Distributing a perl script
Hi all,
I'm new to the world of Perl so may have gone about this in the wrong way (my background is mainly Java and Bash).
I have a Perl script (gallery.pl) which takes in various arguments (the only mandatory arguments is a directory full of images) and creates an HTML, standards compliant gallery. Seeing how images might be too big, I use the Image::Magick module to do any resizing that is necessary.
If I want to pass this script to a technically minded user to use then I'd just email the script or put it on my site for them to download and then they can sort out any modules they need to install.
However, what about non-technically minded users? How can I distribute my script in such a way that the end user doesn't have to care about missing dependancies?
I've thought about an installation script to install the main script under /opt/local/bin, could I use this installation script to install missing modules? If so, how might I do this?
I've tried looking at things like Module::AutoInstall and ExtUtils::MakeMaker but my interpretation is that these are only for modules, not for scripts.
Sorry to sound so dim about it all, but as I said, it's all rather new to me!
Many thanks,
Ben

NAME
Catalyst::Manual::Deployment::SharedHosting - Deploying Catalyst on Shared Hosting
Catalyst on shared hosting
So, you want to put your Catalyst application out there for the whole world to see, but you don't want to break the bank. There is an
answer - if you can get shared hosting with FastCGI and a shell, you can install your Catalyst app in a local directory on your shared
host. First, run
perl -MCPAN -e shell
and go through the standard CPAN configuration process. Then exit without installing anything. Next, download the latest local::lib package
and follow its 'bootstrap' instructions to get it installed and the local configuration added to your "~/.bashrc".
Now log out, then back in again (or run ". .bashrc" if you prefer).
Now you can install the modules you need using CPAN as normal; they will be installed into your local directory, and Perl will pick them
up. Finally, change into the root directory of your virtual host, and symlink your application's script directory:
cd path/to/mydomain.com
ln -s ~/lib/MyApp/script script
And add the following lines to your .htaccess file (assuming the server is setup to handle .pl as fcgi - you may need to rename the script
to myapp_fastcgi.fcgi and/or use a SetHandler directive):
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/?script/myapp_fastcgi.pl
RewriteRule ^(.*)$ script/myapp_fastcgi.pl/$1 [PT,L]
Now "http://mydomain.com/" should now Just Work. Congratulations, now you can tell your friends about your new website.
