Overview

Specifies a logical code package be mapped. This can be a project source folder, a Gem, or a builtin.

Options:

  • path indicates a relative path to a code folder.

  • gem may indicate a gem name that “owns” the path

  • require_name can be used to make sure that the code is required so that it can be loaded. This is generally used with builtins, or when the path to be required is not automatically required when bundler requires the gem.

  • exclude can be used used to exclude sub-paths. Generally not used with gem.

  • labels is used to apply labels to matching code. This is really only useful when the package will be applied to specific functions, via TargetMethods.

  • shallow indicates shallow mapping, in which only the entrypoint to a gem is recorded.

def build_from_builtin(path, shallow: false, require_name: nil, exclude: [], labels: [])
  Package.new(path, path, nil, require_name, exclude, labels, shallow, true)
end

.build_from_gem(gem, shallow: true, require_name: nil, exclude: [], labels: [], optional: false, force: false) ⇒ Object

Builds a package for gem. Generally corresponds to a ‘gem:` entry in appmap.yml. Also used when mapping a builtin.

  if path
    Package.new(gem, path, gem, require_name, exclude, labels, shallow)
  else
    AppMap::Util.startup_message "#{gem} is not available in the bundle"
  end
end

.build_from_path(path, shallow: false, require_name: nil, exclude: [], labels: []) ⇒ Object

Builds a package for a path, such as ‘app/models` in a Rails app. Generally corresponds to a `path:` entry in appmap.yml. Also used for mapping specific methods via TargetMethods.

Instance Method Details

#shallow? ⇒ Boolean

Indicates that only the entry points to a package will be recorded. Once the code has entered a package, subsequent calls within the package will not be recorded unless the code leaves the package and re-enters it.

Returns:

  • (Boolean)

def shallow?
  shallow
end

#subpackage(location, config) ⇒ Object

Clones this package into a sub-package, if needed. For example, suppose the appmap.yml specifies package ‘app/models`. If some code in `app/models/dao/user.rb` is mapped, it will be associated with a sub-package `app/models/dao`.
