Gem::Repackager Build Status

Have you ever been without internet and needed a gem but it's in the wrong RVM gemset? How about attempting to correct a problem with a production environment and need to clone the exact gems available? Perhaps you are attempting a full app stack backup for compliance purposes?

Gem::Repackager packages one or more of your installed gems back into .gem files for easy transportation. Gem::Repackager comes with a command-line utility to facilitate, with easy extensibility in the code as well.

Installation

It's a gem, so install it. gem install gem_repackager or add it to bundler.

Usage

The command-line utility is as follows:

gem_repackager DIRECTORY [options]

This will repackage all gems in DIRECTORY and place the resulting .gem files in DIRECTORY. DIRECTORY refers to the location of your installed directories. Note that this is the directory that contains specifications, bin, gems, etc, and not the gems directory itself. In RVM, this is usually along the lines of ~/.rvm/gems/GEMSET or simply $GEM_HOME.

By default, gem_repackager places the packaged gems into DIRECTORY. To change this, pass the --destination DIR parameter and the resulting gems will be moved there.

Options

  • --gems gem-version[,gem-version,...] - A comma-separated list of gems in "GEM-VERSION"
  • --destination DIR - Location to store the packaged .gem files to. If this is not passed, it will default to DIRECTORY
  • --[no]-verbose - Toggle verbose mode. This includes Gem::Specification warnings, so this could get noisy.

Here's an example of packaging all gems in my current RVM gemset to a custom directory:

gem_repackager $GEM_HOME --destination=~/gem_export

And here is how you would package all of the rspec 2.11.0 gems to the default directory:

gem_repackager $GEM_HOME --gems rspec-2.11.0,rspec-core-2.11.0,rspec-expectations-2.11.2,rspec-mocks-2.11-1

Contributing

Pull requests welcome, preferably with tests because I am lazy and do not want to run every command to make sure changes did not break anything.
