Q1: is there a way to download the resulting screencast so that it can be viewed off the network? Q2: is there a way to do this without having to upload anything? e.g. pipe to a file locally?

try script(1) and scriptreplay(1)

Or ttyrec(1) and ttyplay(1)

Wow! This is quite awesome! Would love to have live streaming capability for this (though I can't think about a reason to use it yet, but I'm sure it'll be handy.)

Actually, I am working on something similar i.e being able to share terminals using browser.

So if you can work out how to add a red ● to your prompt, this'd be a really good way to indicate recording.

That's easy enough:

    PS1=`printf "\033[1;31m\342\227\217\033[0m\\$ "` sh

I've been thinking of better ways to do programming tutorials and something like this is roughly what I had in mind. Thanks for open sourcing it!

If you are interested in seeing code examples from a text editor or IDE we are working on Storyteller:

http://www.storytellersoftware.com

Everything is stored locally and the tool can generate an HTML playback file that can be passed around. One can also make comments during the playback. There tends not to be a great place to document how code evolves, we think a playback is the best place for this.

Its not quite ready for prime time yet but it will be soon. Our long term goals are to make a web app to store playbacks and to make it the next generation of version control.

Author of term.js/tty.js[1] here. Nice work. You guys should keep an eye on term.js. The version you're using is slightly old and actually contains a bug (now fixed) wherein all events will become unbound if the reset control sequence is received. I'm also adding fixes for a few other things currently, such as double-width character support, which has been a problem in the past.

Thanks, I was missing the printf.

Hey chjj, thank you so much for tty.js! You definitely deserve the credit for doing all the hard work :).

Cool! Realtime terminal hacking... now that's something I can use.
