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.
3. Mal is implemented in 88 languages (94 different implementations and 117 runtime modes)
Mal was presented publicly for the first time in a lightning talk at Clojure West 2014 (unfortunately there is no video). See examples/clojurewest2014.mal for the presentation that was given at the conference (yes, the presentation is a mal program).
At Midwest.io 2015, Joel Martin gave a presentation on Mal titled "Achievement Unlocked: A Better Path to Language Learning". Video, Slides.
More recently Joel gave a presentation on "Make Your Own Lisp Interpreter in 10 Incremental Steps" at LambdaConf 2016: Part 1, Part 2, Part 3, Part 4, Slides.
The simplest way to run any given implementation is to use docker. Every implementation has a docker image pre-built with language dependencies installed. You can launch the REPL using a convenient target in the top level Makefile (where IMPL is the implementation directory name and stepX is the step to run):
make DOCKERIZE=1 "repl^IMPL^stepX"
# OR stepA is the default step:
make DOCKERIZE=1 "repl^IMPL"
The following implementations are maintained as separate projects:
- by Tim Morgan
- by vi - using Pest grammar, not using typical Mal infrastructure (cargo-ized steps and built-in converted tests).
- by Keith Rollin - This implementation used to be in the repo. However, Swift 2 is no longer easily buildable/testable.
- by Ali Mohammad Pur - The Q implementation works fine but it requires a proprietary manual download that can't be Dockerized (or integrated into the mal CI pipeline) so for now it remains a separate project.
- malc - Mal (Make A Lisp) compiler. Compiles a Mal program to LLVM assembly language, then binary.
- malcc - malcc is an incremental compiler implementation for the Mal language. It uses the Tiny C Compiler as the compiler backend and has full support for the Mal language, including macros, tail-call elimination, and even run-time eval. "I Built a Lisp Compiler" post about the process.
- frock - Clojure-flavoured PHP. Uses mal/php to run programs.
- flk - A LISP that runs wherever Bash is
- glisp - Self-bootstrapping graphic design tool on Lisp. Live Demo
The Ada implementation was developed with GNAT 4.9 on debian. It also compiles unchanged on windows if you have windows versions of git, GNAT and (optionally) make. There are no external dependencies (readline not implemented).

The BASIC implementation uses a preprocessor that can generate BASIC code that is compatible with both C64 BASIC (CBM v2) and QBasic. The C64 mode has been tested with cbmbasic (the patched version is currently required to fix issues with line input) and the QBasic mode has been tested with qb64.
Generate C64 code and run it using cbmbasic:
cd impls/basic
make stepX_YYY.bas
STEP=stepX_YYY ./run
Generate QBasic code and load it into qb64:
cd impls/basic
make MODE=qbasic stepX_YYY.bas
./qb64 stepX_YYY.bas
Thanks to Steven Syrek for the original inspiration for this implementation.
The BBC BASIC V implementation can run in the Brandy interpreter:
cd impls/bbc-basic

The PL/pgSQL implementation of mal requires a running PostgreSQL server (the "kanaka/mal-test-plpgsql" docker image automatically starts a PostgreSQL server). The implementation connects to the PostgreSQL server and create a database named "mal" to store tables and stored procedures. The wrapper script uses the psql command to connect to the server and defaults to the user "postgres" but this can be overridden with the PSQL_USER environment variable. A password can be specified using the PGPASSWORD environment variable. The implementation has been tested with PostgreSQL 9.4.
cd impls/plpgsql
./wrap.sh stepX_YYY.sql
# OR
PSQL_USER=myuser PGPASSWORD=mypass ./wrap.sh stepX_YYY.sql
The PL/SQL implementation of mal requires a running Oracle DB server (the "kanaka/mal-test-plsql" docker image automatically starts an Oracle Express server). The implementation connects to the Oracle server to create types, tables and stored procedures. The default SQL*Plus logon value (username/password@connect_identifier) is "system/oracle" but this can be overridden with the ORACLE_LOGON environment variable. The implementation has been tested with Oracle Express Edition 11g Release 2. Note that any SQL*Plus connection warnings (user password expiration, etc) will interfere with the ability of the wrapper script to communicate with the DB.

The top level Makefile has a number of useful targets to assist with
implementation development and testing. The help target provides
a list of the targets and options:
make help
The are almost 800 generic functional tests (for all implementations)
in the tests/ directory. Each step has a corresponding test file
containing tests specific to that step. The runtest.py test harness
launches a Mal step implementation and then feeds the tests one at
a time to the implementation and compares the output/return value to
the expected output/return value.
- To run all the tests across all implementations (be prepared to wait):
make test
- To run all tests against a single implementation:
make "test^IMPL"
# e.g.
make "test^clojure"
make "test^js"
- To run tests for a single step against all implementations:
make "test^stepX"
# e.g.
make "test^step2"
make "test^step7"
- To run tests for a specific step against a single implementation:
make "test^IMPL^stepX"
# e.g
make "test^ruby^step3"
make "test^ps^step4"
- To run the functional tests in self-hosted mode, you specify
malas the test implementation and use theMAL_IMPLmake variable to change the underlying host language (default is JavaScript):
make MAL_IMPL=IMPL "test^mal^step2"
# e.g.
make "test^mal^step2" # js is default
make MAL_IMPL=ruby "test^mal^step2"
make MAL_IMPL=python3 "test^mal^step2"
- To start the REPL of an implementation in a specific step:
make "repl^IMPL^stepX"
# e.g
make "repl^ruby^step3"
make "repl^ps^step4"
- If you omit the step, then
stepAis used:
make "repl^IMPL"
# e.g
make "repl^ruby"
make "repl^ps"
- To start the REPL of the self-hosted implementation, specify
malas the REPL implementation and use theMAL_IMPLmake variable to change the underlying host language (default is JavaScript):
make MAL_IMPL=IMPL "repl^mal^stepX"
# e.g.
make "repl^mal^step2" # js is default
make MAL_IMPL=ruby "repl^mal^step2"
make MAL_IMPL=python3 "repl^mal"
Warning: These performance tests are neither statistically valid nor comprehensive; runtime performance is a not a primary goal of mal. If you draw any serious conclusions from these performance tests, then please contact me about some amazing oceanfront property in Kansas that I'm willing to sell you for cheap.
- To run performance tests against a single implementation:
make "perf^IMPL"
# e.g.
make "perf^js"
- To run performance tests against all implementations:
make "perf"
- To report line and byte statistics for a single implementation:
make "stats^IMPL"
# e.g.
make "stats^js"
Every implementation directory contains a Dockerfile to create a docker image containing all the dependencies for that implementation. In addition, the top-level Makefile contains support for running the tests target (and perf, stats, repl, etc) within a docker container for that implementation by passing "DOCKERIZE=1" on the make command line. For example:
make DOCKERIZE=1 "test^js^step3"
Existing implementations already have docker images built and pushed to the docker registry. However, if you wish to build or rebuild a docker image locally, the toplevel Makefile provides a rule for building docker images:
make "docker-build^IMPL"
Notes:
- Docker images are named "ghcr.io/kanaka/mal-test-IMPL"
- JVM-based language implementations (Groovy, Java, Clojure, Scala):
you will probably need to run this command once manually
first
make DOCKERIZE=1 "repl^IMPL"before you can run tests because runtime dependencies need to be downloaded to avoid the tests timing out. These dependencies are downloaded to dot-files in the /mal directory so they will persist between runs.
