From 0fcd2b03792618728d9e4a0775896ff8498b021a Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 21 May 2025 22:50:45 +0000 Subject: [PATCH] feat: Allow pasting board position from string Implements the ability to paste a full board position directly into the application using a 65-character string format. The string consists of 64 characters representing the board ('X' for black, 'O' for white, '-' for empty) followed by one character indicating the current player ('X' or 'O'). Changes include: - Added `PastePositionShortcut` (Alt+V) to handle clipboard input. - Modified `SetboardRequest` to accept a 64-char board string and current player color. - Updated `BoardNotifier` to use the new `SetboardRequest` for pasting and refactored the "arrange discs" mode to be compatible. - Added localization for the "Paste Position" shortcut label. - Added new unit tests for the shortcut and notifier logic.
