Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Add initializer_list to TPair and TMap request

There is initializer_list for TArray. It's great. I can do next:

 TArray<int32> = {1, 2, 3, 4, 5};

I think it would be nice works TMaps also:

 TMap<int32, FName> map = { {1, "Hi!"}, {2, "Yo!"}, {3, "Lolz"} };

It possible if TPair will be extended with constructor with key and value, and TMap with initializer_list.

Would be a great addition. I hate having to do Map.Add for each element.

It is possible like this:

 TMap<int32, float> map = { TPairInitializer<const int32&, const float&>(2, 5.f) };
