It got darker

By pure coincidence, it's six years ago tomorrow that I finally, after years of running Emacs with a bright white background, moved to using a dark theme. It took a little bit of getting used to but eventually I got very comfortable with it, and since then have run everything I can in a dark mode too.

On occasion, in the last year or so, I've had this urge to move to something darker. Also, in part, it's an urge to change things up a little. I felt it was time for a refresh of how my Emacs looks. I've tried a few themes, but none have ever stuck. When trying them I've run into various issues:

• It just didn't look nice at all
• Too many other things I use in Emacs didn't get themed
• It looked like there was going to be too much work to do to really theme things well
• It caused Emacs to crash¹

However, yesterday evening, after making an effort to simplify my mode line, I was determined to find a darker theme that I would be happy with. I think I finally managed!

I've settled on modus-vivendi from modus themes. Out of the box it felt right, and from what I can see in the documentation there's an amazing amount of customisation you can do. The key point there too is the documentation; there's so much of it, it's incredibly comprehensive.

For example: the default choice for the mode line is to have an unsubtle border around it -- presumably to create a good contrast. I found that far too distracting and was wondering what I could do about it. I didn't have to wonder long, the documentation addresses exactly that situation.

Another downside I ran into is that the colours that were showing in the mode line, when I switched to mood-line yesterday, were gone. I spent a short amount of time last night, and a good hour or so this morning, trying to wrangle mood-line into something I liked, but I just couldn't get anything sensible going. Eventually I cracked, fired up Antigravity, prompted it with:

I am using mood-line for my mode line -- see init.d/packages.d/melpa/mood-line.el and https://github.com/emacsmirror/mood-line

I am using https://protesilaos.com/emacs/modus-themes as my theme

I would like to have finer control over the parts of the mode line I've configured. For example, I'd like the buffer name to stand out in an informative colour, but one that is part of the modus theme's colour scheme.

Don't make changes yet, but help me understand how I should do this in a maintainable way.

and then spent about 20 minutes going back and forth, refining what I wanted; this got me a result I'm happy with from a visual point of view. I still need to fully review the code and the approach it took, but it isn't too far removed from what I'd been trying myself.

Overall I'm pleased with the result, and this is the longest I've stuck with a new theme (at this point I'm probably about 4 or 5 hours into working in it). I think that says something significant. I can see myself still wanting to tweak some aspects of it though. For example, the left-hand fringe doesn't feel quite right, in a way I can't quite put my finger on. While I want it to stand out from the main editing area, it feels... disconnected in some way. Also the background colour of the mode line still feels like it doesn't quite blend how I'd like.

Now to see if this lasts...
