Functions ¶
func IsFirst ¶
IsFirst is a tool function that returns whether the byte is an alphabet or an underline
func IsLetter ¶
IsLetter is a tool function that returns whether the byte is an alphabet or an underline or a digit
func IsLower ¶
IsLower is a tool function that returns whether the byte is an alphabet in lower case
func IsUpper ¶
IsUpper is a tool function that returns whether the byte is an alphabet in upper case
func ParseExponent ¶
ParseExponent parses the exponent part of a float
func ParseFloat ¶
ParseFloat parses the input to a float
func ParseFraction ¶
ParseFraction parses the fraction part of a float
Types ¶
type Pattern ¶
type Pattern struct {
// contains filtered or unexported fields
}
Pattern defines all the lexical rules rule describes the rule by an actual function str defines the key word directly
type Scanner ¶
type Scanner struct {
// contains filtered or unexported fields
}
Scanner defines a lexical analyzer ptn is the lexical rule tkn is the raw code to be analyze skp decides whether to skip space
