Functions

func IsMatch

func IsMatch(pattern string, src []byte) bool

IsMatch checks whether given bytes <src> matches <pattern>.

正则表达式是否匹配

func IsMatchString

func IsMatchString(pattern string, src string) bool

IsMatchString checks whether given string <src> matches <pattern>.

判断给定的字符串<src>是否满足正则表达式<pattern>.

func Match

func Match(pattern string, src []byte) ([][]byte, error)

MatchString return bytes slice that matched <pattern>.

正则匹配，并返回匹配的列表(参数[]byte)

func MatchAll

func MatchAll(pattern string, src []byte) ([][][]byte, error)

MatchAll return all bytes slices that matched <pattern>.

正则匹配，并返回所有匹配的列表(参数[]string)

func MatchAllString

func MatchAllString(pattern string, src string) ([][]string, error)

MatchAllString return all strings that matched <pattern>.

正则匹配，并返回所有匹配的列表(参数[][]string).

func MatchString

func MatchString(pattern string, src string) ([]string, error)

MatchString return strings that matched <pattern>.

正则匹配，并返回匹配的列表(参数[]string)

func Quote

func Quote(s string) string

Quote quotes <s> by replacing special chars in <s> to match the rules of regular expression pattern. And returns the copy.

转移正则规则字符串，例如：Quote(`[foo]`) 返回 `\[foo\]`

func Replace

func Replace(pattern string, replace, src []byte) ([]byte, error)

ReplaceString replace all matched <pattern> in bytes <src> with bytes <replace>.

正则替换(全部替换).

func ReplaceFunc

func ReplaceFunc(pattern string, src []byte, replaceFunc func(b []byte) []byte) ([]byte, error)

ReplaceFunc replace all matched <pattern> in bytes <src> with custom replacement function <replaceFunc>.

正则替换(全部替换)，给定自定义替换方法

func ReplaceString

func ReplaceString(pattern, replace, src string) (string, error)

ReplaceString replace all matched <pattern> in string <src> with string <replace>.

正则替换(全部替换)，字符串

func ReplaceStringFunc

func ReplaceStringFunc(pattern string, src string, replaceFunc func(s string) string) (string, error)

ReplaceStringFunc replace all matched <pattern> in string <src> with custom replacement function <replaceFunc>.

正则替换(全部替换)，给定自定义替换方法

func Split

func Split(pattern string, src string) []string

Split slices s into substrings separated by the expression and returns a slice of the substrings between those expression matches.

通过一个正则表达式分隔字符串.

func Validate

func Validate(pattern string) error

Validate checks whether given regular expression pattern <pattern> valid.

校验所给定的正则表达式是否符合规范
