Using wezterm imgcat $file in a loop -- each vs for

[g-gundam]

Suppose, I have a directory of JPEG files, and I want to use wezterm imgcat to display them inside a wezterm terminal. I could run the following for-loop in nushell to do that.

for file in (ls *.jpg | get name) { print $file; wezterm imgcat --width 10% $file }

However, when I tried to do something similar with each, it didn't quite work.

ls *.jpg | get name | each { |file| print $file; wezterm imgcat --width 10% $file } | ignore

The print works, but wezterm imgcat does nothing visible in this case.

Can someone explain to me why this is happening?

Can someone explain to me why this is happening?

The output of all runs of wezterm imgcat was collected into a list (this is what each does), and then that list was passed to ignore, which discarded it.

it would have worked if you used to text (which concatenates lists) instead of ignore

Thanks for the clarification. Using to text made it work like you said it would.
