Provide a Command to Modify the File List Through a Script

[baskerville]

I thought it would be important to be able to sort images on the fly.

I'm proposing the following approach:

Provide a command that would provide a script the current list of images being handled as a list of newline separated absolute paths to the its stdin and read back the modified list on the its stdout.

For example, the following script would eliminate non-existent files:

#! /bin/dash

xargs ls -1d 2> /dev/null

And this script would sort files by size:

#! /bin/dash

xargs ls -1dS

I don't consider this important.

Why?

I don't have enough time. And I don't consider sorting images on the fly an important feature, which should be included in a suckless image viewer. If you want images to be sorted by file size, then you can start another instance of sxiv with the appropriate order of its file arguments.
