SBU compiler project

in spring 99 semester, we designed a compiler for compiler design course by Dr Jaberi pour in Shahid Beheshti university

language name is Roulang (Rouzbeh + language!)

rules & limitations

• use cup as scanner generator
• use PGEN for parser generation (written by our great friends)
• create Java byte-code (class file) with ASM library
• other aspects of projects are in phase1L syntax highlighter, phase2: parser generation, phase3 : rest of compiler files

team members

• Mehrshad Sa'adatiNia (github link)
• Roozbeh Sharifnasab (github link)

how to use

• install maven, Java 13+

• open terminal in this folder and run:

  mvn clean package 

• then you have a complete jar file (target/RoulangCompiler-1.0-jar-with-dependencies.jar)
• to use compiler:

java -jar ./target/*s.jar path/to/in.rou /path/to/out.class

this will create an executable class file out.class from input file in.rou

• to run the class file:

  java out

  and for viewing whats in it:

  javap -p out.class
  javap -v out.class #verbose

notes

• in first try to run maven, it will download dependencies, don't worry.

• if there was problem in tests, you can skip tests (not recommended)

mvn clean package -Dmaven.test.skip=true

and then use the jar file

• parser graph in PGS format is in parser folder, after editing that, create npt file in same directory named table.npt, it will copied to folders with ./updateTable.sh.

• this project is not well debugged, don't use it in production :D

additions

• you can syntax highlight the language with vim, when you opened file, run: :source syntax.vim

• you can import other rou files as well
