A next-gen programming language that enables massive collaborative development.

Currently Cortex is in alpha. It is expected to reach v1.0 status by the end of 2015. The project has been validated on the following platforms:

• Ubuntu 14.04 (32/64 bit)
• OS X 10.10.2 (64 bit)

Download and unpack Cortex on your machine. Run the following commands to build it:

source configure
make clean all

Cortex depends on the following packages - make sure to have them installed:

• flex
• bison
• libxml2-dev (only required for building)

Put the following code snippets in file with the extension cx. Execute the code with cortex foo.cx.

"Hi Cortex!"

prints: Hi Cortex!

struct Point::      // Create a new composite type
   x, y: int32

Point imHere: 1, 2  // Create an object
"$imHere"           // Print object value

prints: {1,2}

int32 a                       // A primitive object
a := 10                       // Assign 10 & trigger an event
on update a: "A triggered!"   // Observer of a

Run the following commands to create a new C package called StarWars

cxgen --package --lang c StarWars

You'll find a new directory called 'StarWars' with the following structure:

StarWars/
├── StarWars.cx
├── makefile
├── src/
│   ├── StarWars__api.c
│   ├── StarWars__load.c
│   └── StarWars__meta.c
└── include/
    ├── StarWars__api.h
    ├── StarWars__meta.h
    └── StarWars__type.h

When inspecting the StarWars.cx file, you'll find:

#package ::StarWars

Add the following lines to this StarWars.cx:

enum SpaceShipKind:: XWing, MilleniumFalcon, Destroyer, DeathStar 

class SpaceShip::
    kind: SpaceShipKind
    hp: int32, readonly
    strength: int32, readonly
    int16 construct()
    void attack(SpaceShip target)

Run make -C StarWars to re-generate and make the package. Notice that there are now two additional files:

StarWars/
├── src/
│   └── StarWars_SpaceShip.c
└── include/
    └── StarWars_SpaceShip.h

In StarWars_SpaceShip.c, add the following code to the StarWars_SpaceShip_construct method between the $begin and $end markers:

/* $begin(::StarWars::SpaceShip::construct) */
    switch(_this->kind) {
    case StarWars_XWing:
       _this->hp = 100;
       _this->strength = 500;
       break;
    case StarWars_MilleniumFalcon:
       _this->hp = 500;
       _this->strength = 1000;
       break;
    case StarWars_Destroyer:
       _this->hp = 3000;
       _this->strength = 5000;
       break;
    case StarWars_DeathStar:
       _this->hp = 2000000000;
       _this->strength = 2000000000;
       break;
    }
    return 0;
/* $end */

In the StarWars_SpaceShip_attack method, add the following code:

/* $begin(::StarWars::SpaceShip::attack) */
    if ((_this->kind == StarWars_MilleniumFalcon) && (target->kind == StarWars_DeathStar)) {
        target->hp = 0;
    } else if (_this->strength > target->hp) {
        target->hp = 0;
    } else {
        target->hp -= _this->strength;
    }
    if (!target->hp) {
        printf("%s: I have defeated %s!\n", cx_nameof(_this), cx_nameof(target));
    } else {
        if (target->hp <= 500) {
            printf("%s: May the force be with me\n", cx_nameof(target));
        } else if (target->hp <= 1000) {
            printf("%s: Taking some serious damage...\n", cx_nameof(target));
        } else {
            printf("%s: It's just a flesh wound\n", cx_nameof(target));
        }
    }
/* $end */

That's it! Run make -C StarWars again. You can now use this package in scripts!

Try it out with a new file called epicbattle.cx, add the following (historically incorrect) lines:

StarWars::SpaceShip Luke: XWing
StarWars::SpaceShip DarthVader: Destroyer

while DarthVader.hp: Luke.attack(DarthVader)

Run the script with cortex epicbattle.cx. Your output should look like:

DarthVader: It's just a flesh wound
DarthVader: It's just a flesh wound
DarthVader: It's just a flesh wound
DarthVader: Taking some serious damage...
DarthVader: May the force be with me
Luke: I have defeated DarthVader!

You can also run the above script in our interactive interpreter. Just run cxsh and start entering code!
