gemfile(install = false, options = {}, &gemfile) click to toggle source

Allows for declaring a Gemfile inline in a ruby script, optionally installing any gems that aren’t already installed on the user’s system.

@note Every gem that is specified in this ‘Gemfile’ will be ‘require`d, as if

the user had manually called `Bundler.require`. To avoid a requested gem
being automatically required, add the `:require => false` option to the
`gem` dependency declaration.

@param install [Boolean] whether gems that aren’t already installed on the

user's system should be installed.
Defaults to `false`.

@param gemfile [Proc] a block that is evaluated as a ‘Gemfile`.

@example Using an inline Gemfile

  gem 'json', require: false
  gem 'nap', require: 'rest'
  gem 'cocoapods', '~> 0.34.1'
end
