Youtube truffle extension

By Kingsley Arinze We're excited to announce the release of Truffle for VS Code, an extension that allows newbies and experienced web3 developers to code, debug, and deploy their smart contracts without needing to leave VS Code. Some of its key features include: You can start a new Truffle project from scratch or from a Truffle Box You can deploy your smart contract easily by connecting to your Infura account and fetching all your existing projects with their corresponding networks' RPC endpoints. You can also create new Infura projects from VS Code You can debug a transaction using the native VS Code debugger instead of the command line You can connect to Ganache local blockchain and deploy smart contracts from a user interface without leaving VS Code Instead of performing these tasks via the command line, VS Code users can seamlessly use a single interface, improving the user experience and speeding up the development process. VS Code remains one of the most popular code editors available today. Created by Microsoft, this code editor is available for free on all major Operating Systems and houses a lot of extensions that help simplify workflows. Extensions on VS Code are created by Microsoft or independent teams/developers. The Truffle for VS Code extension was originally started by Microsoft as the Blockchain Development Kit for Ethereum and through the partnership, with Truffle, Microsoft transitioned the management of the extension to the Truffle team. In summary, this extension is designed to help VS Code users build, debug, and deploy smart contracts on the Ethereum blockchain using the Truffle suite of tools. Installing the VS Code Extension for Truffle¶ The easiest way to get started is by browsing the VS Code built-in marketplace tab. Search for Truffle for VS Code, and click the install button. An alternative way is to visit the VS Code marketplace and install directly from the website. Upon installation, you will get a prompt to download some dependencies or upgrade the versions you already have to newer versions. The Truffle for VS Code extension surfaces in the following areas in VS Code, each with different sets of commands: The VS Code command palette (SHIFT + CMD + P): here, you can perform tasks such as: Creating a new Solidity project Creating and connecting to a new network Starting and stopping Ganache local blockchain Debugging transactions using VS Code native debugger The VS Code

Context menu (Right-click on a .sol file): here, you can perform tasks such as: Adding a new contract from OpenZeppelin Building your contracts Deploying your contracts to your network of choice The VS Code Tree view (Under the Explorer tab): here, you can create and connect to an Infura or Ganache network without leaving the VS Code application Try these features!¶ 1. Preview version of the Truffle Debugger with native VS Code support¶ The Truffle Debugger uses the native VS Code debugging feature, allowing VS Code users to debug their transactions in the ways they are familiar with: visually stepping through the code to understand how it behaves. To start debugging a transaction using the extension, open the command palette with SHIFT + CMD + P and select "Truffle: Debug Transaction". The extension would list all the previously run transactions in chronological order. Clicking on any transaction starts the debugging process, and you can step through to gain more insight into that transaction. 2. Sign in to your Infura account and deploy contracts without setting up a new network in your Truffle config file¶ With this extension, you no longer need to leave the VS Code application to create a new Infura project or deploy to an existing Infura project. Instead, you can sign in to your Infura account from VS Code by simply clicking a button. This would list all your Infura projects and their corresponding network RPC endpoints. With Infura set up, you can right-click on a contract, select the "Deploy contracts" option, and pick a Project/Network combination to deploy your contract to. The extension outputs information about your contract deployments to the Output tab on the VS Code command line. You also need to ensure that its reading outputs from "Truffle for VS Code". 3. Connect to Ganache local blockchain and deploy contracts from a user interface without leaving VS Code¶ The VS Code extension allows you to start, stop, and deploy smart contracts to the Ganache local blockchain without leaving the VS Code application. Simply create a new Ganache network under the "Truffle Networks" tab, and right-click to see the start/stop menu. With Ganache running, you can right-click on your smart contract file and select the "Deploy Contracts" option. This would list all the available networks, including those from your truffle-config file and networks you created using the extension (Infura and Ganache). Next, select the Ganache

