File updaters

File updaters update a dependency file to use the latest version of a given dependency. They rely on information provided to them by update checkers.

There is a Dependabot::FileUpdaters class for each language Dependabot supports.

Public API

Each Dependabot::FileUpdaters class implements the following methods:

Method Description
.updated_files_regex An array of regular expressions matching the names of the files this class updates. Intended to be used by integrators when checking whether a commit may cause merge-conflicts with a dependency update pull request.
#updated_dependency_files Returns an array of updated Dependabot::DependencyFile instances, with their content updated to include the updated dependency.

An integration might look as follows:

require 'dependabot/file_updaters'

unless update_checker.can_update?(requirements_to_update: :own)
  raise "Dependency doesn't need update!"
end
dependencies = update_checker.updated_dependencies(requirements_to_update: :own)

file_updater_class = Dependabot::FileUpdaters::Ruby::Bundler
file_updater = file_updater_class.new(
  dependencies: dependencies,
  dependency_files: files,
  credentials: [{
    "type" => "git_source",
    "host" => "github.com",
    "username" => "x-access-token",
    "password" => "token"
  }]
)

file_updater.updated_dependency_files.each do |file|
  puts "Updated #{file.name} with new content:\n\n#{file.content}"
end

Writing a file updater for a new language

All new file updaters should inherit from Dependabot::FileUpdaters::Base and implement the following methods:

Method Description
.updated_files_regex See Public API section.
#updated_dependency_files See Public API section.

To ensure the above are implemented, you should include it_behaves_like "a dependency file updater" in your specs for the new file updater.
