This has to be something simple, but I've been pulling my hair out for days. I have made two regexp.MustCompile where one is just a simple punctuation search and the other is a combination of an identifier plus the punctuation search. I am building the patterns with two strings that I concatinate as argument to the MustCompile.
The complex Find works, but the simplier one returns nothing. This is the opposite of what I expected. Playground: https://go.dev/play/p/4gp43BvwRwo The code is near trivial, The output in the playground shows an empty slice when Find is called on the punctuation, yet returns the expected slice on the more complex pattern: output: >< Heart - Program exited. Source: package main import ( "fmt" "regexp" ) func main() { var fn = []byte("Heart - Crazy On You") const nameP = "(([0-9A-Za-z]*)\\s*)*" const divP = "-*" var regMulti = regexp.MustCompile(nameP + divP) var regPunch = regexp.MustCompile(divP) p := regPunch.Find(fn) fmt.Printf(">%s<\n", p) m := regMulti.Find(fn) fmt.Printf("%s\n", m) } Any enlightenment would be greatly appreciated. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
