Mark is currently the tech lead for the BBC News Frameworks team; the author of Pro Vim (published by Apress) and Programming in Clojure (self published with LeanPub)
Mark's technical interests are wide and varied: *nix tools, Clojure, Go, Rust, JRuby and functional programming. Along with promoting solid object-oriented principles, microservices architecture, AWS services and distributed/concurrent systems design.
Outside of the tech world Mark plays guitar, practices a myriad of martial arts (jiu-jitsu, ishinryu karate and kickboxing) and is a pretty mean ballroom dancer.
Most web developers use a build tool of some sort nowadays. I’m not refering to continuous integration software like Jenkins CI (a very popular build system), but the lower-level software it uses to actually acquire dependencies and construct your applications with.
There is a dizzying array of options to choose from: Apache Ant (XML-based), Rake (Ruby-based), Grunt (JS-based), Gulp (JS-based), Broccoli (JS-based), NPM (JS-based), Good ol’ shell scripts (although no real orchestration around it). The build tool I want to look at in more detail here though is the granddaddy of them all: Make.
Ruby is a great language. It was designed to foster happiness and productivity in developers, all the while providing tools that are effective and yet focused on simplicity.
One of the tools available to the Rubyist is the RubyGems package manager. It enables us both to include “gems” (i.e. packaged code) that we can reuse in our own applications and to package our own code as a gem to share with the Ruby community. We’ll be focusing on the latter in this article.
In this article, we’ll go over the concepts and techniques required to build a command line tool using Node.js and PhantomJS. Building a command line tool enables you to automate a process that would otherwise take a lot longer.
Command line tools are built in a myriad of languages, but the one we’ll focus on is Node.js. For those short on time, I’ve condensed the core process into three steps. This is the secret sauce to convert your Node.js script into a fully functioning command line tool. But do stick around to see what else I have to show you.
