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.
