Types ¶

type Func ¶

type Func func(h parsley.History, leftRecCtx data.IntMap, r parsley.Reader, pos parsley.Pos) (parsley.Node, parsley.Error, data.IntSet)

Func defines a helper to implement the Parser interface with functions

func Nil ¶ added in v0.6.0

func Nil() Func

Nil always matches and returns with an nil node result

func (Func) Name ¶ added in v0.6.0

func (f Func) Name() string

Name returns with an empty name

func (Func) Parse ¶

func (f Func) Parse(h parsley.History, leftRecCtx data.IntMap, r parsley.Reader, pos parsley.Pos) (parsley.Node, parsley.Error, data.IntSet)

Parse parses the input using the function

func (Func) WithName ¶ added in v0.6.0

func (f Func) WithName(name interface{}) *NamedFunc

WithName returns with the same parser function but with the given name If a function is passed then it will be called when Name() is called

type History ¶

type History struct {
	// contains filtered or unexported fields
}

History records information about parser calls

func NewHistory ¶

func NewHistory() *History

NewHistory creates a history instance

func (*History) CallCount ¶

func (h *History) CallCount() int

CallCount returns with the call count

func (*History) GetResult ¶ added in v0.6.0

func (h *History) GetResult(parserIndex int, pos parsley.Pos, leftRecCtx data.IntMap) (*parsley.Result, bool)

GetResult return with a previously saved result

func (*History) RegisterCall ¶

func (h *History) RegisterCall()

RegisterCall registers a call

func (*History) SaveResult ¶ added in v0.6.0

func (h *History) SaveResult(parserIndex int, pos parsley.Pos, result *parsley.Result)

SaveResult registers a parser result for a certain position

type NamedFunc ¶ added in v0.6.0

type NamedFunc struct {
	// contains filtered or unexported fields
}

NamedFunc is a parser function with a custom name

func End ¶

func End() *NamedFunc

End matches the end of the input

func (*NamedFunc) Name ¶ added in v0.6.0

func (nf *NamedFunc) Name() string

Name returns with the parser name

func (*NamedFunc) Parse ¶ added in v0.6.0

func (nf *NamedFunc) Parse(h parsley.History, leftRecCtx data.IntMap, r parsley.Reader, pos parsley.Pos) (parsley.Node, parsley.Error, data.IntSet)

Parse parses the input using the function
