Try feh for a more configurable viewer. Note that you can run sxiv from Emacs with the 'sxiv' MELPA package, at least I think that's what it does. I guess not all Emacs users share your aversion to "external commands" ... > The function `rcd-password' fulfils the purpose of `pwgen' > to generate passwords for me. It isn't as good, that's the issue. No idea why on cannot read a non-regular file from Elisp, but head(1) and pwgen(1) can do it from C, and Emacs is written in C as well, so maybe it can be done as a C built-in (Lisp primitive) or, as said, in a C dynamic module ... -- underground experts united https://dataswamp.org/~incal
