The implementation in D101 has caused problems with being able to run the python example GenFit3pi.py because to be able to use our classes in python they need to have dictionaries generated.
As such, I'm going to revert the changes from landing D101 and make new commits that only apply the following parts of those changes:

• Removal of the deprecated ClassImp macro in all source files
• The improvements to the CMake modules to avoid using old-style CMake stuff like file-level include_directories, etc.

The updated formatting looks good. This is ready to be merged for the new release.

Hi @jback, just a quick note to explain the new changes.

• Updates to clang-format style for clang 16
• Modify clang-format style to 4-space indentation
• Fix missing newline in README
• Scripts to fix indentation of Doxygen comment blocks
• Further improve formatting style
• Re-apply formatting to source files

Formatting and CI check look OK.

Yes, this is OK.

• Apply formatting in v3-patches branch

@jback, does this look ok? It's the same as the code we now have in #evtgen.

• Add warning if requested C++ standard is too old

Thanks John!

Clang formatting and CI check looks OK, so proceed with organising the appropriate branches.

It looks like it is going to be a nightmare to merge timedep-branch into master if we apply this formatting first (even after applying the same formatting there first).
So what I'd propose is to merge the last actual code changes into master - will create the differential for that shortly - then create a new v3-patches branch, to which this formatting can then be applied, and release v3r6 from that branch. This Differential can be updated to accomplish that part.
The formatting can then be applied to master after merging in timedep-branch - will require a separate Differential at a later date.
Does that sound reasonable?

Thanks to D101, this is now in master but needs to also be propagated to the time-dependent branch, so not yet closing this.

(not sure why this didn't happen automatically)

In parallel I need to check what happens if I apply the same formatting in the timedep branch and then try and merge the branches! If that doesn’t go so well we might have to postpone this change untill after merging timedep into master.

Since this is purely formatting changes, I think the main thing to review is that the formatting style looks reasonable and that the CI check looks ok. Up to you if you want to look through all the files!!

Remove unused member variable from LauKMatrixPropagator

Many thanks for checking through this. I’ve reply to your K-matrix related question inline.

All of the changes look OK. Just have a query about some K-matrix code that is commented out. Otherwise this can be merged.

@jback - just to provide you with a bit more context. This is the first of three Differentials that I would like to get merged before releasing v3r6 from the master branch:

• This one, which addresses T213, solving an issue with and generally improving the ROOT dictionary generation
• One that will address T111 by creating a clang-format style file, applying it to the code, and adding a corresponding CI check
• One that will address T227 by creating new functions in the fit models to access the amplitude and likelihood as a function of the DP position

Fix typo in release notes

• Further tweaks and added release notes, example usage removed from GenFitDpipi

Please also add an entry in the release notes, which should reference either this Differential revision or the corresponding Maniphest task

Just a few trivial tidy-ups

• Missed one issue

• Address review comments

Many thanks Mark, this looks great. Just a few small suggestions here and there.

• Add documentation and fix a bug from loop updates

• Updates to move some functionality to LauFitObject
• Update code after move to LauFitObject and extend to LauSimFitCoordinator
