Railsenv

Railsenv is a command-line tool designed to simplify the management of multiple Ruby on Rails environments on a single machine. It allows developers to easily switch between different Rails versions and project-specific dependencies, ensuring that each project can run with its required setup without conflicts.

The primary function of Railsenv is to isolate Ruby versions and gem sets for each Rails application. This is achieved through a system of environment variables and directory structures. When a developer navigates into a project directory managed by Railsenv, the tool automatically detects the specified Ruby version and gem set for that project and activates them in the current shell session. This eliminates the need for manual configuration or the potential for version clashes that can arise when working on multiple projects simultaneously.

Railsenv supports integration with popular Ruby version managers like rbenv and RVM, allowing users to leverage existing Ruby installations. Its configuration is typically managed through a `.railsenv` file within the project's root directory, where developers can specify the desired Ruby version, gem file, and other project-specific settings. This approach promotes a cleaner development workflow and makes it straightforward to onboard new team members by providing a clear definition of the project's requirements.
