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

// 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
• Added Scoped print statements and scoped variables;

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:

• 

6. 5/9/24

int main(){  
 int k =  100 * 100 / 5;
 print(k); 
 return 100 * 100;
}     

main();

print(main())

• 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++
