From 9991b5f4a0e0609252097a8537b759eb95186600 Mon Sep 17 00:00:00 2001 From: Cal Corum Date: Wed, 29 Oct 2025 01:15:11 -0500 Subject: [PATCH] CLAUDE: Refactor dice rolling into reusable utility module and add /d20 command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created utils/dice_utils.py with reusable dice rolling functions - DiceRoll dataclass for roll results - parse_and_roll_multiple_dice() for multiple dice notation - parse_and_roll_single_dice() for single dice notation - Graceful error handling with empty list returns - Refactored commands/dice/rolls.py to use new utility module - Removed duplicate DiceRoll class and parsing methods - Updated all method calls to use standalone functions - Added new /d20 command for quick d20 rolls - Fixed fielding prefix command to include d100 roll - Updated tests/test_commands_dice.py - Updated imports to use utils.dice_utils - Fixed all test calls to use standalone functions - Added comprehensive test for /d20 command - All 35 tests passing - Updated utils/CLAUDE.md documentation - Added Dice Utilities section with full API reference - Documented functions, usage patterns, and design benefits - Listed all commands using dice utilities Benefits: - Reusability: Dice functions can be imported by any command file - Maintainability: Centralized dice logic in one place - Testability: Functions testable independent of command cogs - Consistency: All dice commands use same underlying logic 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- commands/dice/rolls.py | 111 +++++++------------ tests/test_commands_dice.py | 72 +++++++----- utils/CLAUDE.md | 213 +++++++++++++++++++++++++++++++++++- utils/dice_utils.py | 84 ++++++++++++++ 4 files changed, 383 insertions(+), 97 deletions(-) create mode 100644 utils/dice_utils.py diff --git a/commands/dice/rolls.py b/commands/dice/rolls.py index b000844..a4d8752 100644 --- a/commands/dice/rolls.py +++ b/commands/dice/rolls.py @@ -4,9 +4,7 @@ Dice Rolling Commands Implements slash commands for dice rolling functionality required for gameplay.
