Key Takeaways

1. ASDF simplifies managing multiple Go versions across projects.
2. It supports global and local Go version settings.
3. Easy installation, updating, and removal of Go versions.

Managing multiple versions of Go (Golang) can be challenging, especially when working on different projects that require different versions. ASDF, a powerful version manager, allows developers to easily install and switch between multiple Go versions. This guide will walk you through the process of setting up and using ASDF for Go.

What is ASDF?

ASDF is a flexible runtime version manager that allows you to manage multiple versions of various programming languages with a single command-line interface. It supports many languages, including Go, Node.js, Python, and Ruby, through community-maintained plugins.

Using ASDF for Go has several advantages:

• Easily install and switch between different Go versions.
• Project-specific Go versions using .tool-versions files.
• Consistent version management across different development environments.

Prerequisites

Before you begin, ensure you have the following installed on your system:

• Git (for installing ASDF and plugins)
• Curl or Wget (for downloading ASDF)
• ASDF (if not installed, follow the steps below)

---

Installing ASDF

If you haven't installed ASDF yet, you can do so with the following commands:

macOS (using Homebrew)

brew install asdf

Linux

git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.13.1
echo '. "$HOME/.asdf/asdf.sh"' >> ~/.bashrc
echo '. "$HOME/.asdf/completions/asdf.bash"' >> ~/.bashrc
source ~/.bashrc

For Zsh users, replace .bashrc with .zshrc.

Verify that ASDF is installed correctly:

asdf --version

---

Installing the Go Plugin for ASDF

To manage Go versions, you need to install the Go plugin for ASDF:

asdf plugin add golang https://github.com/kennyp/asdf-golang.git

Check if the plugin is installed:

asdf plugin list

This should display golang in the list.

Installing and Managing Go Versions

List Available Go Versions

To see all available versions of Go:

asdf list all golang

Install a Specific Go Version

To install a specific version of Go, use:

asdf install golang 1.22.0

Replace 1.22.0 with the version you need.

Set the Global Go Version

To set a default (global) Go version:

asdf global golang 1.22.0

Set a Local Go Version (Per Project)

To specify a Go version for a particular project:

cd /path/to/your/project
asdf local golang 1.21.1

This will create a .tool-versions file inside the project directory.

Verify Installed Version

To check the current Go version:

go version

---

Updating Go Versions

To update Go, first list installed versions:

asdf list golang

To install the latest available version:

asdf install golang latest

Then, update the global version:

asdf global golang latest

---

Uninstalling a Go Version

To remove a specific Go version:

asdf uninstall golang 1.21.1

---

Additional ASDF Commands

• Check Installed Plugins

  asdf plugin list

• Update ASDF and Plugins

  asdf update
  asdf plugin update --all

• Remove a Plugin

  asdf plugin remove golang

---
