csc435-compiler-construction

Compiler written in Java for Unnamed Language (UL), a language that looks like C but with much less functionality.

Dev setup

CLASSPATH environment variable used in this project for the following purposes:

• finding compiled classes in the classes/ dir (IMPORTANT)
• finding antlr.jar
• finding codegen/jasmin stuff

Make sure to add these to your class path. I added the following to my ~/.zshrc on Macbook and ~/.bashrc on Linux lab machine:

# ~/.zshrc
source /Users/julianrocha/code/csc435-compiler-construction/setclasspath_macbook
# ~/.bashrc
source /home/julianrocha/Desktop/csc435-compiler-construction/setclasspath_linuxbox

Building, Testing, and Running

To build the compiler, run:

$ make

To deleted compiled executables, run:

$ make clean

To verify and type check the test cases without compiling them to bytecode and running them, run:

make verify

To build and run tests, run:

$ make test

To compile a sample UL program, my_program.ul, make sure the classes/ folder have been added to classpath then, build the compiler and then run:

$ java Compiler my_program.ul

This will ouput an .ir file in the same directory that the command was run from.
