From 690af2370dede57750ea077fcc69ae39d524ab37 Mon Sep 17 00:00:00 2001 From: Yanuo Ma Date: Wed, 4 Mar 2026 15:03:37 -0500 Subject: [PATCH 1/8] feat: toggle between inline and side-by-side layout (t key) Add ability to toggle diff layout while a session is open. Uses the existing single_pane mechanism for A/D files and rerender_current() to replay the current file selection in the new layout. - toggle.lua: orchestrates layout switch (normalize windows, rerender) - explorer/history: rerender_current() + current_selection + opts.force - side_by_side/inline_view: layout identity guards, window validity guards - keymaps: fresh buffer refs at execution time (stale closure fix) -

Date: Wed, 4 Mar 2026 15:03:52 -0500 Subject: [PATCH 2/8] refactor: remove display_state/diff_config, dead code, rename for consistency MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove display_state, diff_config, and their helpers (set_display_state, copy_session_config, build_single_file_state) — toggle works purely through existing session fields + rerender_current() - Remove reset_diff_panes (dead code — unreachable fallback) - Rename show_placeholder → reset_diff_panes (removed) - Rename rerender_current_source → rerender_current_file - Remove show_single_file_preview (dead code, no callers) - Remove current_layout private wrapper (inlined) - Change default toggle keymap from gl to t - Fix toggle rollback: always commit layout change, no desync Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- lua/codediff/config.lua | 2 +- lua/codediff/ui/explorer/render.lua | 7 +- lua/codediff/ui/history/render.lua

On Windows where git is slower, the async chain (git apply → callback → refresh → status → render) never finishes. Fix: use pure event-loop spin (vim.wait with return false) for all hunk operation tests (stage, unstage, discard) to let the full async chain complete without blocking.
