port request: 'asciinema'

[KurtPfeifle (Kurt Pfeifle)]

The 'asciinema' utility is very handy for recording terminal key strokes and related output for later demonstration or teaching/sharing purposes.

The following command will start the recording of a terminal session (which can be ended by typing "exit" or hitting 'ctrl+D'):

asciinema rec -w 1 my.session

The -w 1 parameter will limit periods of non-activity to 1 second max. The next command will replay the same session:

asciinema play my.session

The software is Free (GPL3), with source code (written in Go and JavaScript) on GitHub:

The files it writes ('my.session' above) are Unicode text files, and can easily be edited after recording (f.e. to fix typos).

You can view one asciinema screencast which I made yesterday here:
