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.

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).

contains img2sixel, which lets you dump images to the terminal. It can also do animated GIFs.

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

Contour: Modern and Fast Terminal Emulator
- you can also rectangular select like in vim, and then press either p (includes LF) or which joins the multiline clipboard text into a single line (removing LF's), that payed off a lot for output like `git status` and wanting to operate on parts of the output (files e.g.)
Have a look at the still young website's documentation here: https://contour-terminal.org/input-modes/#supported-text-obj...
for a more complete look of what you can do with the keyboard (normal mode) :)

GNOME’s horrid coding practices
Also, regarding VTE, the author of termite (discontinued terminal emulator) expressed similar concerns about the GNOME devs. Apparently, they have little interest in making the library useful to people not working on GNOME apps: https://github.com/thestinger/termite

Why are kitty and alacritty so popular? Where's the foot love?
I simply do not want to use anything libvte based. And that's what sakura is and termite used to be.

Show HN: Sixel-tmux displays graphics even if your terminal has no Sixel support
> https://github.com/thestinger/termite/blob/master/README.rst...
Wow, this confirms a lot of my impressions:
>> In 2012, we submitted a tiny patch exposing the APIs needed for the keyboard text selection, hints mode and other features. Despite support from multiple other projects, the patch was rejected. It's now almost a decade later and no progress has been made. There is no implementation of these kinds of features in VTE and it's unlikely they'll be provided either internally or as flexible APIs. This is the tip of the iceberg when it comes to their hostility towards other projects using VTE as a library. GTK and most of the GNOME project are much of the same. Avoid them and don't make the mistake of thinking their libraries are meant for others to use.
This is exactly why sixel-tmux exists as a separate entity!
> Yeah, I read the entire conversation and if sixel support lands in tmux upstream, it would indeed be good news.
I'll keep my fingers crossed, but right now, there seems to be a lot of good will. I will do everything I can.
