Re^3: Using Tab Completion on Windows in cmd.exe

[Stamm]

I'm using Windows 7. I think you must have Term::ReadLine::Perl installed. Otherwise, Term::ReadLine::Stub will be used, which doesn't do word completion.

Yeah, I got that, I have it

$ perl -MTerm::ReadLine -MTerm::ReadLine::Perl -d:Modlist -e 1
Carp                   1.23
Exporter               5.65
Term::ReadLine         1.07
Term::ReadLine::Perl 1.0303
warnings               1.12

perl -d:Modlist -e "  use Term::Complete; $|=1; warn $input = Complete( q[ type or tab  ] , [ qw[ ro sham bo foo bar baz ] ] ); " doesn't work for me

update: of course, it doesn't use Term::Readline, duh ...

So, what are you using, and how (short example please)?

[Stamm]

You're right, it doesn't work with Term::Complete. I thought I had tested it. As you said, it doesn't even use Term::ReadLine.

It works with Term::Shell. Here with the pod example slightly modified:


package MyShell;

$ENV{TERM} = '';

use base qw(Term::Shell);

sub run_command1  { print "command 1!\n"; }
sub smry_command1 { "what does command1 do?" }
sub help_command1 { "Help on 'command1', whatever that may be..." }

sub run_command2 { print "command 2!\n"; }


package main;

my $shell = MyShell->new;
$shell->cmdloop;


Or directly with Term::ReadLine:


use Term::ReadLine;
  
$ENV{TERM} = '';
  
my $term = Term::ReadLine->new('Tab Completion');
my $prompt = ">>> ";

&readline::rl_basic_commands( qw(set quit type test run exit) );
  
while ( defined ( $_ = $term->readline($prompt) ) )
{
    exit if /exit/ or /quit/;
    print $_, "\n";
}

Thank you, that seems usable

For me, if i start typing something, and hit tab, it gets completed

This i expected

But if I only type tab, nothing happens until I hit tab again, at which point a newline is printed, then the available tab choices and a newline, then the prompt again

This i didn't expect, I kinda expected it to cycle through list of completions, like cmd.exe does for filenames, like my demo from earlier, with shift+tab going in reverse (as is common, but which my version doesn't do)

At least it usable
