Overview

Habitat Package Ident

This class builds a Habitat Package Identifier object using the four components of a Habitat package: origin, package name (pkg), version, and release. It subclasses Struct with arguments that have default values - 'latest' for version and release. It also implements a method to return the package identifier as a / separated string for use in the Habitat Depot API rubocop:disable StructInheritance

Constructor Details

#initialize(origin, pkg, version = 'latest', release = 'latest') ⇒ PackageIdent

Creates the package identifier using the origin and package name. Optionally will also use the version and release, or sets them to latest if not specified.

Attributes

  • origin - The package origin
  • pkg - The package name
  • version - The version of the package
  • release - The timestamp release of the package

Examples

Use the latest core/zlib package:

Habitat::PackageIdent.new('core', 'zlib')

Use version 1.2.8 of the core/zlib package:

Habitat::PackageIdent.new('core', 'zlib', '1.2.8')

Use a specific release of version 1.2.8 of the core/zlib package:

Habitat::PackageIdent.new('core', 'zlib', '1.2.8', '20160222155343')

Pass an array as an argument:

Habitat::PackageIdent.new(*['core', 'zlib'])

For example, from a #split string:

Habitat::PackageIdent.new(*'core/zlib'.split('/'))
