Types ¶
type String ¶
type String []rune
func (String) Append ¶
func (xs String) Append(add ...rune) StringDelta
func (String) Delete ¶
func (xs String) Delete(i, num int) StringDelta
func (String) DeleteElements ¶
func (xs String) DeleteElements(del ...rune) StringDelta
func (String) PrefixMatch ¶
PrefixMatch returns the number of elements at the beginning of xs that match the elements at the beginning of ys.
func (String) Retain ¶
func (xs String) Retain(r int) StringDelta
type StringDelta ¶
type StringDelta []StringOp
func StringDiff ¶
func StringDiff(a, b []rune) StringDelta
StringDiff produces a set of operations that can be applied to xs to produce a slice that would match slice b.
func (StringDelta) Delete ¶
func (x StringDelta) Delete(d int) StringDelta
func (StringDelta) Insert ¶
func (x StringDelta) Insert(add ...rune) StringDelta
func (StringDelta) Rebase ¶
func (x StringDelta) Rebase(base StringDelta) (StringDelta, error)
func (StringDelta) Retain ¶
func (x StringDelta) Retain(r int) StringDelta
type StringOp ¶
type StringOp interface {
// Leaves returns how many elements of a slice of length n would remain
// to be transformed by additional ops after applying this op. Returns
// a negative number if and only if this op cannot be coherently
// applied to a slice of length n.
Leaves(n int) int
// Len returns the number of elements inserted, retained, or deleted by
// this op.
Len() int
// Skip returns an equivalent op that assumes its intent is already carried
// out for the first n elements. May panic if n > Len().
Skip(n int) StringOp
// Rebase transforms op into a rebased op r (or nil), a subsequent op for
// rebasing xn (or nil), and a subsequent base bn (or nil).
Rebase(base StringOp) (r StringOp, xn StringOp, bn StringOp)
// Compact expands this op to include o if possible, returning true if
// successful.
Compact(o StringOp) (StringOp, bool)
Apply(String) (include String, remainder String)
