This library provides some useful regex helpers when you have a set of regexes you need to scan across data.
In this library we call a set of regex rules ([]*regexp.Regexp) a RuleSet.
Currently there are four functions available.
func (rules RuleSet) MatchesRules(data []byte) bool {}
func (rules RuleSet) GetMatchedRules(data []byte) RuleSet {}
func (rules RuleSet) GetMatchedData(data []byte) [][]byte {}- These functions perform regex operations on byte slices
func (rules RuleSet) MatchesRulesReader(ctx context.Context, reader io.ReadCloser) bool {}
func (rules RuleSet) GetMatchedRulesReader(ctx context.Context, reader io.ReadCloser) RuleSet {}
func (rules RuleSet) GetMatchedDataReader(ctx context.Context, reader io.ReadCloser) chan Match {}- These functions perform regex operations on readers
- These functions open multiple go routines to scan the input stream concurrently against all rules
- These functions may read all data in the reader.
checkMe := ioutil.NopCloser(strings.NewReader("This is a string of text"))
// Check to make sure it matches
rules := RuleSet{
regexp.MustCompile(`random text to test for`),
regexp.MustCompile(`random text to test for two`),
regexp.MustCompile(`string o`),
regexp.MustCompile(`random text to test for three`),
}
fmt.Println(rules.GetMatchedRulesReader(context.Background(), checkMe))
// Output: [string o]
