6502(a) Compiler

Compiler written in Java.

BNF notation of our language, https://labouseur.com/courses/compilers/grammar.pdf

Setup

• Navigate to /src

• Compile all files:

  • If using Linux/Unix, chmod +x ./findAndCompileAllJavaFiles.sh

  • ./findAndCompileAllJavaFiles.sh

Usage

Use the Java "Compiler" class, along with an input file and optional flags, to compile a source program

To use the program to compile source code found within "test.txt" or "easyprogram":

java Compiler test.txt java Compiler easyprogram

There are tests available within /input

A good test for semantic-analysis is semantic-analysis-mega-test

For example, to use the program to compile source code found within "test.txt" or "easyprogram":

java Compiler test.txt java Compiler easyprogram

This compiler executes in verbose mode by default. To run it in terse mode, append the '-t' flag:

java Compiler easyprogram -t

For evaluation purposes, it is HIGHLY ADVISABLE that you choose to run the compiler in terse mode.

Alternatively, if you want even-more verbose output, try using debug mode using '-d' flag. (Note: Not fully implemented. Currently only offers slightly more verbose output.)

Minimum Requirements:

• Java 21
