So why was it removed? I cp'ed it from /usr/bin/xv of an earlier
(pre-Oct18,2019) 64-current, and it continues to work fine and be very
useful (for me at least).
I'm only guessing, but my guess is that it no longer compiles from
source. The fact that an old binary still runs does not mean that its
source would compile with a new compiler and new glibc with latest header
Version 3.10a of xv is from 1994.
you will find beside the source package a number of patches from others
than the original maintainer. Some of those patches add functionality
like support for .png files. However, I am sure that some patches are
there to make it compile in an environment newer than a 1994 Unix system.
Unmaintained source code suffers from bit rot stops working.
Like you I will miss xv, I use it every week. It is the most convenient
toll to have a quick glance at an image and it is also a very convenient
tool to make and save screenshots.
It might also be worth noting that even though the source is available
for xv it has a shareware-like license which is free for personal use
only. Commercial users of xv must pay to the original author.
