Go是否具有不区分大小写的字符串contains（）函数？

Question

I'd like to be able to determine whether stringB is a case-insensitive substring of stringA. Looking through Go's strings pkg, the closest I can get is strings.Contains(strings.ToLower(stringA), strings.ToLower(stringB). Is there a less wordy alternative that I'm not seeing?

Answer 1

If it's just the wordiness that you dislike, then how about making your code formatting cleaner, e.g.:

strings.Contains(
    strings.ToLower(stringA),
    strings.ToLower(stringB),
)

Or hiding it in a function in your own utils (or whatever) package:

package utils

import "strings"

func ContainsI(a string, b string){
    return strings.Contains(
        strings.ToLower(a),
        strings.ToLower(b),
    )
}
