The test-constants need not be all of the same type. they are all the same. The function < is a perfect example, as long as you only need to compare numbers. 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. Hello and hello will be treated as equal strings. What's the difference between a power rail and a signal line? src/jvm/clojure/lang/AFunction.java I have this code to replace all store's name is ABC (or Abc ) to XYZ. And in macros the old one is quite useful at times. The file name extension is case-insensitive. Using Kolmogorov complexity to measure difficulty of problems? The StringComparer returned by the CurrentCultureIgnoreCase property can be used when strings are linguistically relevant but their case is not. a positive int value if the first argument is to be treated as greater than the second, and 0 if they are equal. At first glance, pattern-matching expressions look like the familiar case statements from your favorite C-like language. Returns true if x equals y, false if not. Following is an example of upper-case in Clojure. Find centralized, trusted content and collaborate around the technologies you use most. It takes a string and makes whatever Clojure data structures it can from that string. sorting on values like maps or records. Here we describe the default sorting order provided by the function compare. clojure.string/upper-case Converts string to all upper-case. (i.e. But in Clojure, it can't use the regex /abc/i with i flag for ignore case sensitive like other languages. This function is format-tolerant and reads incomplete dates, for example, only a year. This is because compare does not put What am I doing wrong here in the PlotLegends specification? Not the answer you're looking for? Compare equal-length Clojure vectors containing "sort keys" in order to do a multi-field comparison Return Value Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. x comes before y, positive if x comes after y, or 0 if they are equal. str1.casecmp (str2) == 0 "Apple" .casecmp ( "APPLE") == 0 #=> true Alternatively, you can convert both strings to lower case ( str.downcase) and compare for equality. The concatenation of strings can be done by the simple str function. Here is the syntax of this method . Overall the solution feels a bit hacky. false otherwise (including if x and y are equal).

For example, \u03A9 is the literal for . A file extension name is 1 or more characters without white space, follow by dot. The techniques described in "Multi-field comparators" above provide correct comparators for this example. Returns a negative number, zero, or a positive number when x is logically 'less than', 'equal to', or 'greater than' y. As a toy example, you might have a collection of vectors, each with two elements, parts of keys in a sorted collection. It can be a 3-way comparator returning Could be historical accident though.

In our case, a vector of one or three dates wont pass it. Asking for help, clarification, or responding to other answers. Use the == operator with the [ [ command for pattern matching. See the "decorate-sort-undecorate" technique described in the documentation for This method takes two strings as the first and the second parameters and a length as the last parameter. works well for sorting numbers in increasing order, or strings, keywords, or symbols, As explained later, it should not behave like <= for numbers You can define you own functions named < > etc. The consent submitted will only be used for data processing originating from this website. It supports Clojure 1.5.1 and later as well as ClojureScript. It is less error-prone to use explicit conditional checks and return -1, 0, or 1, or to use boolean comparators. This method returns one integer value. Is there a solutiuon to add special characters from software and how to do it, Theoretically Correct vs Practical Notation.

Some information relates to prerelease product that may be substantially modified before its released. First we will show a way to do it that does not compare vectors. The :require class does a few things here. The compareToIgnoreCase () method compares two strings lexicographically, ignoring lower case and upper case differences. It returns 0 if two strings are equal, case-insensitively. Splits string on a regular expression. Below is how you can do case-insensitive string comparison using localeCompare(): The localeCompare() function is particularly useful if you want to sort an array of strings, ignoring case: You may be tempted to compare two strings using regular expressions and JavaScript regexp's i flag. Many of the fractions would be equal to each the default comparator. In Bash, how can I check if a string begins with some value? Equality. A common thought in such a case is to use a boolean comparator function based on <= instead of <: The boolean comparator by-2nd-<= seems to work correctly on the first step of creating the set, This function works only on null terminated strings. it can compare integers, longs, and doubles to each Each of the It will cause sorted collections to behave incorrectly, and sorting to give unpredictable The built-in Clojure function compare is a 3-way comparator for many kinds of values, including strings, but it compares characters by their UTF-16 Unicode code points, which for the ASCII subset will compare upper-case letters differently than lower-case letters, so maybe not what you are looking for. True if both strings are equal ignoring the character case and False, if both are not equal. (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 #.
