Compile for batching

Compile for batching

[Kristian Nygaard Jensen]

Hi All,

I would like to know if it is possible to compile emacs for batching only.

I am aware of the options: '--without-x --without-all --without-dbus 
--without-gconf --without-gsettings'.

Is it possible to compile emacs without any user interface at all.


Kind regards

Kristian

What do you mean by "without any user interface"?  Which parts of
Emacs would you like to lose?

The editing part. I would like to be able to do emacs -Q --batch --eval, 
but I have no need for typing stuff into buffers in this use case.

(I guess the --eval argument will do some editing, because otherwise
all you'd be able doing is numerical calculations, and that will make
Emacs pretty much useless.)

No, there's no such option, if I understand you correctly.  Emacs
cannot work without at least one buffer and one window, even in batch
mode (though it never displays that window under -batch).

My primary use case is to tangle and export emacs org babel documents 
from inside docker.

So buffers are fine I just don't need to actually type anything

If you eliminate typing, you also eliminate any means of communicating
with the user.  Even in batch mode, there's sometimes the need to ask
a question and get a response.  And even SIGINT interruption goes
through the input code.

But in any case, there's no option I know of to build an Emacs that
doesn't try reading input when it's idle.

I don't know how to use docker. But I recently heard about docker-emacs[0]
project. See if using that helps. May be you can then skip creating a
docker container yourself.

On MELPA, there is the package docker-tramp. With this you can use your
local Emacs to access files in docker containers.

Best regards, Michael.

See [1] included makefile run emacs in batch mode, opens an org-mode file
then tangles source and html from it inside a docker container.
