More Boot

June 17, 2016

Back in February I talked about boot-new and talked about a "future 1.0.0 release". We're not there yet, but generators got added in release 0.4.0 and, in the four minor releases since, the focus has been on refactoring to match the core Boot task structure and improving compatibility with Leiningen templates. At World Singles, we've continued to extend our usage of Boot until we have only a couple of Ant tasks left and we expect those to be within Boot's reach soon. In this post, I want to cover some of the things we've been doing with Boot recently.

I feel I should start with an apology for the "radio silence" since February -- it's a combination of work being extremely engaging (and busy!) and some aspects of my personal life going somewhat to hell in a handbasket... But things have improved lately (thankfully!) and I hope to be more regular in my blogging (I certainly have a decent queue of article ideas in my head!).

In my previous three blog posts about Boot -- Rebooting Clojure, Building On Boot, and Testing With Boot -- I looked at why World Singles decided to switch from Leiningen to Boot, as well discussing one of the missing pieces for us (testing). Once I had boot-expectations written, I was casting around for other missing pieces in the ecosystem and one glaring one was the lack of something to generate new projects from templates.

Leiningen has long-supported the generation of new projects from templates and it's pretty slick. Want to get a new Framework One application up and running?

Testing With Boot

January 31, 2016

In Building On Boot, I gave some high level benefits we'd found with Boot, compared to Leiningen, and how it had helped up streamline our build process. That article closed with a note about Boot not having the equivalent of common Leiningen plugins, and that's what I'm going to cover here, since that was the first real obstacle we encountered.

We use Jay Fields' Expectations library very heavily for most of our testing needs. We use clojure.test only for our Clojure-powered WebDriver testing. Leiningen has a test task built-in and we had been using lein-expectations for years. It was quite a shock to find out that Boot has no testing tasks built-in!

Building On Boot

January 30, 2016

In yesterday's blog post, Rebooting Clojure, I talked about our switch from Leiningen to Boot but, as Sven Richter observed in the comments, I only gave general reasons why we preferred Boot, without a list of pros and cons.

Over the coming weeks, I'll write a series of posts about some of the specifics that worked better for us, as well as some of the obstacles we had to overcome in the transition.

Rebooting Clojure

We switched from Leiningen to Boot. What is Boot and why did we switch?

Where Did 2015 Go?

January 3, 2016

I did not intend to stop blogging in 2015 but that's certainly what it looks like here!

So what kept me so busy that I didn't get around to blogging anything?

Frege (and Clojure)

February 8, 2015

I've often said that I try to follow The Pragmatic Programmer's advice to learn a new language every year. I don't always achieve it, but I try. As I've settled into Clojure as my primary language over the last several years, I've made a fair attempt to learn Python, Ruby, Racket/Scheme, Standard ML and more recently Elm. I learned that I like Python, I don't like Ruby, Racket/Scheme is "just another Lisp" (I already have Clojure) and SML is very interesting but not really widely useful these days (it's a great language for learning Functional Programming concepts tho'!). I also spent some time with Go last year (don't like it).

The Elm language is really nice - and useful for building interactive browser-based applications (and games). I've been meaning to blog about it for quite a while, and I hope to get around to that in due course. Elm is sort of inspired by Haskell, and that's really what this blog post is about. Sort of.

The Strange Loop 2014

September 25, 2014

Last week I attended The Strange Loop in St Louis. I attended in 2011 and was blown away. I missed 2012 but attended again in 2013 and was blown away once more. I already have 2015's dates in my calendar. How was 2014?

Yup, blown away again. Alex Miller and his team have created an iconic event that crosses technology boundaries and bridges between academia and industry, to bring some of the brightest minds together to share their ideas. And for attendees too, the opportunity to meet a huge variety of our peers - from novice to expert - in all different technologies, creates an atmosphere of excitement, wonder, and enjoyment.

Clojure in the Enterprise?

September 23, 2014

This was originally posted on back in April 2013 and I noticed it was recently referenced by Eric Normand in his recent blog post Convince your boss to use Clojure so I figured it was time to update the article and bring it onto my new blog.

A question was asked in early 2013 on a Clojure group on LinkedIn about reasons to migrate to Clojure for enterprise applications in a Java shop. It's a fairly typical question from people in the Java world when they hear the buzz about Clojure, and of course asking the question on a Clojure group garnered a lot of positive responses about why Clojure is a good choice. I didn't feel anyone had really addressed a core aspect of the original question which was, essentially, "Why should I, as a Java web developer, using JPA, JSF etc, choose Clojure instead for an enterprise application?". The key considerations here are "enterprise application" and "Java web devloper, using JPA, JSF etc". Clojure is rightly praised for big data projects, simplified concurrency due to immutable data, and the conciseness of its solutions. The general advice when introducing Clojure to an organization is to take a grass roots approach: use it for some tooling first, or a small low-risk (but perhaps high-profile) project and show how well it works in a Java-dominated world. Then you get more and more developers trying it out and gradually the organization adopts it for more and more projects. It's good advice, and it's often how Clojure has crept into Java shops so far (as opposed to those fast-moving small shops that already have a tendency toward polyglot development).

Powered by JavaScript

September 20, 2014

The first annual Powered by JavaScript conference, organized by Manning Books, took place in St Louis this past week. How did this inaugural event work for someone like me who really doesn't JavaScript?

I'm fairly public about my dislike of JavaScript - and it's an easy language to take pot shots at. Indeed, in the following two days of The Strange Loop conference, several speakers reminded us why JavaScript's flaws have led to so much innovation in both the compile-to-JS ("altJS") and the native JS framework space. Despite the (many) flaws, JS is ubiquitous and has evolved from a hastily constructed scripting engine to become the powerhouse of the modern web and with Node.js has moved into the server side development space and as a common part of a build chain that touches almost every web development shop, regardless of their core technology.
