And it’s precisely because we make pages this way, that code examples should do the opposite — because horizontal space is limited, but vertical space is not. If the NDC Package code is less than 11 digits (for example, a 4-4-2 structure) the code must be padded with leading zeros. Almost every code example I’ve seen uses the same basic elements — a combination of
 and  — which is a perfect choice. There’s no simple way of detecting when a line is wrapping, so the only thing we can really do is get rid of the numbers for print: Have a look at the updated demo and see how it all works in practice: There’s no particular reason why readers would want to edit code examples (unless you were making a code editor, but that’s something else entirely).

So in this article I’d like to take a hard look at code examples, to investigate the common problems they have, and try to establish some best practice for how they should be done. Copyright © 2020 LoveToKnow. Example. If you are building a library or framework that other developers will use, you need some form of API documentation.The further removed from the source code your API documentation is, the more likely it is to become outdated or inaccurate over time. For example, a programmer might say: “I wrote a lot of code this morning” or “There’s one piece of code that doesn’t work.” Code can appear in a variety of forms. But the reason for using contenteditable is to provide additional selection and navigation controls — editable code examples have significantly improved usability and accessibility. ASCII may refer to any of the following:. It starts with an explanation on the benefits of learning coding. A code … But syntax highlighting doesn’t need to be all that extensive, it only needs to be enough to improve comprehension, and the advantage of using the elements I’m suggesting is that we still get basic highlighting even without CSS. Personally, I tend towards the latter point of view. We add empty lines to code for a reason — to create logical sections and to make it more readable — and the same is true for code examples. So let’s see how our demo is improved with the addition of syntax highlighting: This is the opposite of how we treat pages as a whole, where horizontal scrolling is sorely avoided, but vertical scrolling is inevitable. The company also includes the date it was last updated and offers a downloadable PDF version. FBCI gathers examples of well-designed form-based codes from communities across the U.S. and abroad to aid research and plan making.

I will not put myself down for any reason. Code examples can have horizontal scrolling, but shouldn’t have vertical scrolling. Selections such as the Regulating Plan of Peoria, and the Building Envelope Standards of Pleasant Hill Bart Station offer a glimpse of best practices in the design and implementation of form-based codes.. You’ll notice from the CSS that I’ve chosen to use  and  instead of  and , and this choice is also debatable. Inner scrolling regions are generally not great for usability, because they’re harder to interact with, and can’t be controlled with the keyboard unless the element itself takes the focus. The container 
should also have aria-hidden, so that screenreaders won’t read the numbers; some screenreaders don’t read generated content anyway, but those that do would read them all at once and out of context, like it was one big number before the code. You can download a zipfile with all this article’s demos: James is a freelance web developer based in the UK, specialising in JavaScript application development and building accessible websites. Personally, I think hard-coding is best (since there’s no additional processing overhead), but such questions are outside the scope of this article, so I’ll leave that decision up to you. The

The point is that tabs should be tabs — how big they are is up to you. Indeed, it sometimes seems to me like that’s exactly how many sites regard their code examples, focusing on visual appearance to the detriment of their practical use. It’s very common, for example, to see tabs being converted to groups of spaces, because most browsers render tabs at 8-characters wide. Code First is really made up of a set of puzzle pieces. This example is broken down into nine sections, each with a narrative description rather than bullet points or numbering.

While a code of ethics is a set of principles distinguishing right from wrong, a code of conduct is a set of rules that guides behavior. It has to be on the inner element because that’s the one with scrolling, not to mention that putting it on the
 would allow the user to accidentally delete everything inside it! The only time that will fail is when printing the page, but for this case we can override scrolling and compensate with white-space:pre-wrap: I wouldn’t recommend the use of pre-wrap generally — because wrapping lines of code can make it much more difficult to understand — but if we don’t do that for print then the longest lines will be lost entirely. Code Examples Search by: Search. We must also define explicit white-space for the benefit of IE7 (which other browsers just inherit): We must also extend the font reset so it applies to everything inside the 
, while the overall font-size is still controlled the same way: These changes free-up the 
 to act as a positioning context for the numbers container; the container is hidden by default until an extra class is applied (and I’ll explain the reason for that in just a moment): Inside that container, we’ll create a bunch of empty , each of which have block display so they form a vertical stack, with width and padding which combine to create the 3em space we allowed for in the 
 margin-left: The numbers themselves are implemented using CSS generated content, which is preferable to normal text because they won’t be visible without CSS (whereas normal text would appear as a row of digits above the 
): But it also ties in with my general belief that generated content is not really content — because line numbers are not really content either, they’re presentation. In fact … you remember how I mentioned an extra compelling reason for using ,  and ?

