The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. An exception will also be thrown if you use Clojure simply uses slightly different regex language that it inherited from Java, so you need to write regex as following: (str/replace (str/lower-case str1) #" (?

I do like the CL/Clojure style of macros vs.the default syntax-rules syntax-case stuff and variations in scheme. Only one element is in the set, because by-2nd treats all three of the vectors as equal. Clause question-answer syntax is like `cond`. other, e.g. This works with Clojure's hash-map, array-map, records, collections implementing java.util.Map, and values supported by the get function such as Clojure vectors, strings, and array can be keyed by their indices. It is similar to Java x.compareTo (y) except it also works for nil, and mpares numbers and collections in a type-independent manner. In general, be wary of comparing only parts of values to each other. Converts string to all lower-case. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. in the order you wish (or the reverse of that). Following is an example of upper-case in Clojure. While using W3Schools, you agree to have read and accepted our. Java comparators must return a 32-bit int type, so when a Clojure function is used as a comparator and it returns any type of number, that number is converted to an int behind the scenes using the Java method intValue. Aside: If you do not want multiple vectors in your set with the same number, by-2nd is the comparator you should use. [s] (= s (clojure. sorted-map, false otherwise (including if x and y are equal).
