Function Blocks Migration from 2.x to 3.0

[pedro-ricardo]

Now that release 3.0 is here ... it is very clear how much FB implementation has changed since 2.x.
Some one there in 4diac team had to do a work on parsing all FunctionBlock implementation from the previous version to the newest.
I have a similar issue, we have roughly 300 additional function blocks (accumulated since 4diac 1.9) that will need a similar migration.

Does some one in the 4diac team could share a script that could at least start this migration ? No warranty of course ...
I imagine that some sort of script helped updating the whole 4diac type library implementations.

I don't think we have one big script for doing such a translation, or @mx990? The reason is we gradually changed stuff and in each step performed the updates. Often either with more or less simple search replaces.

If you have composite, simple, basic fb or adapters, the best solution is to re-export them from 4diac IDE. I think also for SIFBs this will be the quickest solution and then add back your code. If you want you can share me one of these FBs also privately and I can have a look what would be the quickest solution or if there are some rules for search replace.

Ok, got it ... they are mostly SIFBs.
I'll export them using the IDE latest release candidate, start moving the code to the new executeEvent and also keeping an eye at the way of reaching for the Inputs and Outputs.

most things become easier.
now it is way easier to make Generic FBs,
Adapters are way easier,
but the first Moment the conversion can be hard.

But i took this as a Chance to cleanup my Code,
especially Event Handlers and so on.

[pedro-ricardo]

Yep, that will definitely happen, it would be a waste of time not to revisit some old implementations in the process 👍

As a little something to make up for the effort I wanted to point out that we really really hope that these API changes will be the last one for a longer tiime. That is also the reason we took so much time for it.
