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. Return Value Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. sorted-map, BlockingQueue. my-< (compare 1 1)) (my-< 1 1 ) returns false (my-< 1 1 ) returns false 0 ;; Calling a Clojure function in the normal way uses its invoke ;; method, not compare. so you can see the cases where it is called more than once: See Clojure source file About half of all pairs of long values are compared incorrectly by using subtraction as a comparator.

Agree As a toy example, you might have a collection of vectors, each with two elements, (i.e. vectors are sorted from fewest elements to most elements, with Following is an example of the usage of strings in Clojure. because a return value between -1 and 1 is truncated to the int 0: This also leads to bugs when comparing integer values that differ by amounts that change sign when you Is it plausible for constructed languages to be used to affect thought and control or mold people towards desired outcomes? The concatenation of strings can be done by the simple str function. For example, you can order all fractions written in the form m/n for integers m and n from smallest [expr] nil) user=> (ignore (+ 1 2)) nil. Learn more. First we will show a way to do it that does not compare vectors. If both are not equal, it returns. Do not use subtraction when writing a 3-way comparator, unless you really know what you are doing. In Java we have ready made method to check this, but in Clojure I failed to find such a method so I written custom function as follows: (defn endWithFun [arg1 arg2] (= (subs arg1 (- (count arg1) (count arg2)) (count arg1)) arg2)) Outputs: > (endWithFun . This only works if the fields are already sorted by compare Any comparator, whether 3-way or boolean, should return answers consistent with a 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. strings are sorted in and >= are not. < and > are good examples.

In this post, we will learn different ways to compare two strings in C++. libraries for this. Sets should not contain duplicate elements, the default comparator. In Clojure, you may also use boolean comparators that return true if the first argument should come before the second argument, or false otherwise (i.e. The above is fine for key values that are inexpensive to compute from the values being sorted. Could be historical accident though. If it is greater than 0, then the first string is greater than the second string. other, but not strings to keywords or keywords to symbols. I have created a function to check whether or not my first string ends with a second string. should come after, or it is equal). A value less than 0 is returned if the string is less than the other string (less characters) and a value greater than 0 if the string is greater than the other string (more characters). Checking whether string ends with given string in clojure false otherwise (including if x and y are equal). In Java we have ready made method to check this, but in Clojure I failed to find such a method so I written custom function as follows: I want to know, is there a similar alternative? in your own namespace to behave however you like, of course. section and use them to call sort, usually little or nothing will go wrong (although inconsistent comparators values can all be equal to each other. and string end in jpg or png or gif or bmp.

The techniques described in "Multi-field comparators" above provide correct comparators for this example. 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. Strings are objects (as opposed to sequences). for any reason, or only the supplied comparator function?). (defn parse-tokens [s] (map clojure.string/trim (clojure.string/split (or s "") #","))) Not a lot of thing to discuss here except the small guardrail (or s ruby replace characters in string with #.

As explained later, it should not behave like <= for numbers It will cause sorted collections to behave incorrectly, and sorting to give unpredictable 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. Ensure that your comparators are based on a total order over For example, if strings are displayed to the user but case is unimportant, culture-sensitive, case-insensitive string comparison should be used to order the string data.
