For most of the 90’s and the beginning of the aughts, I was the CTO of a small training and consulting company. When I went to work there, our primary platform was Clipper, which was a rapid-application tool for building DOS applications atop dBASE files. Clipper was object-based, and could be made fully object-oriented with an extension library. We had an advantage over our competitors because we built an extensive object-oriented framework for cranking out applications. We were happy as clams: we had both a thriving training and consulting business.
In this part two of the series we’ll learn how to use traits to implement the decorator pattern. Decorator is a popular “GOF Pattern” that’s implemented well in the JDK IO API. Scala traits remove quite a bit of ceremony from the implementation of this pattern. In addition to the benefits of traits we saw in part 1 of this series, in this part we’ll see the advantages of applying multiple traits both at the class and instance level.
Domain Specific Languages (DSLs) are often littered with the accidental complexity of the host language. Have you ever seen a supposedly "friendly" language expression like "ride(minutes(10)).on(bus).towards(Basel)"? The newest version of Groovy contains a language feature that aims to eliminate the noise of all those extra periods and parenthesis so that your DSL looks more like "ride 10.minutes on bus towards Basel". This article shows you, step-by-step, how to use Groovy Command Expressions and plain old metaprogramming to write just this DSL, and also offers advice on when, and when not, to use this new language feature.
First, let me take this opportunity to thank you for your continued support of No Fluff Just Stuff. The emphasis of this magazine is all about quality content just like our software conference series. For those of you not familiar with the No Fluff Just Stuff Symposium series let me share a little history. I started NFJS in 2002 to offer high quality technical content in a conference format and offered in over 30 cities throughout the U.S. and Canada. The credo of NFJS is simply: Local Venue, World Class Conference. NFJS offers individuals the opportunity to attend an outstanding conference right in your own backyard whether you live in Milwaukee, or Denver, just to name a few. The NFJS conference series is focused on great technical content(stuff) and little to no fluff - advertising, vendors, etc...
NFJS, the Magazine is an eclectic mix of articles centered on software development and all that entails. Whether you are a developer, architect or manager, you should find all of the articles in NFJS interesting and enlightening. All of the article authors are speakers on the No Fluff Just Stuff Tour and published thereby insuring a great read. We want this magazine to be time efficient for the reader. To me, NFJS the Magazine is all about outstanding content that is easily consumable. The other great thing about the format of this magazine is that you can easily read articles out of sequence over the months and refer back to something anytime. Unlike traditional magazines, NFJS has a much longer shelf life and makes a great reference source.
We are very excited to bring you NFJS, the Magazine ten times a year. I hope you find NFJS, the Magazine to be a great informational resource. Drop me an email and let me know your thoughts.
