C++ Compiler

Basic C++ Compiler, built for educational purposes

Currently working on the lexical scanner, the first stage of the compiler.

Dependencies

Must be compiled using g++, there is support for mingw32's g++ as long as it is installed in the default directory; otherwise, you may need to play with the makefile to make it find your installation.

Overview of Files

Header Files

TokenType.h

• This contains the possible types of each token, declarations of all of the regular expressions for each type, and a hashmap with pairs of the types and regex values.

Token.h

• This contains the Token class constructors and methods, the behavior is as such:
• A Token is initialy created as a place holder object to manage token function calls, it serves as a temporary object to pass values to new instantiations. When a true token is instantiated, it is given a string of the token content, and a type which is defined in the TokenType.h file.

Source Files

TokenType.cpp

• This contains the actual definitions of the regular expressions and populates the hashmap.

Token.cpp

• This contains a default constructor, the overloaded constructor, a function to wipe the temporary token content, and an operator overload to print token items.

main.cpp

• This is where the tokenizer process is actually implemented, the program takes an input file and will scan each line into a vector, then it will tokenize the input and return the lexemes with their associated types.
