tmux support

[wpalace]

This program is fantastic! Thanks for creating it!

I just started experimenting with it and noticed if I remote into a tmux session which I prefer to do, images will not display. I have kitty installed on both the host and remote machines.

This works:
ssh user@somehost -t

This does not work:
ssh user@somehost -t "tmux new-session -A -s mysesh"

Hi,

Thanks for the kind words.

Only recent versions of tmux support sixel graphics (tmux>=3.4), and for this to work tmux has to be compiled with sixel support enabled. It doesn't support the kitty graphics protocol unfortunately.

It is possible to bypass tmux and send graphics commands directly to the terminal, but this is rather temperamental. You can try this by running euporie using the following command line options:

euporie-console --multiplexer-passthrough --force-graphics --graphics=kitty

(Please note that running euporie over SSH means that images may not be displayed at the correct size, as it's not always possible to detect the terminal size over SSH).

I hope that helps

Thanks for the quick response. Running the command you provided gives me a blank area where the image should be; however, if I run just the command below, I get back the graphic but it is pixelated wrong (blocky):
euporie-console --multiplexer-passthrough
Is there any way to manually set my terminal pixel size? If so, I suspect might get it working.

Can you tell if it's blocky because it's using ANSI-art style graphics, or is it using kitty graphics but just very low resolution?

Do graphics work as expected for you over SSH when you are not using tmux?

[wpalace]

Yes, the graphics work as expected on Kitty when I use SSH (either with or without -t) without tmux. I cannot tell which graphics protocol is being used when I SSH to tmux and omit the --force-graphics parameters. To investigate further, I tried another terminal. It turns out that WezTerm works as expected with SSH to tmux, and I did not need to pass any parameters to euporie-console. Sweet!

My goal is to pass lines of code from neovim, where I can quickly edit with AI assist, to euporie-console in the most efficient means possible. I tried launching euporie-console from neovim's terminal mode, but the graphics did not work from there. I tried this with various terminals, both local and remote. This appears to be a neovim issue, not euporie. The best alternative I have so far is to use two tmux windows or panes and copy-paste, but this involves a lot of keystrokes. I haven't played around with WezTerm's multiplexing features yet. Do you have any suggestions on how to achieve this most efficiently?
