clojure syntax

Learn Clojure - Syntax - Clojure Evaluation The Reader produces Clojure data. The Clojure compiler then produces the bytecode for the JVM. The unit of source code is a Clojure expression, not a Clojure source file. Source files are read as a series of expressions, just as if you typed those expressions interactively at the REPL.

Cheatsheet - map namespace syntax e.g. #:foo{:a 1} is equal to {:foo/a 1}. ##, (1.9) symbolic values: ##Inf ##-Inf ##NaN. $, JavaContainerClass$InnerClass.

The Reader - One might say the reader has syntax defined in terms of characters, and the Clojure language has syntax defined in terms of symbols, lists, vectors, maps etc.

So yeah, about Clojure's syntax - Clojure's syntax is simple enough that most of it can be described in a blog post. If you're accustomed to C-lineage languages, this syntax may

A Concise Guide to Clojure - As in Lisp, code and data have the same syntax. Clojure has a lot more syntactic sugar than Lisp, which makes it more complex to learn but easier to read.

Images for clojure syntax - Let's use this interactive shell to look at some of the syntax and functions we've just learnt about. Let's start by opening

Just Enough Clojure - let is a Clojure special form, a fundamental building block of the language. ;; ;; In addition to parameters passed to functions, let provides a way to create ;; lexical

clojure pass list as arguments

Passing list of variables individually to clojure function - You are looking for apply . This calls a function with the arguments supplied in a sequence. But are you aware that there's a function interleave

apply - clojure.core - Applies fn f to the argument list formed by prepending intervening arguments to /treat-clojure-macro-as-a-function (defmacro make-fn [m] `(fn [& args#] (eval

On Clojure arguments - A function should accepts at least five arguments. You will refactor . This way of passing a map is widely-spreaded across Clojure libraries. It even (defn foo [& args] ;; args is a list) (foo 1 2 3 4) ;; args is (1 2 3 4). Starting

Learn Clojure - Functions - We invoke these functions by passing the appropriate number of arguments: The variable arguments must occur at the end of the argument list. They will be

Keyword Arguments in Clojure, the Right Way – Digital Digressions - In the future, Clojure may have destructuring support for this style. flexible, because we can construct the argument map elsewhere and then pass it to the function: (defn foo [{:keys [a b]}] (list a b)) (foo {:a 5, :b 6}) ;;=> (5 6).

Clojure Don'ts: Optional Arguments with Varargs – Digital - Another Clojure don't today. This one is a personal style preference, but I'll try to back it up. Say you want to define a function with a mix of

Parameter Lists in Common Lisp and Clojure « null program - A lambda list can specify optional parameters, optionally with default arguments, named (keyword) parameters, and whether or not the function

Functions in Clojure | Clojure Documentation - Without the use of a variadic argument list, you would have to call the function with a single map

Do Things: A Clojure Crash Course - Vectors aren't the only way to store sequences; Clojure also has lists. .. The values you pass to functions are called arguments, and the arguments can be of

Keyword Arguments - Ruby, Python, Clojure - Ruby will check if you pass an unknown parameter: is used in the argument list , the argument will contain all unknown keyword arguments as

clojure map

map - clojure.core - Collections will be consumed ;; and passed to the mapping function in ([:a :d :g] [:b :e :h] [:c :f :i]) ;; From http://clojure-examples.appspot.com/clojure.core/map.

Map? - Maps are represented as alternating keys and values surrounded by { and } . When Clojure prints a map at the REPL, it will put `,'s between each key/value pair.

Map-indexed - Keywords implement IFn for invoke() of one argument (a map) with an optional second argument (a default value). For example (:mykey my-hash-map :none)

Learn Clojure - Hashed Collections - Create sorted, sorted-map sorted-map-by (clojure.data.avl/) update update-in ( clojure.set/) rename-keys map-invert GitHub: Medley.

Data Structures - In other words, elisp uses two different, data structure–specific functions to implement the map operation, but Clojure uses only one. You can also call reduce on a map in Clojure, whereas elisp doesn't provide a function for reducing a hash map.

Cheatsheet - Clojure Maps - Learn Clojure in simple and easy steps starting from basic to advanced concepts with examples including Overview, Environment, Basic Syntax,

Core Functions in Depth - Here is a fairly typical way to transform a map. zipmap takes a list of keys and a list of values and "does the right thing" producing a new Clojure

Clojure Maps - We can map over a collection of words and increment them by writing an anonymous function. (map (fn [animal] (str animal "s")) ["pig" "cow" "goat" "cat" " dog"

Mapping a function on the values of a map in Clojure - In general, the only major difference between Clojure maps and maps/hashes/ dictionaries in some other languages is that Clojure maps are

clojure cond

cond - clojure.core - Takes a set of test/expr pairs. It evaluates each test one at a time. If a test returns logical true, cond evaluates and returns the value of the corresponding expr and

Cond-> - The cond macro works like the way the if conditional does branching. Unlike if , cond can take multiple tests and corresponding clauses. Since Clojure doesn't

Cond->> - Clojure offers another evaluation statement called the ‘cond’ statement. If a test returns logical true, ‘cond’ evaluates and returns the value of the corresponding expression and doesn't evaluate any of the other tests or expressions. There is also a default statement, which gets

Conditional cond - Clojure has lots of operators for dealing with conditional statements: if, cond, condp, case and when. The expression is evaluated, if it is true the “then” part is executed and result returned otherwise the “else” part is run and returned. In Clojure if on false and nil return

Clojure If, cond, case - This is the first part of a multi-part series I want to start titled “Understanding Clojure”. Often times I come across Clojure code that can be refactored a bit better or

walmartlabs/cond-let: A useful merge of cond and let - Clojure's cond-> (and cond->> ) is a versatile macro. It isn't a new macro, it has been around since version 1.5, but I finally discovered and

Understanding Clojure: cond and condp - cond. cond is a series of tests and expressions. Each test is evaluated in order and the expression is evaluated and returned for the first true test. (let [x 5] (cond

The usefulness of Clojure's cond-> - Cond and friends. #clojure. There are a number of different cond's in Clojure. Now cond short circuits - it will stop at the first true expression. You may think
