We present a change in version 1.3.0 of the evaluation process of boolean operators and and or in test expression of the if instruction and expression.

Consider the following if instruction:

if a and b then
 /* */
end

We present an improvement in the way assets data are accessed in version 1.3.0.

Problems​

Until this version, the only way to access an asset data was the field accessor operator of the form A[k].f, where A is the asset collection, k the asset key and f the asset field.

We present a new type of map called iterable_big_map, which has the scalability property of a big_map, and which can be iterated like a basic map.

This feature was suggested by Nomadic Labs. Thank you to Lucas Feli and Charles Delhinger for the algorithm.

Example​

Consider the following declaration of an iterable big map between a nat key and a bytes value:

variable ibm : iterable_big_map<nat, bytes> = []

We present the new instruction emit to emit an event, in a similar an event is emitted in languages like solidity.

This feater was suggested by Nomadic Labs. Thank you to Bruno Bernardo for the event well mechanism.

An event is declared with the event keyword, similarly to a record:

event HighestBidIncreased {
  bidder : address;
  amount : tez
}
