It is not difficult to understand the VaR, ref, agent, and atom provided by colure. The key is that you do not know where to use them? With the increase in the number of clojure codes, we have a better understanding of var. Next we will share with you that it will be a pleasure to help you understand var more quickly. Java variables are real variables. You can change them at any time and change them according to your thinking. You don't even pay att

Hacker story: How to take over the computer of Java/Clojure/Scala programmersSonatype has responded to this post and declared on their blog that the SSL link will be enabled for all users. This change makes the Java program ecosystem more secure and reliable, and I am very happy with this. Nevertheless, if you see this blog and consider spending 10 dollars to assess whether your product needs this security, the answer is no. This is like a car company

Translated from a monad tutorial for clojure programmers (Part 2) In Part1, we have learned the two most basic monad: identity monad and maybe monad. In this section, we will continue to introduce sequence monad and contact the M-result function for explanation. Finally, I will demonstrate two useful monad wildcard operators. Sequence monad (which corresponds to list monad in Haskell) is one of the most frequently used monads.

First of all, I do have to say that there are many tutorials on installing JDK 7 on Ubuntu. However, most of them are binary files based on JDK 6. If you go to the Oracle official website, you will find that all files are compressed. tar.gz. In addition, this article also provides the download link for Clojure. If you have a file name, modify it based on your actual situation! Mdash; m First of all, I do have to say that there are many tutorials on

Using existing plug-ins, it is convenient to add the gzip function to clojure.1. Add the dependency on BK/ring-gzip plug-in project. CLJ.: Dependencies [BK/ring-gzip "0.1.1"]2. Add references to the handle file.(: Use your ring.middleware.gzip])3. Add wrap-gzip to the app.(DEF app(-> (Routes app-routes)(Handler/site)(Wrap-base-URL)(Wrap-gzip ))The final compression effect is also obvious.Before compression:

In a previous e-mail, I pointed out that among the many changes, the most obvious is that the development of using other popular languages on the JVM on the Java domain has become more and more rapid. Some old and new-created JVM-based languages---JRuby and Jython, Java-style languages---Groovy and Scala and brand, new languages---Clojure and Kotlin, These languages give us a choice------get the performance and reliability of the JVM but can use a dif

Clojure is a functional language.Functional language is not the mainstream of today's development language.Most mainstream is the "imperative" language (imperative language)Among them, the object-oriented paradigm is mostly.On the trend of development, parallel, distributed, multi-CPU is becoming more and more popular.Mainstream language in the treatment of these changes is inefficient, a little powerless.Therefore, in recent years, functional languag

No matter what development environment is used, you must first familiarize yourself with the basic command line usage methods. Reference from the official site: http://clojure.org/downloads First, make sure that JDK 5 or later is installed. Then download the release package for clojure1.4: http://repo1.maven.org/maven2/org/clojure/clojure/1.4.0/clojure-1.4.0.zi

The let parameter decomposition of clojure is clearly described in this document. For example (let[[abcd:ase][1234567]][abcde])->[123(4567)[1234567]] This let can be used as a value assignment in other languages. For example, the int I = 0 in Java also supports multi-variable assignment. For example, Perl's my ($ A $ B) = @ A (I don't know if it's right, that's what it means ). However, clojure changes

Corresponding to stdin, stdout, and stderr, clojure provide three symbols by default: * In *, * out *, and * err. You can use the binding macro to perform redirection. For example, the following example redirects * out * to a file: user=> (binding [*out* (java.io.FileWriter. "/home/chenshu/tt")] (println "Write to tt.") (flush))nil Statements originally output to the console are now written to the TT file. Note that (flush) is used to write data in

In Clojure, almost everything is a value.State is the value of an identity at a point in time.For identity, four types of references are available in Clojure. Refs, making changes to the shared state in a coordinated,synchronous manner Atoms, changing the shared state in uncoordinated,synchronous mode Agents, changing the shared state in asynchronous mode Vars, manages thread local stat

A few years ago, I had time to pay attention to clojure, which focuses on lisp and its concurrent solutions. for the latter, the old hacker recommended a good article: "software transactional memory ". this article is a good starting point. On the one hand, you can learn clojure. On the other hand, you can take this opportunity to review chapter 12th of "programming language-the path to practice" and "concu

DO and block statementsIn Scala, statements enclosed in curly braces {} form a block, and its value is the value of the last statement.Scala> val a = { | println ("a") | 1}aa:int = 1{println ("a"); 1} has a value of 1.In Clojure, it is sometimes necessary to make multiple form blocks, and the value of this block is the value of the last form. Just use doUser=> (Def A (Do (println "a") 1)) a# ' user/auser=> A1 Do takes any number of fo

Symbol writing method: 1. It cannot start with a number. 2. It can be followed by text or numbers and *, + ,!, -,_,? 3./is a special character. It can only appear once in symbol. Generally, namespace is on the left. For example, my-namespace/Foo. 4 .. It is also a special character and can appear in symbol multiple times. For example, java. util. bitset. 5.: It can be used in symbol multiple times, but it cannot be continuous. 6. the symbol at the beginning or end is the symbol used by

A few days ago, I saw a blog about my thinking. In addition, I have a slight feeling of learning clojure: In the blog we read, we asked the readers to divide the cows, grass, and fish into two types. We compared two different ways of thinking: 1 ). associated thinking: Divide cows and grasses into one type, because cows graze; 2 ). object thinking: It classifies cows and fish as one type, because both are animals. Later, when preparing to learn the
