C’Dent - A Portable Module Programming Language

C’Dent is a programming language that:

1. Is primarily intended to write portable OO modules. C’Dent modules are written once, and then compiled to equivalent port modules in any number of supported programming languages.

2. Has multiple input syntaxes. Including defined subsets of: - Perl - Python - Ruby - JavaScript - Java

3. Compiles to a Common’DENominaTor tree form known as C’Dent. C’Dent is an OO model that has the notions of modules, classes, methods, and expressions.

4. Emits C’Dent trees to several existing programming languages, including: - C’Dent - the compiled tree form serialized as YAML or XML - Perl - Python - Ruby - JavaScript - PHP - Java - Perl 6 - Python 3 - C++ - CIL (.NET Common Intermediate Language) - PIR (Parrot Intermediate Runtime)

5. Uses static implicit typing to assign types to all objects at compile time, and throw syntax errors for type conflicts. Strong typing is required to generate equivalent code in the various emitted port languages.

INSTALLATION

Currently the best way to install C’Dent is to get the source code and install it like so:

> git clone git://github.com/ingydotnet/cdent.git
> cd cdent
> sudo setup.py install

USAGE

After you install C’Dent, you will have a cdent compiler in your Unix path. Try running this command:

cdent --help

You’ll need a program written in C’Dent. There are some in your C’Dent repository clone. One example is tests/modules/world.cd.py which looks like this:

"""\
This is World class :)
"""

class World():
    def greet(self):
        print "Hello, world"

You can compile to Ruby with this command:

cdent --compile --in=tests/modules/world.cd.py --to=rb

Which produces:

# *** DO NOT EDIT ***  This is a C'Dent generated Ruby module.
###
# This is World class :)
###

class World
    def greet
        puts("Hello, world")
    end
end

You can compile it to many other languages by changing the value of –to=.
