Functions ¶

func Init ¶ added in v0.12.0

func Init(ed eddefs.Editor, ns eval.Ns)

Types ¶

type Fuser ¶

type Fuser struct {
	*sync.RWMutex
	// contains filtered or unexported fields
}

Fuser provides a unified view into a shared storage-backed command history and per-session history.

func NewFuser ¶

func NewFuser(store Store) (*Fuser, error)

func (*Fuser) AddCmd ¶

func (f *Fuser) AddCmd(cmd string) error

func (*Fuser) AllCmds ¶

func (f *Fuser) AllCmds() ([]string, error)

func (*Fuser) FastForward ¶ added in v0.12.0

func (f *Fuser) FastForward() error

func (*Fuser) SessionCmds ¶

func (f *Fuser) SessionCmds() []string

func (*Fuser) Walker ¶

func (f *Fuser) Walker(prefix string) *Walker

type List ¶ added in v0.11.0

type List struct {
	*sync.RWMutex
	Daemon *daemon.Client
}

List is a list-like value that provides access to history in the API backend. It is used in the $edit:history variable.

func (List) Equal ¶ added in v0.11.0

func (hv List) Equal(a interface{}) bool

Equal returns true as long as the rhs is also of type History.

func (List) Hash ¶ added in v0.11.0

func (hv List) Hash() uint32

func (List) Index ¶ added in v0.12.0

func (hv List) Index(rawIndex interface{}) (interface{}, error)

func (List) Iterate ¶ added in v0.11.0

func (hv List) Iterate(f func(interface{}) bool)

func (List) Kind ¶ added in v0.11.0

func (hv List) Kind() string

func (List) Len ¶ added in v0.11.0

func (hv List) Len() int

func (List) Repr ¶ added in v0.11.0

func (hv List) Repr(int) string

type Store ¶

type Store interface {
	NextCmdSeq() (int, error)
	AddCmd(cmd string) (int, error)
	Cmds(from, upto int) ([]string, error)
	PrevCmd(upto int, prefix string) (int, string, error)
}

Store is the interface of the storage backend.

type Walker ¶

type Walker struct {
	// contains filtered or unexported fields
}

Walker is used for walking through history entries with a given (possibly empty) prefix, skipping duplicates entries.

func NewWalker ¶

func NewWalker(store Store, upper int, cmds []string, seqs []int, prefix string) *Walker

func (*Walker) CurrentCmd ¶

func (w *Walker) CurrentCmd() string

CurrentSeq returns the content of the current entry.

func (*Walker) CurrentSeq ¶

func (w *Walker) CurrentSeq() int

CurrentSeq returns the sequence number of the current entry.

func (*Walker) Next ¶

func (w *Walker) Next() (int, string, error)

Next reverses Prev.

func (*Walker) Prefix ¶

func (w *Walker) Prefix() string

Prefix returns the prefix of the commands that the walker walks through.

func (*Walker) Prev ¶

func (w *Walker) Prev() (int, string, error)

Prev walks to the previous matching history entry, skipping all duplicates.
