Variables

var AllowedExperimental = map[string]struct{}{
	"ranges": {},
}

AllowedExperimental contains keywords for which the EXPERIMENTAL_ or TESTING_ prefixes are allowed to be parsed along with the keyword to the same token. This ambiguity exists during the deprecation period of an EXPERIMENTAL_ keyword as it is being transitioned to the normal version. Once the transition is done, the keyword should be removed from here as well.

var KeywordNames = []string{}/* 539 elements not displayed */

KeywordNames contains all keywords sorted, so that pg_get_keywords returns deterministic results.

var KeywordsCategories = map[string]string{}/* 539 elements not displayed */

Functions

func EncodeEscapedSQLIdent

func EncodeEscapedSQLIdent(buf *bytes.Buffer, s string)

EncodeEscapedSQLIdent writes the identifier in s to buf. The identifier is always quoted. Double quotes inside the identifier are escaped.

func EncodeRestrictedSQLIdent

func EncodeRestrictedSQLIdent(buf *bytes.Buffer, s string, flags EncodeFlags)

EncodeRestrictedSQLIdent writes the identifier in s to buf. The identifier is quoted if either the flags ask for it, the identifier contains special characters, or the identifier is a reserved SQL keyword.

func EncodeSQLBytes

func EncodeSQLBytes(buf *bytes.Buffer, in string)

EncodeSQLBytes encodes the SQL byte array in 'in' to buf, to a format suitable for re-scanning. We don't use a straightforward hex encoding here with x'...' because the result would be less compact. We are trading a little more time during the encoding to have a little less bytes on the wire.

func EncodeSQLBytesInner

func EncodeSQLBytesInner(buf *bytes.Buffer, in string)

EncodeSQLBytesInner is like EncodeSQLBytes but does not include the outer quote delimiter and the 'b' prefix.

func EncodeSQLString

func EncodeSQLString(buf *bytes.Buffer, in string)

EncodeSQLString writes a string literal to buf. All unicode and non-printable characters are escaped.

func EncodeSQLStringWithFlags

func EncodeSQLStringWithFlags(buf *bytes.Buffer, in string, flags EncodeFlags)

EncodeSQLStringWithFlags writes a string literal to buf. All unicode and non-printable characters are escaped. flags controls the output format: if encodeBareString is set, the output string will not be wrapped in quotes if the strings contains no special characters.

func EncodeUnrestrictedSQLIdent

func EncodeUnrestrictedSQLIdent(buf *bytes.Buffer, s string, flags EncodeFlags)

EncodeUnrestrictedSQLIdent writes the identifier in s to buf. The identifier is only quoted if the flags don't tell otherwise and the identifier contains special characters.

func EscapeSQLString

func EscapeSQLString(in string) string

EscapeSQLString returns an escaped SQL representation of the given string. This is suitable for safely producing a SQL string valid for input to the parser.

func GetKeywordID

func GetKeywordID(k string) int32

GetKeywordID returns the lex id of the SQL keyword k or IDENT if k is not a keyword.

func IsBareIdentifier

func IsBareIdentifier(s string) bool

IsBareIdentifier returns true if the input string is a permissible bare SQL identifier.

func IsDigit

func IsDigit(ch int) bool

IsDigit returns true if the character is between 0 and 9.

func IsHexDigit

func IsHexDigit(ch int) bool

IsHexDigit returns true if the character is a valid hexadecimal digit.

func IsIdentMiddle

func IsIdentMiddle(ch int) bool

IsIdentMiddle returns true if the character is valid inside an identifier.

func IsIdentStart

func IsIdentStart(ch int) bool

IsIdentStart returns true if the character is valid at the start of an identifier.

func NormalizeName

func NormalizeName(n string) string

NormalizeName normalizes to lowercase and Unicode Normalization Form C (NFC).

func NormalizeString

func NormalizeString(s string) string

NormalizeString normalizes to Unicode Normalization Form C (NFC). This function is specifically for double quoted identifiers.

Types

type EncodeFlags

type EncodeFlags int

EncodeFlags influence the formatting of strings and identifiers.

const (
	// EncNoFlags indicates nothing special should happen while encoding.
	EncNoFlags EncodeFlags = 0

	// EncBareStrings indicates that strings will be rendered without
	// wrapping quotes if they contain no special characters.
	EncBareStrings EncodeFlags = 1 << iota

	// EncBareIdentifiers indicates that identifiers will be rendered
	// without wrapping quotes.
	EncBareIdentifiers

	// EncFirstFreeFlagBit needs to remain unused; it is used as base
	// bit offset for tree.FmtFlags.
	EncFirstFreeFlagBit
)

func (EncodeFlags) HasFlags

func (f EncodeFlags) HasFlags(subset EncodeFlags) bool

HasFlags tests whether the given flags are set.
