App::Nopaste(3pm)					User Contributed Perl Documentation					 App::Nopaste(3pm)

NAME
App::Nopaste - easy access to any pastebin SYNOPSIS
use App::Nopaste 'nopaste'; my $url = nopaste(q{ perl -wle 'print "Prime" if (1 x shift) !~ /^1?$|^(11+?)1+$/' [number] }); # or on the command line: nopaste test.pl => http://pastebin.com/fcba51f DESCRIPTION
Pastebins (also known as nopaste sites) let you post text, usually code, for public viewing. They're used a lot in IRC channels to show code that would normally be too long to give directly in the channel (hence the name nopaste). Each pastebin is slightly different. When one pastebin goes down (I'm looking at you, <http://paste.husk.org>), then you have to find a new one. And if you usually use a script to publish text, then it's too much hassle. This module aims to smooth out the differences between pastebins, and provides redundancy: if one site doesn't work, it just tries a different one. It's also modular: you only need to put on CPAN a App::Nopaste::Service::Foo module and anyone can begin using it. INTERFACE
CLI See the documentation in App::Nopaste::Command. "nopaste" use App::Nopaste 'nopaste'; my $url = nopaste( text => "Full text to paste (the only mandatory argument)", desc => "A short description of the paste", nick => "Your nickname", lang => "perl", chan => "#moose", private => 1, # default: 0 # this is the default, but maybe you want to do something different error_handler => sub { my ($error, $service) = @_; warn "$service: $error"; }, warn_handler => sub { my ($warning, $service) = @_; warn "$service: $warning"; }, # you may specify the services to use - but you don't have to services => ["Shadowcat", "Gist"], ); print $url if $url; The "nopaste" function will return the URL of the paste on success, or "undef" on failure. For each failure, the "error_handler" argument is invoked with the error message and the service that issued it. For each warning, the "warn_handler" argument is invoked with the warning message and the service that issued it. SEE ALSO
