Update 0.1.12 (10.02.2024)

• Temporarily removed unstable operators +:, -:, *:, /:.
• Interpreter split into parts for easier management. Code simplified using patterns.
• Parser structure changed. Pointer tracking during code reading implemented. Parser errors now indicate error location.

print(1 + );
Expected expression at line 1 column 9

• Keyword print now requires parentheses.

print(E * PI);

Update 0.1.10 (04.12.2023)

• Added operators +:, -:, *:, /:.

data A;
A +: 3;
A : A + 3;

• Optimized token parsing.

Update 0.1.9 (29.11.2023)

• Added the keyword null. To use a missing value, it's necessary to explicitly use null. The absence of a value is no longer automatically considered as null.

data A : null;

• Improved recognition of semicolons.
• Now the initial variables E and Pi are considered non-writable. Their values cannot be changed.
• Improved adaptability and interpretation of variables.

print(data A : 5);

• Fixed a bug where it was possible to initialize a variable with itself.

Update 0.1.7 (28.11.2023)

• Now you can execute code with multiple instructions.

data A : 1;
data B : 2;
print(A);
print(B);

• Added the ability to work with signed numbers. For example: +2, -4.

print(7 + -4);

• Improved language adaptability. Now, the absence of a value anywhere will be interpreted as null;

data A : ();
print(A);

• Changed syntax. Now it's mandatory to put a semicolon after each instruction.

Update 0.1.5 (27.11.2023)

• Optimized parsing of code in brackets.
• Improved error descriptions.
• Added the ability to put a semicolon at the end of a line. It can also be omitted.
• Added the ability to declare variables, initialize them, and change their values.
• Now, only data in the print() key block will be output to the console.
