Working with white space

Description

Collection: Drupal 7 Development Core Concepts
Chapter: Overview of Coding Standards

Transcript

let's go ahead and move on to the next comment. This is about white space so white space includes any space characters, any tab characters, and any new line characters. The deal with white space is that we want to make sure that we don't have any extra white space in our file.

The purpose for this is that when you think about how many modules there are that exist in the Drupal code repository, if every one has extraneous white spaces, that can actually amount to a lot of space in the end. So we want to make sure that we don't have any unnecessary white space. The necessary white space should definitely be there.

It for code readability. But white space at the end of lines or at the end of files should be removed. So, this, if you look at this file in your editor and you turn on the "view whitespace" in Komodo, this is under "view", and then there's an option to view white space.

You'll see that there's some extra characters here at the end of the lines and on new lines that don't have any code on them at all or any comments, and these should all be removed. Now, that's easier said than done. Especially if you have a lot of code to go through so what you can do is, in most editors, they offer a regex ...

Skill focus: Drupal Development
Skill level: Beginner - Advanced

This series contains over 160 videos and 14 hours of content, covering the most essential aspects of Drupal development, from setting up module scaffolding to working with forms and the database to working with jQuery and JavaScript. This library is a must-have for all developers.

We have merged the Working With Files and the File API series with this one. You can now find the file-related videos in the final chapters of this series.

Before watching this series, you will need a fresh Drupal 7 installation. Follow the videos in the Setting Up a Web Environment With Drupal to get Drupal set up on your Windows, OSX (Mac) or Linux machine.

Some of the key points we'll be covering include:

  1. How to work with the most important Drupal APIs
  2. How to use hooks to modify virtually anything
  3. How to create and modify forms using the Form API
  4. How to apply coding standards to your work
  5. How to work programmatically with users and nodes
  6. How to work with jQuery and JavaScript in Drupal
  7. How to work with files and the File API

Who this video collection is for

This collection is for anyone who wants to learn how to program for Drupal 7. You may find yourself wanting to adjust Drupal in some ways that are impossible to do with existing modules, and the only way to really get it done is through creating a module of your own. This collection gives you the skills to do just that. It is also a good overview of jQuery, which can be useful outside of the context of Drupal.

Prerequisites

Having a basic understanding of PHP will be useful. If you're coming to the table without much coding experience, consider watching the PHP Programming Basics collection first.
