What is asdf?
asdf is a command-line interface (CLI) tool designed to manage runtime versions for various programming languages and development tools. It provides a single, unified interface to handle multiple runtimes, eliminating the need for separate version managers for each tool. Users can install, switch, and manage versions across different projects using a consistent set of commands.
The tool utilizes a plugin-based architecture, allowing it to support a wide range of existing runtimes and tools through an extensive ecosystem. It maintains backward compatibility by supporting existing configuration files such as .nvmrc, .node-version, and .ruby-version, facilitating smooth migration from other version managers. Configuration is centralized in a single .tool-versions file, which can be shared across teams and projects for consistent environment setup.
