[question] Porting 1.x imports() to 2.0

I’m following Conan migration guide to 2.0. It contains the following recommended pattern that I expected to work everywhere:

from conan.tools.files import copy

def generate(self):
    for dep in self.dependencies.values():
        copy(self, "*.dylib", dep.cpp_info.libdirs[0], self.build_folder)
        copy(self, "*.dll", dep.cpp_info.libdirs[0], self.build_folder)

Unfortunately self.build_folder is set only in 2.0 and is None in 1.x so for 1.x I have to use self.build_folder that in turn doesn’t exist in 2.0. The following code works:

    def generate(self):
        cpp_info = self.dependencies["some_dependency"].cpp_info
        dst = self.build_folder if self.build_folder else self.folders.build
        rootpath = os.path.dirname(cpp_info.bindirs[0])
        copy(self, "*.dat", rootpath, dst=dst)

but I would prefer something working out of the box. BTW, why rootpath attribute is excluded from the new dependency model?

• I’ve read the CONTRIBUTING guide.

Hi @db4, Sorry for the delay in answering back. Yes, after seeing your use case, I think it makes sense that this is available in the test_package as well. I’ll mark this for the next release to have a look. Thanks!
