in reply to Using Tab Completion on Windows in cmd.exe

Can't really help you about tab completion. You could read in the keypresses chararcter by character and write your own parser. But i guess this should already be a solved problem.

A workaround would be to use Term::Readline. You could - for example - prepolulate the history. Something like this:

#!/usr/bin/perl use strict; use warnings; use Term::ReadLine; my $term = Term::ReadLine->new('Tabtest'); my $prompt = "Test your tabs, guv: "; if ($^O eq "MSWin32" || $^O eq "dos") { my $INPUT; open($INPUT, "<con") and $term->newTTY($INPUT, $term->OUT); } foreach my $command (qw[print hello echo foo bar baz]) { $term->addhistory($command); } while(defined(my $line = $term->readline($prompt))) { chomp $line; exit if($line eq "exit"); print "I don't know how to '$line'\n"; $term->addhistory($line); }

Not quite what you wanted, i know, but i'm also fresh out of ideas.

Don't use '#ff0000':
use Acme::AutoColor; my $redcolor = RED();
All colors subject to change without notice.

    Thanks for your answer. And yes, I thought it would have been solved too.

    As for your code, I'm not sure I understand. Command history already works.

    Maybe I should have Term::ReadLine::Gnu. But I can't install it. It says libtermcap.a or libcurses.a is missing. Anybody know what I should be doing?

      Install libetrmcap or libcurses, obviously :)

      Or try Term::ReadLine::Perl

        I don't know how to install those libraries. It's not Perl and I can only find resources for Unix. :-(

        And tab completion doesn't work with Term::ReadLine::Perl either.

        It seemed a perfectly simple and reasonable luxury to have for a command-line program...
