Functions

func Is

func Is(typeMask uint32, c rune) bool

Is checks if a rune meets specified typeMask or not.

func IsCSymbol

func IsCSymbol(str string) bool

IsCSymbol checks specified string meets a C symbol or not.

func IsType

func IsType(typeMask uint32, str string) bool

IsType checks if all runes of a string meet specified typeMask or not.

func IsTypeEx

func IsTypeEx(typeFirst, typeNext uint32, str string) bool

IsTypeEx checks if the first rune of a string meets typeFirst, and the other runes meet typeNext.

func IsXmlSymbol

func IsXmlSymbol(str string) bool

IsXmlSymbol checks specified string meets a XML symbol or not.

func ScanCSymbol

func ScanCSymbol(str string) int

ScanCSymbol skips a C symbol and returns its end position. If the string does not start with a C symbol, it returns 0. If there are no other characters after the C symbol, it returns -1.

func ScanType

func ScanType(typeMask uint32, str string) int

ScanType scans a string to find a rune that doesn't meet specified typeMask. if not found, it returns -1.

func ScanTypeEx

func ScanTypeEx(typeFirst, typeNext uint32, str string) int

func ScanXmlSymbol

func ScanXmlSymbol(str string) int

ScanXmlSymbol skips a XML symbol and returns its end position. If the string does not start with a XML symbol, it returns 0. If there are no other characters after the XML symbol, it returns -1.

func SkipCSymbol

func SkipCSymbol(str string) string

SkipCSymbol scans a string to skip a C symbol. If the string doesn't start with a C symbol, it returns the origin string.

func SkipTypeEx

func SkipTypeEx(typeFirst, typeNext uint32, str string) string

func SkipXmlSymbol

func SkipXmlSymbol(str string) string

SkipXmlSymbol scans a string to skip a XML symbol. If the string doesn't start with a XML symbol, it returns the origin string.
