Types

type Bounds

type Bounds struct {
	Low, High rune
}

func (*Bounds) Contains

func (b *Bounds) Contains(r rune) bool

type Node

type Node struct {
	Type     NodeType
	Value    string
	Children []*Node
	Leaf     bool
	Name     []string // Only valid on leaf nodes. List of names of patterns terminate that on this leaf node
	Range    *Range
}

func Merge

func Merge(root1, root2 *Node) *Node

func Parse

func Parse(name, input string) (*Node, error)

func (*Node) Index

func (n *Node) Index(s string) int

Index returns the first index of the Node's expression in the string.

func (*Node) LastIndex

func (n *Node) LastIndex(s string) int

LastIndex returns the last index of the Node's expression in the string. For ranges, it returns the beginning of the last blob

type NodeType

type NodeType int

const (
	TypeRoot NodeType = iota
	TypeAny
	TypeText
	TypeRange
)

func (NodeType) String

func (i NodeType) String() string

type Range

type Range struct {
	Repeated bool
	Inverse  bool
	Bounds   []*Bounds
	CharList string
}

func (*Range) Matches

func (r *Range) Matches(ru rune) bool

Matches returns true if the rune is matched by the Range.
