# DESCRIPTION

Language::l33t is a Perl interpreter of the l33t language created by
Stephen McGreal and Alex Mole. For the specifications of l33t, refer
to [Language::l33t::Specifications](https://metacpan.org/pod/Language%3A%3Al33t%3A%3ASpecifications).

# METHODS

## new( %options )

Creates a new interpreter. The options that can be passed to the function are:

- debug => $flag

    If $flag is set to true, the interpreter will print debugging information
    as it does its thing.

- stdin => $io

    Ties the stdin of the interpreter to the given object.

- stdout => $io

    Ties the stdout of the interpreter to the given object. 

    E.g.:

    ```perl
    my $output;
    open my $fh_output, '>', \$output;

    my $l33t = Language::l33t->new( stdout => $fh_output );

    $l33t->set_source( $code );
    $l33t->run;

    print "l33t output: $output";
    ```

- memory\_max\_size => $bytes

    The size of the block of memory available to interpreter. By default set to
    64K (as the specs recomment).

- byte\_size => $size

    The size of a byte in the memory used by the interpreter. Defaults to
    256 (so a memory byte can hold a value going from 0 to 255).

## source( $l33tcode )

Loads and "compiles" the string $l33tcode. If one program was already loaded,
it is clobbered by the newcomer. 

## run( \[ $nbr\_iterations \] )

Runs the loaded program. If $nbr\_iterations is given, interupts the program
after this number of iterations even if it hasn't terminated. Returns 0 in
case the program terminated by evaluating an END, 1 if it finished by reaching
$nbr\_iterations.

## reset

Reset the interpreter to its initial setting. Code is
recompiled, and pointers reset to their initial values. 

E.g.

```perl
my $l33t = Language::l33t->new();
$l33t->load( $code );
$l33t->run;

# to run the same code a second time
$l33t->reset;
$l33t->run;
```

## memory

Returns the memory of the interpreter in its current state as an array.

# DIAGNOSTICS

- F00l! teh c0d3 1s b1g3R th4n teh m3m0ry!!1!

    You tried to load a program that is too big to fit in 
    the memory. Note that at compile time, one byte is reserved
    for the memory buffer, so the program's size must be less than
    the memory size minus one byte.

- Byt3 s1z3 must be at l34st 11, n00b!

    The _byte\_size_ argument of _new()_ was less than 11. 
    The byte size of an interpreter must be at least 11 (to
    accomodate for the opcodes).

- L0L!!1!1!! n0 l33t pr0gr4m l04d3d, sUxX0r!

    run() called before any program was load()ed.

# THANKS 

It goes without saying, special thanks go 
to Stephen McGreal and Alex Mole for inventing l33t. 
They are teh rOxX0rs.
