"accessors" help
A bit about objects in Factor:
First take a look at this example from the homepage (the code sample is
different at each reload, keep trying):
USING: accessors kernel math math.constants
math.functions prettyprint ;
IN: shapes
TUPLE: circle radius ;
TUPLE: rectangle width height ;
GENERIC: area ( shape -- area )
M: circle area radius>> sq pi * ;
M: rectangle area [ width>> ] [ height>> ] bi * ;
rectangle new 10 >>width 20 >>height area .
In factor, methods and slots are logically separated from each other. If
you know Common Lisp and its CLOS this'll be familiar.
TUPLE: takes a name for the objects "class" you're defining, followed by
all of the slots that class of objects contains. That's how you declare a
"class".
GENERIC: takes a word name and a stack effect. That's how you declare a
name to be used for methods (as opposed to declaring a regular
word/function).
M: takes a "class" (something declared via TUPLE:), a method name
(something declared via GENERIC:), and a function body.
Let us know if you have any more questions after browsing the docs.
