Functions

func Parse

func Parse(in io.Reader) (commands []interface{}, err error)

Types

type Error

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

Error provides information about errors that occurred during parsing or execution.

func (Error) Column

func (e Error) Column() int

Column returns the column number in which the error occurred.

func (Error) Error

func (e Error) Error() string

func (Error) Line

func (e Error) Line() int

Line returns the line number in which the error occurred.

func (Error) Message

func (e Error) Message() string

Message returns a description of the error that occurred.

type GroupBySpec

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

type Lexer

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

func NewLexer

func NewLexer(in io.Reader) *Lexer

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 (l *Lexer) Error(s string)

func (*Lexer) Lex

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

Lex runs the lexer. Always returns 0. When the -s option is given, this function is not generated; instead, the NN_FUN macro runs the lexer.

func (*Lexer) Line

func (yylex *Lexer) Line() int

Line returns the current line number. The first line is 0.

func (*Lexer) Stop

func (yyLex *Lexer) Stop()

func (*Lexer) Text

func (yylex *Lexer) Text() string

Text returns the matched text.
