# Cobalt BASIC
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
## Files
---
### main.py
- Contains the shell for running programs in my programming language
- imports basic.py
### 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
### string_with_arrows.py
- Contains a single method called `string_with_arrows`, for inserting `^` characters where an error appears in the code
### Token.py

## Credits
The base of this code was written while following this [tutorial series](https://www.youtube.com/playlist?list=PLZQftyCk7_SdoVexSmwy_tBgs7P0b97yD) 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.
