Question

Supposed I have a file with Perl-code: does somebody know, if there is a module which could find the closing “}” of a certain subroutine in that file.
For example:

#!/usr/bin/env perl
use warnings;
use 5.012;

routine_one( '{°^°}' );

routine_two();

sub routine_one {
    my $arg = shift;
    if ( $arg =~ /}\z/ ) {
    say "Hello my }";
    }
}

sub routine_two {
    say '...' for 0 .. 10
}

The module should be able to remove the whole routine_one or it should can tell me the line-number of the closing “}” from that routine.

You want to use PPI if you are going to be parsing Perl code.
