Tutorial - Install and Setup the Ultra Smart Contract Toolkit Extension ​

Prerequisites ​

Goal ​

The goal of this tutorial is to install the Ultra Smart Contract Toolkit extension and getting started with writing smart contracts.

Installation ​

You can download the extension from VS Code Market Place, or you can manually install it via VS Code.

To install the extension via VSCode, follow these steps:

  1. Open up your VS Code and click on the Extensions tab, or press Ctrl + Shift + X
  2. Under the Extensions tab, search for ultra-cpp
  3. Click on the Install button

You have now successfully installed the Ultra Smart Contract Toolkit Extension. To verify the installation, make sure you have ᕫ API item in the VS Code status bar.

Scaffolding ​

Depending on where you want to start your project. Always start with a workspace folder and open it in VSCode.

Once you have the Ultra Smart Contract Toolkit extension installed, you can easily create a starting template.

Access the Command Palette in VS Code with F1 on the keyboard.

Command Palette Command ​

Ultra: Create Smart Contract

It will prompt you for a folder to put the source code under. It is recommended to use src if it's a single contract.

Header Setup ​

After creating the contract, you will need to install headers to remove some of the errors you will get from VSCode about the code.

There are currently two ways to install headers.

  • First way is to open your .cpp file that was generated, and follow the prompts
  • The second way is to open the the Command Palette (F1) and search for Ultra: Add C++ Header Files for EOSIO

Make sure you agree to both prompts (Add Ultra.io Header Files and Add C++ Support):

After installation, and following the prompts, the VS Code window will restart itself.

Wait for intellisense to finish updating to ensure everything is working correctly.

Any other prompts from VS Code can be ignored (including prompts related to Docker or CMake Tools if you have those installed)

What's next? ​

The next tutorial will cover compiling smart contracts using the VS Code extension. See Smart Contract Compiling for more information.
