The Google Chrome User Agent

As the new Google web browser was released last night (I'm writing this post using the new browser) I thought it would be good to update our readers on the user agent string that this web browser has.

The user agent of any browser can be found out by using the userAgent property of the navigator object. This is available in most modern browsers and is thankfully also present in Google Chrome.

navigator.userAgent

As an example the user agent for FireFox 3 on a Windows XP machine looks like this.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

Using the same code, and the same machine, the user agent produced by Google Chrome is as follows.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13

So detecting it should only be a case of looking for the word "chrome". Just like this:

var ischrome = navigator.userAgent.indexOf("Chrome")? true : false;

If you want to see what the user agent is on your machine then paste this code into a web page and hit refresh. It is quite a basic bit of code and should work in most browsers.

<span id="useragent"></span>
<script type="text/javascript">
document.getElementById('useragent').innerHTML = navigator.userAgent;
</script>

user

JavaScript

Using Shadow DOM

When I first heard the term "Shadow DOM" I had to laugh at the name. I had visions of a cloak and dagger HTML element that would only be seen on the dark web. Or some sort of nefarious shadow site that was the after effect of a hack. In reality, this is quite a useful bit of technology that has a number of applications, although it does need a fairly modern browser to be able to use it. Shadow DOM is part of the web components strategy, which includes custom elements and HTML templates. These give developers the power to create custom tools and experiences that are encapsulated away from other parts of the code. In this article I will go though what the shadow DOM is, how to use it, and in what situations it comes in handy.

Simple Horizontal Segmented Bar Chart With CSS

Bar charts are powerful ways to show the relationships between different data items. If the data you want to show is discrete then a simple horizontal segmented bar chart is a good idea. You can easily change a collection of numbers into a related set of attributes.

Inspecting And Reusing jQuery Events

Adding events to HTML elements with jQuery is pretty simple, but I found that extending those events wasn't an easy task. I was faced with an issue where I had some third party code that performed an action on an element, and I needed to add an event and call the same handler from that event. As this was within a CMS I had limited scope to just add my new event to the existing code, so I needed a way of pulling out the current jQuery events and then calling that event handler separately. This post looks at how I accomplished this.

Keychron K2 Wireless Mechanical Keyboard: A Review

I (like a lot of other people) recently started to work at home a lot more, and with a permanent desk setup at home I wanted a decent keyboard to work with. My work machine is a MacBook Pro 2018 and I dislike the keyboard quite a lot. It feels 'poppy', has some interesting key placements (the up and down arrows in particular), has no escape key or function keys at all.

Grep Context

Grep is a really powerful tool for finding things in files. I often use it to scan for plugins in the Drupal codebase or to scan through a CSV or log file for data.

For example, to scan for user centric ViewsFilter plugins in the Drupal core directory use this command (assuming you are relative to the core directory).

grep "@ViewsFilter(\"user" -r core

The -r flag here recursively scans the 'core' directory. This command returns the following output.

Langton's Ant In JavaScript

After looking at Conway's game of life I have been looking at other forms of cellular automata. This lead me to discover Langton's ant, which is a different kind of cellular automata where an agent (namely an ant) is used to turn the squares on or off as it travels around a grid.

The rules of Langton's ant are quite simple. The ant simply follows two rules as it moves around the grid.
