From e11e7df724d1c959ec63de94b65c351916c291b1 Mon Sep 17 00:00:00 2001 From: Kirill Bulatov Date: Sat, 29 Mar 2025 00:04:16 +0200 Subject: [PATCH] Restore editor state on reopen (#27672) Closes https://github.com/zed-industries/zed/issues/11626 Part of https://github.com/zed-industries/zed/issues/12853 `"restore_on_file_reopen": true` in workspace settings can now be used to enable and disable editor data between file reopens in the same pane: https://github.com/user-attachments/assets/8d938ee1-d854-42a8-bbc3-2a4e4d7d5933 The settings are generic and panes' data store can be extended for further entities, beyond editors. --------------- Impl details: Currently, the project entry IDs seem to be stable across file reopens, unlike BufferIds, so those were used. Originally, the DB data was considered over in-memory one as editors serialize their state anyway, but managing and exposing PaneIds out of the DB is quite tedious and joining the DB data otherwise is not possible.
