Live coding screencasts are way more awesome when the text can be copied. asciinema makes this possible.
The ability to copy and paste from video like this is tremendously awesome! Because it’s text-based, it also looks like I can annotate it with Hypothes.is too. Example: https://hyp.is/-Ay6wD7nEemnq3uyMRrhrA/asciinema.org/a/3uHCusbqQd6KAYNZ15NSv21bQ
This could be an awesome teaching tool, particularly for programming.
