fdesar has asked for the wisdom of the Perl Monks concerning the following question:

Hi, Monks,

I seek your wisdom to find a solution to a simple problem I have.

I wrote a Inkscape module in Perl and just finished writing its user-guide for it in PDF format.

This module works either on Windows, MacOS and Linux.

My problem is to find a way to display this PDF file from within my Perl module, using either the default PDF viewer for the OS or its default Internet browser (which certainly knows how to display those files). It seems to me the only way to achieve that is by using the shell but I wonder how to do write command files for such result on each of those three OSes (I perfectly know on which of them I am running).

Any suggestions are welcome.

Many thanks

F.

    This is what I used for URLs in PM::CB::GUI: 
    sub browse {
    my ($url) = @_;
    my $action = {
        MSWin32 => sub { system 1, qq{start "$url" /b "$url"} },
        darwin  => sub { system qq{open "$url" &} },
    }->{$^O}    || sub { system qq{xdg-open "$url" &} };
    $action->();
}

      Thanks a lot: I'll try that!
