Swanky dev container

Intro

Dev container is a Visual Studio Code extension that allows for sharing a full dev environment.

This means you can develop your project inside a preconfigured container with all prerequisites met and correct dependencies installed. This includes Rust compiler, cargo contract and swanky-cli.

Prerequisites

To run the container, you will need:

More detailed information on system requirements can be found here.

Software versions

Swanky dev container comes with cargo contract v2 and swanky-cli v3 installed, supporting and optimized for ink! v4 and above. If you need an older version, please refer to the environmet setup docs and swanky-cli update guide

Usage

  • This is a template repo, create a new repo from this template, or clone it
  • open the repo in VS Code

There should be a popup in the lower-right offering you to open the container. Click "Reopen in Container".

You can also click on the green button on the lower-left to open the dev container commands menu, and select "Reopen in container" from there.

Terminal

To interact with your project (including calling swanky commands), use VS Code integrated terminal.

Updating swanky version

Swanky is installed into /opt/swanky, and the main executable is linked to /usr/local/bin/swanky.

To update the Swanky version you can use the following steps:

sudo rm -rf /opt/swanky /usr/local/bin/swanky
wget -O /tmp/swanky.tar.gz [new_version_url]
sudo tar -xf /tmp/swanky.tar.gz -C /opt
sudo ln -s /opt/swanky/bin/swanky /usr/local/bin/swanky

Adding vscode extensions

Any VS code extensions you need to run during the development in the container need to be specified in the devcontainer.json file.

To add the extensions you want, copy the identifier found in the extension details page into the customizations.vscode.extensions array in devcontainer.json

Add features

Features are "modules" that can be added to the dev container to install additional software or extend the functionality.

Officially supported and community maintained features can be found here, but you can also build your own.

To add a feature, simply copy it's reference into the features field.

Note: not all features are compatible, and some need to be installed in a specific order. Check the readme before adding any.
