Add the following dependency to your project.clj file:

[superstring "3.2.1"]

It's also annoying to pull in $library as well as clojure.string to get complete coverage. Or pull in $library where the functions in clojure.string are renamed, or re-implemented with slightly different semantics. I've opted to alias all the vars in clojure.string so you only need to require a single namespace and because I know you hate surprises.

A ton of functions, either on String, or elsewhere, return true as the truthy value. In a lisp this is a terrible waste. To afford string punning this library returns s as the truthy value so you can do stuff like this:

(require '[superstring.core :as str])

(some-> linkedIn-profile
        (str/includes? "developer" :ignore-case)
        (str/includes-all? ["java" "xml"] :ignore-case)
        (str/includes-any? ["ninja" "rockstar"] :ignore-case)
        extract-contact-info
        send-unsolicited-job-offer!)

The character ß is a lower case, german, character that is shorthand for ss. This character is, to my knowledge, exceptional in that it upper cases to a combination of two characters. Frankly, this annoying character should be deprecated, but in the meanwhile we should try to treat it in a consistent manner.

The jvm has the following behavior:

(Character/toUppercase \ß) ;;=> \ß
(.toUppercase "ß") ;;=> "SS"
(.equalsIgnoreCase "ß" "ss") ;;=> false

I'm interpreting this to mean:

1. String comparisons ignoring case should not treat ß and ss or SS as equal.
2. Any string operations which change the case should consider SS to be the upper case variant of ß.

Yes!
