Struct ReadFileWaitFunc

lang/core/os/readfilewait.go:63–73

ReadFileWaitFunc is a function that reads the full contents from a local file. If the file contents change or the file path changes, a new string will be sent. This is different from the normal readfile in that if will not error if the file doesn't exist. If the file is not found, it returns the emp

// string. If the file re-appears, it returns those new contents. This function
// will eventually be deprecated when the function graph error system is stable.
type ReadFileWaitFunc struct {
	interfaces.Textarea

	init *interfaces.Init

	recWatcher *recwatch.RecWatcher
	events     chan error // internal events

	input    chan string // stream of inputs
	filename *string     // the active filename
}

// String returns a simple name for this function. This is needed so this struct
// can satisfy the pgraph.Vertex interface.
