Egern

The Egern programming language - written for the bachelor project: 'Constructing a Compiler for an Object-Oriented Language' at the University of Southern Denmark.

Created by: Alexander Køllund Nissen, Jacob V. M. Nielsen, Frederik Vogt Bolding.

Dependencies

  • Java
  • GCC

Instructions

The project is built with the Gradle build script gradlew found in the root directory of the project. The compiler may be run by invoking this script with the run argument, i.e. ./gradlew run.

A number of useful scripts can additionally be found in the /src/test/ directory. They are separated into platform specific subdirectories, /src/test/%PLATFORM%. Bash scripts are available in /src/test/linux. All scripts are run from the /src/test/ directory, such as running ./linux/run. Available Bash scripts include:

  • compile can be used to compile a custom file and outputs Assembly
  • run both compiles and runs a custom file
  • test can be used to run a single test from the /src/test/success folder. The result is compared to the corresponding file in /src/test/expected.
  • test_all runs all tests to make sure everything is working! This only runs tests from /src/test/success
  • compilep runs the compiler on a custom file and outputs the source code from the constructed AST. Information from each symbol table is also output
