Re: [QGIS-Developer] GSoC 2024 proposal : QGIS improve the graphical modeler UI and UX

[Valentin BUIRA via QGIS-Developer]

Hi devs,

First of all, I am really glad with how my proposal was received last
month. Now, I tried to address all the remaining issues to finalize the
proposal

I'd suggest cutting back on the scope here. There's a LOT of work here, and
a lot of complexity. I'd strongly recommend dropping the extra "quality of
life" improvements


As Nyall and others have suggested I have trimmed down the proposal to
focus on essential features. Thus I reworked the proposal accordingly, and
shifted the planning to allow more time to handle the amount of new
features and complexity.

Something to consider in your UI designs is that there's two different
"types" of expression based values for parameters

An easy fix in the UI would be to have a drop down to select either
value input or expression input and have the button to open the editor
on the right of the widget.
I went with this solution, and updated the mockup accordingly. The
nodes ended up a bit more crowded than I would like, maybe there is a
more clever way to do it..

To sum up the mapping between old and new UI:

Value -> Exposed directly on the node  with an optional  "Data Defined"
Pre-calculated Value -> Drop down to switch to an expression then
exposed on the node
Model Input -> Drag & drop input socket
Algorithm Output -> Drag & drop input socket

Concerning Custom parameter widgets, I looked in the QGIS source code, and
it looks like the Gdal algorithms use them. I will make sure to include the
Gdal algorithm in test cases during the GSoC. Now if I understand
correctly, custom parameters are not currently reflected when used in the
context of the modeler (see for example the parameter 'Additional creation
options' in gdal algorithm is simplified to the default widget for
string).  How we handle them will also help solve the issue for non-trivial
input like the the "Fields Mapper" or the "Multiple Input Layer". I checked
in other software neither FME nor Unreal Engine(with a HashMap) display
this directly in the user interface. I think we can safely let them inside
the properties windows of the node/algorithm for now.

Care would need to be taken in handling existing models. I think the new
interface would have to be opt-in


I agree with you that we need to take extra care of existing models,
however I am not that keen to have the interface as an opt-in option. I am
afraid of the additional burden to maintain two systems alongside. I'd
rather spend a bit more time polishing the backward compatibility. For
instance, while the more natural flow will be left-to-right in the new
interface, the top-to-bottom will still be possible, and we can also play
with the collapsed version of nodes, I think we could end up with a rather
similar layout for most existing models.

Do you already have a mentor planned for this work?


I don't have a mentor planned yet. I could see multiple people interested
in mentoring a project to improve QGIS as an ETL. Ultimately I trust you to
pick the most appropriate person to guide me through this proposal.

Best regards,
Valentin Buira

Welcome Aboard Valentin! Thank you for proposing this topic, which, as 
you can see from previous ones, interests us all immensely!


I hope the topic can be accepted, and we can support you.

Looking forward to meeting you and discussing it in Grenoble!

PS: Urban planner + QGIS Developer, I love it ;)

[Julien Moura (Oslandia) via QGIS-Developer]

Hi Valentin,

It's a really nice and refreshing initiative, congrats! It's really 
ambitious, hope that becomes real or at least drives the future work. As 
mentioned by Régis, the current ETL ecosystem situation is favorable to 
the emergence of an open source ETL, and QGIS Processing is clearly a 
good candidate.


Do you need someone, organization or company to support you?

See you in Grenoble to talk about urban planning and QGIS :).

Regards,
Julien

[Ismail Sunni via QGIS-Developer]

Hi Valentin,

The proposal looks great, I don't know if someone evaluates the QGIS
graphical modeler.

And as Nyall said, you can cut the scope, and the proposal is still great.

Finally we have another GSoC proposal again for QGIS :)

Good luck!

Hi Valentin!

Just to start with, this looks great and it's really exciting to see
someone take this on!

I do have a couple of suggestions for you before finalising your proposal:

- I'd suggest cutting back on the scope here. There's a LOT of work here,
and a lot of complexity. I'd strongly recommend dropping the extra "quality
of life" improvements from your proposal in order to keep your life sane!
(As a bit of a hint, take for example "A unified list for every node". I
wrote a lot of this code and I would estimate it would take me at least 2
days to do this change, and that's with decades of experience in c++, Qt
and the Qt model classes. I just don't think it's realistic that this could
be done in the same week as testing + other things). You could easily drop
the quality of life changes and still have a very compelling proposal.

- Be aware upfront that there's a lot of complexity in the model design and
widget handling. In early 3.x releases ALL of this code was done in Python,
and there were Python based interfaces for plugins to expose custom widgets
for algorithm parameters. Because of stable API restriction, we CAN'T break
those interfaces and as a result the current code is a complex interplay of
c++ underlying bits with Python glue on top to keep the old interfaces
working as originally designed. It's not pretty at all, but unfortunately
it can't be cleaned up prior to 4.0 when we can safely remove the old
interfaces. Suffice to say, there's going to be a LOT of head scratching
when reading over this code and trying to understand how it works
together. 🙀

- Something to consider in your UI designs is that there's two different
"types" of expression based values for parameters. One (which you've
already covered) is the "precalculated expression" type, where an
expression is evaluated once before running the tool and the result used as
the value for that parameter. The other is "data defined" parameter values,
where the parameter value is evaluated (or taken from a field) once for
every feature passing through the algorithm. These are distinct, different
concepts, and care will need to be taken to expose them as such in a
user-friendly way.

- Care would need to be taken in handling existing models. I think the new
interface would have to be opt-in, as the visual arrangement of models
often takes a lot of work and there's definitely users out there who have
spent considerable time in arranging their models in a logical way. If we
force everyone to use a new visual form for the designer where algorithm
blocks are different sizes and the flow appears different, it will be quite
frustrating for these users.

Do you already have a mentor planned for this work?

[Régis Haubourg via QGIS-Developer]

Hi Valentin , this is a great proposal and commitment !

The landscape of ETL is changing a lot these days with the end of Talend
open source and the costs explosion of FME.
One component we miss in our graphical modeler is the field mapping tool.
It allows to really quickly remap fields between source and destination
data sources.
This is something you could explore if you start designing new components.
See you in Grenoble !
