There’s a great project called the Ruby Koans, it’s a series of tasks to exercise yourself in the Ruby language, stepping you through the standard library using the Ruby Unit Testing suite as a learning tool. It’s a great project.
I’d love to see something similar for Emacs.
Can anyone recommend any Lisp exercises to be done inside of Emacs to both exercise Lisp and Emacs usage? Perhaps also while completing the Ruby Koans?
There used to be lesson in .el format (emacs lisp) at http://www.gnuvola.org/software/elisp-tutorial/.
You can find a copy of the tutorial here now.
I learned a lot from them. You read them in emacs in lisp interactive mode, and practice within the text.
