refactor: MoveStr and integrate PushMove functionality.
#3
Conversation
Replaced the deprecated `MoveStr` with the more flexible `PushMove` API across tests and implementations. Enhanced `PushMove` to support additional options like prioritizing mainline moves. Improved position management in `Game` by aligning it with the move tree structure for better consistency.

Good improvement in error handling by directly returning the specific error from parseMoveText instead of wrapping it in a generic error message.

Remove deprecated pos field initialization
According to the PR objectives, the pos field is being deprecated in favor of using currentMove.position. However, line 26 still initializes the deprecated pos field.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 Codebase verification
Inconsistent ValidMoves() usage detected
The codebase shows inconsistent usage of ValidMoves():
- In pgn.go, there are still two instances using
p.game.pos.ValidMoves()that need to be updated top.game.ValidMoves() - The change in line 264 of pgn.go is correct, but similar changes are needed in lines where the old pattern is still used
🔗 Analysis chain
Verify all ValidMoves() calls are consistently updated
The change from p.game.pos.ValidMoves() to p.game.ValidMoves() aligns with the PR objectives of removing the deprecated pos field. Let's verify this change is consistent across the codebase.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for any remaining direct calls to pos.ValidMoves()
# We want to ensure all calls have been migrated to the new API
# Search for any remaining direct calls to pos.ValidMoves()
rg -l "pos\.ValidMoves\(\)"
# Search for the new pattern to confirm migration
rg -l "\.ValidMoves\(\)"
Length of output: 217
Script:
#!/bin/bash
# Let's examine the actual usage context of ValidMoves() in each file
# to determine if there are any inconsistencies
# Check pos.ValidMoves() usages with context
rg "pos\.ValidMoves\(\)" -B 2 -A 2
# Check .ValidMoves() usages with context
rg "\.ValidMoves\(\)" -B 2 -A 2
Length of output: 6928
Replaced MoveStr with PushMove in all test cases for consistency and flexibility with additional parameters. Updated game logic to include position evaluation after each move, improving the accuracy of game state validation.

612-612: Fix unused assignment to move; potential logic error
At line 612, the assignment move = existingMove is made, but move is not used afterward. This could lead to unexpected behavior, as move should reflect the existing move found. Ensure that the updated move is used in subsequent code, or remove the assignment if it's unnecessary.

🛠️ Refactor suggestion
Refactor CurrentPosition() to avoid using deprecated g.pos
The CurrentPosition() method uses the deprecated g.pos field when g.currentMove is nil. Since g.pos is slated for removal, consider initializing g.currentMove to g.rootMove in the game constructor or updating the logic to avoid relying on g.pos.

Updated the piece options pool to return a pointer to the slice, improving memory efficiency. Adjusted the usage of the slice in the generateOptions function to dereference the pointer, ensuring proper manipulation of the slice while maintaining its capacity. This change enhances performance and aligns with best practices for slice management in Go.
Replaced the deprecated
MoveStrwith the more flexiblePushMoveAPI across tests and implementations. EnhancedPushMoveto support additional options like prioritizing mainline moves. Improved position management inGameby aligning it with the move tree structure for better consistency.Summary by CodeRabbit
