Mal is a learning tool. See the [make-a-lisp process
|
|
guide](process/guide.md). 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).
|
|
|
|
The mal (make a lisp) steps are:
|
|
|
|
* [step0_repl](process/guide.md#step0)
|
|
* [step1_read_print](process/guide.md#step1)
|
|
* [step2_eval](process/guide.md#step2)
|
|
* [step3_env](process/guide.md#step3)
|
|
* [step4_if_fn_do](process/guide.md#step4)
|
|
* [step5_tco](process/guide.md#step5)
|
|
* [step6_file](process/guide.md#step6)
|
|
* [step7_quote](process/guide.md#step7)
|
|
* [step8_macros](process/guide.md#step8)
|
|
* [step9_try](process/guide.md#step9)
|
|
* [stepA_mal](process/guide.md#stepA)
|
|
|
|
|
|
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](https://www.youtube.com/watch?v=lgyOAiRtZGw),

|
|
Joel gave a presentation on "Make Your Own Lisp Interpreter in
|
|
10 Incremental Steps" at LambdaConf 2016: [Part

If you are interesting in creating a mal implementation (or just
|
|
interested in using mal for something), please drop by the #mal
|
|
channel on freenode. In addition to the [make-a-lisp process
|
|
guide](process/guide.md) there is also a [mal/make-a-lisp
|
|
FAQ](docs/FAQ.md) where I attempt to answer some common questions.
|
|
|
|
## Building/running implementations
|
|
|
|
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 convenience
|
|
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"
|
|
```
|
|
|
|
|
|
### Ada
|
|
|
|
*The Ada implementation was created by [Chris Moore](https://github.com/zmower)*
|
|
|
|
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).
|
|
|
|
```
|
|
cd ada
|
|
make
|
|
./stepX_YYY
|
|
```
|
|
|
|
### GNU awk
|
|
|
|
*The GNU awk implementation was created by [Miutsuru kariya](https://github.com/kariya-mitsuru)*
|
|
|
|
The GNU awk implementation of mal has been tested with GNU awk 4.1.1.
|
|
|
|
```
|
|
cd gawk
|
|
gawk -O -f stepX_YYY.awk
|
|
```
|
|
|
|
### Bash 4
|
|
|
|
```
|
|
cd bash
|
|
bash stepX_YYY.sh
|
|
```
|
|
|
|
### BASIC (C64 and QBasic)
|
|
|
|
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](https://github.com/kanaka/cbmbasic) (the patched version is
|
|
currently required to fix issues with line input) and the QBasic mode
|
|
has been tested with [qb64](http://www.qb64.net/).
|
|
|
|
Generate C64 code and run it using cbmbasic:
|
|
|
|
```
|
|
cd basic
|
|
make stepX_YYY.bas
|
|
STEP=stepX_YYY ./run
|
|
```
|
|
|
|
Generate QBasic code and load it into qb64:
|
|
|
|
```
|
|
cd basic
|
|
make MODE=qbasic stepX_YYY.bas
|
|
./qb64 stepX_YYY.bas
|
|
```
|
|
|
|
Thanks to [Steven Syrek](https://github.com/sjsyrek) for the original
|
|
inspiration for this implementation.
|
|
|
|
|
|
### C
|
|
|
|
The C implementation of mal requires the following libraries (lib and
|
|
header packages): glib, libffi6, libgc, and either the libedit or GNU readline
|
|
library.
|
|
|
|
```
|
|
cd c
|
|
make
|
|
./stepX_YYY
|
|
```
|
|
|
|
### C++
|
|
|
|
*The C++ implementation was created by [Stephen Thirlwall (sdt)](https://github.com/sdt)*
|
|
|
|
The C++ implementation of mal requires g++-4.9 or clang++-3.5 and
|
|
a readline compatible library to build. See the `cpp/README.md` for
|
|
more details:
|
|
|
|
```
|
|
cd cpp
|
|
make
|
|
# OR
|
|
make CXX=clang++-3.5
|
|
./stepX_YYY
|
|
```
|
|
|
|
|
|
### C# ###
|
|
|
|
The C# implementation of mal has been tested on Linux using the Mono
|
|
C# compiler (mcs) and the Mono runtime (version 2.10.8.1). Both are
|
|
required to build and run the C# implementation.
|
|
|
|
```
|
|
cd cs
|
|
make
|
|
mono ./stepX_YYY.exe
|
|
```
|
|
|
|
### ChucK

|
|
|
|
```
|
|
cd chuck
|
|
./run
|
|
```
|
|
|
|
### Common Lisp
|
|
|
|
*The Common Lisp implementation was created by [Iqbal Ansari](https://github.com/iqbalansari)*
|
|
|
|
The implementation has been tested with SBCL, CCL, CMUCL, GNU CLISP, ECL and
|
|
Allegro CL on Ubuntu 16.04 and Ubuntu 12.04, see
|
|
the [README][common-lisp/README.org] for more details. Provided you have the
|
|
dependencies mentioned installed, do the following to run the implementation
|
|
|
|
```
|
|
cd common-lisp
|
|
make
|
|
./run
|
|
```
|
|
|
|
### Clojure
|
|
|
|
For the most part the Clojure implementation requires Clojure 1.5,
|
|
however, to pass all tests, Clojure 1.8.0-RC4 is required.
|
|
|
|
```
|
|
cd clojure
|
|
lein with-profile +stepX trampoline run
|
|
```
|
|
|
|
### CoffeeScript
|
|
|
|
```
|
|
sudo npm install -g coffee-script
|
|
cd coffee
|
|
coffee ./stepX_YYY
|
|
```
|
|
|
|

# OR
|
|
make # needed to run tests
|
|
./stepX_YYY
|
|
```
|
|
|
|
### D
|
|
|
|
*The D implementation was created by [Dov Murik](https://github.com/dubek)*
|
|
|
|

