@movq@www.uninformativ.de I guess so, yes. I read something about that in some ticket. In v3 the terminfo support was dropped, though. I’m still on v2 at the moment.

And tcell seems to support my urxvt in general: https://github.com/gdamore/tcell/blob/v2/terminfo/r/rxvt/term.go#L144

@movq@www.uninformativ.de Woah, that’s really amazing progress! :-)

@movq@www.uninformativ.de Yeah, I know that terminals are super weird and messy. In both the KDE Konsole (identifying itself as TERM=xterm-256color) and xterm (TERM=xterm) it just works flawlessly. My urxvt (TERM=rxvt-unicode-256color) just doesn’t. I also tried messing with TERM in urxvt, but no luck so far.

Well, in Xterm, I actually do get key combinations with the Shift modifier. Also, combinations of several modifiers just work exactly as I expect. But not in URXvt. Hmm.

Here am I looking at the different tcell.Key constants and typing different key combinations in the terminal to see the generated tcell.EventKeys in the debug log. Until I pressed Ctrl+Alt+Backspace… :-D Yep, suddenly there went my X…

So far, it appears as if I can have either only Ctrl or Alt as modifiers. But not in combination. And Shift is just never ever set at all. Interesting.

Ha, I just stumbled across https://codeberg.org/tslocum/cbind, perfect!

@bender@twtxt.net ICQ, yeah, I vaguely remember these times, despite I still know my ICQ number like it was yesterday. :-D

@shinyoukai@neko.laidback.moe No, it’s not dead. The one account in question actually is on jabber.org.

I’m trying to implement configurable key bindings in tt. Boy, is parsing the key names into tcell.EventKeys a horrible thing. This type consists of three information:

1. maybe a predefined compound key sequence, like Ctrl+A
   
2. maybe some modifiers, such as Shift, Ctrl, etc.
   
3. maybe a rune if neither modifiers are present nor a predefined compound key exists
   

It’s hardcoded usage results in code like this:

func (t *TreeView[T]) InputHandler() func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
    return t.WrapInputHandler(func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
        switch event.Key() {
        case tcell.KeyUp:
            t.moveUp()
        case tcell.KeyDown:
            t.moveDown()
        case tcell.KeyHome:
            t.moveTop()
        case tcell.KeyEnd:
            t.moveBottom()
        case tcell.KeyCtrlE:
            t.moveScrollOffsetDown()
        case tcell.KeyCtrlY:
            t.moveScrollOffsetUp()
        case tcell.KeyTab, tcell.KeyBacktab:
            if t.finished != nil {
                t.finished(event.Key())
            }
        case tcell.KeyRune:
            if event.Modifiers() == tcell.ModNone {
                switch event.Rune() {
                case 'k':
                    t.moveUp()
                case 'j':
                    t.moveDown()
                case 'g':
                    t.moveTop()
                case 'G':
                    t.moveBottom()
                }
            }
        }
    })
}

This data structure is just awful to handle and especially initialize in my opinion. Some compound tcell.Keys are mapped to human-readable names in tcell.KeyNames. However, these names always use - to join modifiers, e.g. resulting in Ctrl-A, whereas tcell.EventKey.Name() produces +-delimited strings, e.g. Ctrl+A. Gnaarf, why this asymmetry!? O_o

I just checked k9s and they’re extending tcell.KeyNames with their own tcell.Key definitions like crazy: https://github.com/derailed/k9s/blob/master/internal/ui/key.go Then, they convert an original tcell.EventKey to tcell.Key: https://github.com/derailed/k9s/blob/b53f3091ca2d9ab963913b0d5e59376aea3f3e51/internal/ui/app.go#L287 This must be used when actually handling keyboard input: https://github.com/derailed/k9s/blob/e55083ba271eed6fc4014674890f70c5ed6c70e0/internal/ui/tree.go#L101

This seems to be much nicer to use. However, I fear this will break eventually. And it’s more fragile in general, because it’s rather easy to forget the conversion or one can get confused whether a certain key at hand is now an original tcell.Key coming from the library or an “extended” one.

I will see if I can find some other programs that provide configurable tcell key bindings.

@movq@www.uninformativ.de Sorry, I meant the builtin module:

$ python3 -m pep8 file.py
/usr/lib/python3/dist-packages/pep8.py:2123: UserWarning: 

pep8 has been renamed to pycodestyle (GitHub issue #466)
Use of the pep8 tool will be removed in a future release.
Please install and use `pycodestyle` instead.

  $ pip install pycodestyle
  $ pycodestyle ...

I can’t seem to remember the name pycodestyle for the life of me. Maybe that’s why I almost never use it.

