Is Lisp Difficult?
- D. A 0F )
Never!
Not at all!

10. - D. A 0F )
Lisp is very simple language
It is little bit difficult for novice
to learn because of
less opportunities to train
But
Introduce a Lisp Training Tool

15. Lisp-Koans
- D. A 0F )
Common Lisp Koans is a language learning exercise in the same vein as the ruby
koans, python koans and others. It is a port of the prior koans with some
modifications to highlight lisp-specific features. Structured as ordered groups of
broken unit tests, the project guides the learner progressively through many
Common Lisp language features.

How to setup and use
Lisp-Koan

21. Setup Learning Environment
- D. A 0F )
Lisp-Koans is designed for Linux or MacOS
(It’s recommended to use virtual env software if you use windowssystem )
1. Download and setup HomeBrew or LinuxBrew
2. Install Roswell 3. Install fswatch
HomeBrew: https://brew.sh/ LinuxBrew: http://linuxbrew.sh/
brew install roswell brew install fswatch
5. Download Lisp-Koans
git clone https://github.com/google/lisp-koans.git
4. Making Path for Lisp Implementation
echo “export $PATH:$HOME/.roswell/impls/****/****/sbcl-bin/
1.4.4/bin”
Launch Lisp-koans (with file surveillance)
- D. A 0F )
MacOS: sh /path/to/lisp-koans/mediation-macos.sh
On Terminal Emulator
Linux: sh /path/to/lisp-koans/mediation-linux.sh
1. Launch lisp-koans surveilance agent
emacs /path/to/lisp-koans/koans/asserts.lsp
2. Open mediation target file with any text editor
(assert-true ___) → (assert-true t )
3. Edit(mediate) target file
TEST-TRUE-OR-FALSE requires more meditation
4. Check feedbacks

Impressions of Lisp-Koans
- D. A 0F )
It’s not good for absolute beginners
If they don’t know basic concept and syntax…
It’s not good for experts
There are not remarkable lessons for experts
It’s good for elementary learner
They can learn syntax and well-formed program in practical program
Less mediation codes
It’s not enough questions to understand CL. e.g.:
