From 42e37a571e75aaf4feb1717dfebe8cf215e535dd Mon Sep 17 00:00:00 2001 From: Michael Davis Date: Tue, 22 Nov 2022 21:28:49 -0600 Subject: Apply transactions to all views (#4733) * Add a test case for updating jumplists across windows * Apply transactions to all views on history changes This ensures that jumplist selections follow changes in documents, even when there are multiple views (for example a split where both windows edit the same document). * Leave TODOs for cleaning up View::apply * Use Iterator::reduce to compose history transactions Co-authored-by: Blaž Hrastnik Co-authored-by: Blaž Hrastnik --- helix-term/src/ui/editor.rs | 26 +++++++++++++++++++++++--- 1 file changed, 23 insertions(+), 3 deletions(-) (limited to 'helix-term/src/ui/editor.rs') diff --git a/helix-term/src/ui/editor.rs b/helix-term/src/ui/editor.rs index 6c8ee2d9..44f89b77 100644 --- a/helix-term/src/ui/editor.rs +++ b/helix-term/src/ui/editor.rs @@ -1337,7 +1337,9 @@ impl Component for EditorView { cx.editor.status_msg = None; let mode = cx.editor.mode(); - let (view, _) = current!(cx.editor); + let (view, doc) = current!(cx.editor); + let original_doc_id = doc.id(); + let original_doc_revision = doc.get_current_revision(); let focus = view.id; if let Some(on_next_key) = self.on_next_key.take() { @@ -1413,13 +1415,31 @@ impl Component for EditorView { let view = view_mut!(cx.editor, focus); let doc = doc_mut!(cx.editor, &view.doc); - view.ensure_cursor_in_view(doc, config.scrolloff); - // Store a history state if not in insert mode.
