We have all become familiar with the concept of gemsets. They come in different shapes and sizes, and provide isolation for project dependencies. Some of the libraries that implement gemsets are rip, RVM and rbenv-gemset.
This library recreates the absolutely minimal feature set for creating and using gemsets.
This library provides a command line application called
are the available options:
Creates the $PWD/.gs directory.
Displays the documentation.
When called with no arguments, it starts a shell session and configures the variables GEM_HOME, GEM_PATH and PATH to point to the $PWD/.gs directory. In addition, it sets the GS_NAME variable with the name of the current gemset (useful for PS1).
When called with arguments other than init or help, it will execute command in a gs shell session and return to the parent session once finished.
First, grab the gem:
$ gem install gs
gs init within your project and then just
gs to start
the subshell. The environment variables used by RubyGems will now
point to the
.gs directory, and every gem you install, every gem you
remove, will use that path.
