Thank you. I'll try it out.
I did manage to find few interesting tags from exif information - just
by comparing tag information between three images shot by camera for hdr
vs single image. It looks promising for one of my camera. Did not get
enough time yet to investigate if same concept can be applied to other
camera.
Now debating over Java vs (bash) shell script to get exif info and
collect the potential images I'm interested in.

To use the lua scripts do the following
Open a terminal then:
cd .config/darktable
git clone https://github.com/darktable-org/lua-scripts lua
ln -s lua/tools/script_manager.lua luarc
start darktable
a module will be present at the lower left called script manager.
Open it, select the scripts you want to run and enable them, and enjoy

Greetings,
On darktable version 2.6.2, Ubuntu 18.04.
I know how to generate HDR images in darktable, basically select
images
from lighttable and under selected images menu, click on create HDR.
This works.
However it's getting tedious for doing many images and getting error
prone. So, I'm exploring batch options. Anyone has any ideas? I'm
comfortable writing shell scripts or Java code if needed. I have not
explored darkable/Lua combination yet.
For batch mode I see I have to do following
Figure out images which can be grouped together for HDR. I don't
know if
cameras write any special tag in raw file that might help. If not,
only
option seems to be check tags like time stamp, focal length and such
that will remain same. For my purposes, these fields most likely
will do
the job and get me the names of the file unless I find a better
way to
identify the images.
Once I have managed to find the group, next task is convince
darktable/lua to create HDR from the selected images. This is
where I am
stuck. Quick search revealed
https://github.com/darktable-org/lua-scripts which has few promising
leads e.g. enfuse. I'm not clear how to use it.
Looking for any pointers/help.
Thanks in advance,
Niranjan
