rbenv is a Ruby version manager and shell environment manager designed to install, switch between, and manage multiple versions of the Ruby programming language. It functions as a project runtime isolator and an extensible versioning framework that ensures the correct Ruby binaries are executed based on the current context. The system uses a shim-based command interception model to resolve the active version before delegating execution to the binary. It allows for locking specific Ruby versions and environment variables to individual directories, ensuring project environment isolation. The ar
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 downlo
Pex is a Python application bundler and isolated environment manager. It packages programs and their entire dependency trees into single executable files to simplify deployment across different environments. The tool functions as a portable executable creator by bundling multiple platform-specific distributions into a single file. This ensures that a program can run across different operating systems by mapping target platforms to compatible binary distributions. The system provides capabilities for dependency management and isolated execution. It can launch scripts or interpreters within te
Vfox is a command-line utility designed to manage multiple programming language runtimes and development tools on a single machine. It provides a unified interface for installing, switching, and configuring software versions across different operating systems, ensuring consistent development environments. The project distinguishes itself through a modular, plugin-based architecture that allows for the integration of diverse language runtimes and utilities beyond built-in defaults. It utilizes a combination of shim-based execution, symlink management, and dynamic shell-hook environment injecti
RVM is a Ruby version manager and build automation tool designed to install and switch between multiple versions of the Ruby interpreter on a single system. It serves as a dependency isolator and shell environment wrapper, allowing for the creation of named library sets to prevent version conflicts between different projects.
The main features of rvm/rvm are: Per-Project Library Isolations, Multi-Interpreter Support, Ruby Version Managers, Environment Wrappers, Isolated Environment Managers, Language Environment Provisioning, Dependency Isolation, Runtime Version Switching.
