Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

"<ESC>[31M"? ANSI Terminal security in 2023 and finding 10 CVEs
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.

Blink virtual machine now supports running GUI programs
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

If one GUI's not enough for your SPARC workstation, try four
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.

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

Hi! I made simple TUI desktop for Linux named TBox
You could probably do something like run X on Sixel for terminals that support Sixel.

Show HN: Sixel-tmux displays graphics even if your terminal has no Sixel support
> 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!

Forking Chrome to Render in a Terminal
Sixels are pixels and enjoy a wide support due to how old it is.
Kitty protocol is PNG or primitives - which BTW would make it great for a GUI library.
Different tools for different needs, but if you are going for a wide support you want something simple that doesn't have 5 different types you have to separately implement and test:
> d: Direct (the data is transmitted within the escape code itself)
> f: A simple file (regular files only, not named pipes or similar)
> t: A temporary file, the terminal emulator will delete the file after reading the pixel data. For security reasons the terminal emulator should only delete the file if it is in a known temporary directory, such as /tmp, /dev/shm, TMPDIR env var if present and any platform specific temporary directories and the file has the string tty-graphics-protocol in its full file path.
> s: A shared memory object, which on POSIX systems is a POSIX shared memory object and on Windows is a Named shared memory object. The terminal emulator must read the data from the memory object and then unlink and close it on POSIX and just close it on Windows.
> What nonsense, it takes literally 15 lines of code without using anything beyond the standard library to write a client
Conveniently taking a preencoded PNG and assuming away the necessary queries of supported protocol:
> Since a client has no a-priori knowledge of whether it shares a filesystem/shared memory with the terminal emulator, it can send an id with the control data, using the i key (which can be an arbitrary positive integer up to 4294967295, it must not be zero).

Emacs on an iPad
Not sure of Terminal emulator capabilities on Apple devices, but thanks to https://github.com/saitoha/libsixel , several applications, including emacs very much support image output in terminals.

What color do you use for your terminal?
You don't have multi-colored terminal output? Even legacy systems have long had Sixel support.

Are We Sixel Yet?
> SIXEL is one of image formats for printer and terminal imaging introduced by Digital Equipment Corp. (DEC). Its data scheme is represented as a terminal-friendly escape sequence. So if you want to view a SIXEL image file, all you have to do is "cat" it to your terminal

- Saw a few console apps and thought I might pitch in/show my own graphics library for the C# Console: The BasicRender Suite
What are some alternatives?
sixel-tmux - sixel-tmux is a fork of tmux, with just one goal: having the most reliable support of graphics
sixvid - Simple script for animated GIF viewing using sixels
libsixel - A C language SIXEL encoder/decoder implementation, forked from saitoha/libsixel after @saitoha vanished. Receives security patches, accepts PR's filed preferably here but also at saitoha/libsixel.
