3 Things Java Programmers Can Steal from Clojure

Sat 09 Mar 2013 03:38:24 PM CST

Many of the cool parts of Clojure are written in Java. That means you can access those parts from any Java code. Just include the Clojure JAR, import the classes, and you've got better tools.

Clojure is Imperative

Fri 22 Aug 2014 11:51:19 PM CDT

Clojure is an imperative language. Its operations are defined in terms of concrete actions. But those actions are often the same actions available to the programmer at runtime. This makes it easy to bootstrap.

Clojure Test Directory

Mon 30 Mar 2015 10:55:57 PM EDT

Where to put your tests is a common question. You could put them anywhere, but you want to pick a place that makes it easy to find, easy to exclude from production, and work well with your tools. My recommendation is to follow what most projects do, which takes care of all of these requirements.

Complex Syntax

Tue 19 Aug 2014 09:48:13 AM CDT

Lisps are revered for their simple syntax, but parens are complex. They complect function calls and macro calls, which have drastically different semantics.

The conj Mental Bump

Mon 23 Mar 2015 11:18:42 PM CDT

conj can be confusing if you're used to other languages. It is not a commonly defined operation. Most languages define common positional adding operations. conj, however, has more useful semantics. How do you use conj usefully if you can't guarantee the position?

core.async Code Style

Tue 10 Jun 2014 11:03:57 PM CDT

If your functions return `core.async` channels instead of taking callbacks, you encourage them to be used within `go` blocks. Unchecked, this encouragement could proliferate your use of `go` blocks unnecessarily. There are some coding conventions that can minimize this problem.

Conveyor Belts: Nature's core.async Channels

Thu 13 Nov 2014 01:25:18 PM CST

Conveyor belts are strikingly similar to Clojure core.async channels. While it could be a coincidence, there is speculation that conveyor belts were influenced by a deep understanding of core.async.

Data-First Programming

Fri 27 Feb 2015 05:08:54 PM CST

If something is important, you should deal with it sooner and more often. That's the approach Clojure takes to data representations. It means serialization of internal data is a non-issue.

Data > Functions > Macros. But why?

Tue 23 Dec 2014 11:29:44 PM CST

"Prefer data over functions" is a common adage in Clojure circles. It is poorly debated because it is a terse statement in generalities. A valuable perspective is that data is transparent at runtime, while functions are not. This perspective gives a firm ground for discussion and design.

4 Features Javascript can steal from Clojure(Script)

Wed 17 Sep 2014 11:52:22 AM CDT

ClojureScript adds a lot of value on top of the Javascript platform. But some of that value can be had directly in Javascript without using a new language.

JSON Serialization for APIs in Clojure

Thu 10 Jul 2014 10:42:08 PM CDT

Ring 1.3

Tue 22 Jul 2014 11:53:00 PM CDT

Ring is great because it closely models the HTTP message format using native Clojure data structures. It strictly defines a message format that any software can use and rely on. With Ring 1.3, the specification has gotten even closer to the HTTP spec.
