befunge-php
===========

[](#befunge-php)

[![befunge](doc/befunge.png)](doc/befunge.png)

Befunge is an esoteric programming language that operates in a 2d space, allowing the instruction pointer (ip) to point in any direction.

This interpreter is based on the funge-98 spec, and implements a non-concurrent two-dimensional variant of the language.

Example
-------

[](#example)

Hello world:

```
0"!dlroW ,olleH">:#,_@

```

Count:

```
v                                        @
> & 00p 0 10p ;; 0. ;; " ", ;; > 00g 10g w @
v                                        <
> 10g 1+ 10p ;; 10g. ;; " ",   ^

```

Usage
-----

[](#usage)

Just pass a filename to the interpreter:

```
$ bin/befunge examples/hello.b98

```

You can also pass the `--debug` option to get a log of all instructions.

```
$ bin/befunge --debug examples/hello.b98

```

Stability
---------

[](#stability)

Highly experimental, unstable, incomplete. PRs welcome.
