Elsetup

Elsetup is a command-line utility used for setting up and configuring the Elixir programming language environment on a system. It automates the process of downloading, installing, and managing Elixir versions, along with their dependencies, making it easier for developers to get started with Elixir development.

The primary function of elsetup is to streamline the installation and management of Elixir. It allows users to specify which version of Elixir they wish to install, including the latest stable release or specific older versions for compatibility purposes. Once installed, elsetup can also be used to switch between different installed Elixir versions, which is particularly useful when working on projects that require different Elixir runtimes.

Beyond managing Elixir itself, elsetup often handles the installation of Erlang/OTP, as Elixir runs on the Erlang Virtual Machine (BEAM). This dependency is crucial for Elixir's functionality. The tool typically downloads the appropriate Erlang/OTP version that is compatible with the selected Elixir version.

To use elsetup, users typically run it from their terminal or command prompt. The commands are generally straightforward, often involving subcommands to install, uninstall, list, or switch Elixir versions. This command-line interface makes it suitable for scripting and integration into automated build or deployment processes. Elsetup aims to abstract away the complexities of manual installation, providing a consistent and reliable method for setting up the Elixir development environment across different operating systems.
