Abstract-VM is the first C++ 42 school project. The objective is to practice in C++ and Object-Oriented Programming by coding a simple instruction executer & a lexer/parser.

In order to compile and use this program, you need a UNIX operating system, the clang++ compiler, the Bison and Flex softwares, and the Make software. All you need to do is to use the command make in the root folder of the project.

Here is a small description of the program, as describe in the project subject:

AbstractVM is a machine that uses a stack to compute simple arithmetic expressions.
These arithmetic expressions are provided to the machine as basic assembly programs.

More informations about the assembly language used in the project can be found in the project subject.

• Complete Lexer / Parser impementation using yacc and flex as a parser generator, in order to parse a pseudo assembly language.
• Use of C++1z standard for a better use of C++ meta-programming. (constexpr operations, templates, ...)
• Pseudo assembly language parsing and execution using a list to store instructions, and a stack to store and compute the data.

In a command line interface, use the command ./abstract_vm to print the usage. In order to execute a set of instructions, you either need to give the program a file with the instructions, or write them in the standard input (by giving stdin or - to the program).
