Types ¶
type Token ¶
Token is a token struct
func (Token) IncrementIndentLevel ¶
IncrementIndentLevel is a placeholder implementing Reindenter interface
func (Token) IsJoinStart ¶
IsJoinStart determines if ttype is included in TokenTypesOfJoinMaker
func (Token) IsKeyWordInSelect ¶
IsKeyWordInSelect returns true if token is a keyword in select group
func (Token) IsLimitClauseStart ¶
IsLimitClauseStart determines ttype is included in TokenTypesOfLimitClause
func (Token) IsNeedNewLineBefore ¶
IsNeedNewLineBefore returns true if token needs new line before written in buffer
func (Token) IsTieClauseStart ¶
IsTieClauseStart determines if ttype is included in TokenTypesOfTieClause
type TokenType ¶
type TokenType int
TokenType is an alias type that represents a kind of token
const ( EOF TokenType = 1 + iota // eof WS // white space NEWLINE FUNCTION COMMA STARTPARENTHESIS ENDPARENTHESIS STARTBRACKET ENDBRACKET STARTBRACE ENDBRACE TYPE IDENT // field or table name STRING // values surrounded with single quotes SELECT FROM WHERE CASE ORDER BY AS JOIN LEFT RIGHT INNER OUTER ON WHEN END GROUP DESC ASC LIMIT AND ANDGROUP OR ORGROUP IN IS NOT NULL DISTINCT LIKE BETWEEN UNION ALL HAVING OVER EXISTS UPDATE SET RETURNING DELETE INSERT INTO DO VALUES FOR THEN ELSE DISTINCTROW FILTER WITHIN COLLATE INTERVAL INTERSECT EXCEPT OFFSET FETCH FIRST ROWS USING OVERLAPS NATURAL CROSS TIME ZONE NULLS LAST AT LOCK WITH QUOTEAREA SURROUNDING )
