77 | =head1 DESCRIPTION |
78 | |
79 | This plugin provides a C<concise> command that uses L<B::Concise> to dump |
80 | optrees of expressions. |
81 | |
82 | The code is not actually executed, which means that when used with |
c5bf3ed2 |
83 | L<Deve::REPL::Plugin::OutputCache> there is no new value in C<_>. |
320b3ad5 |
84 | |
85 | The command takes the same options as L<B::Concise/compile>, e.g. C<-basic> or |
86 | C<-exec> to determine the dump order, C<-debug>, C<-concise> and C<-terse> to |
87 | determine the formatting, etc. |
