Refactor library architecture

[akalongman]

This library has a few design problems and it is very hard to extend and improve functionality.

Small TODO and first steps:

• [ ] Change namespace to more relevant
• [ ] Use dependency injection and service container
• [ ] Drop abstract classes and static calls (mostly for Request and DB), or wrap them inside facades
• [ ] Introduce Config class and remove configuration logic from Telegram class
• [x] Remove Botan integration from core library and add as a package (?)
• [ ] Improve creating of custom commands

I forgot some details in current library implementation and I will have some questions. Lets discuss them in this thread

Not sure if some kind of simple event handlers or hooks wouldn't be better.

DB could be 100% add-on powered by events/hooks.

@php-telegram-bot/developers what is a point of call useGetUpdatesWithoutDatabase? We already have checks for DB::isDbConnected() in the https://github.com/php-telegram-bot/core/blob/master/src/Telegram.php#L332 Can anyone explain please?

[jacklul]

It was made that way so that running getUpdates without DB isn't default behaviour, forcing developer to take action before it can be used

@jacklul

forcing developer to take action before it can be used

maybe we should force developers via documentation and not via code?

Hi @akalongman

I honestly don't understand why the big redesign on v1. I though that was the whole idea of v2, to leave v1 pretty much as is and build v2 with a better base. Restructuring v1 will make it even more confusing/difficult for users, as they'll have to change all their code to adapt to this, and then later again for v2, when it's reched a stable point. Also all documentation snippets that have accumulated in the issues will be invalid, meaning there will potentially be a lot of new "repeat" issues popping up.

My idea was to just have a better DB management with an ORM implemented, so that at least the DB layer is more usable/extendable, especially when updating table structures etc.

Also I don't quite understand why another style guide change :confused:

Apart from that, this looks like a great base for v2 :grin:

When stable version is not released, any BC changes is normal and acceptable, but release version is not defined yet, we can name it anything :blush: Lets discuss this in the TG

Implementing of that in current codebase is almost impossible :disappointed:

In final I want to make code compatible with new PSR-12 coding standard

Apart from that, this looks like a great base for v2

@akalongman Well, I'm 100% fine with removing that method and using "no database" mode when DB is not connected by default.