Oh no, spam via Jabber is new for me. Fuck them!

@movq@www.uninformativ.de @prologic@twtxt.net That’s what I like about Go, too. However, every now and then I really dislike the result, e.g. when removing spaces from a column layout. Doesn’t happen often, but when it does, I hate it.

I think I should have a look at Python formatters, too. Pep8 is deprecated, I think, it’s been some time that I looked at it.

@movq@www.uninformativ.de Aha! Well, happy hacking. A tiling window manager seems to be good fun. :-)

It drizzled all morning when we picked up the old christmas trees in town with the scouts. Right after lunch the snow storm suddenly hit and dumped three centimeters of snow in just 15 minutes. I cycled home in these crazy conditions, freezing rain hammered my face. As soon as I arrived, it stopped. It’s now down to drizzling again.

All my soaked gear is now hung up to dry. The next 11 months, I’m going to find needles over needles in all kind of impossible places.

@movq@www.uninformativ.de Oh, I see. Unfortunately, there seems to be no box drawing character for a corner with a diagonal line. Indeed, this is probably the best you can do.

Is the single character enough to hit it comfortably with the mouse, though? Maybe one additional to the left and above could be something to think about. Not sure. Of course this complicates it a bit more. Personally, I like fullscreen windows, so I’m definitely the wrong guy to judge this or even comment on. :-)

@movq@www.uninformativ.de Very nice, it’s coming together!

Just in case you haven’t already noticed it, the right lower corner of the window in front was not updated when it received the focus. 8-) (In tt I also render focused text input fields with a doubly lined border, where unfocused ones have a single one.)

@bender@twtxt.net They’re not completely impossible, but C makes it much easier to run into them. I think the key point is that in those “safe” languages, buffer overflows are caught and immediately crash the program (if not handled otherwise) instead of silently corrupting memory, not being noticed right away and maybe only later crashing at a different location, where it can be very hard to find the actual root cause. This is a big improvement in my book.

Some programmers are indeed horrible. I’m guilty myself. :-)

I like the article.

@movq@www.uninformativ.de Yiha! Even autoscroll, very nice! The naming certainly drew inspiration from Urwid. I like it. Looking forward to eventually checking out its inner workings. :-)

@movq@www.uninformativ.de @prologic@twtxt.net @bender@twtxt.net Given the age, they must mean Kopernikus! https://en.wikipedia.org/wiki/DFS_Kopernikus

@movq@www.uninformativ.de :-D

@bender@twtxt.net I also went back to my duty today and fixed a problem I created right before vanishing into the holidays. Of course, I discovered more problems while fixing the one thing. Luckily, another public holiday tomorrow. :-)

During my time off, I was a very lazy rat. I planned on doing some woodworking again, but instead I started watching Itchy Boot’s Africa season: https://www.youtube.com/watch?v=pMvfS5mbsiI&list=PL8M9dV_BySaXNvQ_V1q4UU-DirPQlX0ZP

@movq@www.uninformativ.de Cool! :-) I just implemented a workaround for the time being.

@movq@www.uninformativ.de I noticed that your feed’s last modification timestamp was missing in my database. I cannot tell for certain, but I think it did work before. Turns out, your httpd now sends the Last-Modified with UTC instead of GMT. Current example:

Sat, 03 Jan 2026 06:50:20 UTC

I’m not a fan of this timestamp format at all, but according to the HTTP specification, HTTP-date must always use GMT for a timezone, nothing else: https://httpwg.org/specs/rfc9110.html#http.date

@movq@www.uninformativ.de Let’s hope they find the guys who fired that rocket onto the balcony and we actually get a fireworks ban.

@prologic@twtxt.net Very impressive! :-)

@movq@www.uninformativ.de Very nice! We also had some snow this morning, but it’s already melted. And the sun is missing, too. :-D

@movq@www.uninformativ.de Wow, that’s sick! :-)

@movq@www.uninformativ.de I’m pretty sure I know a bunch of people who love to blow up their money. :-(

Holy shit! :-O At least, the walls didn’t shake here. But we also had some very loud explosions, maybe they were far enough away. :-? Of course, the bangs continued last night.

Maybe some politicians need to be personally attacked with this sort of shit first in order to ban it once and forever.

@shinyoukai@neko.laidback.moe @prologic@twtxt.net Yeah, it’s been ages that I came across Trac. :-D

The only good thing about this absolute craziness is that I can restock my rocket sticks. I picked up twelve along the way. Unfortunately, it looks like 99.999% of ammunition is bombs instead of rockets. Some sections of my street look exactly like an arbitrary Pakistanian town that I’ve seen online.

