Vasek has asked for the wisdom of the Perl Monks concerning the following question:

Dear Monks,

Could you help me:
I wanna put some default text to STDIN which is "editable". There should be something like this:

>$\HEAD\some_dir_from_a_scalar_value

where the red text is just a prompt, and the rest is the default input text, which one should be editable by the user

Thanks: Vasek

    In case you have Term::ReadLine::Gnu installed, you can do: 

    #!/usr/bin/perl

use Term::ReadLine;

my $term = new Term::ReadLine 'Demo';

my $prompt = '$\\HEAD\\';
my $dir    = "foo/bar";  # user-editable default input

my $user_input = $term->readline($prompt, $dir);
print "user_input: $user_input\n";

    (BTW, what you refer to as STDIN is usually called the terminal/console's prompt, strictly speaking...)
