I'm starting to wonder if maybe I shouldn't start adding forth
syntax-highlight to Left now that you're nearing having Varvara up and
running. Is there anything at all you'd like me to prepare in advance?
My guess is that you're aiming for screen.tal, mandelbrot.tal, picture
drawing examples that make use of the filesystem, polycat.tal and
controller.tal for input, and by that point Left should be usable -
And Dusk modifiable from within itself.

So, if there's anything that you think you'll need to make this
easier, let me know and I'll get right to it.

Hey everyone,

From time to time, someone asks if there's something like Uxn32's
debugger planned for the other emulators, and since we can't quite all
agree on the API needed to make this happened, I went ahead and wrote
a uxn emulator, in uxn itself.

source: https://git.sr.ht/~rabbits/beetbug/tree/main/item/src/emulator.tal

This allows anyone to step through their program and follow the stack
states and follow the PC around, it's totally portable, it doesn't
make use of any special System port. I'm sure there's still some
improvements to be made for it, but I've used it today to step through
a bunch of routines I was implementing and it delivered.

Hi everyone,

I'd like to follow up on that thread with a link to the documentation
for the metadata standard, for anyone stumbling on this link in the
future:

https://wiki.xxiivv.com/site/metadata.html

I've also made a little graphical utility to test metadata

https://git.sr.ht/~rabbits/uxn/tree/main/item/projects/utils/metadata.tal

If you want to add metadata, but don't have the space or need to store
a whole 64x64 icon, use =ffff as address for the app icon.

Hello everyone,

Long time no talk, I had a question and I'd like your opinion.
binarycat needed raw byte values for their project, and I did a quick
scan of some of my own projects and found a good couple of .zplabel
STH, which should really be more like LITr -zplabel

So I was thinking, what would you say if on top of : for raw label
shorts, I added =label for raw shorts, and -label for raw bytes?
Consider your macros that might begin with - or =.

Let me know what you think :)

Dll

Thanks :)

Hi all!

I've been working on this Uxntal operating system for the better part
of the past few days, and I started noticing that things were kind of
weird, and that building without tail-call optimisations resolved the
issue, the project is massive and I couldn't for the life of me,
figure out where the optimisation issue was occurring.

https://git.sr.ht/~rabbits/potato/commit/8323c42390821050418503bfd823aba17dd821b4

So yeah, be careful out there, I'll try to weed out the bug and figure
out which part fails. Just a head's up :)

Have a good rest of summer

This is specifically for Felix, but I'd like to make this conversation
available to all, in case anyone has ideas.

In UF, when uxncli under/overflows, it breaks the repl. It'd be nice
to agree on a way to handle this stuff by using this as a usecase.

The way I would handle this is to set a System/vector and clean up the
stack in that vector, and throw a custom error. Do you think that
would work for you? We could make that behaviour standard across
emulators if that would do it? What would be the ideal UX to handle
that?

I've implemented a simple check using a device support bitmask at the
emulator level, it'll catch 90% of the incompatibility issues which
will likely be folks trying to run graphical roms with uxncli.

The report came from someone using uxn11 on BSD, but this should
probably be added to uxnsdl as well.

https://git.sr.ht/~rabbits/uxn11/commit/5d837313e56d19cd6ecfa2ad9746edca20afb5f6

Found an exception.

The file device is a bit tricky I suppose, for example, noodle doesn't
assign a File/name until it tries to save, but the device does have a
vector, although it is unused.

Maybe applications should still test available devices on reset, I
could set a #0000 to File/vector on reset to make sure that it is
available.

If all else fails, a bit mask in a byte might work, but let's try to
see if we can do without first.
