WordPress plugins, PHPUnit, WP_Mock and a few important principles by Erik Torsner (WordPress Essentials)
Some 4500 words after I decided to add a few comments and insights ... it’s a good idea to consider what happens when follow a handful rather simple and obvious rules of how to write code.
Erik Torsner articulates his authoring of a production-ready-but-not-really WordPress plugin which reproduces the output of Matt Mullenweg’s commonplace Hello Dolly, while demonstrating and justifying his practical choices in software construction and testing; a wonderful example for others to consider and leverage.
Semantic interoperability - Wikipedia (en.wikipedia.org)
… concerned not just with the packaging of data (syntax), but the simultaneous transmission of the meaning with the data (semantics).
When elements from independent systems of semantic interoperability appear within the same document, the semantic compatibility of the independent systems is the measure of their non-interference.

HTML and CSS have very good semantic compatibility, often appearing together in the same document.

This is on my mind lately as I consider the compatibility of web application sources with microformats, while building a utility to help identify any aspects of the web application sources which interfere with the desired interoperability embodied by microformats.

I currently describe my pre-release project as: “A utility which checks webapp sources for compatibility with microformats semantics”. Based on the foregoing, I’m considering changing the description a little. At the end of the day, the work is the program that helps find the issues in the code. I’m hopeful that someone with greater comfort discussing the topic will help me to gain some confidence in how I present the program. So long as it is providing some useful and desired outcome, I’ll be working on it for awhile longer. Hopefully work to benefit more than myself!

The working title of my project is Triage. Source code is available at the link. I posted to IndieWeb chat (#wordpress) awhile back that I would publish source as soon as it does something useful. I’ve got the core command-line utility there and it will identify semantics (and syntax) issues in CSS files. It will be a little while before I have a web-based interface to make this available to a wider audience. From there I’ll look to add other languages (HTML, PHP, JavaScript).

Understanding Semantic Compatibility in Communication (acrwebsite.org)
… while attention may be paid to insuring that descriptions or attributes within a target message reflect those things most likely to be meaningful to the target receiver, very little, if any, consideration seems to go into possible interactions among those descriptions or attributes.
A brief paper which discusses the oft-unconsidered problem of semantic compatibility among attributes chosen to describe one object.