To implement it, we have no choice but to wrap extra elements around bits of code, and this can be done with PHP or JavaScript, or hard-coded into the examples. A simple example of a professional code of conduct is the one shared by Dow Jones. The first thing this implies is that we definitely can’t use pre-wrap formatting, because then we wouldn’t have a fixed link between the lines of code and the numbers. The inner  provides semantic meaning and is never the wrong choice for code, although there is also a  element which can be used to show the output of a process (such as displaying a sample of HTTP headers returned by a request).

But a lot of them are not very good — because the code is badly formatted, hard to read, or can’t be copied-and-pasted without unwanted junk. However you may remember from earlier how we use white-space:pre-wrap for print, and we can’t combine that with this technique because we can’t compensate for wrapping lines. So if you’d rather use for syntax highlighting and not have these highlighting keystrokes, don’t let me persuade you otherwise. Some examples are dental for all dental-related … The purpose of code examples in technical articles and documentation can be reduced to two key premises: 1. to illustrate a concept or idea, or document the syntax of something 2. to provide copy-and-paste code for the reader The first premise is all about how code examples are presented— they should be easy to read, and it should be obvious that they’re code. For example, one section of the code of conduct is dedicated to the company’s “Dog Policy” which the company suggests is key to its unique organizational culture. Definition and Usage. The code that a programmer writes is called source code.

Users can use the compiled code, but they cannot see or modify it. The main difference between YAML and JSON is code readability. For example, a + b, printf("C program examples") are expressions and a + b; and printf("C is an easy to learn computer programming language"); are statements. We’ll start with this list, then look at each item in turn, to see how it might be achieved: I’m also going to throw in another idea, which you might not have considered before, but which actually makes a huge difference to the usability of code examples (as we’ll see): Now some of these principles might seem tricky to adhere to. It is an alphanumeric code of 16 characters. A personal code of conduct is deeply personal and relates specifically to you, the person writing it. To put it very simply, managed code is just that: code whose execution is managed by a runtime. When a programmer types a sequence of C language statements into Windows Notepad, for example, and saves the sequence as a text file, the text file is said to contain the source code. This is also why the extra styles are defined with a class selector — so they won’t apply unless the scripting is supported: The end result is perfectly-aligned numbers which don’t appear in the copied text — when you select the code, that’s all you get: Code can be selected and copied without including the line numbers. After it has been compiled, it is called object code. ActiveState Code – Popular Python recipes.

Back to our updated demo, and if you resize your window to a much smaller width, you’ll see when the horizontal scrolling kicks-in: Almost all the code examples I’ve seen which have line numbers at all, implement them by wrapping extra markup around the individual lines — either using an
      element with an
    1. for each line, or using markup like this: I think one would have great difficulty in justifying that semantically, but quite apart from that, the real problem there is that when the reader copies-and-pastes the code, its numbers are still included. And I’ve already dismissed that as a tedious and unacceptable solution! I’ve also defined some basic design and font properties, and it’s worth noting how the same core font is applied to both the
       and  elements, which is necessary to avoid browser differences (since browsers have different defaults), and then allows the overall font-size to be controlled from the 
      : When a reader copies-and-pastes from a code example, the text should have the same formatting as you would use in an ordinary editor. Firstly, we must use the inner code element as the primary layout block, applying the padding, overflow and tab-size that was previously on the
