This is the provided git repository for the WACC compilers lab. You should work in this repository regularly committing and pushing your work back to GitLab.

Provided files/directories

test line.

project

The project directory contains the build.properties and plugins.sbt files used by SBT:

• build.properties: sets which version of SBT will be used for the project
• plugins.sbt: adds plugins to SBT, by default you probably want sbt-assembly, which can be used to compile "Fat Runnable Jars", and then I've added sbt-git as well, which is handy in that it allows you to run git commands directly in a running sbt session. Using a fat jar is useful, as it doesn't require any classpath magic when running the program -- all dependencies are packaged within the jar.

src/main

The src/main directory is where you code for your compiler should go, and just contains a README and a stub hello world file with a simple calculator inside.

src/test

The src/test directory is where you should put the code for your tests, which can be ran via sbt test. The suggested framework is scalatest, the dependency for which has already been included.

build.sbt

The build.sbt is the definition of your project's build requirements. By default, this template has added the latest stable versions of both scalatest and parsley to the build: you should check regularly to see if your parsley needs updating during the course of WACC!

compile

The compile script can be edited to change the frontend interface to your WACC compiler. You are free to change the language used in this script, but do not change its name.

Makefile

Your Makefile should be edited so that running 'make' in the root directory builds your WACC compiler. Currently running 'make' will call the sbt compile and then sbt assembly commands, which will build a wacc-42-compiler.jar in the root directory of the project.
