=head1 NAME

Devel::REPL::Plugin::Nopaste - #nopaste to upload session's input and output

=head1 VERSION

version 1.003029

=head1 COMMANDS

This module provides these commands to your Devel::REPL shell:

=head2 #nopaste

The C<#nopaste> sends a transcript of your session to a nopaste
site.

=head2 #pastetitle

The C<#pastetitle> command allows you to set the title of the paste on
the nopaste site. For example:

C<#pastetitle example of some code>

defaults to C<'Devel::REPL session'>.

=head1 CONFIGURATION

=head2 nopaste_format

The format sent to the nopaste server can be adjusted with the
C<nopaste_format> option. By default, the output of each perl
statement is commented out, and the perl statements themselves are
not. This can be reversed by setting the C<nopaste_format> attribute
to C<comment_code> like this in your re.pl file:

C<< $_REPL->nopaste_format( 'comment_code' ); >>

The default of commenting out the output would be set like this:

C<< $_REPL->nopaste_format( 'comment_output' ); >>

These options can be set during a L<Devel::REPL> session, but only affect
the future parts of the session, not the past parts.