Written by Emily Lin Last updated 1/05/2023 Overview¶ Our full-stack NFT rental marketplace is done! We created a rentable NFT, wrote a rental marketplace smart contract, and built a frontend to tie it all together. In this guide, we'll be adding some details to improve the user experience: using Push to send decentralized notifications whenever a user's rental has expired. Additionally, we'll be using ganache forking to test our contracts and interact with the Push contracts locally before deploying to an actual testnet or mainnet. Watch the livestream on YouTube for a more in-depth walkthrough and to hear from core dev, Fabio, about how Push is changing up Web3 communication! The completed code lives here. NOTE: We are only interacting with the smart contracts, so you can ignore the client folder. Download System Requirements¶ You'll need to install: Node.js, v14 or higher truffle ganache CLI Create an Infura account and project¶ To connect your DApp to Ethereum mainnet and testnets, you'll need an Infura account. Sign up for an account here. Once you're signed in, create a project! Let's call it rentable-nft-marketplace, and select Web3 API from the dropdown. To interact with your DApp in the browser, you'll need a MetaMask wallet. You can download it and create one here. Download VS Code¶ Feel free to use whatever IDE you want, but we highly recommend using VS Code! You can run through most of this tutorial using the Truffle extension to create, build, and deploy your smart contracts, all without using the CLI! You can read more about it here. Get Some Test Eth¶ In order to deploy to the public testnets, you'll need some test Eth to cover your gas fees! Paradigm has a great MultiFaucet that deposits funds across 8 different networks all at once. Set Up Your Project¶ We'll be starting with the marketplace contracts we wrote in episode 4. Go ahead and clone the main project here. Since we're only interacting with the smart contracts in this tutorial, we'll just go to the truffle folder and install our dependencies. cd unleashed_nft_rental_marketplace/trufflenpm i Create a Channel in Push¶ In order to send notifications, we need to create a channel for users to subscribe to. To create a channel, see the Push docs here. In this guide, we are only building on Ethereum, so ignore any instructions for multi-chain channels. Additionally, we are deploying on Goerli and NOT

Truffle includes an integrated debugger so that you can debug transactions made against your contracts. This debugger looks and feels like existing command line debuggers available for traditional development environments. Overview¶ New in Truffle v5.1: truffle test --debug. Set breakpoints in your JavaScript tests with the new debug() global! See below. New in Truffle v5.1.29: truffle debug --fetch-external. Debug transactions involving contracts not in your project that are verified on Etherscan! (And as of v5.1.32, it works with Sourcify too!) See below. New in Truffle v5.4.26: truffle debug --url . Debug transactions without needing a Truffle project or config! See below. Debugging a transaction on the blockchain is different than debugging traditional applications (for instance, applications written in C++ or Javascript). When debugging a transaction on the blockchain, you're not running the code in real-time; instead, you're stepping over the historical execution of that transaction, and mapping that execution onto its associated code. This gives us many liberties in debugging, in that we can debug any transaction, any time, so long as we have the code and artifacts for the contracts the transaction interacted with. Think of these code and artifacts as akin to the debugging symbols needed by traditional debuggers. In order to debug transactions, you'll need the following: Truffle 4.0 or above. The hash of a transaction on your desired blockchain. (If you are using the built-in blockchain and trying to debug a test execution, you may obtain the hash by running truffle develop --log.) The source code and artifacts the transaction encounters. Note that it's okay if your desired transaction resulted in an exception or if it ran out of gas. The transaction still exists on chain, and so you can still debug it! Warning: Debugging a transaction against a contract that was compiled with optimization enabled may not work reliably. In-test debugging¶ Truffle v5.1 and above provides the truffle test --debug flag and associated debug() global function, allowing you to interrupt tests to debug specific operations. Instead of capturing the transaction hash as described below, simply wrap any contract operation with debug(), like so: it("should succeed", async function() { // wrap what you want to debug with `debug()`: await debug( myContract.myFunction(accounts[1], { from: accounts[0] }) ); // ^^^^^^^^^^^^^^^^^^ wrap contract operation ^^^^^^^^^^^^^^}); Then, run truffle test --debug. Truffle will compile your sources and run your tests as normal until reaching the operation in question. At this point, Truffle will interrupt the normal test flow and start the debugger, allowing you to set breakpoints, inspect Solidity variables, etc. See Writing tests in JavaScript for more information on truffle test, and see Interacting with your contracts to learn about contract operations. Note: This feature currently doesn't work with

