The solution I use on my Linux computer is to compile GNU emacs (fetched with
git clone) from its source code daily.
It takes a few minutes, the time to drink your morning coffee.
Here is the script (in $HOME/bin/getemacstrunk) I use to fetch and compile it:
#! /bin/bash -x
export PATH=/usr/bin:/bin
sync
cd /usr/src/Editor/emacs
rm -f etc/DOC*
git pull
git log -3 | cat
sync
oldemacspids=$(pgrep -u $(id -u) emacs-trunk)
if [ -n "$oldemacspids" ] ; then
kill -TERM $oldemacspids
printf "%s: killed %s\n" $0 $oldemacspids
fi
rm -rf /tmp/emacsinst/
time nice make -j 6 -l 9 || exit 1
sudo /bin/mv -v /usr/local/bin/emacs-trunk /usr/local/bin/emacs-trunk~
time make install DESTDIR=/tmp/emacsinst || exit 1
sudo /bin/cp -v -r -p /tmp/emacsinst/usr/local/. /usr/local/.
sync&
