# VSCRIPT

What is vscript?

- A staticaly typed language built ontop of java

- A project aimed to improve skillset

- A simple language

Beginner dev?

1. What will i gain reading through the code?

 - You will be able to understand how lexers work - proper usage of Abstract Syntax Tree's (AST);

 - You will be able to understand 

    - string manipulation 

    - Arrays

    - Loops

    - Common lexing lookaheads char indexing;

    - ArrayLists

    - Type checking / string parsing

    - Lexical logic

# TODO LOG

-  Improve printing values , currently we cannot add more than one operator assignment [Done];

-  Allow function calls  / working out a scope system [Done]l

-  Refacotoring - organizing different parts of the lexer / some optimizations  

-  Error handling

# Changelog

1. 5/2/24 

 - Added print statements 

 - Parsed integer variables by their operator type; 

 - Fixed issue with whitespace within left hand assignments;  

 - Fixed improper math calculation

2. 5/3/24 

 - Better code management / error handling 

 - Added the ability to chain operators

 - Added ability to use \n within strings in print statements - aswell as adding two strings together

3. 5/6/24  

 - Fixed calculation issues with division

 - Started working on functions

 ```v

 // will soon work

 int main(a , b){

    return a + b

 }

 ```

 4. 5/7/24

  - Still working on getting functions working!

 5. 5/8/24

  - Functions are shown to work

  ![Functions Working](screenshots/image.png)

  - Added Scoped print statements and scoped variables;

```v

int main(a, b){ 

  int x = 100; // this should be scoped

  print(x); // this will also be scoped to the function

  return  a + b;

}     

print(x); // x should not be working here

``` 

Error: 

  - ![unsgined print](screenshots/image3.png)

6. 5/9/24

```v

int main(){  

 int k =  100 * 100 / 5;

 print(k); 

 return 100 * 100;

}     

main();

print(main())

```

 ![alt text](screenshots/image4.png)

 - You can now call functions aswell as print returned values!

 - Fixed issue where printing a number without an opperand threw an error aswell as printing strings without opperands

 - Fixed issue where printing strings by themselves or numbers by themselves threw an indexing error

 - Added ability to print strings + variables or parameters

 - Added ability to print parameters

# Road Map!

1. Scoped (Global|Private) - this is a must have currently int can be called within any scope - it would be effective if variables are bound to the parent container and cannot be accessed outside of it!  (Currently Working On)

2. Functions (Currently Working On)

 - Being able to invoke functions within itself but also outside 

3. If Statements - the embodiment of any logic 

4. Imports and Exports;

5. Switch cases - performantttt

6. Rewrite a subset in c++
