Functions

func FuncBar

func FuncBar(a, b fgbase.Edge, x fgbase.Edge, sink bool) fgbase.Node

FuncBar waits for both inputs and returns the one that matches the shortest string. Returns nil if no match at all.

func FuncMatch

func FuncMatch(a, b fgbase.Edge, x fgbase.Edge, ignoreCase bool) fgbase.Node

FuncMatch advances a byte slice if it matches a string, otherwise returns the empty slice

func FuncRepeat

func FuncRepeat(newmatch, subsrc, dnstreq fgbase.Edge, oldmatch, subdst, upstreq fgbase.Edge, min, max int) fgbase.Node

FuncRepeat repeats a match zero or more times

inputs: newmatch -- new match string subsrc -- fedback result of last match, successful (remainder string) or not (nil) dnstreq -- receive downstream request for new remainder string

outputs: oldmatch -- continue match (remainder string) subdst -- match done, successful (remainder string) or not (nil) upstreq -- send upstream request for new remainder string

func NextID

func NextID() int64

Types

type Mode

type Mode int

func (Mode) String

func (m Mode) String() string

type Search

type Search struct {
	Curr  string
	Orig  string
	State Mode
	ID    int64
}