make
|
|
./stepX_YYY
|
|

|
|
and 24.5. While there is very basic readline editing (`<backspace>`
|
|
and `C-d` work, `C-c` cancels the process), it is recommended to use
|
|
`rlwrap`.
|
|
|
|
```
|
|
cd elisp
|
|
emacs -Q --batch --load stepX_YYY.el
|
|
# with full readline support
|

|
|
and [rebar](https://github.com/rebar/rebar) to build.
|
|
|
|
```
|
|
cd erlang
|
|
make
|
|
# OR

|
The F# implementation of mal has been tested on Linux using the Mono
|
|
F# compiler (fsharpc) and the Mono runtime (version 3.12.1). The mono C#
|
|
compiler (mcs) is also necessary to compile the readline dependency. All are
|
|
required to build and run the F# implementation.

|
```
|
|
|
|
### PL/pgSQL (Postgres SQL Procedural Language)
|
|
|
|
The PL/pgSQL implementation of mal requires a running Postgres server
|
|
(the "kanaka/mal-test-plpgsql" docker image automatically starts
|
|
a Postgres server). The implementation connects to the Postgres 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 Postgres 9.4.
|
|
|
|
```
|
|
cd plpgsql
|
|
./wrap.sh stepX_YYY.sql
|
|
# OR
|
|
PSQL_USER=myuser PGPASSWORD=mypass ./wrap.sh stepX_YYY.sql
|
|
```
|
|
|
|
### PL/SQL (Oracle SQL Procedural Language)
|
|
|
|
The PL/pgSQL 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.
|
|
|
|
```
|
|
cd plsql
|
|
./wrap.sh stepX_YYY.sql
|
|
# OR
|
|
ORACLE_LOGON=myuser/mypass@ORCL ./wrap.sh stepX_YYY.sql
|
|
```
|
|
|

## Running tests
|
|
|
|
### Functional tests
|
|
|
|
The are over 600 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 simplify the process of running tests, a top level Makefile is
|
|
provided with convenient test targets.
|
|
|
|
* 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"
|
|
```
|
|
|
|
### Self-hosted functional tests
|
|
|
|
* To run the functional tests in self-hosted mode, you specify `mal`
|
|
as the test implementation and use the `MAL_IMPL` make 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=python "test^mal^step2"
|
|
```
|
|
|
|
### Starting the REPL
|
|
|
|
* 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 `stepA` is used:
|
|
|
|
```
|
|
make "repl^IMPL"
|
|
|
|
# e.g
|
|
make "repl^ruby"
|
|
make "repl^ps"
|
|
```
|
|
|
|
* To start the REPL of the self-hosted implementation, specify `mal` as the
|
|
REPL implementation and use the `MAL_IMPL` make 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=python "repl^mal"
|
|
```
|
|
|
|
### Performance tests
|
|
|
|
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"
|
|
```
|
|
|
|
### Generating language statistics
|
|
|
|
* To report line and byte statistics for a single implementation:
|
|
```
|
|
make "stats^IMPL"
|
|
|
|
# e.g.
|
|
make "stats^js"
|
|
```
|
|
|
|
* To report line and bytes statistics for general Lisp code (env, core
|
|
and stepA):
|
|
```
|
|
make "stats-lisp^IMPL"
|
|
|
|
# e.g.
|
|
make "stats-lisp^js"
|
|
```
|
|
|
|
## Dockerized testing
|
|
|
|
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 *"kanaka/mal-test-IMPL"*
|
|
* JVM-based language implementations (Groovy, Java, Clojure, Scala):
|
|
you will probably need to run these implementations 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 download to dot-files in the /mal
|
|
directory so they will persist between runs.
