IS521 Activity3: Backdoor

File Description

• ./interpreter/
  • interpreter.c : C source code that reads, translates and executes bytecode which converted by compiler.
• ./login/
  • login.mini : A login program written in Mini Language. This program is generated by my awesome program generateMini.java.
• ./test/
  • test.mini : A test program written in Mini Language, which randomly chooses a donation angel who will buy others coffee.
  • test.md : A description file which explains a test.mini program in detail.
• ./backdoor/ : I copied interpreter.c and then added some code in gets, puts, and eq functions. I tested my backdoor program with my colleague (moonbeam, soomin, daramg, seongil)'s login.mini, and I got all correct result except soomin's one.
• ./compiler/
  • compiler.ml : A compiler written in Ocaml, which convert mini language code into bytecode.
• ./generateMini/
  • generateMini.java : An awesome program written in JAVA, which automatically generates mini source code from the input file. Please refer to the ./generateMini/README.md for details.

What I learned

• I learned how compiler understands source code and converts them into bytecode.
• I learned how interpreter handles and executes bytecode.
• When I made a mini source code program by my hand, I realized that I don't have trust in my eyes and fingers. So, I made a program that automatically generates mini source code from the input file. However, I figured out that coding by my hand would be more faster, unless making a new compiler which supports all possible functions.
• When I made a test program, I tried to make creative one and I'm proud of my result. (뿌듯하다는 뜻 입니다...)
