alpha_sapphire is a toy programming language concept. Designed for minimal syntax and fully object-oriented expressiveness a-la Smalltalk and Ruby.

Things trying to archieve:

• Everything should be an object
• Meta-programming should be easy
• Syntax shold be minimal yet expressive
• Should be inspired by Smalltalk and Ruby
• Should give the power to the programmer, not limit him

The following is a collection of notes generated while learning CHICKEN Scheme.

Syntax

Function definition using defun:

(define (my-name arg1 arg2)
  (body...))

Functions that return true (#t) or false (#f) are called predicates:

(define-syntax hash
  (er-macro-transformer
   (lambda (expr r c) ; expression rename compare
     (let ((body  (cdr expr)))
       ;; code-expansion, self-executable lambda
       `(((lambda ()
	    (let ((table make-strong-eq-hash-table))
	      ,(let loop
		   ((pairs body))
		 (if (> (length pairs) 2)

1. Add packman packages
2. Install Infinality
3. Install "build essentials": sudo zypper in --type pattern devel_basis
4. Install Linuxbrew (to install apps which might not be in zypper, or to install them in $HOME)
5. Get Dropbox: sudo zypper in Dropbox && dropbox start -i
6. Get Source Code Pro font
7. Set "Source Code Pro" as default monospace font, "Roboto" as default sans-serif and "Droid Serif" as default serif.
8. Configure gnome shell as login shell and set up base16
9. Use numix theme with elementary icons or paper icons
10. Set up development environment

alpha_sapphire

Simplistic, interpreted, dynamic, object-oriented language inspired by Ruby and Coffeescript.

Simplistic

While trying to be expressive, the main focus on alpha_sapphire's syntax is to keep it simple. There is always a trade-off between expresiveness and complexity. For instance:

foo() unless bar == 2

Is more expressive than:

Usage: zf PATTERN [DIR]

Example: zf foo app/

Paste this somewhere. I use it in /usr/local/bin. Remeber to chmod +x /usr/local/bin/zf.

if [ -z "$1" ]
  then
 echo "usage: zf PATTERN [DIR]"
