What about syntax highlighting?

I built a colorscheme for Vim [0] that is close to monochrome when I was worried about blue light (I've since had kids and now this kind of worry doesn't rate at all), and I basically use bold and highlights (I hate underlining, italics, and squiggles, but I think you can do all that too in the GUI version). I found it surprisingly usable.

> in the GUI version

or in the TUI version, in a terminal like Kitty.

I want to try some monochrome UI, but that amber is definitely not my taste. Let me see if there is a "paper-like" theme, or maybe I can make one myself.

I (re)built it w/ a little script I call roygvim [0] -- here's the source [1]

Thanks for sharing! Would it be alright if I try it out during our livestream this week?

Yes sure. public domain.

Hi Alex. If you are interested in showing VSCode, here are the theme and additional color settings that I use with my Mira Pro:

https://gist.github.com/RossBencina/f37f51c3f53796f0988c7d96...

Possibly not the best syntax highlighting, but generally makes the UI legible.

Feel free to use.

You have the option of a few greyscale levels, bold, pehaps italic, and depending on font maybe extra-bold and light. That should be enough for the essentials, though it will feel like a downgrade if you have got used to a richly colourful environment and rely on it for reasons other than liking it being pretty.

I don't require it myself but that's a concern, it's nice to have. Maybe someone can build an editor that uses different fonts within one file instead of different colors. Could be something out there for color blind folks already, though seeing no colors at all is unusual. But e-ink has grayscales so you could at least make comments a bit lighter, I think I'd be happy with that.

There's plenty of options available. A coworker of mine used to print out code for reviews. You can use italic, bold and underline as alternative to colors. Grayscale might work nicely for eInk too - for laser printers just thin/regular/bold probably works better.

Other fonts... I could see myself being distracted by changing fonts in a document, except maybe for comment blocks. But for those italic/thin seems to work well already.

Tried to find the tool... it's GNU enscript. Syntax highlighting for several languages, outputs to postscript.

I like your idea better.

I didn’t know about GNU Enscript, going to check it out. Thanks!

I'd do 3 greys, from lightest to darkest: comments, syntactical cruft like braces, semicolons, certain keywords, etc., and then 'actual' code, variable names and so on.

Much more variation than that with 256 colours is mostly just making it pretty rather than offering helpful distinction imo.

That indeed would be my issue with it for programming.

this is not the same technology as e-ink, hence why they call it e-paper

It’s an electrophoretic display, in the category of e-paper, informally called e-ink, made by the company E Ink.
