Method getOrAppend

internal/shellgen/flake_input.go:207–217

getOrAppend returns a pointer to the slice element with a given key. If the key doesn't exist, a new element is automatically appended to the slice. The pointer is valid until the next append.

(key string)

// key doesn't exist, a new element is automatically appended to the slice. The
// pointer is valid until the next append.
func (k *keyedSlice) getOrAppend(key string) *flakeInput {
	if k.lookup == nil {
		k.lookup = make(map[string]int)
	}
	if i, ok := k.lookup[key]; ok {
		return &k.slice[i]
	}
	k.slice = append(k.slice, flakeInput{})
	k.lookup[key] = len(k.slice) - 1
	return &k.slice[len(k.slice)-1]
