see discussion on Mauro's thread about
the fact that it is probably just easier to use Emacs directly
if you
need to export
to a certain format in a specific way. It is free software
after all.
I would like to add, that this is pretty easy to do, and also to
make
independent of the users emacs environment. Here is an example
that
uses the whole orgmode-babel-latex-html machinery to create
derived
documents from source-of-truth org-mode files which get exported
to a
book:
https://hg.sr.ht/~arnebab/ews/browse/Hauptdokument/ews30/Makefile.am?rev=b8e3899c6d8b#L121
chargen.tex: chargen.org $(ewstables_SOURCES)
kasten-alter-groesse-gewicht.org ews30setup.el
echo yes > $$(tty); Xvfb :3 -screen 0 1024x768x16 & time
DISPLAY=:3 HOME=@abs_top_srcdir@ @EMACS@ -l
"@abs_top_srcdir@/ews30setup.el" --eval '(setq
vc-follow-symlinks nil)' --eval '(setq org-id-locations-file
"@abs_top_builddir@/.org-id-locations")' "$<" -e
org-latex-export-to-latex -e kill-emacs < $$(tty) >> build.log
&& rm -f "@abs_top_builddir@/.org-id-locations"
Note how this sets the HOME to the sourcedir (so a
project-specific
.emacs.d setup is used) and loads ews30setup.el at startup for
additional customization. Also note the call to Xvfb which
avoids
showing a graphical Emacs during build.
This uses an org-mode file that pulls data from tables in other
org-mode
files by setting variables for code based on autotools-included
datafiles. Here’s an example of pulling the tables into
variables:
https://hg.sr.ht/~arnebab/ews/browse/Hauptdokument/ews30/chargen.org.in?rev=b8e3899c6d8b#L153

Note the {{{…}}} blocks. Those use literate programming to
include
blocks defined below, with customized separators:

# org-export-allow-bind-keywords: t

Here’s how it pulls tables:
https://hg.sr.ht/~arnebab/ews/browse/Hauptdokument/ews30/chargen.org.in?rev=b8e3899c6d8b#L578
@tabelle_aussehen@
And this is an example of the datafiles that are used as
source-of-truth
and also directly inluded in the main book as tables:
https://hg.sr.ht/~arnebab/ews/browse/Hauptdokument/ews30/tabelle-aussehen.org?rev=b8e3899c6d8b#L578
#+tblname: tabelle-hautfarbe
| | -5 | direkt | 6 |
|------+--------+-------------+----------------|
| -3 | blass | rosig | sommersprossig |
| -1 | grau | gelblich | elfenbein |
| 2 | kupfer | rotbraun | bronze |
| 4 | oliv | dunkelbraun | schwarz |
| -5/6 | albino | - | fleckig |
All this machinery can be invoked without ever seeing Emacs.
So yes, the Emacs implementation is the source of truth, and
yes, this
can be used without requiring people to operate Emacs by simply
using
Emacs as utility with project-specific setup — just as you would
do it
with a compiler.
Best wishes,
Arne
