Aider fails to make change after showing correct diffs

Issue

After a chat-mode ask I told aider to make the change, it showed diffs but didn't actually make the change even though diffs were correct.

The error is occurring because you're trying to capture a std::unique_ptr by value in a lambda function. std::unique_ptr cannot be copied, only moved.

To fix this, you have a few options:

 1 Capture by reference instead of by value:


 card_algorithms->enumerate_hands(Street::Type(target_street), [&](const std::vector<Card>& hole_cards, const std::vector<Card>& flop) {
     // ...
 });


 2 Use a raw pointer or reference in the capture:


 CardAlgorithms* card_algorithms_ptr = card_algorithms.get();
 card_algorithms_ptr->enumerate_hands(Street::Type(target_street), [=](const std::vector<Card>& hole_cards, const std::vector<Card>& flop) {
     // ...
 });


 3 If you need to capture other variables by value, you can use a mixed capture:


 card_algorithms->enumerate_hands(Street::Type(target_street), [&card_algorithms, =](const std::vector<Card>& hole_cards, const std::vector<Card>& flop) {
     // ...
 });


The same applies to the inner lambda where you're calling enumerate_street_range.

Choose the option that best fits your needs and the lifetime requirements of the objects you're capturing. Option 1 (capturing by reference) is usually the simplest if you're sure that card_algorithms
will remain valid for the entire lifetime of the lambda.

> /ask what about just making ti a shared pointer

Yes, using a std::shared_ptr instead of a std::unique_ptr is another valid solution. This would allow you to copy the pointer in the lambda capture. Here's how you can modify your code:

 1 First, change the declaration of card_algorithms in your HandRolloutTest class:


 std::shared_ptr<CardAlgorithms> card_algorithms;


 2 In the SetUp() function, initialize it like this:


 card_algorithms = std::make_shared<CardAlgorithms>(game_config);


 3 Now your lambda captures should work without modification:


 card_algorithms->enumerate_hands(Street::Type(target_street), [=](const std::vector<Card>& hole_cards, const std::vector<Card>& flop) {
     // ...
     card_algorithms->enumerate_street_range([=](const std::vector<Card>& opponent_hole_cards) {
         // ...
     }, Street::Type(0), Street::Type(target_street), reserved_cards);
 });


Using a std::shared_ptr allows multiple owners of the same object, which can be useful in scenarios where you need to share ownership or when you're unsure about the object's lifetime. However, it comes
with a small performance overhead due to reference counting.

If you decide to go this route, make sure to update any other parts of your code that might be expecting a unique_ptr.

> do that

Certainly! I'll modify the HandRolloutTest class to use a std::shared_ptr for card_algorithms. Here are the necessary changes:

src/tests/test_wml_rollout_calculator.cpp


 <<<<<<< SEARCH
     std::unique_ptr<CardAlgorithms> card_algorithms;
 =======
     std::shared_ptr<CardAlgorithms> card_algorithms;
 >>>>>>> REPLACE


src/tests/test_wml_rollout_calculator.cpp


 <<<<<<< SEARCH
         card_algorithms = std::make_unique<CardAlgorithms>(game_config);
 =======
         card_algorithms = std::make_shared<CardAlgorithms>(game_config);
 >>>>>>> REPLACE


These changes will allow you to capture card_algorithms by value in your lambda functions without causing compilation errors. The rest of your code should work as is with this modification.

Unrelated...Paul is there anything I can do to support the project? I have minimal time to contribute, are you accepting corporate donations?
