NAME

       ruby-standalone - use (only) the Ruby interpreter from Debian

SYNOPSIS

       ruby-standalone
       ruby-standalone [PROGRAM] [ARGS]

DESCRIPTION

       ruby-standlone  allows  one  to  use the Ruby interpreter provided by Debian (and thus get
       security support for stable releases), without having  to  also  use  Ruby  libraries  and
       applications from Debian.

       When  called  with  no arguments, ruby-standalone will spawn a new shell, where all of the
       standard Ruby programs (ruby, erb, gem, irb, rdoc, ri, testrb) in  $PATH  will  never  use
       code from Debian-provided packages.

       Otherwise, PROGRAM will be called with ARGS as arguments, in that same context.

       Caveat: if PROGRAM is not installed as a Rubygem and is installed by a Debian package, the
       Debian package version will be used.

USE CASES

       ruby-standalone makes it possible to:

       ○   install vagrant from the Debian repository and at the sime time  develop  a  Ruby  web
           application  that  needs gem versions different than the ones that were pulled in from
           the Debian repository when vagrant was installed.

       ○   install chef from the Debian repository on a node that will host an  application  that
           needs different gem versions than the ones chef needs.

       ○   on  the  same  server,  host redmine installed from the Debian repository and in-house
           Rails application that needs  a  different  version  of  Rails  than  the  one  Debian
           provides.
