> Why do Go articles so often have no syntax highlighting? Rob Pike, one of the 3 original Go architects, has stated in the past he doesn’t like syntax highlighting [1]. > Syntax highlighting is juvenile. When I was a child, I was taught arithmetic using colored rods (http://en.wikipedia.org/wiki/Cuisenaire_rods http://en.wikipedia.org/wiki/Cuisenaire_rods). I grew up and today I use monochromatic numerals. — Rob Pike Maybe Sergey Kamardin, the author of this article, is following Rob Pike’s philosophy. That being said, the website has references to a Go library called Chroma [2] which purpose is to colorize source code. The library borrows ideas from a popular JavaScript library called “highlight.js” [3] and that is why you can also see “highlight” CSS classes. The website downloads this CSS file [4] which contains a couple of instructions to make the code look the way it looks. The official Go Blog has popularized this type of design [5] and many Go programmers has adopted it in their own websites.

FYI Chroma is based on Pygments, not highlightjs.

That is very bizarre

  Go is very opinionated in a lot of bizarre ways.

    Well, he has a point. If you need a variable to be colored to know it's a variable, then I'd argue that you don't really know what you're doing. If you don't need a variable to be colored to know it's a variable, then why do you color them? A counter argument would be that you have this huge visual cortex in your brain which can use cues like this to help you quickly find what you're looking for. A counter argument to that would be that you should know your code well enough to not need to rely on anything like that. When I started programming, I had notepad and that was it. I didn't need colors. I use colors now, though. What's that say? I have no idea.

      Not everything you do is about need. I think highlighting helps reduce some of the cognitive load involved in mentally parsing a code block. Especially in a language you might be unfamiliar with. I also happen to like the way it looks.

Go philosophy is to optimize for the brain, to lower cognitive load. This statement is in absurd opposition to this philosophy. No need for benchmarcks to know that a developper is less productive and more error prone without semantic highlighting.

  Yeah everyone "knows" this, but where's the proof? I've never seen any proof that syntax highlighting helps someone who knows their code well. Things that are supposed to be common knowledge like this often turn out to be false when someone eventually decides to challenge their assumptions. I programmed for a full decade with Notepad alone. I don't think colored keywords are important, though I use syntax highlighting today.

    There are probably tasks you can perform quicker when you're accustomed to syntax coloring, since the brain tends to capitalize on association with easily detected features. Finding the start of a function could be such as task, but the gain would be low (a few 100s of milliseconds, I'd guess). At the same time, it might slow down other tasks, which can be harder to identify. I was just changing some html template, and I made a dumb "extra quote"" error because of highlighting. It probably took me more than a minute, which would offset a great number of small speedups. I guess the conclusive proof won't be easy to find.

    Why would I know whatever code I'm reading well? Most of the time I'm reading code it's unfamiliar to me, like for instance library code, picking up a project after a long break, or in this case on a blog.
