NAME¶

Devel::REPL::Plugin::FancyPrompt - facilitate user-defined prompts

SYNOPSIS¶

    #!/usr/bin/perl 
    use lib './lib';
    use Devel::REPL;
    my $repl = Devel::REPL->new;
    $repl->load_plugin('MultiLine::PPI'); # for indent depth
    $repl->load_plugin('Packages');       # for current package
    $repl->load_plugin('FancyPrompt');
    $repl->run;

DESCRIPTION¶

FancyPrompt helps you write your own prompts. The default fancy prompt resembles "irb"'s default prompt. The default "fancy_prompt" looks like this:

    re.pl(main):001:0> 2 + 2
    4

"re.pl" is a constant. "main" is the current package. The first number is how many lines have been read so far. The second number (only if you have a "MultiLine" plugin) is how deep you are; intuitively, your indent level. This default can be implemented with:

    $_REPL->fancy_prompt(sub {
      my $self = shift;
      sprintf 're.pl(%s):%03d%s> ',
              $self->can('current_package') ? $self->current_package : 'main',
              $self->lines_read,
              $self->can('line_depth') ? ':' . $self->line_depth : '';
    });

"current_package" is provided by Devel::REPL::Plugin::Packages (which tracks the current package). "line_depth" is provided by a "MultiLine" plugin (probably "MultiLine::PPI"). You may also set a "fancy_continuation_prompt". The default is very similar to "fancy_prompt"'s default (except "*" instead of ">").
