# Scarab
# A little turtle graphics language for Cairo
#
# Christian Koch <cfkoch@sdf.lonestar.org>
#
Scarab implements a tiny and relatively featureless scripting language as a
front-end to the Cairo vector graphics library. Expect more features to come in
the near future.
The Scarab language has a simple, intuitive, and inflexible syntax. It is
imperative in nature; every instruction consists of a command name followed by
zero or more arguments. Commands are separated by newlines. The entire language
reference is listed here.
line x y
Draw a line from the current location to (x, y).
move x y
Move the pen to the location (x, y).
paint
Paint the entire canvas the current color. For example, to make the canvas
solid black:
source 0.0 0.0 0.0
paint
source r g b
Set the color of the pen. Red, green, and blue components are floating-point
numbers with a range of [0.0, 1.0]. For example, to set the color of the pen
to blue:
source 0.0 0.0 1.0
stroke
The `line' command draws a line, but it is not visible until we call this
command. It is not necessary to call `stroke' after every call to `line'.
