Minor Changes

• a764f17: Add onExitFailureToOnError style suggestion: it reports an Effect.onExit callback that only acts on failure (Exit.isFailure, Exit.isSuccess, exit._tag checks, in a conditional, if or switch, with Effect.void on the other side) and recommends Effect.onError, which expresses the same intent more directly.

  program.pipe(
    Effect.onExit((exit) =>
      Exit.isFailure(exit) ? Effect.logError("failed", { cause: exit.cause }) : Effect.void
    )
  )
  // can be written as
  program.pipe(Effect.onError((cause) => Effect.logError("failed", { cause })))

Patch Changes

• ec499f2: Move fix-only work out of rule analysis into the quick fixes, so it runs only when the editor asks for code actions instead of on every check. This covers 27 rules, among them yieldInCallArgument, failCauseToConstructor, suspendFailToFailSync, catchTagToCatchReason, mapMapErrorToMapBoth and unnecessaryEffectGen. Their diagnostics are unchanged.

  Three rules now report explicitly typed calls that they used to skip, because those calls can still be rewritten by hand. They get no quick fix:

  • provideLayerSucceedToProvideService: Effect.provide(Layer.succeed<I, S>(Service, implementation)) (rewrite: Effect.provideService<I, S>(Service, implementation)), and the same for Layer.effect<…>
  • provideMergeAllToArray: Effect.provide<…>(Layer.mergeAll(...)) and Effect.provide(Layer.mergeAll<…>(...))
  • timeoutCatchTagToTimeoutOrElse: explicit type arguments on the Effect.timeout step

  // now reported, without a quick fix
  program.pipe(Effect.provide(Layer.succeed<Service, { readonly value: number }>(Service, implementation)))

• 7aacb7d: Update the TypeScript next tag to typescript@next, which ships typescript-go commit b7917e5e4c278f132ed19f777d968b6b1180fc24, update the TypeScript beta tag to typescript@beta, and update the TypeScript latest tag to typescript@latest.
