; .replyrc
[ReadLine]
[Autocomplete::Packages]
=head1 DESCRIPTION
This plugin registers a tab key handler to autocomplete package names in Perl
code.
=cut
sub tab_handler {
my $self = shift;
my ($line) = @_;
# $module_name_rx does not permit trailing ::
my ($before, $package_fragment) = $line =~ /(.*?)(${module_name_rx}:?:?)$/;
return unless $package_fragment;
return if $before =~ /->\s*$/; # method call
return if $before =~ /[\$\@\%\&\*]\s*$/;
my $file_fragment = $package_fragment;
$file_fragment =~ s{::}{/}g;
my $re = qr/^\Q$file_fragment/;
my @results;
for my $inc (keys %INC) {
if ($inc =~ $re) {
$inc =~ s{/}{::}g;
$inc =~ s{\.pm$}{};
push @results, $inc;
}
}
push @results,
grep m/^\Q$package_fragment/,
@{$self->{moar_packages}||=[]};
return @results;
}
# listen for events from the Packages plugin, for its wise wisdom
# can teach us about packages that are not in %INC
sub package {
my $self = shift;
my ($pkg) = @_;
