Hell yeah, @kat@yarn.girlonthemoon.xyz is back! \o/

Hurray, I can now press gg instead of g to go to the top in tt. Much better! :-) Other multi-key combinations are also easily possible now.

I should probably write a real article about this at some point, but here we go. The only downside with my new key binding system is that it breaks tview’s established pattern. You’ve got an InputHandler(), that is implemented using WrapInputHandler(…). It typically then directly implements the switching logic depending on the key press. Something like this:

func (w *Widget) InputHandler() func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
    // WrapInputHandler allows for intercepting key events with SetInputCapture(…)
    // from the outside for customization. This handles the default key bindings.
    return t.WrapInputHandler(func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
        switch event.Key() {
        case tcell.KeyRune:
            if event.Modifiers() == tcell.ModNone {
                switch event.Rune() {
                case 'k':
                    w.scrollUp()
                    return // we already handled the event, stop processing

                case 'j':
                    w.scrollDown()
                    return
                }
            }
        }

        // We didn't handle the key event. Maybe the parent
        // widget knows what to do with it.
        if handler := w.parent.InputHandler(); handler != nil {
            handler(event, setFocus)
        }
    })
}

From the outside, you can intercept and either stop or continue the widget’s original key handling with a potentially rewritten key event using SetInputCapture(…):

w := NewWidget()
// customized or additional key bindings
w.SetInputCapture(func(event *tcell.EventKey) *tcell.EventKey {
    switch event.Key() {
    case tcell.KeyUp:
        // Rewrite the event, so the "cursor up" key is an alias
        // for the vim key binding "k", that is handled by the
        // wrapped input handler above. (I know, I know, this is a
        // completely unrealistic example, why would anyone use
        // cursor keys when there are vim key bindings available?!)
        return tcell.NewEventKey(tcell.KeyRune, 'k', tcell.ModNone)

    case tcell.KeyRune:
        if event.Modifiers() == tcell.ModNone {
            switch event.Rune() {
                case 'q':
                    app.Stop()
                    // we already handled the event, do not pass it
                    // to the wrapped input handler above
                    return nil

                case 'r':
                    toggleMessageReadStatus()
                    return nil
            }
        }
    }

    // we didn't handle the event, pass it to the wrapped
    // input handler above
    return event
}

Since they all expect a single key, I’ve noticed that using multiple dedicated KeyBindings of mine on these different levels kinda breaks multi-key handling with common prefixes. The outer-most KeyBinding captures the prefix, but it can’t transfer it to the inner one if not handled by the outer one. At least not without some more (potentially ugly) changes. So, I now have to work with just a single KeyBindings object for the entire widget chain (if it consists of multiple other widgets or the regular input handler and input capture are in the game). The outside needs to register all its key bind customizations or extensions at the same level that the original widget handles its default ones. Doable by exposing the widget’s KeyBindings instance, but not pretty. You always have to keep this in mind.

With the KeyBindings, it will look like that:

type Widget struct {
    parent tview.Primitive

    // make it available to children or the outside either by
    // direct field access or by providing a getter method
    KeyBindings *bind.KeyBindings
}

func NewWidget() *Widget {
    w := &Widget{KeyBindings: &bind.KeyBindings{}}
    w.KeyBindings. // default key bindings
        Bind0(bind.KeySequence('k', w.scrollUp).
        Bind0(bind.KeySequence('j', w.scrollDown)
    return w
}

func (w *Widget) InputHandler() InputHandler() func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
    return t.WrapInputHandler(func(event *tcell.EventKey, setFocus func(p tview.Primitive)) {
        // also note the missing support for focus transfer at the moment
        event = w.KeyBindings.Capture(event)
        if event == nil {
            return
        }

        if handler := w.parent.InputHandler(); handler != nil {
            handler(event, setFocus)
        }
    }
}

And then from the outside, or in a child widget:

w := NewWidget()
w.KeyBindings. // additional or customized key bindings
    Bind1(bind.KeySequence(tcell.KeyUp), func(*tcell.EventKey) *tcell.EventKey {
        return tcell.NewEventKey(tcell.KeyRune, 'k', tcell.ModNone)
    }).
    Bind0(bind.KeySequence('q'), app.Stop).
    Bind0(bind.KeySequence('r'), toggleMessageReadStatus)

When directly working with tview primitives that are not part of custom widget implementations, the following works well so far:

textView := tview.NewTextView().
    SetWordWrap(true).
    SetText("…")
    SetScrollable(true)
textView.SetInputCapture((&bind.KeyBindings{}).
    Bind0(bind.KeySequence('q'), app.Stop).
    Bind1(bind.KeySequence('g', 'g'), func(*tcell.EventKey) *tcell.EventKey {
        return tcell.NewEventKey(tcell.KeyHome, 0, tcell.ModNone)
    }).
    Capture)

I need to sleep on this some more.

