lity solidity language

lity's Introduction

Lity is an open-source language enhanced from Solidity. With new grammar extension, it is highly optimized for enterprise and easy to use for financial industry developers. The flexible interface and unlimited built-in functions can reduce gas cost and accelerate executing time. You can now encrypt large-sized data in the blink of an eye without running out of gas anymore.

Getting Started

To get started you can find an introduction to the language in the Lity documentation.

The changelog for this project can be found here.

I tried to attach to the public rpc service that CMT provided: rpc.cybermiles.io:8545 but the same error occur.

There is another issue about attaching to this Travis Console, see here: Issue #19

Any idea how can i fix this ? Thanks.

Couldn`t find package libboost-all-dev .

Found a problem when installing Lity.

Error: invalid solidity type!: safeuint

I am getting the following error

> deployedSmartTokenContract.c();
Error: invalid solidity type!: safeuint

If I compile and deploy the the contract C and then call its function c as per the example at https://lity.readthedocs.io/en/latest/safeuint.html#example

pragma solidity ^0.4.22;

contract C{
    function c() public pure returns (safeuint) {
        safeuint a = 0x7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff;
        safeuint b = 0x8fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff;
        return (a*b);
    }
}

Question: Where I can find some docs about `main()` or hello, world?

Where I can find some docs about main() or hello, world?

EVM version check

Should check EVM version parameter when codegen Lity-only instruction set.

Currently, these functions have never been used.

lity/libsolidity/interface/EVMVersion.h

Lines 80 to 83 in 4f90b5f

    
           bool hasENI() const {return *this == lity(); } 
        
           bool hasIsValidator() const {return *this == lity(); } 
        
           bool hasFreeGas() const {return *this == lity(); } 
        
           bool hasRand() const {return *this == lity(); }

I found an error when running the code, how to solve it ? thank you.

code: source ./scripts/install_deps.sh
error:
