@reeganviljoen thoughts on my comment from my review above?
As a bigger question: what happens if one turns this on for their app and then wants to use a gem that provides ViewComponents that use helpers?
One thought on naming.

@joelhawksley I don't think this will break any existing gems, unless the user enables the config, however if the user does, it might not work unless the gem documents which helpers are used so the user can add them themselves with the use_helpers method
I do think this is a positive improvement however, as just adding helpers increases coupling to global state, which I feel is bad and is against the whole point of view_component. If a gem wants to add helpers they should let the user decide what helpers and how much coupling to global state they want
If a gem providing ViewComponents uses helpers, I'm not sure we should mandate that it's subject to strict_helpers
in the same way as the rest of the app.
Gems providing components that use helpers would need to be updated to use the new syntax, and waiting on providers to do that doesn't feel like an ideal experience for devs using ViewComponent to me. It's absolutely something gem maintainers should do post-haste, but I think configuration could make the transition period easier for consumers of these gems.
I can see us going a few different ways with this:
strict_helpers
enforces this for gems too. Making this available as an option would be good, but I don't think it should be the only one.strict_helpers
. This could allow folks the flexibility to allowlist on a gem-by-gem basis, or report strict helper violations (e.g. to an error reporting platform/in logs). I'd like to see this become something we do more often potentially. If we introduce configuration that controls a breaking change, this would be good to allow folks to understand (through their test suite or at runtime) where changes need to be made. I'm sure there are options beyond that, but that's what comes to mind right now. Any thoughts?
@boardfish thanks for sharing your concerns- I generally agree with you.
I think we might be better off having this be a macro folks can set on a component, likely on their ApplicationComponent.
@joelhawksley @boardfish noted, I wills see if I can work on something to macro based system working

What are you trying to accomplish?
Add a
config.view_component.strict_helpers_enabled
mode to view component which will throw anViewComponent::StrictHelperError
whenhelpers.<some_helper>
is used.This
What approach did you choose and why?
Anything you want to highlight for special attention from reviewers?
