Compiler Project Phase 0

Compiler project built for CS 4386.

Currently we are at phase 0, which simply identifies the tokens.

Build and Execution

Run the basic test with make run. If you want to run the extensive tests, execute make test. Both commands will build the lexer and parsers.

Another test case will run on an actual code file (adv-tests.txt). Use make adv-test to run these advanced tests.

There is one last test case that just has illegal tokens (bad-tests.txt). This file will make the scanner not happy and can be run using make bad-test.

To Run Custom Tests

To run a custom test, simply create a new rule in the Makefile in the following format:

test: all
		$(JAVA) -cp $(CP) LexerTest tests.txt > tests-output.txt
		cat tests.txt
		cat -n tests-output.txt

Replace test with the make command you wish to use, replace tests.txt with the input test file, and tests-output.txt with the file you wish to output text to.
