If any operand for an addition is not a number (nor a string coercible to a number), Lua will try to call a metamethod. First, Lua will check the first operand (even if it is valid). If that operand does not define a metamethod for __addú, then Lua will check the second operand. If Lua can find a metamethod, it calls the metamethod with the two operands as arguments, and the result of the call (adjusted to one value) is the result of the operation. Otherwise, it raises an error.hslua-objectorientationthe subtraction (-9) operation. Behavior similar to the addition operation.hslua-objectorientationthe multiplication (*9) operation.

Behavior similar to the addition operation.hslua-objectorientationthe floor division (//9) operation. Behavior similar to the addition operation. hslua-objectorientationthe bitwise AND (&¸) operation. Behavior similar to the addition operation, except that Lua will try a metamethod if any operand is neither an integer nor a value coercible to an integer (see §3.4.3). hslua-objectorientationthe bitwise OR (|<) operation. Behavior similar to the bitwise AND operation. hslua-objectorientation!the bitwise exclusive OR (binary ~<) operation. Behavior similar to the bitwise AND operation. hslua-objectorientationthe bitwise NOT (unary ~<) operation. Behavior similar to the bitwise AND operation. hslua-objectorientationthe bitwise left shift (<<<) operation. Behavior similar to the bitwise AND operation.hslua-objectorientationthe bitwise right shift (>><) operation. Behavior similar to the bitwise AND operation.hslua-objectorientationthe concatenation (..º) operation. Behavior similar to the addition operation, except that Lua will try a metamethod if any operand is neither a string nor a number (which is always coercible to a string).hslua-objectorientation the length (#ø) operation. If the object is not a string, Lua will try its metamethod. If there is a metamethod, Lua calls it with the object as argument, and the result of the call (always adjusted to one value) is the result of the operation. If there is no metamethod but the object is a table, then Lua uses the table length operation (see §3.4.7). Otherwise, Lua raises an error.hslua-objectorientation the equal (==) operation. Behavior similar to the addition operation, except that Lua will try a metamethod only when the values being compared are either both tables or both full userdata and they are not primitively equal. The result of the call is always converted to a boolean.hslua-objectorientationthe less than (<ê) operation. Behavior similar to the addition operation, except that Lua will try a metamethod only when the values being compared are neither both numbers nor both strings. The result of the call is always converted to a boolean.hslua-objectorientationthe less equal (<=ø) operation. Unlike other operations, the less-equal operation can use two different events. First, Lua looks for the __leû metamethod in both operands, like in the less than operation. If it cannot find such a metamethod, then it will try the __ltœ metamethod, assuming that a <= b is equivalent to not (b < a). As with the other comparison operators, the result is always a boolean. (This use of the __ltÛ event can be removed in future versions; it is also slower than a real __le metamethod.)hslua-objectorientationThe indexing access operation  table[key]û. This event happens when table is not a table or when key is not present in table. The metamethod is looked up in table.hslua-objectorientationThe indexing assignment table[key] = value’. Like the index event, this event happens when table is not a table or when key is not present in table. The metamethod is looked up in table.hslua-objectorientationThe call operation  func(args). This event happens when Lua tries to call a non-function value (that is, func is not a function). The metamethod is looked up in func. If present, the metamethod is called with func as its first argument, followed by the arguments of the original call (args). All results of the call are the result of the operation. (This is the only metamethod that allows multiple results.)hslua-objectorientationÄThe operation used to create a string representation of the object.hslua-objectorientation>the operation of iterating over the object's key-value pairs.hslua-objectorientation;a custom operation, with the metamethod name as parameter.hslua-objectorientation;Returns the metamethod name used to control this operation.  © 2021 Albert KrewinkelMIT,Albert Krewinkel None Ùàì!<hslua-objectorientationÑA property or method which may be available in some instances but not in others.!hslua-objectorientation-A type member, either a method or a variable."hslua-objectorientation5Index types allowed in aliases (strings and integers)%hslua-objectorientation-A read- and writable property on a UD object.(hslua-objectorientationäA userdata type, capturing the behavior of Lua objects that wrap Haskell values.
