Clojure provides command line tools that can be used to start a Clojure repl, use Clojure and Java libraries, and start Clojure programs. See the changelog for version information. After following these installation instructions, you should be able to use the clj or clojure command to start a Clojure repl.
Clojure is a homoiconic language, which is a fancy term describing the fact that Clojure programs are represented by Clojure data structures. This is a very important difference between Clojure (and Common Lisp) and most other programming languages - Clojure is defined in terms of the evaluation of data structures and not in terms of the syntax of character streams/files.
Clojure CLR. This project is a native implementation of Clojure on the Common Language Runtime (CLR), the execution engine of Microsoft’s .Net Framework. ClojureCLR is programmed in C# (and Clojure itself) and makes use of Microsoft’s Dynamic Language Runtime (DLR).
In Clojure, however, everything is an expression! Everything returns a value, and a block of multiple expressions returns the last value. Expressions that exclusively perform side-effects return nil.

Clojure provides a set of alternative math operators suffixed with an apostrophe: +', -', *', inc', and dec'. These operators auto-promote to BigInt upon overflow, but are less efficient than the regular math operators. Ratio. Represents a ratio between integers. Division of integers that can’t be reduced to an integer yields a ratio, i.e. 22 ...
Put simply, Clojure implemented atop Rust! My main goals here are. Project Goals: To create a version of Clojure that gets to exist independent of a particular platform; To explore a Clojure that, being more independent, has a. Proper tail call elimination b. Conditions / Restarts c. Any other feature it might not normally be able to indulge
Clojure was created by Rich Hickey and is developed by a core team of developers at Cognitect, which supports this work.The Clojure development team values a measured and thoughtful approach to language evolution with a strong emphasis on maintaining backward compatibility.
Clojure supports the use of type hints to assist the compiler in avoiding reflection in performance-critical areas of code. Normally, one should avoid the use of type hints until there is a known performance bottleneck. Type hints are metadata tags placed on symbols or expressions that are consumed by the compiler. They can be placed on ...
Clojure’s = is true when comparing immutable values that represent the same value, or when comparing mutable objects that are the identical object. As a convenience, = also returns true when used to compare Java collections against each other, or against Clojure’s immutable collections, if their contents are equal. However, there are important caveats if you use non-Clojure collections.

clojure.core Available since 1.0 (and) (and x) (and x & next) Evaluates exprs one at a time, from left to right. If a form returns logical false (nil or false), and returns that value and doesn't evaluate any of the other expressions, otherwise it returns the value of the last expr. (and) returns true.
Evaluates the expressions in order and returns the value of the last. If no expressions are supplied, returns nil. See http://clojure.org/special_forms for more ...
Clojure is a concise, powerful, and performant general-purpose programming language that runs on the JVM, CLR, Node.js, and modern mobile and desktop web browsers. New to Clojure and not sure where to start? Here are a few good resources to get you off on the right foot: Rich Hickey's Greatest Hits (videos) Clojure for the Brave and True
Practicalli Clojure takes a hands on approach to learning to code with Clojure. The REPL is the Clojure interactive environment used to create an run all code. You will quickly get a feel for Clojure by evaluating, breaking, fixing and extending code in the REPL, all the while getting instant feedback on what your code is doing.
All Clojure and Clojure contrib jars are signed when they are uploaded to the Maven Central repo. A typical url in Maven Central will look something like:

Clojure is not the product of traditional research and (as may be evident) writing a paper for this setting was a different and challenging exercise. I hope the paper provides some insight into why Clojure is the way it is and the process and people behind its creation and development.

Clojure is a dynamic, general-purpose programming language. It combines the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming and the performance gains of compiling and running on the JVM. It is a lisp dialect that runs on the JVM, enabling the use of Java code side by side with Clojure.
