Bs parser

See https://www.youtube.com/watch?v=vcFBwt1nu2U&t=3178s

To start

1. Clone the repo
2. Open in Intellij
3. (You may need to link the dependencies in the lib directory)
4. The main is in src/Main.java
5. Change the code in YOUR_BS_PROGRAM to make some BS!
6. (Sorry if some error messages are in french, this project is using a modified version of a compiler I created for my other project, AliveScript: https://github.com/ALIVEcode/ALIVEcode/tree/master/Interpreteur)

"Features":

supported features are marked as done

1. All variable names must start with €

2. Functions definition and function call

3. echo to print

4. support for numerical data types

5. Code blocks are defined by indentation

   1. 1 level of indentation: 2 spaces
   2. 4 spaces -> 1 tab
      ex: 3 levels of indentation = 1 tab + 2 spaces

6. Odd number of spaces and tab (combined) are comments

7. Multiline coments start with 1 tab + 1 space and end with 1 space and 1 tab

8. Has null

9. if statement doesn't exit, we use unless statement instead

   • value unless not_condition

10. The unless statement ends with a greek question mark ; (which is not a semi-colon)

11. There's only one exception, and it is HALT_AND_CATCH_FIRE (yes, it is a reserved keyword)

12. Inference equality (like javascript)

    • 0 = '0' is false
    • 0 == '' is true
    • 0 == '0' is true
    • 0 == 'Zero' is true
    • 22/7 == 🥧 is true
    • undefined !=! null is true

13. strict equality

    • If you wish for strict inequality, put a bang! after the equal, cause it is an important check!
    • ex: 1 != '1' is false but 1 !=! '1' is true
    • If you wish for strict equality, inverse the result of the strict inequality with a band ! before it!
    • ex: 1 == '1' is true but 1 !!=! '1' is false

14. Strings (partially implemented. For now, only one type and it is utf-8)

    • 'Hello' // ASCII
    • ''Hello'' // ANSI
    • "Hello" // DBSC
    • ""Hello"" // EBCDIC
    • «Hello» // UTF-256
    • ««Hello ${name}»» // UTF-256 + interpolation

15. Arrays

    • Arrays indices start at -1 and go down
