Support graphics in rio terminal

[srid]

Requires raphamorim/rio#38

[sxyazi]

Hi, I'm interested in providing graphical support for rio terminal, but it seems that currently Yazi can only wait for rio to implement any one of the protocols like Kitty, iTerm2, or Sixel.

Alternatively, if you're using Linux, you can directly combine Yazi with Überzug++ to cover both X11 and Wayland desktop environments.

Hey @srid @sxyazi thanks for bringing it up. Would kitty image protocol be enough?

[sxyazi]

Yep, Kitty is enough.

I noticed that Rio also supports the Windows system. Due to the limitations of ConPTY, on Windows, it can only use the iTerm2 protocol. It would be even better if it could be also implemented.

I have tested iTerm2 protocol on WezTerm and Mintty, and it works properly on Windows. Of course, this is not absolutely necessary.

@sxyazi another question based on your comments,

does the sixel works on yazi for windows?

[sxyazi]

@raphamorim Nope, I can't get Sixel to work on Yazi for Windows. I've tested Mintty and WezTerm simultaneously, and none of them work.

BTW, in the case of Mintty, it's a bit special. If your program is built using Mingw GCC, just like the built-in /bin/cat in Mingw, then you can make it work only in Mintty.

See mintty/mintty#1192 for more details.

Thank you @sxyazi for the explanation, so just to confirm sixel or kitty for unix and iterm2 for windows right?

[sxyazi]

Yeah that's it. You're welcome @raphamorim

https://raphamorim.io/rio/docs/features/iterm-image-protocol/ Rio supports iTerm protocol now and I can use imgcat in it. But I can't make yazi work in it by pretending iTerm or WezTerm.

[sxyazi]

That's so weird, I can't get it to work with my imgcat, I'm using the one provided by iTerm2, https://iterm2.com/utilities/imgcat.

I did a quick check, seems it's still in progress, and part of the Rio 0.1 plan, raphamorim/rio#335

[linsui]

I tested it with https://github.com/trashhalo/imgcat (img-cat in nixpkgs). Oh, it seems this program doesn't use iTerm protocol. Sorry for the noise...

[sxyazi]

Still can't get it to work for IIP on Rio, I only see a pixelated mosaic image, which is a character-based image similar to Chafa, rather than an IIP image.

[linsui]

Yes, it seems Rio hasn't supported iTerm protocol yet thought it says

Images in Terminal
The Rio can display images within the terminal using iTerm2 and kitty image protocols.

on the homepage. I can't get the kitty protocol working, either.

[linsui]

In the latest version rio has added sixel support.

[raphamorim]

Fyi: @sxyazi I plan to add iterm2 image protocol to next version. Please let me know any issue with sixel 🙏

[sxyazi]

Image preview in the Rio terminal is now supported in #1690 🎉

Thanks @raphamorim for the PR!
