NAME

bundle-pristine - Restores installed gems to their pristine condition

SYNOPSIS

bundle pristine

DESCRIPTION

pristine restores the installed gems in the bundle to their pristine

condition using the local gem cache from RubyGems. For git gems, a

forced checkout will be performed.

For further explanation, bundle pristine ignores unpacked files on

disk. In other words, this command utilizes the local .gem cache or the

gem's git repository as if one were installing from scratch.

Note: the Bundler gem cannot be restored to its original state with

pristine. One also cannot use bundle pristine on gems with a 'path'

option in the Gemfile, because bundler has no original copy it can

restore from.

When is it practical to use bundle pristine?

It comes in handy when a developer is debugging a gem. bundle pristine

is a great way to get rid of experimental changes to a gem that one may

not want.

Why use bundle pristine over gem pristine --all?

Both commands are very similar. For context: bundle pristine, without

arguments, cleans all gems from the lockfile. Meanwhile, gem pristine

--all cleans all installed gems for that Ruby version.

If a developer forgets which gems in their project they might have been

debugging, the Rubygems gem pristine [GEMNAME] command may be inconve-

nient. One can avoid waiting for gem pristine --all, and instead run

bundle pristine.