Also, writing very long messages like this one is really not all that fun in tt’s editor. I should absolutely provide a way to shell out to vim.

(Took me about one and a half hours to compose, holy crap. But not only because of not using vim. Although, that might have saved me a quarter hour or so for sure. Proof-reading this message also uncovered quite a few bugs in my real documentation. So, that’s a big win!) Good night!

@david@daiwei.me Not so keen on the mowing part. :-)

@prologic@twtxt.net That’s a good way to keep spammers out:

Your browser did not pass the anti-spam check! Please make sure JavaScript is enabled and try again.

It was turned on.

@david@daiwei.me Haha, great response!

@movq@www.uninformativ.de Hottest room is still at 24°C. But that will change in this week, no doubt. :-(

@david@daiwei.me I don’t want to start the discussion again, but edits wouldn’t be an issue if we had agreed on a better addressing scheme. Maybe edit more as a quiet riot. :-P

@david@daiwei.me Oh boy, that looks super yummy! :-) I want to have rain here, too!

@david@daiwei.me Exactly. Spaces are fixed, tabs always break the layout when the tab sizes are different.

@david@daiwei.me Hahaahaaahaaaahaaaaa, so good! :‘-D

Nice product, I should probably buy it:

@prologic@twtxt.net For what it’s worth, the twt hash extension is specifically modeled after yarnd’s implementation with all the quirks coming from Go’s stdlib: https://twtxt.dev/exts/twt-hash.html#timestamp-format

“All timezones representing UTC must be formatted using the designated Zulu indicator Z rather than the numeric offsets +00:00 or -00:00. If the timestamp does not explicitly include any timezone information, it must be assumed to be in UTC.”

@aelaraji@aelaraji.com @david@daiwei.me @prologic@twtxt.net It depends on the tab size, but often, a tab aligns the following character to next column that is a multiple of eight.

1      8       |16     |24     |32

@david@daiwei.me Oh no, what a giant waste of time. :-(

@arne@uplegger.eu Diese Karten sind ja echt winzig. :-)

Aber da fällt mir ein, ich sollte mir auch mal wieder ein Taschenmesser zulegen. Hab ich es doch über all die Jahre geschafft, alle schlussendlich zu verlieren.

@david@daiwei.me Ta, I continued my fun with studying the tcell and cbind code bases for key bindings. My plan is to eventually not only support custom key bindings in the tt configuration file, but also to enable multi-key sequences, such as gg to jump to the top of a list/tree. Or use other vim-like navigation movements like 7j or 25gg etc.

And it turns out there are only a hand full oft tcell/cbind version combinations that work together. Only if all stars align, there’s chance of success. I will probably end up pulling cbind in to simplify my life. There are situations where tcell.EventKey’s triple of key, modifiers and rune are not all that intuitive to me. Let’s see.

@prologic@twtxt.net Well, 15 shows the site. On the left, I had a roll mat on a tarp. I borrowed some “NVA tarps” from the scouts for this trip. The scouts got them from the National People’s Army, the German Democratic Republic’s armed forces after Germany was reunited. They’re 1.75m x 1.75m in size and weigh 1.3kg, quite heavy, but super awesome. One tarp on the bottom, another one to cover up the clothes, shoes and sleeping bag in order to protect against the thaw. Finally, a mosquito net over all that, hung from a rope between two trees.

My mate just used a hammock with a mozzie net on the right hand side. The third tarp served as the luxurious bedside carpet. :-)

We sat on my second tarp to chill and enjoy the sunset and surroundings. It was nice to notice birds etc. die down. It took a really long time for the last light to fade away. Since we have a very high risk of forest fires, we of course couldn’t have a camp fire. But after all the exhaustion, I didn’t even miss it for one second.

