Lexical differential highlighting instead of syntax highlighting
Recently there is a lot of discussion around syntax highlighting ( 1, 2, 3), which reminds me of this old post I read a while ago.
Colored Highlighter - A terminal tool to highlight specific words in your command output with colors
I needed to take a look at some live logs and quickly analyze some old ones, but I couldnβt find anything effective to highlight terms, except for esoteric sed and awk commands.
So I built ch - Colored Highlighter - a simple terminal tool to highlight specific words in your command output with colors. Perfect for tailing logs, debugging, and making command output more readable.
Try it out, all feedback is welcome!

Does anyone know of an OsmAnd rendering style that resembles OpenCycleMap? It should highlight cycle networks with vibrant colors and fade everything else. Currently, I plan bike tours by first opening OpenCycleMap on my PC to get an idea and then using OsmAnd on my phone to actually plan the tour. Ideally, I would just use OsmAnd. β Read more
What a crazy color temperature this yellow orange was in person! Sick lighting this evening: https://lyse.isobeef.org/abendhimmel-2025-09-15/

We just had some lovely colors again: https://lyse.isobeef.org/abendhimmel-2025-09-12/

@movq@www.uninformativ.de Somebody knew what he was doing, great shots! Also, quite interesting to see the color and brightness change.
@lyse@lyse.isobeef.org Very nice colors dude! π
Iβve got a prototype of my hardcopy simulator going. Iβm typing on the keyboard and the βdisplayβ goes to the printer:
https://movq.de/v/56feb53912/s.png
https://movq.de/v/235c1eabac/MVI_8810.MOV.mp4
The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see whatβs currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth β¦ itβs not ideal.
I got that idea of moving back/forth from Drew DeVault, who β as it turned out β did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)
But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. π
(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1) wrong at one point. π€ͺ And ls insisted on using colors β¦)
Surprisingly, the sky got quite some lovely colors this evening. I approve! https://lyse.isobeef.org/abendhimmel-2025-08-21/
You can explicitly use colors in manpages. I saw this in the apt manpage of Ubuntu recently, which, for some reason, uses blue text in one place:
https://movq.de/v/de5ab72016/s.png
Makes little sense to me. Iβm glad that most manpages donβt do this. I wouldnβt want unicorn vomit all over the place.
Using colors can be done using the low level commands \m and \M:
.TH foo_program 3
\m[blue]I'm blue\m[], da ba dee.
\m[red]\M[yellow]I'm red on yellow.\m[]\M[]
This is quite horrible.
@kat@yarn.girlonthemoon.xyz On the one hand, all these programs have a very long history and the technology behind manpages is actually very powerful β you can use it to write books:
https://www.troff.org/pubs.html
I have two books from that list, for example βThe UNIX programming environmentβ:
https://movq.de/v/c3dab75c97/upe.jpg
Itβs a bit older, of course, but it looks and feels like a normal book, and it uses the same tech as manpages β which I think is really cool. π
Itβs comparable to LaTeX (just harder/different to use) but much faster than LaTeX. You can also do stuff like render manpages as a PDF (man -Tpdf cp >cp.pdf) or as an HTML file (man -Thtml cp >cp.html). I think I once made slides for a talk this way.
On the other hand, traditional manpages (i.e., ones that are not written in mandoc) do not use semantic markup. They literally say, βthis text is bold, that text over here is italicsβ, and so on.
So when you run man foo, it has no other choice but to show it in black, white, bold, underline β showing it in color would be wrong, because thatβs not what the source code of that manpage says.
Colorizing them is a hack, to be honest. Youβre not meant to do this. (The devs actually broke this by accident recently. They themselves arenβt really aware that people use colors.)
If mandoc and semantic markup was more commonly used, I think it would be easier to convince the devs to add proper customizable colors.
@lyse@lyse.isobeef.org @kat@yarn.girlonthemoon.xyz Colorized manpages have been a thing for a very long time:
https://movq.de/v/81219d7f7a/s.png
Problem is, hardly anybody knows this, because you configure this by β¦ drumroll β¦ overwriting TERMCAP entries of less in your ~/.bashrc:
export LESS_TERMCAP_md=$'\e[38;5;3m' # Bold⨠export LESS_TERMCAP_me=$'\e[0m' # End Bold
export LESS_TERMCAP_us=$'\e[4;38;5;6m' # Underline⨠export LESS_TERMCAP_ue=$'\e[0m' # End Underline
export GROFF_NO_SGR=1 # Needed since groff 1.23
@movq@www.uninformativ.de @kat@yarn.girlonthemoon.xyz I also wondered for a very long time why nobody improved the man experience in the terminal. Iβd love to see links and more colors.
@lyse@lyse.isobeef.org Oh, huh, maybe it was just my GNOME 2 themes back then that didnβt show the icon. π€
I like the looks of your window manager. Thatβs using Wayland, right?
Oh, no. Itβs still X11. All my recent Wayland comments resulted from me trying to switch, but I think itβs still too early. Being unable to use QEMU (because it canβt capture the mouse pointer) is a pretty big blocker for me. This is completely broken, it just happens to be unnoticeable with modern guest OSes, so itβs probably not a priority for devs.
(Not to mention that I would have to fork and substantially extend dwl in order to βreplicateβ my X11 WM. And then, after having done that, Iβd have to follow upstream Wayland development, for which I donβt have the resources. Things would need to slow down before I can do that.)
all that wasted space of the windows not making use of the full screen!!!1
Heh. Iβve been using tiling WMs for ~15 years now, so itβs actually kind of refreshing to see something different for a change. π
Probably close to the older Windowses.
That particular theme is a ripoff of OS/2 Warp 3: https://movq.de/v/6c2a948882/s.png π
We ran some similar brownish color scheme (donβt recall its name) on Win95 or Win98

