Functions

func EndsInSemicolon

func EndsInSemicolon(spl string) bool

EndsInSemicolon returns true if the last lexical token is a semicolon.

func LastLexicalToken

func LastLexicalToken(spl string) (lastTok int, ok bool)

LastLexicalToken returns the last lexical token. If the string has no lexical tokens, returns 0 and ok=false.

func Parse

func Parse(spl string) (*tree.Select, error)

func SplitFirstStatement

func SplitFirstStatement(spl string) (pos int, ok bool)

SplitFirstStatement returns the length of the prefix of the string up to and including the first semicolon that separates statements. If there is no semicolon, returns ok=false.

Types

type Parser

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

type TokenString

type TokenString struct {
	TokenID int32
	Str     string
}

TokenString is the unit value returned by Tokens.

func Tokens

func Tokens(spl string) (tokens []TokenString, ok bool)

Tokens decomposes the input into lexical tokens.
