Overview ¶

Package lock reads and writes platformgo.lock: what platformgo has actually applied to a project.

platformgo.yaml says what the project wants; the lock says what it got. The difference between the two is what lets apply remove the files of a module that is no longer declared, so taking a module out never needs manual cleanup.

Functions ¶

func Marshal ¶

func Marshal(l Lock) ([]byte, error)

Marshal renders the lock as it is stored.

func SafePath ¶

func SafePath(path string) bool

SafePath reports whether a recorded path stays inside the project: the lock is a file in the repository, and a path like ../../etc must never be deleted because of it.

func Write ¶

func Write(dir string, l Lock) error

Write stores the lock. The content is sorted, so the file only changes when what has been applied changes.

Types ¶

type Diff ¶

type Diff struct {
	AddedModules   []string
	RemovedModules []string
	StaleFiles     []string // generated before and no longer generated
}

Diff is what changes between two locks.

func Compare ¶

func Compare(applied, wanted Lock) Diff

Compare returns the difference between the applied lock and the wanted one.

func (Diff) Empty ¶

func (d Diff) Empty() bool

Empty reports whether nothing changes.

type Lock ¶

type Lock struct {
	Platform  string   `yaml:"platform"`  // platform version the project was last applied with
	Modules   []string `yaml:"modules"`   // enabled modules
	Generated []string `yaml:"generated"` // files owned by generation
}

Lock is the content of platformgo.lock.

func Read ¶

func Read(dir string) (Lock, error)

Read loads the lock of a project. A project without a lock has an empty one: it has never been applied, which is what a project created before locks looks like.
