Overview
Clarinet is a local development environment that offers everything you need to create, test, and deploy smart contracts on Stacks.
Using a simple command line interface, Clarinet enables you to build and iterate on your contracts locally before moving into production on the mainnet network.
You can code with Clarity syntax support, run tests, debug your code line by line, and deploy your contracts to a local Stacks blockchain environment to rapidly iterate on your code. Clarinet can also be used as a hosted service in the cloud via the Hiro Platform.
Installation
$brew install clarinet
Set up shell completions
Clarinet already has many different commands built in. Therefore, enabling tab completion in your shell may be useful. Using the command below, you can use clarinet to generate the shell completion scripts for many common shells.
$clarinet completions (bash|elvish|fish|powershell|zsh)
After generating the file, you can refer to the documentation for your shell to determine where this file should be moved to and what other steps may be necessary to enable tab completion for clarinet.
