|
# 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
|
|
#
|
|
# #!/usr/bin/env ruby
|
|
#
|
|
# require 'bundler/inline'
|
|
#
|
|
# gemfile do
|
|
# source 'https://rubygems.org'
|
|
# gem 'json', require: false
|
|
# gem 'nap', require: 'rest'
|
|
# gem 'cocoapods', '~> 0.34.1'
