How do I convert a string to a lower case representation?

sudo gem install jekyll bundler

I feel that there must be built-in function for it, but I just can't find it.

cd ~/Sites

I did find a ToLower in "unicode/letter", but it only works for one rune at a time.

Yes there is, check the strings package.

package main


import (
"fmt"
"strings"
)


func main() {
fmt.Println(strings.ToLower("Gopher"))
}

If you need to handle a Unicode Special Case like Azeri or Turkish, you can use ToLowerSpecial:

strings.ToLowerSpecial(unicode.TurkishCase, "Hello, WoRLd") // => "hello, world"