There was surprisingly much snow in the woods. Also, all ponds have frozen over. I didn’t expect that. Not at all. There were even illegal ice skating tracks in the natural reserve. We came across a large puddle and it was at least 10cm solid ice to the ground. Crazy!

https://lyse.isobeef.org/waldspaziergang-2026-01-01/

@prologic@twtxt.net Not bad for a start, ey! Looking forward to see you going down these rabbit holes and opening one can of worms after the other. :‘-D Very, very impressive, hats off to you. :-)

@prologic@twtxt.net Can you just make them optional? :-) But that of course complicates things.

@prologic@twtxt.net That’s impressive. How large are the resulting binaries? You don’t have any optimizations in place yet, do you?

@movq@www.uninformativ.de I hid in the workshop with earmuffs for the absolute worst part.

@javivf@adn.org.es Heck yeah, let’s do this! :-) Welcome to 2026.

@shinyoukai@neko.laidback.moe We finally abandoned our GitLab. I publicly mirrored my code in the Mills Data Center a few days ago: https://git.mills.io/lyse/tt2

@movq@www.uninformativ.de Well, just a very limited subset thereof:

1. inline and multiline code blocks using single/double/triple backticks (but no code blocks with just indentation)
   
2. markdown links using using [text](url)
   
3. markdown media links using ![alt](url)
   

And that’s it. No bold, italics, lists, quotes, headlines, etc.

Just like mentions, plain URLs, markdown links and markdown media URLs are highlighted and available in the URLs View. They’re also colored differently, similarly to code segments.

I definitely should write some documentation and provide screenshots.

It totally sounds like an active warzone around here. So, I just went on a very, very, very quick stroll to check out our sunset from ontop our hill (were all the bangs are way more horrible): https://lyse.isobeef.org/abendhimmel-2025-12-31/

Hurray, I finally fixed another rendering bug in tt that was bugging me for a long time. Previously, when there were empty lines in a markdown multiline code block, the background color of the code block had not been used for the empty lines. So, this then looked as if there were actually several code blocks instead of a single one.

https://lyse.isobeef.org/tmp/tt-bugfix-empty-lines-in-multiline-code-blocks.png

@movq@www.uninformativ.de Because they’re just boxes. :-D

@movq@www.uninformativ.de Yeah, I see. Just crudely checked on my computer, with around 0.013 seconds, Python 2.7 seems a tad faster than Python 3.14’s 0.023 seconds in this little program.

The lazy imports sound not too bad, but I just skimmed over them. There are surprisingly many exceptions, but yeah, no way around them. :-)

@movq@www.uninformativ.de That’s cool! I also like the name of your library. :-) I assume you made the thing load quickly, didn’t you?

I just fixed another bug in tt where the language hint in multiline markdown code blocks had not been stripped before rendering. It just looked like it was part of the actual code, which was ugly. I now throw it away. Actually, it’s already extracted into the data model for possible future syntax highlighting.

Phew, it was just a one-time thing. Ta! :-)

Btw, @shinyoukai@neko.laidback.moe, that’s a super cool logo on your yarnd. I like it a lot!

It just doesn’t look aligned properly: https://lyse.isobeef.org/tmp/misalignment.png Could be a yarnd issue, though, it might not expect a logo this large. Just wildguessing, no idea.

@shinyoukai@neko.laidback.moe Because you might not want to commit all changed files in a single commit. I very often make use of this and create several commits. In fact, I like to git add --patch to interactively select which parts of a file go in the next commit. This happens most likely when refactoring during a feature implementation or bug fix. I couldn’t live without that anymore. :-)

If you have a much more organized way of working where this does not come up, you can just git commit --all to include all changed files in the next commit without git adding them first. But new files still have to be git added manually once.

@shinyoukai@neko.laidback.moe Do we now need ad filters in twtxt clients, too? O_o I hope not! Personally, I cannot stand the “Sent with my crappy $phone/$app” e-mail footers.

But congrats on your client. :-)

@shinyoukai@neko.laidback.moe Yeah, they don’t truly support XDG. In fact, I looked in the Go stdlib source code to notice all the differences and shortcomings.

Ok, the standard library implementation is wonky at best, at least in regards to XDG, because it really doesn’t implement it properly. https://github.com/golang/go/issues/62382 I stick to my own code then. It doesn’t properly support anything else than Linux or Unixes that use XDG, but personally, I don’t care about them anyway. And the cross-platform situation is a giant mess. Unsurprisingly.

Hmm, mine also resolves a leading tilde in these variables. And if $HOME is not specified it tries to resolve the user’s home directory by user.Current().HomeDir. Maybe that’s overkill, I have to check the XDG spec.

But I’m definitely missing os.UserDataDir(). That’s a bummer.
