Programming Exceptions

Programming exceptions are thrown by m, and usually caused by an error in your code or an unexpected user input.

• ExcArrayNotNumber: Operand is an array, not a number.
• ExcBooleanNotNumber: Operand is a boolean, not a number.
• ExcForwardFunction: Function is only forward declared.
• ExcFunctionNotNumber: Operand is a function, not a number.
• ExcIndexOutOfRange: Array index is out of range.
• ExcInterrupted: Interrupted function call.
• ExcInvalidIndexType: Array index is neither number nor string.
• ExcInvalidNumber: Wrong number format.
• ExcInvalidUTF8: Invalid UTF-8 character read.
• ExcModuleBusy: Module is busy with other function.
• ExcNativeNotNumber: Operand is native object, not a number.
• ExcNoSuchClass: Class not loaded.
• ExcNoSuchKey: No array element for key.
• ExcNotArray: Operand is not an array.
• ExcNotAvailable: Function or variable is unavailable.
• ExcNotBoolean: Operand is not a boolean.
• ExcNotComparable: Can only order two numbers or two strings.
• ExcNotFunction: Operand is not a function reference.
• ExcNotNative: Operand is not a native object.
• ExcNotNumber: Operand is not a number.
• ExcNotString: Operand is not a string.
• ExcNotSuchInstance: Not such instance.
• ExcNullNotNumber: Operand is null, not a number.
• ExcNullNotInstance: Operand is null, not an instance.
• ExcStringNotNumber: Operand is a string, not a number.
• ExcStringPosOutOfRange: String position is out of range.
• ExcTooManyGlobals: Too many global variables, split into modules.
• ExcUnknownField: Unknown field referenced by native function.
• ExcUnknownModule: Unknown module referenced by native function.
• ExcValueOutOfRange: Value or parameter is outside valid range.
• ExcWrongNative: Operand has wrong native object type.
• ExcWrongParamCount: Too many or too few function parameters.

Internal Error Exceptions

Internal error exceptions are thrown by m when it detects an internal inconsistency. These exceptions cannot be catched, and are most likely caused by a bug in m or in a native module.

• ErrDisabledFunction: Internal error: interpreting disabled function.
• ErrDuplicateModule: Internal error: duplicate module.
• ErrDuplicateNative: Internal error: duplicate native function.
• ErrEndOfCode: Internal error: falling through end of code.
• ErrInvalidDll: Internal error: DLL did not return module.
• ErrInvalidFrame: Internal error: invalid stack frame contents.
• ErrInvalidFunctionIndex: Loader error: invalid function index.
• ErrInvalidInstruction: Internal error: invalid instruction.
• ErrInvalidModuleIndex: Loader error: invalid module index.
• ErrInvalidStack: Internal error: invalid stack.
• ErrInvalidVariableIndex: Loader error: invalid variable index.
• ErrMissingDll: Internal error: module DLL is missing.
• ErrNativeFunction: Internal error: interpreting native function.
• ErrNoCode: Internal error: interpreting without code.
• ErrNoNativeFunction: Internal error: no native function to add option to.
• ErrNotInstance: Internal error: using non-instance as instance
• ErrRTVersionMismatch: Internal error: runtime version mismatch. Get an up to date version of the runtime or native module.
• ErrStringExtension: Internal error: string extension.
