NAME

Language::Homespring - Perl interpreter for "Homespring"

SYNOPSIS

use Language::Homespring;

my $hs = new Language::Homespring();
$hs->parse("bear hatchery Hello,. World ..\n powers");

# run one tick
print $hs->tick;

# run program until it ends or 1000 ticks are reached
$hs->run(1000);

DESCRIPTION

This module is an interpreter for the Homespring language. It currently only implements a small subset of the homespring language and is broken in places. The Hello World example in the "examples" folder works fine though :)

METHODS

new()

Creates a new Language::Homespring object, with a blank op-tree.

parse( $source )

Parses $source into an op-tree, discarding any previous op-tree.

tick()

Executes a single "turn" of the interpreter, returning any output as a scalar.

run( $limit )

Executes ticks until the universe is destroyed or the (optional) tick limit is reached. Output is sent to STDOUT;
