Overview

Bundler provides a consistent environment for Ruby projects by tracking and installing the exact gems and versions that are needed.

Since Ruby 2.6, Bundler is a part of Ruby's standard library.

Bunder is used by creating gemfiles listing all the project dependencies and (optionally) their versions and then using

require 'bundler/setup'

or .setup to setup environment where only specified gems and their specified versions could be used.

See website for extensive documentation on gemfiles creation and Bundler usage.

As a standard library inside project, Bundler could be used for introspection of loaded and required modules.

.require(*groups)

Setups Bundler environment (see .setup) if it is not already set, and loads all gems from groups specified. Unlike .setup, can be called multiple times with different groups (if they were allowed by setup).

Assuming Gemfile

group :test do
  gem 'second_gem', '= 1.0'
end

The code will work as follows:

Bundler.setup # allow all groups
Bundler.require(:default) # requires only first_gem
# ...later
Bundler.require(:test)   # requires second_gem

.setup(*groups)

Turns on the Bundler runtime. After setup call, all .load or .require of the gems would be allowed only if they are part of the Gemfile or Ruby's standard library. If the versions specified in Gemfile, only those versions would be loaded.

Assuming Gemfile

gem 'first_gem', '= 1.0'
group :test do
  gem 'second_gem', '= 1.0'
end

The code using setup works as follows:

require 'third_gem' # allowed, required from global gems
require 'first_gem' # allowed, loads the last installed version
Bundler.setup
require 'fourth_gem' # fails with LoadError
require 'second_gem' # loads exactly version 1.0

setup can be called only once, all subsequent calls are no-op.

If groups list is provided, only gems from specified groups would be allowed (gems specified outside groups belong to special :default group).

To require all gems from Gemfile (or only some groups), see .require.

# File 'lib/bundler.rb', line 139
