MadLisp
=======

[](#madlisp)

MadLisp is a [Lisp](https://en.wikipedia.org/wiki/Lisp_%28programming_language%29) interpreter written in PHP.

Requirements
------------

[](#requirements)

The project requires PHP 7.4 or newer and [Composer](https://getcomposer.org/).

Quickstart
----------

[](#quickstart)

Create a new directory and require the project using composer:

```
$ mkdir mylisp
$ cd mylisp
$ composer require peklaiho/madlisp

```

Use the `vendor/bin/madlisp` executable to start the interpreter. Start the REPL with the `-r` option:

```
$ vendor/bin/madlisp -r
>

```

You can evaluate Lisp code interactively inside the REPL:

```
> (+ 1 2 3)
6

```

Alternatively you can evaluate a file that contains Lisp code:

```
$ echo "(+ 1 2 3)" > mylisp.mad
$ vendor/bin/madlisp mylisp.mad
6

```

Documentation
-------------

[](#documentation)

The full [documentation](http://madlisp.com/) is available on the project website.

Status
------

[](#status)

The language seems stable at this point so I am releasing it as 1.0. Please report any issues.
