Dice Programming Language


Dice Build Status

Java, but worse


  • The test environment is Ubuntu 16.04 running within Virtualbox
  • The following ubuntu packages were installed: m4 clang-3.8 llvm opam ocaml
  • The following opam packages were installed: core batteries llvm yojson

How to run the compiler

  • Make sure you are running Ubuntu 16.04 or equivalent
  • clone the repo:
    $ git clone https://github.com/DavidWatkins/Dice.git
  • Then install the required packages
    $ sudo apt-get install ocaml ocaml-native-compilers camlp4-extra opam m4 clang-3.8 llvm
  • Then initialize opam in your home directory
    $ opam init
    $ eval $(opam config env)
    $ opam install core batteries llvm.3.8 yojson ocamlfind
  • Then go into the Compiler directory and run the build script
    $ cd Dice
    $ make
  • Write a small Dice program
    class HelloWorld {
    public void main(char[][] args) {
      print("Hello World!");
  • Compile the code and then run it!
    $ ./dice input.dice
    $ lli input.ll
    Hello World!

To test the compiler

  • cd into tests and run tester.sh after having compiled the compiler
    $ make test

If you get an error: “error: expected value token” from lli

This means your version of lli is probably incorrect. Running “lli –version” should return 3.7, but if it doesn’t:

  • Run the following commands to remove the symlink of lli in your /usr/bin directory
    $ sudo rm \usr\bin\lli
    $ ln -s /usr/lib/llvm-3.8/bin/lli /usr/bin/lli
  • Now you should be able to use lli with the outputted llvm code from dice
