Important: If you are taking this course then I suggest you to try to write the assembler yourself first, it is not very easy and not very tough too. At least not impossible, because I did it 😘

Get Started with the project

Directory Structure

    .
    |_include      # Contains headers
    |_src          # Contains Source Code and Main
    |_Test-Files   # Example HACK VM Files

Clone this repo

    git clone https://github.com/avinal/The-VM-to-HACK-Translator.git

Build and run, provide only HACK VM Language file. Don't confuse with .vm extesion.
```
    cd The-VM-to-HACK-Translator
    make
    ./VMTranslator file.vm
```
Start over after modification
```
    make clean
```

Tips

In case you want to modify this project, you can use Boost C++ Libraries, they can simplify many tasks needed by this project.

Some Words

This was a nice project and taugh me many things. Given below are some miraculous code snippets that proved to be really useful and are well researched. Hope you will find them useful.

Trim spaces, comments, carrige returns, newline, tab and verticle tabs:

    inline std::string trim(std::string str)
    {
        if (str.find('/') != std::string::npos) // comments
        {
            str.erase(str.find('/'));
        }
        str.erase(0, str.find_first_not_of(" \r\t\v\n")); //prefixing
        str.erase(str.find_last_not_of(" \r\t\v\n") + 1); //surfixing}
        return str;
    }

Tokenize a string using C++ with respect to a delimiter, space by defalt (string split):

    #include <sstream>
    #include <vector>
    std::vector<std::string> split(std::string str, char delimiter = ' ')
    {
        std::vector<std::string> tokens;
        std::stringstream tokenizer(str);
        std::string intermediate;
        while (std::getline(tokenizer, intermediate, delimiter))
        {
            tokens.push_back(intermediate);
        }
        return tokens;
    }
