Interpreter for a custom scripting language, similar to JS

Demo

You can peek into the supported functionality in this short REPL session.

This is a CMake based project, so you can install CMake and do the following steps.

Create a build folder in the repo root
Change directory into this build
Open a terminal and type cmake .. -G"Your generator". There are many types of generators. For windows, if you have Visual studio installed, you can use a windows generator which will generate a VS solution.
Compile the actual program and run.

For windows, if you are working under VS, you can use the IDE to run the project.
For linux, after the cmake command, you have to run make and run the binary executable.

When the process is terminated with Ctrl + C, the program crashes. When adding Windows.h to handle the Ctrl+C, the project goes wild.
It would be good to warn users if they input a floating point number which overflows the supported precision in our language. For this, we have to introduce a BigDecimal type of object.
The primary grammar rule is trying and failing to parse a semicolon at the end of expression. It should not try to parse it, it should stop.

LoxValue is copied a lot while storing and retrieving from Environment storage. Let's improve that.

Never ignore the warnings from the compiler. Really odd linking errors could happen and some compilers are more strict than others.
In visual studio compiler, when you have reference to an object fields in classes, you must import the header files of these classes. Forward declarations won't work for fields.
