  eForth and Zen

  The first chapter of eForth and Zen. Some opening thoughts:

  Forth is often mentioned not only as a computer language but also a religion because of its fervorish followers. Among religions Zen is considered to be the closest to Forth. As popularly known Zen is understood as a synonym of simplicity, brevity, light, understanding, wisdom and enlightenment. These are also attributes to Forth as a language and a philosophy. Indeed, Zen and Forth also bear striking similarity in their historical development and evolution. This aspect of similarity between Forth and Zen has not been well documented, and this is one purpose of this book.

  Lisp in Ruby

  You got your Lisp in my Ruby! A Lisp has been constructed that can be run inside of any Ruby, composed of just lists, symbols, and a few methods. Here’s a list reverse function written in Ruby Lisp:

  require 'lisp'
  
  # Create an environment where the reverse, rev_shift and null
  # functions are bound to an appropriate identifier.
  env = [
    cons(:rev_shift,
      [:lambda, [:list, :result],
        [:cond,
          [[:null, :list], :result],
          [:t, [:rev_shift, [:cdr, :list],
              [:cons, [:car, :list], :result]]]]].sexp),
    cons(:reverse,
      [:lambda, [:list], [:rev_shift, :list, nil]].sexp),
    cons(:null, [:lambda, [:e], [:eq, :e, nil]].sexp),
    cons(:t, true), 
    cons(nil, nil)
  ].sexp
  
  # Evaluate an S-Expression and print the result
  exp = [:reverse, [:quote, [:a, :b, :c, :d, :e]]].sexp
  

  Here are the same definitons from env were they written in a traditional Lisp:

  (defun reverse (list)
    (rev-shift list nil))
  
  (defun rev-shift (list result)
    (cond ((null list) result)
          (t (rev-shift (cdr list) (cons (car list) result))) ))

  Reasonably accurate SLOC counter.

  Prints the number of line-blank lines in all matching files in the current directory. Modify as needed to work with other file types, it currently works with *.c and *.h files.

  perl -n -e 'print unless /^\s*$/' *.[ch] | wc -l

  Thanks, Perl and Lula mailing list.

  Compile Shooters

  From the Zanac NES manual:

  One day, someone opened the icon improperly. The system started operation and started attacking them. Then, they opened it properly. The icon ordered the system to suspend the attack. The system however ignored this order and became a slaughter device. The human beings who opened the icon fell into crisis. The attack from the system overwhelmed the offensive power of the human beings. When they were about to perish, there was one hope - the system is basically a strategic machine and is equipped for fighting against a multitude. If a single object confronts the system by itself, the system might not be able to cope with it effectively.

  Cinch: The IRC Microframework

  Cinch is an IRC Microframework for quickly creating IRC bots in Ruby with minimal effort. It provides a minimal interface based on plugins and rules. It’s as simple as creating a plugin, defining a rule, and watching your profits flourish.

  Inspired by other Ruby domain-specific languages for sure, but I could definitely see myself using this. I always have IRC bot ideas, and normally end up writing them from scratch in Python. Well, no more.

  Hero Core is the sequel to one of my favorite games of all time, Hero. It’s not complete yet, but from what the gameplay video shows I can see that it stays true to its predecessor.
