type Lexer

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

func NewLexer

func NewLexer(in io.Reader) *Lexer

NewLexer creates a new lexer without init.

func NewLexerWithInit

func NewLexerWithInit(in io.Reader, initFun func(*Lexer)) *Lexer

NewLexerWithInit creates a new Lexer object, runs the given callback on it, then returns it.

func (*Lexer) Column

func (yylex *Lexer) Column() int

Column returns the current column number. The first column is 0.

func (*Lexer) Error

func (yylex *Lexer) Error(e string)

func (*Lexer) Lex

func (yylex *Lexer) Lex(lval *yySymType) int

Lex runs the lexer.

func (*Lexer) Line

type LexerBuilder

type LexerBuilder struct {
	Standalone   bool
	CustomError  bool
	CustomPrefix string
	// contains filtered or unexported fields
}

func (*LexerBuilder) DumpFormattedLexer

func (b *LexerBuilder) DumpFormattedLexer(program *parser.NexProgram) ([]byte, error)

func (*LexerBuilder) WriteLexer

func (b *LexerBuilder) WriteLexer(program *parser.NexProgram, writer io.Writer) error
