PRM
From Wikipedia, the free encyclopedia
PRM stands for "Program with Refinement and Modules". It is a statically typed object-oriented programming language. The goal of PRM is to propose a statically typed programming language where structure is not a pain.
PRM has a simple straightforward style and can usually be picked up quickly, particularly by anyone who has programmed before. While object-oriented, it allows procedural styles.
The PRM Compiler (prmc) produces efficient machine language binaries. Currently, prmc is a prototype written in Ruby, but a new version written in PRM is planed for this summer.
Some PRM features:
- Pure Object-Oriented.
- Multiple Inheritance.
- Genericity.
- Realistic typing policy (as Eiffel).
- Fine property visibility (as Eiffel).
- Light and clear syntax.
- Easy C binding.
class Int
# This is not a class introduction, but a class refinement
# This refinement add the fibo function to primitives Int
def fibo : Int
# the well known fibo function, why a so basic example ...
do
if self < 1 then
return 0
elsif self = 1 then
return 1
else
return (self - 1).fibo + (self - 2).fibo
end
end
end
