xserver-SIXEL VS XQuartz

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!

I couldn't get dillo to compile easily on macos, it doesn't seem to detect ssl libraries installed on the system)

you can do this to compile it on macos (tested on M1):

install https://www.xquartz.org/ to have X11

brew install fltk libjpeg #you might also need openssl@3 but unsure

git clone https://github.com/crossbowerbt/dillo-plus/; cd dillo-plus

# update the 1.3.8_1 fltk version

brew install --cask xquartz

Or install from the project homepage [1]. Then just launch the X11 app. Note that it does require the application to be built for Mac - it’s not an emulator, just an implementation of the X11 APIs.

I’ve recently spent some time working with terminal emulators in raw mode on macOS. While I chose to handle key events using escape codes, and found it seriously difficult (even gave up) to process the shift modifier key. However, I came across xquartz [1], which seems to do similar things as mentioned in the article. Would detecting shift key state have been trivial using such a library?

The contents are rendered through gtk/cairo which not only goes through https://www.xquartz.org/ but also doesn't use GPU rendering (it was experimental 3 years ago, maybe better now). The main issue seems to be that neither Inkscape nor gtk people have much low level Darwin experts or time available to invest in debugging the whole rendering stack. See for example https://gitlab.com/inkscape/inkscape/-/issues/1614 and all the other referenced issues for all the gory details.

I live in a mezzanine studio using a M1 macbook for a workstation (writing/editing) and my old laptop with openbsd as a local server. I play music from that obsd server upstairs, which thus fills the whole room down to my desktop through the plugged-in speakers. My hosted library plays fine with mpd and ncmpcpp, and I just figured out it's not so difficult to use mpv to play streamed youtube videos, since firefox in XQuartz streaming from xenocara is way too slow anyhow.

There is an alternative: I ended up using Xquartz to give me an X11 environment and then running StumpWM as my tiling window manager. I used this for all my productive stuff, running full screen in MacOS, then a quick keypress got me back to the Mac environment.

I also used Xquartz. Emacs was better for me though because capturing text output and documenting what I captured was so much easier than X-window.
