This PR is based on #684
As I understand the handling of
send.json
in thesend
function, it prints but ignores an error ofutils.GetConfigDir()
. I tried to copy this behavior to thereceive
function:If
utils.GetConfigDir()
fails, the error is printed and returned toreceive
. Though, croc only exits ifc.Bool("remember")
istrue
, because only then, the config file is really needed.This may be related to #681
