Thanks. I used [asciinema](https://asciinema.org/).

Nice work. How did you record it?

BTW, below are project generators for common lisp:

* http://quickdocs.org/cl-project/
* https://www.xach.com/lisp/quickproject/
* http://quickdocs.org/eazy-project/
* http://quickdocs.org/trivial-project/

Inspired by [this entry](https://www.reddit.com/r/lisp/comments/76d6vu/developing_http_api_with_cl_and_ningle_screencast/), I decided to record some late-night hacking.  Turns out it's too big for asciinema, so self-hosted. Small droplet, be gentle.

Apropos project generators a recent post from Leo Zovic http://langnostic.inaimathi.ca/posts/quickproject-revisions
