ruby-standalone(1)


NAME

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

USAGE

   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) 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.