If the tile in front of the pig is occupied (e.g., by a fence) the truffle is instead placed one tile further. If that tile is occupied, the truffle is placed one tile further, and so on. This can lead to truffles being spawned outside of a fenced area.Prerequisites for Truffle GenerationA pig will produce a truffle only if all of the following are true:the pig has been fedthe pig has been let outside the barnit is not raining/stormingit is not winterthere are tiles available outside upon which to place a truffleChance to Produce the First TruffleA pig has a 0.02% chance on each frame to generate a truffle if:it has not yet generated a truffle for the dayit is standing on a free tileThis means that there is around a 99.99% chance that a pig will generate a truffle each day, with the assumption that it is walking around on mostly free tiles. Friendship does not affect this check; a pig with 0 friendship will still have a 99.99% chance to generate one truffle per day.Once a pig has found the first truffle for the day, it can continue to find truffles.The chance to find an extra truffle is Animal Friendship / 1500. This means that at max friendship (1000), there is a 66% chance of creating an extra truffle.Multiple extra truffles can be made until the animal fails this check.The average number of truffles a pig at max happiness produces in a day is ≈3 .ProfessionsTruffles benefit from professions such as Gatherer, allowing for double harvest, as well as Botanist, making all Truffles iridium quality.However, Truffles do not benefit from the Rancher profession.Gathering FrequencyTruffles that are not gathered will stay on the ground until the next day. This means that a player can continually let Truffles build up,

Reverted transactions; until we fix this, you can debug those with direct use of truffle debug. Debugging read-only calls¶ Running the debugger from inside your JS tests allow additional functionality beyond which truffle debug can provide. Beyond just debugging transactions, in-test debugging allows you to debug read-only calls as well. it("should get latest result", async function() { // wrap what you want to debug with `debug()`: const result = await debug( myContract.getResult("latest") ); // ^^^^^ read-only function ^^^^^}); Command¶ To use the debugger, gather the transaction you'd like to debug then run the following: $ truffle debug hash> Using a transaction starting with 0x8e5dadfb921dd... as an example, the command would look as follows: $ truffle debug 0x8e5dadfb921ddddfa8f53af1f9bd8beeac6838d52d7e0c2fe5085b42a4f3ca76 This will launch the debugging interface described below. If you simply want to open the debugger to get it ready, so that you can debug a transaction later, you can also simply run: Regardless of how you start the debugger, once it is running you are not limited to debugging only the transaction you launched it with; it is possible to unload the current transaction and load a new one, as described below. You can specify the network you want to debug on with the --network option: $ truffle debug [ hash>] --network Also, instead of --network, you can use --url with the URL of a provider; with this option, you can use Truffle Debugger outside of a Truffle project and without a Truffle config. This is primarily useful with the --fetch-external option. $ truffle debug [ hash>] --url If you want to debug your Solidity test contracts, you can pass the --compile-tests option: $ truffle debug [ hash>] --compile-tests And with the --fetch-external option (see below), you can debug contract instances outside your project that have verified source code on Etherscan or Sourcify. When using this option, you must specify a transaction hash to debug, and you will not be able to switch transactions from inside the debugger. $ truffle debug hash> --fetch-external --network Faster debugger startup: If your project was not compiled all at once (or under certain other conditions), the debugger will have to do its own compile of your project on startup. This can be very slow. If you compile your whole project at once, however, the debugger can likely avoid the initial recompile, speeding up startup greatly. Debugging external contracts with verified source¶ If you pass the --fetch-external option, the debugger will attempt to download verified source code off of Etherscan and Sourcify for any addresses involved in the transaction that it cannot find source code for in your project. You can of course debug such transactions without this option, but when stepping through the transaction the external
