Is TextFieldState annotated with @optics as well?

[carbaj0]

yes

[simon.vergauwen]

Okay, seems we have some testing to do on the KSP plugin

[carbaj0]

in 1.2.4 version i have a generated field called
nullableValue, in version 2.0.0 it has disappeared

[simon.vergauwen]

What was nullableValue doing? We're cleaning up the DSL for Optics a bit.

[simon.vergauwen]

We're now generating Lens<Source, Focus?> for nullable types, such that you can erase its value.

nonNull is just to turn it into Optional<Source, Focus>

[carbaj0]

an example

[carbaj0]

this his the current

[carbaj0]

and maybe we need something like this, with the "?"

[simon.vergauwen]

We do have something like ? which is notNull and takes you from Lens<S, A?> to Optional<S, A>. Not sure why that second screenshot is red underlined though. Guess we need to add some failing tests for these casees.

[Alejandro Serrano.Mena]

this is one of the breaking changes in 2.0 -- fields of type T? now generate Lens<A, T?> instead of Optional<A, T>, so you can set them back to non-nullable

as Simon mentioned, the fix is to use notNull , which turns Lens<A, T?> into Optional<A, T>, if you need the 1.2.x behavior

[carbaj0]

Oh, I understand now. With this information, I can make it work like in previous versions. Thanks!

CourseState.level.notNull.name() set  level.value.toString()

//setter
CourseState.level.setNullable(state , null)
