Introduction
fi is a statically typed high-level programming language designed to be similar, syntactically, to ECMAScript/Javascript and Solidity. fi compiles directly to valid and well-typed Michelson code, the native smart contract language for the Tezos block chain.
fi allows developers to work in a more familiar coding environment, providing a close experience to object-oriented programming. Here's a really short demonstration of the potential of developing smart contracts with fi:
# King of Tez Contract
# Define a constant for ONEWEEK in seconds
const int ONEWEEK 604800;
# Define an object King
struct King(
timestamp end,
mutez bounty,
address owner);
# Declare a storage variable king of type King (the object we created)
storage King king;
# Entry point for this script
entry contend(){
assert(storage.king.end < NOW || AMOUNT > storage.king.bounty);
let address oldKing = storage.king.owner;
storage.king = new King(add(NOW, ONEWEEK), AMOUNT, SENDER);
transfer(oldKing, AMOUNT);
}
This smart contract reads extremely easy within fi, but accomplishes an extremely advanced set of functions.
You can install our compiler by following instructions from our Github repo - this will allow you to install and use our compiler. You can also use our online compiler tool as well.
The web-based browser/editor will compile your fi to Michelson and typecheck the compiled source code. Furthermore, you can run tests against your Smart Contract to simulate live operations and calls.
