From 90c971539c474f1f8b8acdce1700110c97fad270 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 7 Apr 2026 06:48:34 +0000 Subject: [PATCH 1/2] refactor(cmd): introduce command algebra with Binding::Sequence and unified primitives MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add Binding::Sequence to keymap for composing commands, then use it and parameterization to eliminate redundant command structs: - Unify MoveSelection/JumpToEdge/ScrollRows/PageScroll into Move - Merge ToggleGroupUnderCursor + ToggleColGroupUnderCursor → ToggleGroupAtCursor - Merge CommitCellEdit + CommitAndAdvanceRight → CommitAndAdvance - Merge CycleAxisForTile + SetAxisForTile → TileAxisOp - Merge ViewBackCmd + ViewForwardCmd → ViewNavigate - Delete SearchAppendChar/SearchPopChar (reuse AppendChar/PopChar with "search") - Replace SaveAndQuit/OpenRecordRow with keymap sequences - Extract commit_add_from_buffer helper for CommitCategoryAdd/CommitItemAdd - Add algebraic law tests (idempotence, involution, associativity) https://claude.ai/code/session_01Y9X6VKyZAW3xo1nfThDRYU --- src/command/cmd.rs | 802 +++++++++++++++++++++--------------------- src/command/keymap.rs | 45 ++- 2 files changed, 450 insertions(+), 397 deletions(-) diff --git a/src/command/cmd.rs b/src/command/cmd.rs index 0ec5ee7..88f5671 100644 --- a/src/command/cmd.rs +++ b/src/command/cmd.rs @@ -295,62 +295,60 @@ fn viewport_effects( effects } -#[derive(Debug)] -pub struct MoveSelection { - pub dr: i32, - pub dc: i32, - pub cursor: CursorState, +/// How to move the cursor. +#[derive(Debug, Clone)] +pub enum MoveKind { + /// Relative offset (dr, dc) — subsumes MoveSelection and ScrollRows. + Relative(i32, i32), + /// Jump to start of axis: `true` = row, `false` = col. + ToStart(bool), + /// Jump to end of axis: `true` = row, `false` = col. + ToEnd(bool), + /// Page scroll: +1 = down, -1 = up (delta computed from visible_rows). + Page(i32), } -impl Cmd for MoveSelection { - fn name(&self) -> &'static str { - "move-selection" - } - - fn execute(&self, _ctx: &CmdContext) -> Vec> { - let row_max = self.cursor.row_count.saturating_sub(1); - let col_max = self.cursor.col_count.saturating_sub(1); - let nr = (self.cursor.row as i32 + self.dr).clamp(0, row_max as i32) as usize; - let nc = (self.cursor.col as i32 + self.dc).clamp(0, col_max as i32) as usize; - viewport_effects( - nr, - nc, - self.cursor.row_offset, - self.cursor.col_offset, - self.cursor.visible_rows, - self.cursor.visible_cols, - ) - } -} - -/// Unified jump-to-edge: jump to first/last row or column. -/// `is_row` selects the axis; `end` selects first (false) or last (true). +/// Unified navigation command.
