| Functions within namespaced systems are now registered on the world as `{namespace}_{functionName}` rather than `{namespace}_{systemName}_{functionName}`. This is more ergonomic and is more consistent with namespaced resources in other parts of the codebase (e.g. accessing tables in schemaful indexer). | ||

| If you have a project using the `namespace` key in your `mud.config.ts` or are manually registering systems and function selectors on a namespace, you will likely need to codegen your system interfaces (`pnpm build`) and update any calls to these systems through the world's namespaced function signatures. |

Is there a way to bubble this up as a breaking change aside from major tag?

major should be only breaking changes, no other way make it more prominent unfortunately

No suggestions yet but I wanna experiment with this a bit, think about what happens when you register multiple systems with the same name etc. Maybe document everything in tests if not already covered |
@alvrs and I chatted a bit about this IRL and we think it'll just end up with a compile error, because codegen will create interfaces for each system and those will get combined into a |
|
@qbzzt there might be a couple places in the docs we need to update with this! |
The compiler error is unfortunate, I wonder if we can surface something more helpful in codegen? Trying it locally I get: 
|
Hmm, those don't appear to be namespaced? But the compiler does communicate well enough that there's an overlap. We could def add more validation+errors to codegen. |
|
Random thought: Instead of Need to think on it more but maybe it would remove issues like this. Definitely out of scope for this PR! |
Oh, oops, they weren't. And you're right that the compiler error is pretty decent. |
The old format is `namespace_system_function`. The new format is `namespace__function`. This should be merged at the same time as #2160, which implements the change.
