From 99cee8778cc7c6ee9ddd405f5f00caa713299d68 Mon Sep 17 00:00:00 2001 From: Alvaro Parker <64918109+AlvaroParker@users.noreply.github.com> Date: Mon, 25 Aug 2025 16:18:03 -0400 Subject: [PATCH] tab_switcher: Add support for diagnostics (#34547) Support to show diagnostics on the tab switcher in the same way they are displayed on the tab bar. This follows the setting `tabs.show_diagnostics`. This will improve user experience when disabling the tab bar and still being able to see the diagnostics when switching tabs Preview: Screenshot From 2025-07-16 11-02-42 Release Notes: - Added diagnostics indicators to the tab switcher --------- Co-authored-by: Kirill Bulatov --- crates/language/src/buffer.rs | 20 +++-- crates/project/src/lsp_store.rs | 23 +++-- crates/tab_switcher/src/tab_switcher.rs | 114 +++++++++++++++++------- 3 files changed, 108 insertions(+), 49 deletions(-) diff --git a/crates/language/src/buffer.rs b/crates/language/src/buffer.rs index b106110c33..4ddc2b3018 100644 --- a/crates/language/src/buffer.rs +++ b/crates/language/src/buffer.rs @@ -1569,11 +1569,21 @@ impl Buffer { self.send_operation(op, true, cx);
