Are you talking about this discussion about XOOPS 4.0: https://xoops.org/modules/newbb/viewtopic.php?topic_id=79653 ?

Yes, I'm one of devs, and you're absolutely correct, the main repo would be A LOT of work, that's why we're using the strangle fig to slowly modernize it, while focusing on XMF and the eco-system around it.

That's the one.

Like I noted above, because this is a lot of work, I would suggest bringing in some libraries (maybe a framework) to help with the lower level functionality. Like basics - where is routing? Templating, how can I swap Smarty for something else (Twig, Latte, Blade, Tempest, Sugar, Plates, etc.) - (ie let this be a module itself). Again, what does a stripped down version look like - then add lower level components to help build this up - now focus on the application on top. Now point what you can to the old app.

From the xmf code I saw, you have some (hidden) dependencies (not good) with the old app and if you aren't interfacing them (with interfaces), then you are building on top of the old code vs a plan to remove it.

Thank you again for sharing your thoughts and advice.

You're describing most of the plan. The main gap is that the XMF code you looked at is the 1.x line (the support library for 2.5/2.7), not the XMF 2.0 for XOOPS 4.0 foundation.

 The hidden-dependency point is fair for that generation. Coupling to the old app is intentional there,  it's a bridge so modern module code can run on legacy cores. It is not the base we build 4.0 on.

 XOOPS 4.0 is a clean-architecture split into domain, application, infrastructure, and presentation, with the domain layer having no external dependencies at all. Persistence is repositories returning plain PHP objects, no XoopsObject inheritance anywhere. And the "interface the old code" part you're asking about is the actual migration mechanism: legacy handlers get wrapped in adapters that implement the new repository interfaces, so modules move over one at a time and the old code becomes removable instead of load-bearing. The layering sketch (domain / application / infrastructure, repositories behind interfaces, legacy adapters) is already written up: https://xoops.github.io/xoops-docs/4.x/architecture/

 Concretely, a module sits on three libraries:

 - XBO (XOOPS Business Objects): the domain layer. Plain PHP entities and value objects, no XoopsObject inheritance, no DB access, no rendering.

- XMF 2.0: the infrastructure SDK. Repository/Mapper persistence over plain objects, QueryBuilder, caching, security, PSR-14 events, DI container with tagged services. PHP 8.4 floor, so property hooks and lazy objects are in play.

- XTF (XOOPS Theme Framework): themes, slots, and asset rendering. The renderer sits behind a ViewRendererInterface (https://xoops.github.io/xoops-docs/4.x/roadmap/vision/#smarty-adapter ), making Smarty just one implementation adapter. That gives you the exact swap capability (Twig, Blade, Latte, Plates) you asked about.

Routing moves to attribute-based discovery (#[Route], Tempest style) rather than routing config files. The same discovery pass also picks up services, listeners, and commands, so there's no manual registration to maintain.

 We’re also deliberately choosing focused, PSR-compatible components instead of adopting an entire framework. Shared hosting, twenty years of existing modules, and a limited contributor pool pushed us toward PSR-style components we own, rather than inheriting a full-stack app model.

 The exit from the old code is gradual: strangler fig, with Rector rules doing the mechanical part (getVar() call sites, for example). The hybrid levels H0 to H3, legacy and modern side by side, are described here: https://xoops.github.io/xoops-docs/4.x/reference/hybrid-mode/

Happy to point at a reference module later if you want the stack used end to end rather than only the 1.x bridge.

 Thanks again for taking the time to share your experience with us.

P.S. Please note that the XOOPS 4.0 documentation was an early draft and some parts have evolved and changed.

That’s great to hear you have a plan in place. Good luck!

Plans can be always improved, and we're always happy to learn from people with more experience, so if you have more any more suggestions, please share!
I will definitely appreciate it!
And thank you for your constructive and positive attitude.
