Devel::REPL::Plugin::FancyPrompt - facilitate user-defined prompts
version 1.003026
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;
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 >).
