This is the devcontainer environment for using atgo.
atgo is a tool for playing AtCoder by Go language.

• 日本語

AtCoder provides the Go language environment in version 1.20.6, but the latest version of Go language is 1.22 or later.
Since the Go language is backward compatible, code written in 1.20 will in principle work in 1.22 or later as long as the version is specified in go.mod.
However, it is not guaranteed that the behavior will be the same, so even if the code is executed correctly in a local test, it may cause a WA on AtCoder due to a different behavior.
To solve this problem, it is necessary to prepare 1.20.6 go in the local environment, but the container environment can easily supply it.

• Environment to launch containers such as Docker
• Visual Studio Code and Dev Containers

Run the following command on the root directory of the workspace where you will be working with AtCoder using atgo.

$ git clone https://github.com/meian/devcontainer-atgo-go .devcontainer

Then open it on vscode as devcontainer on vscode using the Dev Containers.

atgo is installed when the container is started, so you can use it with vscode in devcontainer.

# Authenticate
$ atgo auth

# Display contest info.
$ atgo contest abc123

# Create task implements files in your workspace
$ atgo task local-init abc123_a

Subcommand completion with bash-completion is also available.

When the latest version of atgo is released, you can update it with the following command.

# update script
# If the latest version is released locally, nothing will be processed
$ update-atgo

# Force re-installation of the latest version locally
# (not sure if there is a needs or not)
$ update-atgo -f

The following extensions are automatically installed when devcontainer is started.
