When running 'crontab -e' with $EDITOR set to
emacsclient -nw -c --alternate-editor=""
emacsclient issues an error that it had failed to locate the emacs
daemon socket file, so it spawns a new emacs daemon. On this
distribution (Devuan Ascii/Ceres, a derviative of Debian 9 without
systemd), the socket file is located at:
/tmp/user/${UID}/emacs${UID}/server
which in this case the emacsclient binary isn't finding or looking for.
However, in other uses of emacsclient via $EDITOR (eg. mutt, newbeuter,
w3m) the client does find the socket file and does connect to the
existing daemon.
A work-around has been to define:
export EDITOR="$HOME/.local/bin/emacsclient_wrapper"
alias emacs="emacsclient_wrapper "
#!/bin/sh
# emacsclient_wrapper
SOCKET_FILE="$(lsof -c emacs -u $USER | grep -m1 -o "[^[:blank:]]\+server")"
[ -z "$SOCKET_FILE" ] \
&& emacsclient -nw -c --alternate-editor="" $@ \
|| emacsclient -nw -c --alternate-editor="" -s "$SOCKET_FILE" $@
