  • Lightweight Emacs for container?

    From Dr. Jennifer Nussbaum@21:1/5 to All on Mon May 6 21:40:01 2024
    I usually use Emacs on full-blown Debian distributions, so I don't pay much attention to how large it is. But I'm now starting to
    play around with lightweight LXC containers, obviously headless, and would like to keep using Emacs in these, but just for basic
    text editing and so forth, I don't need a whole IDE environment. But to my surprise, even emacs-nox is a gigantic installation,
    that even wants to pull in MySQL, for heaven's sake.

    Is there some package, or a simple workaround, that will allow me to use a basic Emacs without all the cruft?

    I think the usual answers look like:

    - Use Zile (or some other small Emacs-inspired editor).
    - Use Tramp (i.e. run Emacs outside the container and access the
    container's files as a kind of remote host).

    mg and jove might be other alternatives; all of these appear to have
    minimal dependencies.

    On a fairly small Bookworm installation (standard and ssh-server tasks installed, and otherwise out-of-the-box):

    You could also try with --no-install-recommends --no-install-suggests
    to apt-get install; but there's no denying that present-day Emacs is
    fairly heavy-weight.

    Are you allowing APT to install Recommends and/or Suggests?

    If you haven't yet installed emacs-nox, it might be interesting
    to see the list of packages you get listed if you:

    $ apt-get -s --no-install-recommends install emacs-nox

    as a /user/.

    Or OTOH, if you have installed emacs-nox:

    $ apt-get -s purge <MYSQL>

    as a /user/, where <MYSQL> is the names of the mysql packages
    you're complaining about.

    The only mysql package I have (on bullseye, I'm afraid)
    is mysql-common (which is very small), and that shows:

    $ apt-get -s purge mysql-common
    NOTE: This is only a simulation!
    apt-get needs root privileges for real execution.
    Keep also in mind that locking is deactivated,
    so don't depend on the relevance to the real current situation!

    The following packages were automatically installed and are no longer required:
    gsasl-common guile-2.2-libs libgsasl7 libntlm0 mailutils-common
    Use 'apt autoremove' to remove them.
    The following packages will be REMOVED:
    libmailutils7* libmariadb3* libreoffice-sdbc-mysql* mailutils* mariadb-common* mysql-common*

    Purg mailutils [1:3.10-3+b1]
    Purg libmailutils7 [1:3.10-3+b1]
    Purg libreoffice-sdbc-mysql [1:7.0.4-4+deb11u8]
    Purg libmariadb3 [1:10.5.23-0+deb11u1]
    Purg mariadb-common [1:10.5.23-0+deb11u1]
    Purg mysql-common [5.8+1.0.7]

    (I have emacs-gtk installed, rather than -nox.)

    Cheers,
    David.

    Tramp is the way to go, for a bunch of other reasons. You carry around
    your set of customizations. You have less instances to keep up to date
    and to care-and-feed.
