Clojure vs Haskell
gist.md Haskell vs Clojure The JSON data is in the following format { "Genesis": { "1": { "1": "In the beginning..." , "2": "..." }, "2": { ... } }, "Exodus": { ... }, ... } In JSON, keys aren't ordered and must be strings. The goal is to parse the JSON file, order everything correctly (which means parsing the keys into integers), and produce an array that looks like this: [ ("Genesis", 1, 1, "In
A Few Tips for Writing Macros in Clojure - Altometrics Blog
Abstract Macros are powerful metaprogramming tools, but they can be difficult to use well. In this article, I share several tips for creating correct, legible, and useful macros in Clojure. Introduction Macros, in the Lisp sense, are in many ways the ultimate metaprogramming tool. In Lisp, not only is the parse tree explicit in the source code (which is the point of the parentheses), but the code
Clojure, The Good Parts
I kid, somewhat. This title is of course based on Douglas Crockford's seminal work, Javascript, The Good Parts , which demonstrated that Javascript isn't a terrible language, if only you avoid the icky parts. This is my heavily opinionated guide to what a "good" production Clojure app looks like in 2016. I love Clojure, I've been using it pretty much exclusively since 2009. In the 7 years I've bee
Clojure 1.7 is now available
We are pleased to announce the release of Clojure 1.7. The two headline features for 1.7 are transducers and reader conditionals. Also see the complete list of all changes since Clojure 1.6 for more details. Transducers Transducers are composable algorithmic transformations. They are independent from the context of their input and output sources and specify only the essence of the transformation i
Gradual typing for Clojure
Today’s programming landscape is dynamic and polyglot. Interlanguage interoperability is a mainstay — it’s almost unavoidable that a given piece of code will be used without the knowledge of the original author. So it’s surprising to learn most static type systems completely ignore the pragmatics of running statically typed code in the real world. Who can use this code? Can they break the type inv
Clojure by Example
About This Page I don't like reading thick O'Reilly books when I start learning new programming languages. Rather, I like starting by writing small and dirty code. If you take this approach, having many simple code examples are extremely helpful because I can find answers to these questions very easily. How can I define a function? What's the syntax for if and else? Does the language support strin
Clojure における幾つかの実践的なデバッグ方法 - (define -ayalog '())
まえがき だいたい 2 週間くらい Clojure を書いているとライブラリのバグを綺麗に踏み抜いたりマクロの沼に引きずりこまれたりと、まぁやたらとデバッグする機会があります。それで先日からライブラリを clone して書きなおして lein install して…などしていたのですが、一緒に Clojure 書いている Clojure ﾁｮｯﾄﾃﾞｷﾙ人に「そんなことしなくてもいいよ」と色々教えてもらったのでだいたい現時点で僕が知っている幾つかのデバッグ方法を書いておこうと思う。ただし、これは Clojure 一般というよりは Emacs/Cider-mode という環境に依存している部分が多いと思うので他の環境を使っている人はもしかしたらかなり役に立たないかもしれません。アプローチそのものは他の IDE などでも実装されているかもしれませんが僕はよく知らないので悪しからず。 Print
Clojure · How I Start.
We are going to explore Clojure by creating a fun project together. In particular, we will create a twitter bot that creates its text based on a mashup of Edward Lear’s poetry, and a goodly selection of functional programming text taken from Wikipedia. Why Edward Lear and Functional Programming? First, because I really enjoy his poetry. I fondly remember reading his poetry to my children. Some of
Post: Pixie: stunningly good
A sweet Clojure-ish language It's likely no secret that I really dig Clojure. It's the first unityped language I've used since Objective-C in the early 90s that I really like. Yes, I still love Scala, but I think Clojure is pretty much the best designed computer language I've ever used... and maybe that's because Clojure is mostly "less is more" but in a few places, it's not. The things I really l
Visualizing Twitter Connections with D3 and ClojureScript | Will Fleming’s Software blog
Introduction I was curious about the connections between some of the people I follow on Twitter and wanted to try visualizing it using D3 and ClojureScript using a force directed graph. The end result looks like this: Not a lot of surprises, there are a few clusters around common interests: Emacs, food, Dwarf Fortress, Hadoop, etc. Code In this post i’ll just share a minimum of ClojureScript code,
cloxp
Programming Clojure, Smalltalk-style This is the first post about a system I call cloxp, a development environment for Clojure that facilitates interactivity and exploration. In the following I want to explain the motivation of the project. Apart from this introduction I plan two more posts, one explaining some of the features of cloxp and one describing change handling and persistency. Please not