Since we had dinner at home before leaving, all we brought were two lye rolls, two grain rolls, two brezels, some sausage and chocolate biscuits for breakfast. From the 2.5l of water, I ended up using 2l. It’s always good to have a little extra, despite the unnecessary weight. We had brekkie a few kilometers further on a bench in the shade. The first bench was already in direct sun.

Our camp site was maybe 30m to the side and a few meters down of a summit path hidden behind some trees and bushes. We were quite lucky, the other side of the hill got quite a bit of a breeze at night. We could hear the leaved treetops making much more noise behind us.

@movq@www.uninformativ.de Yes, these kind of dogs should really be strictly forbidden!

It’s not illegal if you own the forest or ask the owner. :-)

@david@daiwei.me Yeah, no clue. But my mate said the dog is disqualified from such adventures in the future. :-)

The temps were supposed to hit 14°C just before sunrise. Since we didn’t bring a thermometer, I can’t tell for sure. I was rather hot in my sleeping bag, so I had to pull out my arms every now and then. My mate’s sleeping bag was a little lighter and, unfortunately, the zipper jammed up. Since it didn’t close all the way, it felt quite a bit cold I was told in the morning. When we got up at 6ish (we said, we don’t care about time at all), it was probably already 16°C if not more. I brought a jumper, but a t-shirt was already nice enough to wear. The jumper just served as my pillow. The mercury raised by the minute then.

Yeah, I circled the spot with a biro to keep an eye on it. Until now, there’s absolutely nothing to see. Looks like I got lucky.

We slept in the forest. It was really great except of my mate’s fucking terror dog who was barking and snarling the entire night to each and every sound. I had maybe half an hour of sleep in total. Despite that, it was pleasantly warm. Well, the night, that is. The heat was brutal during the days. Literally streams of sweat were running down on us on the way there in the evening and back in the morning.

Surprisingly, there weren’t any mozzies around at night, I would have lost all safe bets. On the way there, my mate convinced me to take a shortcut through the taller and taller growing grass. It’s been some time that somebody traveled on this track, so we had to search around a bit for the overgrown path where we could cross the mostly dried up creek. In the beginning I said that this will be a bad idea. Lo and behold, I discovered a tick on my inner upper leg the next morning. Luckily, I got it out with my tick hook on the first attempt.

@bender@twtxt.net Immediately reminded me of the German children’s song “Laurentia, liebe Laurentia mein”: https://www.youtube.com/watch?v=3Q0aky9FvLc

Have a nice weekend!

@prologic@twtxt.net I’m glad you like it. :-)

@bender@twtxt.net I bet that’s true!

@bender@twtxt.net Nice job! Without the comparison of the after photo, the grass doesn’t look all that tall before. :-D But there sure was one or the other centimeter chopped off.

@movq@www.uninformativ.de What a desaster.

@bender@twtxt.net Thanks! I wanted that to never end as well. :-)

@movq@www.uninformativ.de Even way lower than that.

@prologic@twtxt.net @bender@twtxt.net Aww, that looks so pretty!

@prologic@twtxt.net @bender@twtxt.net @movq@www.uninformativ.de @aelaraji@aelaraji.com Success!

@david@daiwei.me Some entries can be probably simplified with just *bot*. :-) (But I don’t use Caddy, so no idea about case (in)sensitivity.

That reminds me, I should do something similar with my Nginx.

@aelaraji@aelaraji.com I do use XMPP. But only the text chat part. ;-)

@movq@www.uninformativ.de Hier hab ich zum Glück überhaupt gar nichts davon mitbekommen.

Very hot above 30°C, but luckily also incredibly cloudy and a lot of wind. That’s what we got today. My mate and I went on a quick stroll this evening and got a surprise killer sunset: https://lyse.isobeef.org/abendhimmel-2026-07-07/

@bender@twtxt.net I’m glad to announce that Lyse’s Free Nose Cleaning Service is now internationally available.

@movq@www.uninformativ.de Congrats! :-)

@movq@www.uninformativ.de There is nothing like that on Linux, because you don’t need it. Everything just works!

@prologic@twtxt.net Very nice! Which boat is yours? :-)

@arne@uplegger.eu Whoah! „Schaffung eines Aufenthaltsraumes für Nichtraucher!“ Irre, dass es einen solchen vor dem 1. Mai 1975 nicht gab. Kann man sich heute überhaupt nicht vorstellen.

