A fun blog post from Alice Pellerin – if you can color code source code, why not try that for hex data?

This pairs nicely with a previous post on Unsung in that it too actively investigates what makes for useful, not just “pretty” color coding.

Among many genuinely useful deeplinks you can use to control Raycast from afar in a simple way, I just spotted an interesting one:

raycast://confetti

This is what it does:

Despite it being a confetti cannon and nothing more, I think it goes deeper than stuff like e.g. Asana’s “celebration creatures”, and it deserves recognition for three actually kinda serious reasons:

• You can use it to quickly test whether you’re wiring deeplinks correctly. It’s clever the Raycast team put it at the beginning of the doc page; I think every API or a complex connection method should have a simple and delightful “success scenario” for two reasons: to celebrate you establishing that connection, and to have something so simple it cannot itself be misbehaving (this way you know that if you can’t get confetti to work, you for sure messed up something elsewhere).
• Once you know how to invoke it from far away, it’s also great for testing other things. Sounds can be muted. In JavaScript, console.log() can be too buried if you don’t have a console open or visible, and alert(“Test”) is kind of depressingly old-school and steals focus. This HUD-like thing feels like a modern way of approaching this: You know you’ll notice it when it fires away, and it will leave no lasting damage. (Okay, fair, it does steal focus too, so that’d be one thing to improve.)
• It has great production value. I hate perhaps all of Google’s search easter eggs because they’re built so extremely cheaply – try searching for “do a barrel roll” or “askew” (and no, I’m not going to dignify them with links because links are my love language). It’s rare and worth celebrating when something that could very well be an internal joke or a test feature for nerds is actually something you want to use because it’s so well-made. (See also: Linear’s internal testing UI.)

I was reminded of and rewatched this 43-minute 2016 talk by David Jonathan Ross with great interest:

Ross designed Input, a coding font superfamily which was very inspiring to me in the day, and taught me that coding fonts could be a place of surprising creativity and innovation.

First of all, Input has four width options: from regular through Narrow to Condensed to Compressed – this not only allows to avoid the “blocky/​squareish” nature of many coding fonts, but also, pragmatically, to squeeze in more stuff on mobile screens.

Secondly, since a lot of coding environments didn’t (and maybe still don’t) allow for fine-tuned typography settings, you can bake them into a font upon download – choose a different default line height to be there in the font itself, or have your favorite style of zero just hanging there in the default slot.

Thirdly, serif versions of Input coexist with sans serif, and so does italic, and you can mix them together.

But most important thing comes at the end: you can imagine coding in non-monospaced fonts! What seemed like blasphemy before made so much sense once I put it to use – I still code in Input Sans Narrow (non monospaced) to this day:

Of course, since the release of Input in 2014 a few other coding fonts did interesting creative things in this (mono)space. But to me this will always be the original that opened my eyes to what’s possible, and the talk captures so well a lot of deep thinking that went into the font. To quote Ross:

Type design is design and design is about solving problems.

I was just looking at some old 1980s screenshots and wondering “why don’t you ever see syntax highlighting in inverse video”? And then I randomly stumbled upon this deep dive into syntax highlighting from Nikita Prokopov.

I don’t know if I disagree with everything here, but there’s a lot of great stuff in there, and a lot of food for thought.

Highlighting everything is like assigning “top priority” to every task in Linear. It only works if most of the tasks have lesser priorities.

I thought the mention that comments should be visually promoted, not demoted, was particularly insightful.

Also, the idea that light themes are not popular because the colors are duller… this is very interesting. It could be so interesting to try a light theme with very prominent chiefly at the periphery of Display P3.

I have never been very invested in syntax highlighting because I find the UI to change it in text editors is usually pretty harrowing, but now I’m interested.
