bundle-pristine(1) -- 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 inconvenient. One can avoid waiting for `gem pristine --all`, and instead run `bundle pristine`.
