sixel-tmux VS xserver-SIXEL

It's not really that strange that tmux doesn't support sixels. It's quite a bit more complicated and resource-intensive than ANSI Escape Codes or ncurses.

It might be fine for local[1] multiplexing but over the network it is not as fast as even something like VNC or RDP.

After having spent too much time trying to get the simple https://github.com/csdvrx/sixel-tmux/ features into mainline tmux (last November https://github.com/tmux/tmux/issues/3753), maybe it'd be easier to jump ship as use zellij?

Could anyone offer recommendations on "riced" zellij configuations, or just a demo where it shows doing with (say charts of disk usage per folder), watching a movie with mpv + keeping a vim to type on?

Your approach looks very sound!

A fork of terminfo may be needed if the description of modern terminal capabilities can't be added -- or if old and deprecated attributes repurposed for that job (like in your padding example): if you're automating the correction/creation of terminfos in ~/, IMHO, it may be better to piggyback on tic as much as possible.

Anyway, to backport modern terminal descriptions to legacy programs, creating correct binary terminfos in ~/.terminfo seems the best practice. You can also invent new TERM. When I wanted to have italics etc about everywhere, personally that's just what I did for sixel-tmux: https://github.com/csdvrx/sixel-tmux/?tab=readme-ov-file#ste... : just declare a new $TERM you know to be right, and use that in the apps that let you use a little logic in their configuration file

I do that in my .vimrc:

   " If Vim doesn't know the escape codes to switch to italic

You can have that functionality integrated within tmux with https://github.com/csdvrx/sixel-tmux/ : if you terminal doesn't support sixels, you'll at least see something close to the picture they represent.

Then of course it's not pixel-perfect unless you make your terminal very large (like 800x240 instead of 80x24) but something being better than nothing, I'd argue it's for the better if all you can do is 80x24 with no pictures otherwise.

sixel-tmux can help you have both: https://github.com/csdvrx/sixel-tmux/

> It's 2021, and we should be able to do litterate programming in the console, with full graphical support.

Yeah. We are stuck cosplaying computers from the sixties.

What's even funnier, even if you find a modern terminal emulator that supports features like ligatures, graphics, emoji etc. you still will be blocked by tmux. Sure - not everyone needs tmux. If you never work on remote machines, you can live without it.

But I work on remote machines all the time. I also use Kakoune text editor that defers window management to external tools (WM or tmux, but to be honest, tmux is much better). Zellij is more of r/unixporn bait than usable tool for now. So I'm stuck with text only interface.

> Some terminal emulators have support for images, which fit most of the use cases here but not the one I described.

That what sixel-tmux is for, when you're in a hurry and needs images with your current terminal emulator: https://github.com/csdvrx/sixel-tmux

Maybe tmux-sixel does that tmux sixel

If you want some crazy shit like sixels or italics and ligatures, try msys2 that's what I've used for the screenshot. The only thing comparable on Linux in term of features is xterm and, that's another story.

If you really want crazy, run `xterm -ti 340`, then run run an X server from the xserver-sixel repository <https://github.com/saitoha/xserver-SIXEL> in it. Now y ou can run as many terminal emulators, complete with real truetype fonts and all the colors you could want, inside the one terminal. Use a tiling window manager and you’ll be able to avoid using tmux entirely.

There's a X with sixel support: https://github.com/saitoha/xserver-sixel

I played with this before, and I could use X11 within a mlterm terminal.

I should try to recompile it with cosmopolitan to have a single X server binary both for Windows and Linux

What you do is run `xterm -ti vt340`. If your xterm was compiled with SIXEL support, this will enable it. (You can test it by running something simple like `gnuplot -e "set terminal sixelgd; set key bmargin center horizontal; plot [-5pi:5pi] [-5:5] real(tan(x)/atan(x)), 1/x"`.)

Now run Xsixel (from <https://github.com/saitoha/xserver-sixel>) to run an X server that outputs to sixel graphics. In that X server you can run any program you would like, and its graphical output will be converted to sixels, printed to stdout, given to xterm, and then xterm will draw them.

Job done!

See <https://saitoha.github.io/libsixel/> for more information and tools, along with lots of screenshots.

There's a version of X for these terminals: https://github.com/saitoha/xserver-sixel

You could probably do something like run X on Sixel for terminals that support Sixel.

> unfortunately it's way too slow to get anywhere near 'realtime' output (30fps or better).

That's not due to sixels. Check out the sixel nyan cat: https://github.com/hackerb9/sixvid

Look at the FPS indicator in the bottom. It was pointed to me in https://github.com/microsoft/Terminal/issues/448#issuecommen...

The issue may be in your code.

I think I have similar performance issues, as the glyph selection process could be more optimized.

Derasterized is mostly Jart work (who is best known here for her work on Cosmopolitan), we were mostly interested in quality.

Reducing the set of glyph to something that could benefit from optimizations could help.

> I really wish there was a decent pixel-framebuffer standard for terminals (with at least the same performance as ncurses)

Sixel performance is quite decent: personally, I can play videos in my terminal.

Try MPV on mintty: https://github.com/mpv-player/mpv/issues/2183

I have also played with a X server rendering over sixel, no performance issue: https://github.com/saitoha/xserver-SIXEL

When sixel support is added to Windows Terminal, I may update it, because it would be fun to have one tab to run stuff!
