Rbenv
rbenv is a Ruby version manager and shell shim environment manager. It allows for the installation of multiple Ruby versions on a single machine and coordinates the selection of the active version based on the current directory or shell session.
The tool functions as an extensible command line framework that intercepts executable calls using shell shims. These shims route requests to the selected language version, ensuring environment isolation by storing binaries in independent directories.
The system includes capabilities for language runtime administration, including the ability to download and compile specific Ruby versions. It also features a plugin system that enables the addition of custom commands and scripts to modify the runtime workflow.
Features
- Command Interception Shims - Intercepts executable calls using lightweight shell shims to route requests to the currently active Ruby version.
- Shell Environment Managers - Manages the shell environment by injecting shims into the system path to route command execution.
- Version Managers - Provides a system for installing, switching, and managing multiple versions of the Ruby runtime.
- Language Environment Coordination - Coordinates multiple installed Ruby versions using shell shims to ensure the correct binary is executed.
- Language Runtime Administration - Manages multiple Ruby installations and automates version selection based on the current directory.
- Ruby Version Managers - Provides comprehensive management of multiple Ruby versions and directory-based version switching.
- Environment Isolation - Ensures each application runs with its own specific Ruby version to maintain environment consistency.
- Multi-Version Installations - Downloads and compiles specific versions of Ruby into isolated managed directories.
- Directory-Based Version Resolution - Provides automatic Ruby version switching by detecting configuration files within the project directory hierarchy.
- Isolated Runtime Directories - Stores separate Ruby versions in independent directories to prevent binary conflicts on the local file system.
- Environment Path Injections - Modifies the system path to prioritize the shim directory, ensuring the selected Ruby version is executed.
- Extensible Command-Line Interfaces - Functions as an extensible command-line framework for modifying how language environments are managed.
- Plugin Systems - Ships a plugin system for adding new commands and customizing internal mechanisms using external scripts.
- Plugin-Based Architectures - Implements a plugin architecture that allows extending core functionality by loading external scripts from a dedicated directory.
- Environment Management - Manage multiple Ruby versions for different projects.
