use Term::Cap. use the POSIX module to probe certain features of the terminal.

#!/usr/local/bin/perl use POSIX; use Term::Cap; # General terminal line I/O my $termios = new POSIX::Termios; $termios->getattr; # Extract the entry of the terminal type my $term = Term::Cap->Tgetent( { OSPEED => $termios->getospeed } ); # clear $term->Tputs('cl', 1, STDOUT);

Shell out and ask the OS to do it:

system $^O eq 'MSWin32' ? 'cls' : 'clear';

    [Corion]: ambrus: Yeah, I read that, but it's somewhat vague as in what I really have to implement, and where/how my "other" mainloop should/needs to call AnyEvent
    [Corion]: (or maybe I just work better from existing code that I munge until it works and I understand it rather than a short abstract text like "implement everything that's needed" ;) )
    [ambrus]: Corion: I think in this case you can get away with only a stub for idle, one that always dies when you create it, because AnyEvent::HTTP doesn't use it, not even indirectly through AnyEvent::Handle or AnyEvent::Socket or AnyEvent::DNS.
    [Corion]: The "and I understand it" part is optional.
    [Corion]: ambrus: Yes but I also need to implement the file / IO watcher, because Prima has that (in Prima::File), and I need to supply the appropriate thing to make push_write etc. work with Prima
