Cylium Error and Warning Codes Documentation

Language version: 0.4.1

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)

Code Message Description
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).
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.
A10 Unclosed bracket. A (, [, or { was not properly closed.
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).
A18 This operator can only be used with strings. The operator requires a string type, but another type was provided.
A19 Cannot convert value to vector. Failed to convert a vector to a number. Check value type and formatting.
A20 Statements are only allowed inside procedures Tried to use a statement outside of any procedure.
A21 Unclosed string. A " was not properly closed.
A22 Entry point procedure main not found. The program does not contain a main procedure, which is required as the entry point.
A24 Requested procedure does not exist. Attempted to call a procedure that has not been declared.
A26 Expected code for exit. exit statement is missing a required return code or expression.
A27 Arguments count do not match. Called a procedure with the wrong number of arguments.
A28 Cannot delete a constant variable. Attempted to delete a variable declared as const.
A29 Expected variable name to delete. Attempted to delete a variable that has not been declared or already has been deleted.
A30 This operator can only be used with vectors. The operator requires a vector type, but another type was provided.

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.
C02 Failed to read input. The program could not read input from the user or source. Check input source and format.

Usage Notes

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.
