Description
It would be so nice to have a possibility to put wide-char objects along with narrow-char objects into Logging streams without creating separated versions like "logger"/"wlogger" for each type.
If I use both types simultaneously, I mean std::string and std::wstring, and I want to report everything into my log-file then I have a mess. I need EITHER to create separate logging-objects for each type OR convert one type into another.
For example, Google-test library allows mix wchar and char output for custom error message for ASSERT:
ASSERT_TRUE(false) << L"wide-message" << "narrow-message";
ASSERT_FALSE(true) << std::wstring(L"message") << std::string("message");
And it is so convenient!
Any stream operator overloading is not an option. If library claims to be convenient, it should not require some magic non-documented workarounds.
Thanks!
You can just always use wlogger. Just don't forget to setup a proper locale in the sink so that wide characters are converted to narrow chars correctly when storing to files.
You can also output wide strings to narrow loggers, but in this case you don't have the control over the locale in the stream.
