In quite a few places the selection is changed multiple times in a transaction. For example, `backspace` might do it 3 times: * `select_autoclose_pair` * selection of the ranges to delete * `insert` of empty string also updates selection Before this change, each of these selection changes appended to selection history and did a bunch of work that's only relevant to selections the user actually sees. So for each backspace, `editor::UndoSelection` would need to be invoked 3-4 times before the cursor actually moves. It still needs to be run twice after this change, but that is a separate issue. Signature help even had a `backspace_pressed: bool` as an incomplete workaround, to avoid it flickering due to the selection switching between being a range and being cursor-like. The original motivation for this change is work I'm doing on not re-querying completions when the language server provides a response that has `is_incomplete: false`. Whether the menu is still visible is determined by the cursor position, and this was complicated by it seeing `backspace` temporarily moving the head of the selection 1 character to the left. This change also removes some redundant uses of `push_to_selection_history`. Not super stoked with the name `DeferredSelectionEffectsState`. Naming is hard. Release Notes: - N/A |
