# mal - Make a Lisp
## Description
**1. Mal is a Clojure inspired Lisp interpreter**
**2. Mal is a learning tool**
Each implementation of mal is separated into
11 incremental, self-contained (and testable) steps that demonstrate
core concepts of Lisp. The last step is capable of self-hosting
(running the mal implementation of mal). See the make-a-lisp process
guide.
The make-a-lisp steps are:
* step0_repl
* step1_read_print
* step2_eval
* step3_env
* step4_if_fn_do
* step5_tco
* step6_file
* step7_quote
* step8_macros
* step9_try
* stepA_mal
Each make-a-lisp step has an associated architectural diagram. That elements
that are new for that step are highlighted in red.
Here is the final architecture once step A
is complete:
If you are interested in creating a mal implementation (or just
interested in using mal for something) you are welcome to to join our
Discord. In addition to the make-a-lisp
process guide there is also a mal/make-a-lisp
FAQ where I attempt to answer some common questions.
