RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them. It is analogous to EasyInstall for the Python programming language. RubyGems is now part of the standard library from Ruby version 1.9.
Gems
Gems are packages similar to Ebuilds. They contain package information along with files to install.
Gems are usually built from ".gemspec" files, which are YAML files containing information on Gems. However, Ruby code may also build Gems directly. Such a practice is usually used with Rake.
gem command
The gem command is used to build, upload, download, and install Gem packages.
gem usage
RubyGems is very similar to apt-get, portage, yum and Npm in functionality.
Installation:
gem install mygem
Uninstallation:
gem uninstall mygem
Listing installed gems:
gem list --local
Listing available gems, e.g.:
gem list --remote
Create RDoc documentation for all gems:
gem rdoc --all
Download but do not install a gem:
gem fetch mygem
Search available gems, e.g.:
gem search STRING --remote
gem package building
The gem command may also be used to build and maintain .gemspec and .gem files.
Build .gem from a .gemspec file:
gem build mygem.gemspec
