Syncing and merging come to Bitbucket
When developing on a feature branch or a fork, your code can often get out of date. There are a number of reasons this might happen: You’re concentrating on a feature rather than syncing. You’re not yet ready to worry about integrating just yet. You’re returning to a stale branch or fork to pick up […]

Clojure from the ground up: Macros
In Chapter 1 , I asserted that the grammar of Lisp is uniform: every expression is a list, beginning with a verb, and followed by some arguments. Evaluation proceeds from left to right, and every element of the list must be evaluated before evaluating the list itself. Yet we just saw, at the end of Sequences , an…

The IDE as a value
In my last post I talked about building a game in ClojureScript using a Component-Entity-System engine and I hinted that the ideas that underly that architecture inspired how we designed Light Table . The reason why stems from the architectural goals of the project:

Introducing "Functional JavaScript"
A few years ago I got the idea that it would be fun to implement a variant of Scheme targeting the JVM. During my search for different ways to implement numerics I looked deeply at the implementation of two languages: JScheme and a little-known language Clojure . During my explorations with these two languages and the…

ClojureScript Core.async Todos
Edit: The following post is still a great way to learn about how core.async works. However, it is not a good example of how to write a web application unless you are just exploring and having fun.

Compiling to Lua
We use nginx throughout our network for front-line web serving, proxying and traffic filtering. In some cases, we've augmented the core C code of nginx with our own modules, but recently we've made a major move to using Lua in conjunction with nginx. One project that's now almost entirely written in Lua is the new…
