Extend the gutter with the last two of the framed modes (Q#UX4): - Relative: each line shows its distance from the cursor line (cursor = 0). - Hybrid: cursor line shows its absolute number, others relative (Vim number + relativenumber). `LineNumberMode` gains `Relative`/`Hybrid` + `number_for(line, cursor_line)` (the per-line displayed value) and `is_on()`. `paint_line_number_gutter` now derives each number from the mode and the cursor's buffer line (`text_view.line_at_offset(cursor)`); the TUI re-renders the whole frame on cursor motion, so relative numbers track the cursor for free. Gutter width is sized by `digits(line_count)` for every on-mode, so the text never jitters as the cursor moves. Mode selection (chosen over a 4-way cycle): `window.toggle-line-numbers` stays a binary off/absolute toggle; a new `window.set-line-numbers` opens the minibuffer with an arrow-navigable completion dropdown (off|absolute|relative|hybrid) to pick a mode directly. `set_line_numbers` accepts all four; the getter returns them. No protocol change here — the GPU half (which needs the mode over the wire, protocol v14) follows. Test: number_for across all modes. fmt + clippy clean both flavors; 1446 lib tests pass. Needs a TUI eyeball. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_014TXbAwk27agwhrNNrhLi2U |
