silly question, I can't print the sprite name....

[rudiHammad]

I am sure it must be something stupid by I am trying to print the name of a sprite and I don't know how

auto testSprite = Sprite::create(); testSprite->setName("fooo"); log("%s", testSprite->getName());

This prints simbols. and getName() doesn't have .c_str(), so I am not sure how I can't figure out something so simple.

thx

getName() returns std::string_view. if you want the raw string then you need to use the std::string_view::data() method. In this case though, it's best to cast it to a std::string first and then just use c_str(), to ensure it is null terminated.

Use std::string(testSprite.getName()).c_str().

of course... thanks.
what use then should we give to std::string_view? In theory it is preferable to use it instead of std::string because it's light weight right?

Sorry, I don't understand what you mean by that.

It's not theory, but you're right that it's "light weight", since it's just a read-only reference to data, and doesn't actually hold a copy of the data. Plenty of info online about it.

In your specific use-case above, you're attempting to use a function (log) that accepts a null terminated character sequence, which has nothing to do with std::string or std::string_view. The need to convert the string_view to a string first is because the string_view does not have a null terminator at the end of the text, and if you don't ensure there is a null terminator (which a std::string does have), then bad things can happen when using the log method.

Oh never mind what I meant, I understand now with your explanation.
Cool. I had no idea how the log function worked. Thanks

The problem here is the log function, which is just a wrapper for printf. Prefer using C++ printing such as std::cout or fmt::print that do support std::string_view

planed to replace ax::log with fmt in the future release
