Re: [darktable-user] Best way to tag image from command line?

[Terry Pinfold]

I have never paid any attention to the collect images module before. I am 
impressed with how you can search for images based on criteria including aspect 
ratio, camera, focal length, ISO and the list goes on. Very impressive and 
comparable to the search feature found in Lightroom (but without the cost of a 
subscription:)

You're right, there's no way to filter based on the camera's rotation
sensor. But we do have something better, that takes cropping into
account, too.
In collect images, open the dropdown, and select aspect ratio:

Choose one that you like, or use > 1 to filter for landscape:

Since they both say 3.4, and in fact *are* for 3.4, the question was
valid and the answer was just as wrong as arrogant.
https://darktable.gitlab.io/doc/en/index.html is 'old' in the sense
that it's the updated version of the 'old style' manual. Nevertheless,
it has been updated for 3.4, but is the last such update. It is
available in multiple languages.
https://www.darktable.org/usermanual/en/ is the new version, and that
is the format that will be used in the future. It has fewer
screenshots (which tend to change often, and are therefore hard to
maintain).
Finally, https://darktable-org.github.io/dtdocs/ is, as far as I know,
the latest and greatest, updated for the development version (even
though its version number still says 3.4). It's automatically
generated from https://github.com/darktable-org/dtdocs
The latter two are currently available only in English.

Re: [darktable-user] Windows Nightly Builds

No, you’re looking at the right place. There seems to be some issues in setting 
up the ci environment for windows.
Best way is to build it yourself - the description in 
https://github.com/darktable-org/darktable/tree/master/packaging/windows is 
quite good (but a setup in a ci environment is a different thing)

Both of those links are for 3.4

I believe this is the better link going forward as it will be maintained
with updates (that what I read previously on this forum).
https://darktable.gitlab.io/doc/en/index.html

The other is a PDF version and I believe it lags behind on updates.

You already got an answer. This is available and is called aspect

Thanks,


Pascal,

You are one of the developer of the darktable and I respect you for the 
work you have done. Since i am not a contributing member right now, all 
I can do is propose the ideas. I have read manual many times and when 
not clear I have asked the questions and got excellent support from 
community. I was just looking for a way extending already excellent tool 
and discussing the ideas.


If you don't think feature is not worthy of implementation, we can drop 
the topic, no worries, but language like "certainly never happen" feels 
like not considering other ideas without full consideration or reasoning 
behind it.



After I refresh my C/C++ skills, skills used long time back, I might 
create a pull request with my ideas for your consideration, my idea of 
what can be done. You don't have to accept the pull request, but it will 
give me some satisfaction of taking some action and not just talking.


Thank you for the hard work and a excellent product.


Regards,

Niranjan

I wouldn't want to comment on other's experience. Here is what I was 
looking for and so far I have not found a way to do in darktable. Any 
tips/hints welcome.


I was looking for portrait images. I could not find a way to do it in 
UI. Darktable is aware of image orientation, but it's not accessible in 
UI as far as I know. Besides it uses different values than standard exif 
values, but comments in the code make it clear why it was done that way 
and makes sense.


If I had access to query editor, I could have easily have a query and 
don't have to wait for a feature that may or may not be implemented.


I'm trying to understand resistance to SQL query - as I see it,  it's a 
view after all, it has list of images and should not care how it got the 
list of images. As far as i can see current view is basically result of 
SQL, either based on film role or tags or whatever. If you provide 
opportunity people will use it in imaginative way, after all this tool 
is used by many imaginative artists. Why constrain within the confounds 
of UI?


I agree that SQL is not for everyone, but that does not mean other 
developers can provide SQL that can do allow people to filter the way 
they want or enhance functionality of already excellent tool. Not 
everyone is able to contribute with C/C++ tools, but following linux 
philosophy, any tool should be easily extendible by others without 
significant changes in the original tool.


Thanks,

Niranjan

Re: [darktable-user] Best way to tag image from command line?

[DougC]

The idea of providing a way for users to submit SQL queries to filter the image 
list in lighttable is an interesting one. Not for everyone, certainly, but 
useful for some.



It is similar, in some aspects, to the ability to add CSS in the configuration 
dialog to customize the GUI. (Normally, CSS is used internally to manage much 
of the GUI look, but the user gets the ability to add their own tweaks.)

Re: [darktable-user] Best way to tag image from command line?

[Niranjan Rao]

I respectfully disagree with SQL injection aspect. I'm aware of SQL 
injection and damages it can cause. Problem can be addressed in multiple 
ways.


 * darktable is single user database - that is data belongs to only one
   user. There is no data leak across multiple users of the application.
 * Damaging database such as dropping/deleting rows/tables is certainly
   possible, but it can be managed by read-only transactions or similar
   techniques.

I agree that SQL is not everyone's cup of tea or other preferred 
beverage. That's why I said others can help forming the SQL. Essentially 
goal is to come up with a result set of images that can be shown in 
lighttable view. One way is to write the SQL that returns a list of 
images based on given criteria. lighttable is essentially doing it after 
removing the GUI sugar. If a custom SQL can return image list, lot of 
problems can be easily solved - e.g. FAQ can maintain a list of approved 
SQL queries that can show the results.

Perhaps look up "SQL injection"?

Apart from that, SQL isn't all that simple to use, a few of the concepts are
not self-evident.

script ???

you must start dt from the command line using the command I provided but
changed to fit the way you named the config directories.  the following
command line invocations will accomplish that,

darktable --configdir ~/.config/darktable-3.4
darktable --configdir ~/.config/darktable-master

and library.db and data.db will be in the *correct* directories.


there is no script involved and any script that you used probably did not
have any idea of where you placed your new config directories.  it was
probably coded to default to the normail installation location, ie:
~/.config/darktable

again, to start and use darktable master version, invoke darktable from
the command line as:
  darktable --configdir ~/.config/darktable-master

to use darktable version 3.4:
  darktable --configdir ~/.config/darktable-3.4
  
note:  using "-" in directory or file names is ill advised and asking for
problems.


about "alias", your ~/.bashrc must provided for it and more, another
subject for another time.  please for now, forget it.

the commands above may be placed in scrpts to make it easier to call.  I
can help with that if you wish.

Patrick,
Thanks for the info, although I don't know how to create an alias. Do those
commands go inside the bash script?
Also, I followed your advice to create folders inside .config (except I
called them darktable-3.4 and darktable-master) and then point the bash
scripts to those folders.
But when I launch darktable 3.4 from the bash script, it creates new
library.db, data.db etc in .config/darktable (not the folder
.config/darktable-3.4)

move ~/.config/darktable
to   ~/.config/darktable.34
and copy to
 ~/.config/darktable.35

then call darktable version 3.4 as
 darktable --configdir ~/.config/darktable.34
and version 3.5 as
 darktable --configdir ~/.config/darktable.35

and I would create aliases rather than the long command lines.

alias dt34='darktable --configdir ~/.config/darktable.34'
alias dt35='darktable --configdir ~/.config/darktable.35'

should accomplish what you desire

note that you will start with matching configurations, only differences
will show after you start using
