Describe the bug pipe conflict between icat kitten and bash?

*To Reproduce (for kitty --config NONE)** This displays the kitty logo twice on the screen: kitty +kitten icat https://sw.kovidgoyal.net/kitty/_static/kitty.svg; kitty +kitten icat https://sw.kovidgoyal.net/kitty/_static/kitty.svg This displays the kitty logo once on the screen, followed by an error: { echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitty --debug-input +kitten icat $line; done Failed to open image: /tmp/tty-graphics-protocol-08x889_h with error: identify-im6.q16: no decode delegate for this image format `' @ error/constitute.c/ReadImage/560.

sorry { echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitty --debug-input +kitten icat $line; done should read { echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitty +kitten icat $line; done I couldn't get --debug-input to work with +kitten

One of the echos will be passed to the STDIN of the program inside your while loop. You need to use

{ echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitty +kitten icat $line < /dev/null; done

Or better yet use a real programming language rather than a bash script then you wont have these gotchas. Since you are depending on kitty already use

kitty +launch myscript.py

thanks! works. I will have to ponder why it works... much appreciated.

Thanks again for your work on kitty. As more applications support the kitty image protocol, I'm tending to run them under kitty instead of in OS windows.

The solution from Dec 6th above is still working but now writes an error message before each image:

{ echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitty +kitten icat $line < /dev/null; done

I'm still on Ubuntu 20.04, the imagemagick version is unchanged from December 2022. I'm able to reproduce the issue on the kitty nightly build as well as kitty 0.29.1

You want

{ echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; echo https://sw.kovidgoyal.net/kitty/_static/kitty.svg; } | while read line; do kitten icat --stdin=no "$line" < /dev/null; done
