Cobalt BASIC is a simple, dynamically typed, interpreted programming language with syntax inspired by python and javascript with an aim for readability and understandablility. It is not the fastest langauge ever because it is interpreted by python, but it will get the job done for simple tasks

• Contains the shell for running programs in my programming language
• imports basic.py

• Contains all the code the actual programming language, including the lexer, parser, and interpreter
• imports string_with_arrows.py, Token.py, Nodes.py, Lexer.py, Errors.py, and Parser.py

• Contains a single method called string_with_arrows, for inserting ^ characters where an error appears in the code

• Contains the Token class and all token type constants used in the language

• Contains all global variable for the interpreter

Contains all these classes

• Symbol Table
• Context
• Value and subclass
• RunTime Result
• Interpreter

• Contains the Lexer

Contians all these classes

• Parse Result
• Parser

• Contains all Node classes

• Contains the position class

• Contains the Error class and all subclasses

The base of this code was written while following this tutorial series on youtube. I have added some of my own features and syntax. I plan to go beyond this tutorial series and add even more features as I learn more about this topic.
