79 FancyPrompt helps you write your own prompts. The default fancy prompt resembles
80 C<irb>'s default prompt. The default C<fancy_prompt> looks like this:
82 re.pl(main):001:0> 2 + 2
85 C<re.pl> is a constant. C<main> is the current package. The first number is how
86 many lines have been read so far. The second number (only if you have a
87 C<MultiLine> plugin) is how deep you are; intuitively, your indent level. This
88 default can be implemented with:
90 $_REPL->fancy_prompt(sub {
92 sprintf 're.pl(%s):%03d%s> ',
93 $self->can('current_package') ? $self->current_package : 'main',
95 $self->can('line_depth') ? ':' . $self->line_depth : '';
98 C<current_package> is provided by L<Devel::REPL::Plugin::Packages> (which
99 tracks the current package). C<line_depth> is provided by a C<MultiLine> plugin
100 (probably C<MultiLine::PPI>).
102 You may also set a C<fancy_continuation_prompt>. The default is very similar to
103 C<fancy_prompt>'s default (except C<*> instead of C<< > >>).
