Lisp Koans
Common Lisp Koans is a language learning exercise
Lisp Koans is a self-guided learning path for Common Lisp that teaches the language’s idioms through a series of failing tests you progressively make pass. Each koan introduces a concept—symbols, lists, macros, multiple dispatch, reader syntax—then asks you to fill in the blanks and run the suite again. The feedback loop is intentionally tight: fail, reflect, fix, and rerun until the tests become a form of living documentation. Because koans are organized from fundamentals to metaprogramming, learners internalize not just syntax but also Lisp’s philosophy of code-as-data. The exercise format makes it ideal for workshops, katas, or leveling up engineers who have never touched a Lisp before. It’s minimal on infrastructure and maximal on discovery, encouraging use of a REPL and inspector while you solve each puzzle. -

COOK tool
Software build-automation tool written in Common Lisp
COOK is a software build-automation tool made with a goal of letting you, the programmer, to utilize the most elegant and powerful programming language - Common Lisp - for managing your software builds. You write a recipe file which describes what objectives must be constructed. COOK will load and process this file, then produce either a regular Makefile or a Bourne Shell script, which will actually perform the task of building and installing your targets. -
