I usually separate template class definitions in 3 files, a .h for declaration, a .cpp for method definition and a .hpp for "template-dependent" method definitions. Standard procedure.
I understand its best to keep the .hpp file to a minimum (to avoid code bloating, long preprocess times, etc.). Bu I'm lazy so I usually just put everything in the .cpp file to start with, and then move the definitions to the .hpp every time there's a compilation error.
My question is this:
How am I going to know in advance what I have to put in the .hpp file?
I understand what a compilation unit is, and I understand why some definitions are needed at compile-time, but I can't seem to apply theory to actual cases.
Could someone break it down the simple way for me?
What's an official terminology for those methods that need to be defined in the .hpp file. I don't like that "template-dependent" I used earlier
