Cupcake is a compiler for Jonathan Blows new programming language JAI. The compiler is built from the ideas and temporary specification that Blow has given in his Youtube and Twitch videos. Cupcake has almost everything implemented that Jonathan Blow has shown in his videos so far (2016-06-12).

Both Cupcake and me has no association with Jonathan Blow or JAIs development. The experience you have with Cupcake should not be reflected towards JAI and your opinion of it, Cupcake is not JAI. Cupcake is my hobby project, created for me to learn how a compiler works and how programs goes from source code to machine code.

More platforms will be supported later. There is a lot of windows specific code in this release and it will take a while to port everything over.

Here is the latest release: Cupcake v0.1-alpha.

1. Download the latest release.
2. Unpack in a seperate folder.
3. Run the compiler through the console.

cupcake main.jai

Usage: cupcake <source>... [options]
Options:
  -v --version           Show version
  -h --help              Show this screen
     --nologo            Disable Cupcake logo
  -r --run <code>        Executes the code
  -l --modules <path>    Include modules from folder [include already: ./modules/]
  -m --module <file>     Include module

Cupcake, as JAI, does not generate machine code (yet). There are two ways to execute your code, run the code in the compiler itself through bytecode (#run) or compile/convert your JAI code to C++ code. Currently a C++ file will always be generated and there is no way to turn it off. The output location for the C++ file is %EXECUTABLE_PATH%/output/output.cpp, the location can be changed by using the compiler workspace feature.

The release includes a few examples, but there is no other documentation available to Cupcake. The game example is the invaders game Jonathan Blow showed in the first few demos. To test the examples just type this in to the console.

cupcake examples/EXAMPLE_NAME/main.jai

Because the specification for JAI is not complete, writing a documentation is stupid. Though some nice people have written stuff about the language that could be used as documentation.

After using Cupcake, if you have any nice code examples, please send them to [email protected] and I added them to the examples folder.

The progress of JAI features that Cupcake has:

The goal is to make Cupcake as great as possible and to do that i need your help. If you find any problems/bugs, please report them and don't forget to send example code that demonstrates the problem. You can use the Github issue section or send me an email at [email protected] (use the email if you don't want the demonstration source code to be public).

For now I have decided to not release the source code. Why, because I don't know if it would be fair to Jonathan Blow and I am not very proud of the quality of the code. There is a huge amount of unnecessary code that could and should be removed, Cupcake v0.1-alpha is around 45k LOC.
