From 210e9648bf0f1ef8c94609e64e009c59624890ea Mon Sep 17 00:00:00 2001 From: Orion Henry Date: Fri, 2 Sep 2022 09:53:49 -0500 Subject: [PATCH 1/5] The patch interface needs an accurate path per patch op For the path to be accurate it needs to be calculated at the moment of op insert not at commit. This is because the path may contain list indexes in parent objects that could change by inserts and deletes later in the transaction. The primary change was adding op_observer to the transaction object and removing it from commit options. The beginnings of a wasm level `applyPatch` system is laid out here. --- automerge-c/src/doc.rs | 2 +- automerge-wasm/index.d.ts | 3 + automerge-wasm/src/interop.rs | 153 ++++++++-

This `Observer` type is then used to handle patch generation logic. However, there are cases where we might not want an `OpObserver` and in these cases we can execute various things fast - so we need to have something like an `Option`. In order to track the presence or otherwise of the observer at the type level introduce `automerge::transaction::observation`, which is a type level `Option`.
