Cylium Error and Warning Codes Documentation

Language version: 0.1.1

This document lists all standard error and warning codes in Cylium, with explanations and context.
Each code has a unique identifier and a descriptive message.

Note:
- Codes starting with A are errors. They stop program execution.
- Codes starting with C are warnings. They indicate non-critical issues but do not stop execution.

Errors (Axx)

Syntax and Operator Errors

Code	Message	Description
A01	Expected parameters for operator.	An operator was used without required arguments. Provide all necessary parameters.
A02	Cannot convert value to numeric type.	Failed to convert a value to a number. Check value type and formatting.
A03	Requested variable does not exist.	Attempted to access a variable that has not been declared.
A04	Expected assignment operator ‘=’ after variable name.	The variable declaration is missing the `=` operator.
A05	Invalid variable name.	The variable name does not follow Cylium naming rules (ASCII, not starting with a number, length <= 256).
A06	Unknown operator.	Used an operator that does not exist in Cylium.

Type and Constant Errors

Code	Message	Description
A07	Cannot modify a constant variable.	Tried to change a variable declared as `const`. Constants are immutable.
A08	Unknown data type.	Attempted to convert or declare a type that does not exist.
A09	This operator can only be used with vectors.	The operator requires a vector type, but another type was provided.

Control Flow and Brackets

Code	Message	Description
A10	Unclosed bracket.	A `(`, `[`, or `{` was not properly closed.
A11	Requested label does not exist.	`goto` or a jump statement referred to a label that is missing.
A12	Expected ‘then’ keyword after condition.	After `if` or `else if`, Cylium requires the `then` keyword.
A13	Invalid condition.	The condition expression cannot be parsed or is invalid.

Expression and Type Checking

Code	Message	Description
A14	Expression types do not match.	Tried to operate on incompatible types, e.g., adding a string to a number.
A15	Invalid expression.	The expression syntax is incorrect or cannot be evaluated.
A16	Invalid type for arithmetic operation.	An arithmetic operation was applied to an unsupported type.
A17	Invalid array index.	Tried to access a vector element with an invalid index (negative or out-of-bounds).

Warnings (Cxx)

Code	Message	Description
C01	Variable is already of the target type.	Attempted to cast a variable to a type it already has. Redundant but does not stop execution.

Usage Notes

Errors (Axx) stop program execution and must be fixed before the code can run correctly.
Warnings (Cxx) do not stop execution, but they indicate potential issues or redundant operations.
Properly handling errors and paying attention to warnings improves code reliability and maintainability.

This system allows developers to quickly distinguish between critical errors that stop execution and non-critical warnings that can be safely ignored or optimized.
Properly handling errors and paying attention to warnings improves code reliability and maintainability.
