How Factor implements closures
The recent blog post from the Clozure CL team on Clozure CL's implementation of closures inspired me to do a similar writeup about Factor's implementation. It is often said that "closures are a poor man's objects", or "objects are a poor man's closures". Factor takes the former view, because as you will see they are largely implemented within the object system itself. Quotations First, let us look
Beginning Factor – Introduction
I’ve been involved in the Factor programming language community for about a year now, and am constantly amazed with how productive its contributors are. Large improvements to the language and its libraries are made on a weekly (if not daily) basis, and it’s finally starting to attract some much-deserved attention from the programming community. The problem is, the language is a huge departure from

Useless Factor: Factor supports XML literal syntax
Factor can now express XML as literals in code. There's a new library, xml.interpolate, which lets you create an XML chunk or document using interpolating either by locals or using a fry-like syntax. Here's a taste, from the syndication vocab, to create an Atom file:: feed>xml ( feed -- xml ) [ title>> ] [ url>> present ] [ entries>> [ entry>xml ] map ] tri <XML <feed xmlns="http://www.w3.org/2005
Beginning Factor – Shufflers & Combinators
In the previous installment of Beginning Factor, we discussed some of the attributes of stack-based languages and the syntax for defining words in Factor. This time around, I’d like to introduce stack shufflers, quotations & combinators, and touch on some more basic data types and their properties. Up until now, we’ve essentially been using Factor as an overqualified RPN calculator. I just wanted
Factor: an extensible interactive language | Lambda the Ultimate
Factor: an extensible interactive language, Google Tech Talk by Slava Pestov. Factor is a general-purpose programming language which has been in development for a little over five years and is influenced by Forth, Lisp, and Smalltalk. Factor takes the best ideas from Forth -- simplicity, succinct code, emphasis on interactive testing, meta-programming -- and brings modern high-level language featu
Eggs Unlimited - stacktor
Version 0.8 Release fix 0.7 Meta-file fix 0.6 Documentation fix 0.5 Initial release Documentation Stacktor allows programmers to use stack based programming next to more familiar styles of programming such as functional, imperative, object-oriented, etc. In stack programming, arguments are taken from the stack, and return values are pushed back on to the stack. Literal values are automatically pus
New mark-compact algorithms
It'd be good for a garbage collector to have low space overhead, good cache behavior and low fragmentation. Low space overhead is useful wherever there's a limited amount of RAM. Eliminating fragmentation is important, since fragmentation reduces the usable amount of memory and can make allocation slower. Improving cache behavior of ordinary programs is always good for performance, and surprisingl
