[Ethereum] How to store Remix Ethereum file

icoremixsolidity

I'm using remix ether to make a smart contract

However, I have no idea how to store information about contract.

If I turn off a computer or want to connect with other things, do i have to rewrite contract codes and deploy it?

There's other way how to save these things with .sol file with my computer?

As you know, If I deploy a contract there's menu on the right side at the conner. Here

BUT NOW i missed everything with turn off the browser. please let me know to store it

You can not save files in Remix, from what I know (they are saved in browser history, but when you clean it, you will lose it), so the simplest solution would be to copy the content of your file to the text file on your computer and save it. Then after you open browser again simply copy content of that file it to Remix. If you really don't want to lose that file just send it to your own email or smth, or store it on github.

Remix runs very fast so deploying it again to local network or JVM Enviroment is not an issue.

If you deploy your contracts to some public network (main, Kovan, Ropsten, Rinkeby) you need to save somewhere the address of that deployed contract so later you can provide that address in Remix to that field "Load contract from address" to interact with it again.

[Ethereum] Compile contracts that call each other

What you need to do is to define the interface of the SubjectContract contract so that the Master contract can compile.

Here is your Master contract with the SubjectContract interface, along with a few minor changes:

pragma solidity ^0.4.2;

contract SubjectContract {
    function increaseCount() returns (uint newCount);
}

contract Master {
    bool public isActive=false;
    uint public num=0;

    function changeState() returns (bool newState) {
        isActive = !isActive;
        newState = isActive;
    }

    function increaseSubjectCount(address subjectAddr) returns (uint newCount) {
        SubjectContract subjectContract = SubjectContract(subjectAddr);
        newCount = subjectContract.increaseCount();
    }
}

Separately you will have to deploy the following SubjectContract with a few minor changes:

pragma solidity ^0.4.2;

contract SubjectContract {
    uint public count = 0;

    function increaseCount() returns (uint newCount) {
        count ++;
        newCount = count;
    }
}

[Ethereum] Ganache (UI) save blockchain

You should use Ganache GUI's 'Workspace' feature. Workspace stores the current state of the chain even after restarting ganache or even the system.

To create a new workspace:

Open up Ganache GUI.
Click on 'New Workspace'.
Enter the Workspace's name and configure settings as per your needs.
Click 'Save Workspace'.
The next time you open up Ganache GUI, select your required workspace from the list.

Your blockchain's state would remain intact.
