@ -6811,6 +6811,23 @@ an itemstring, a table or `nil`.
* `peek_item(n)`: returns taken `ItemStack`
* Copy (don't remove) up to `n` items from this stack
* `n`: number, default: `1`
* `equals(other)`:
* returns `true` if this stack is identical to `other`.
* Note: `stack1:to_string() == stack2:to_string()` is not reliable,
as stack metadata can be serialized in arbitrary order.
* Note: if `other` is an itemstring or table representation of an
ItemStack, this will always return false, even if it is
"equivalent".
### Operators
* `stack1 == stack2`:
* Returns whether `stack1` and `stack2` are identical.
* Note: `stack1:to_string() == stack2:to_string()` is not reliable,
as stack metadata can be serialized in arbitrary order.
* Note: if `stack2` is an itemstring or table representation of an
ItemStack, this will always return false, even if it is
"equivalent".