@movq@www.uninformativ.de According to this screenshot, KDE still shows good old application icons: https://upload.wikimedia.org/wikipedia/commons/9/94/KDE_Plasma_5.21_Breeze_Twilight_screenshot.png
And GNOME used to have them, too: https://upload.wikimedia.org/wikipedia/commons/9/9f/Gnome-2-22_%284%29.png
I like the looks of your window manager. Thatβs using Wayland, right? The only thing on this screenshot to critique is all that wasted space of the windows not making use of the full screen!!!1 At least the file browser. 8-)
This drives me nuts when my workmates share their screens. I really donβt get it how people can work like that. You canβt even read the whole line in the IDE or log viewer with all the expanded side bars. And then thereβs 200 pixels on the left and another 300 pixels on the right where the desktop wallpaper shows. Gnaa! Thereβs the other extreme end when somebody shares their ultra wide screen and I just have a βregularishβ 16:10 monitor and donβt see shit, because itβs resized way too tiny to fit my width. Good times. :-D
Sorry for going off on a tangent here. :-) Back to your WM: It has the right mix of being subtle and still similar to motif. Probably close to the older Windowses. My memory doesnβt serve me well, but I think they actually got it fairly good in my opinion. Your purple active window title looks killer. It just fits so well. This brown one (https://www.uninformativ.de/blog/postings/2025-07-22/0/leafpads.png) gives me also classic vibes. Awww. We ran some similar brownish color scheme (donβt recall its name) on Win95 or Win98 for some time on the family computer. I remember other people visting us not liking these colors. :-D
Folks, another unicorn vomited in our sky tonight: https://lyse.isobeef.org/abendhimmel-2025-07-19/

We covered quite some ground in the two and a half hours today. The weather was nice, mostly cloudy and just 23Β°C. Thatβs also why we decided to take a longer tour. We saw four deer in the wild, three of which I managed to just ban on film, quality could be better, though. My camera produced a hell lot of defocused photos this time. Not sure whatβs going on with the autofocus. https://lyse.isobeef.org/waldspaziergang-2025-07-10/
When the sun came out, colors were just beautiful:

@prologic@twtxt.net Yeah, this really could use a proper definition or a βmanifestβ. π Many of these ideas are not very wide spread. And I havenβt come across similar projects in all these years.

The RGB-data should be sRGB for best interoperability and not alpha-premultiplied.
(Now, I donβt know if your screen reader can work with this. Let me know if it doesnβt.)
I think these are some of the properties worth mentioning:
- The spec is extremely short. You can read this in under a minute and fully understand it. That alone is gold.
- There are no βknobsβ: Itβs just a single version, itβs not like thereβs also an 8-bit color depth version and one for 16-bit and one for extra large images and one that supports layers and so on. This makes it much easier to implement a fully compliant program.
- Despite being so simple, itβs useful. Iβve used it in various programs, like my window manager, my status bars, some toy programs like βtuxeyesβ (an Xeyes variant), or Advent of Code.
- The format does not include compression because it doesnβt need to. Just use something like bzip2 to get file sizes similar to PNG.
- It doesnβt cover every use case under the sun, but it does cover the most important ones (imho). They have discussed using something other than RGBA and decided itβs not worth the trouble.
- They refrained from adding extra baggage like metadata. It would have needlessly complicated things.
i ordered some fun colorful new minidiscs so i can finally get back to recording my mixes :D looking forward to it