Cool, schönes Heftchen hast Du da gesetzt. :-) Die Lochkartenanzahlen sind auch der absolute Wahnsinn.

@itsericwoodward@itsericwoodward.com @bender@twtxt.net Oh, I missed that. Whoopsy daisy!

@kiwu@twtxt.net Hanging on by a thread is plenty good enough for many spiders, so it should be sufficient for you, too!!1!

@bender@twtxt.net I, too, should take a nap now.

@movq@www.uninformativ.de @bender@twtxt.net Indeed! No idea why this isn’t the default in the first place.

@itsericwoodward@itsericwoodward.com Twtxthashgeddon, hahahaha, brilliant. :-D

After updating to tview 0.42.0, I also sadly noticed, that the tview.Modal now clears the background and doesn’t simply draw over the already present widget. So, I decided to write my own Dialog widget. This endeavor lead me down the path to actually bring back a custom Button implementation, too. When the button is focused, it surrounds the button text with [ and ]. When not in focus, the brackets are removed. Much better than before (https://twtxt.net/conv/qx3vz4a):

I also use the same buttons in the compose view, too.

Great news, thank you! I can confirm, it looks good so far. After your change, the crawler requests every hour and five minutes: :-)

@bender@twtxt.net Thanks, mate!

On the back of the bench, the badge says: “Gestiftet Verein berg hohenstaufen Göppingen 2013”. I read that as the Mt. Hohenstaufen club donated the bench itself:

On the front of the bench, the badge says: “Gestiftet von Hildegard Schuster, Gesellschafterin der Schwarz-Gruppe, Firma Wackler”. The bronze lady was donated by a shareholder of the Schwarz group, specifically the local Wackler trucking and logistics company. Clip of 27 in original resolution:

The book itself reads: “Zur Erinnerung an Ralph Kobza” It’s in memory of the sales manager of the art foundry next town that created also this statue. My mate took this photo:

@prologic@twtxt.net That’s cool to hear!

@movq@www.uninformativ.de It sure feels like the focus is heavily shifted to the average Joe and the power users are left standing.

@movq@www.uninformativ.de Welcome to the wild west!

@movq@www.uninformativ.de I agree and am very happy about how it went for me back then. Having said that, I still admire @kat@yarn.girlonthemoon.xyz’s persistence and strong will to get into it. I feel that a lot of young folks give up way too quickly.

My mate and I hiked up the backyard mountain. We got 25°C and quite some wind, so it was actually not too terrible. The wind could have blown harder or the temps a little lower, but oh well.

I saw the squirrel’s bushy tail stick up on the forest floor in the sunlight and immediately thought of this cute little feller. Since it didn’t move at all, even when we came closer, I got irritated and reconsidered that it might actually be some kind of dried up farn. But then we also were able to see its body. Unfortunately, the squirrel ran up the tree too quickly, so all the shots are kinda crap.

At one flower spot, there were sooo many butterflies, wasps, flies, bugs and other insects. The botanic was completely crowded.

The workers were transferring logs from one log truck to the other in a parking lot. I’ve never seen this happening before. When we passed the same place on the way home, they had moved logs into a sea container. That was surprising. This semi wasn’t there on the way there. One log was probably too long and sticking out the container, so they probably had to wait for somebody to return with a chainsaw. Crazy that they’re shipping logs from here probably overseas. Why else would they put them in a sea container?

After our first break, a blackbird was really posing for us with his worm in the dark shade.

Today was my first time I ever saw a hummingbird hawk-moth (Taubenschwänzchen) for real. My mate photographed them many, many times before, but I never came across one myself. So, that was really special.

The forest service installed an outdoor table with two benches next to the timber lion, that was cool to see. We sat down for a few minutes and enjoyed both the view into the Fils valley and ant on the tabletop, but the sun was beating down too heavily on us, so we had to move on.

All in all, it was a very nice few hours long hike. Enjoy! https://lyse.isobeef.org/waldspaziergang-2026-07-03/

@movq@www.uninformativ.de https://movq.de/blog/postings/2026-07-03/0/POSTING-en.html Oh yeah, the toolbar handles. You could actually move the toolbars around and sometimes even customize them. I have no evidence, but to me it feels like a lot of programs don’t allow that anymore nowadays.
