txt", the file "share2/info.txt" will be installed into your "dist_dir()".

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

Remove previously installed files or directories.

Unlike "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 "make install".

The parameter $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';
    }

  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;
    }

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 ".htaccess". A dot-directory is a directory that starts with a period (.). For example ".config/". Not all filesystems support the use of dot-files.

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

  $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.

  Note
These variables only influence subsequent calls to "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 "share1" will have files in its dot-directories installed, but not dot-files. The directory "share2" will have files in its dot-files installed, but dot-directories will be ignored.
