Cursors or something

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

Hi,

Shell programming, like in dos or unix/linux perl. Some programs write to the same line over and over, or something like PICO will allways have a menu on the bottom and will let you scroll your text. Or you'll have a little text animation, where one character on the screen constantly changes.

How can I do this, or under what programming topic do i research this? Cursors?

\r can be used for some things like this. Check out this whirlygig e-mail neshura	[reply]

I'm glad you understood that question... because I certainly didn't. Can anyone explain what we are talking about here? Thanks.	[reply]

You probably want the Curses module or one of the Term::* modules, but it's hard to tell.	[reply]

It has been said already, but curses is probably the thing you want here. If curses programming scares you, you could always have a look at CDK (Curses Development Kit). I've used it a few times, and it's quite good when you want results fast. It can be a bit hairy sometimes, but with practice... HTH! /dempa	[reply]

Hi Monks, Thanks for your replies. The \r escape worked fine?	[reply]

I'm not sure if this is what you want, but couldn't you just use a linefeed? Try this: `perl -e 'sleep 1, print STDERR ++$i, "\r" while $i < 9'` [download]	[reply] [d/l]
