This article introduces the "solidity online editor Remix Chinese version of how to configure" related knowledge, in the actual case operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

Remix is the official open source Solidity online integrated development environment in Etaifang, which can be used to complete the online development, online compilation, online testing, online deployment, online debugging and online interaction of ethernet intelligent contracts in the web page, which is very suitable for the learning and rapid prototype development of Solidity intelligent contracts.

Solidity IDE Remix has a left, middle and right column layout, the left panel is the Remix file manager, the middle is the file editor, and the right is the development tools panel:

1. Solidity IDE Remix File Manager

The file manager in the left panel of Remix is used to list the files saved in the local storage of the browser. It is divided into two directories: browser and config. When you visit Remix for the first time, there are two preset codes in the browser directory: ballot.sol contract and the corresponding unit test file ballot_test.sol. Click the file name to view and edit the code in the middle file editor:

The toolbar at the top of the Remix File Manager provides quick functions such as creating new files, uploading local files, and publishing gist. You can move your mouse over the appropriate icon and pause, and then view the floating prompts for the function.

In order to learn the following functions, you can click + in the upper left corner to create a new solidity contract file, and in the pop-up dialog box, name the file hello.sol:

Click the [ok] button, you can see in the left panel of file management in which the hello.sol file name appears in the browser directory, while in the middle area of the file editor automatically opened the newly created file waiting for editing, it is still empty, we will write simple Solidity code below.

2. Solidity IDE Remix editor and terminal

The middle area of Solidity IDE Remix is the upper and lower layout, which provides file editing function and terminal access function respectively.

2.1 Remix File Editor

The file editor above the middle area of Solidity IDE Remix supports opening multiple files at the same time, and the file name of the currently active file is shown in bold:

The arrows on the left and right sides of the top of the Remix file editor are used to switch between the display and hiding of the left and right panels; the + and-in the upper left corner are used to enlarge or reduce the text font size in the editor, respectively.

Now let's activate the hello.sol file and enter a simple contract code:

Pragma solidity ^ 0.5.1 X contract Hello {function echo (string memory text) public pure returns (string memory) {return text;}}

Basically this is the simplest ethernet contract, which has only one echo () method, which returns the input string as it is.

2.2 Remix terminal

Below the middle area of the Solidity IDE Remix is the terminal, and you can enter the JavaScript command to interact with the Remix IDE or block chain node:

The Remix terminal has built-in web3.js 1.0.0, ether.js, swarmgy, and the currently loaded Solidity compiler, so you can use the familiar web3 API in the terminal to interact with the currently connected block chain node.

The Remix terminal also has a built-in remix object that can be used to manipulate Solidity Remix IDE scripted, such as loading the gist of a specified url or executing the currently displayed code. Scroll the terminal display up to the start position and you can see a description of the common methods of the remix object.

Another function of the Remix terminal is to display the running results of contract execution or static analysis. For example, when you deploy a contract or execute a contract method, you will see its execution information on the terminal:

Click the drop-down icon on the right side of the information line to view the details of the information; click the [debug] button to open the debugging page in the right panel to debug the contract step or breakpoint.

The toolbar at the top of the Remix terminal provides functions such as switching terminal display status, cleaning terminal output, displaying the volume of pending transactions, selecting the range of monitoring transactions, and searching for historical transactions.

3. Solidity IDE Remix function panel

On the right side of the Solidity IDE Remix is the function panel, which provides compilation, running, static analysis, testing, debugging, setup, and technical support functions in the form of options pages.

3.1 compile options page

On the compilation options page, you can click the drop-down box to switch the current version of the Solidity compiler to use:

Then click the start compilation button, and the currently selected code file in the Remix file editor, such as our hello.sol file, will be compiled. After the compilation is complete, if there are no compilation errors, you can see that the contract name Hello appears in the contract drop-down box on the compilation option page:

You can click the "swarm" button to upload the compiled contract to the Swarm network, or click the "details" button to view the details of the compilation result, or click the "ABI" or "bytecode" button to copy the ABI and bytecode of the contract to the system clipboard for use in other programs.

3.2 run the options page

On the run options page, you can deploy the compiled contract or execute the method of the deployed contract:

The node environment option provides three choices: JS virtual machine, injecting Web3 objects, or using the web3 provider.

The JS virtual machine is a JS version of the etherfang virtual machine implementation, which runs in your browser, so you don't need to think about node configuration or worry about losing ethernet coins, which is best for learning and rapid prototyping verification.

If your browser has the Metamask plug-in installed, or if you use an ethernet compatible browser such as Mist, you can also choose the second environment: using injected Web3 objects.

If you have your own node, you can choose the third option to use the web3 provider to connect Remix to your node, but if the node you want to connect to is connected to the Ethernet Fong main network, note that there is a cost for each transaction!

If you have a previously compiled contract, you can see the name of the contract on the run option page, such as our Hello. Click the "deploy" button to deploy this contract to our selected node environment:

Now we can see that our contract has already appeared in the deployed contract area. Click on this contract example to see that the echo method we defined for the Hello contract is automatically displayed:

Enter the method parameters, such as "helloooooooooooooo", in the input box after the method name, and then click the method name to execute the contract method:

As you can see, the return value is indeed the same as the parameters we entered, and we have achieved our predetermined goal!

3.3 other options Page

The Solidity Remix integrated development environment still has a lot of features to study, which is up to you. We will only give a brief introduction to the other option pages:

The Analysis options page provides options for static analysis of Solidity contract codes.

The Test options page provides unit testing capabilities, and you can generate a test file or execute a set of tests.

The debugger options page can step through the execution of the contract, view the contract status or local variables, and so on.

Setting options provide some of Solidity Remix IDE's own parameter adjustment capabilities, such as setting editor text auto-wrapping, enabling plug-ins, setting gist access tokens, or switching Remix IDE's skin theme-there are currently only three: light, dark, and clean.
