I'm not gonna lie, #uxn is the cutest damned thing I've seen in a while.
Someone made a custom portable virtual machine called the #Varvara and wrote code for that machine while following vintage design patterns.
It can run on any platform, including the browser and is a machine agnostic system. You can make applications, desktops - and it isn't limited by traditional hardware constraints.
"Let's try to go slow, and fix things."
Priceless.

@neauoire may I propose: varvara touch input, as an extension of the mouse device
additions:
- one byte for touch id (0 means no touch i.e. mouse input)
- one byte for touch pressure (>0 is down, 0 is up)
xy coordinates will reuse that of mouse device
as for pointer emulation, the varvara impl can fill in state/scrollx/scrolly as appropriate (e.g. one finger means leftclick, two finger means rightclick)
so if I use noodle with a touchscreen, it'll treat my touch input as the mouse
but if I use a rom that supports touch, it can detect touchid>0 and handle my touch input accordingly!
wdyt ^^

Ihre Leseleidenschaft hat Varvara schon viel beim Deutschlernen geholfen. Deshalb hat sie bei Little World den „Buchclub“ gegründet, wo sie sich mit anderen über Prosa und Poesie austauscht. -

I made a #gapbuffer in #uxntal in about 500 bytes of #uxn bytecode!
https://paste.sr.ht/~ismael-vc/4e90f62e9149f8b7a0dc91175abcb4a367e8f35b
It outputs:
https://paste.sr.ht/~ismael-vc/bc25e5df6cbe5f3d01fc4c8d8f4477253d67b2b2
(Gap size 4 bytes for debuging purposes, I still need to do proper bounds checking but I think that's about it.)
Used this as reference:

I finally got some time to work in kibi today, I have impremented and debugged kibi/get-win-size, kibi/get-cur-pos (used to get the window size) and updated kibi/draw-rows to draw the correct number of purple tildes on the first column. 😊
I also made the makefile a lot nicer. 🧘♂️
That means I'm almost at the middle of chapter 3 "Raw input and output", at step 35 of the original tutorial (special case the last row)! 🚀

Do you think this formated #uxntal table using ASCII control codes and markdown inspired macros to delimit data is readable?

@rl_dane @mdc I wonder how #uxn opcodes compare to what F18 chips from #GreenArrays have.
Only 32 opcodes, 8 of them special (can be used in th last 3 bits of a kind of 18-bit #VLIW word) versus 256 opcodes of #uxn
#varvara offers much more high level i/o, F18A has 4 interchip ports, GPIO, A/D interface and SERDES, which can be used to build things like Ethernet for example.
varvara-fpga does not implement most varvara I/O features at all.https://www.greenarraychips.com/home/documents/greg/DB001-221113-F18A.pdf

Good evening, and welcome to Uxn News Today!
In our top story, Angelwood has just announced an exciting new project on Discord: an uxntal #barcode generator!
This innovative tool, designed for the Uxn ecosystem, is now available for exploration.
You can check it out at https://git.sr.ht/~angelwood/upca-uxn. Stay tuned for more updates on this development, and join the conversation with hashtags #uxn, #uxntal and #varvara.
That’s all for now—back to you!

I am very aware of the #uxn and #Varvara stack machines, and have looked closely at them. Lots of software applications. The reason I did not take that path, is that they are optimised for 8/16 bit CPUs. The #J1 / #MecrispIce family is much better optimised for FPGAs.

@tsalvo Just saw your work in progress on the stack #CPU implementation in #PipelineC 👋 . Great work, how neat! Hope it has gone well and as always happy to help! 🤓 #uxn #varvara #AnaloguePocket #FPGA #stackmachine #FPGA #HDL https://github.com/tsalvo/varvara-fpga
