Select() equivalent in MODULE.bazel

[ScottHo]

Is it possible to have some sort of switch in MODULE.bazel files?

I'm using conan, and have different use_repo() calls for linux and windows

Is there a way to toggle between these two calls?
use_repo(load_conan_dependencies, "linux_lib", "common_lib", ...)
use_repo(load_conan_dependencies, "windows_lib", "common_lib", ...)

The current answer is no. There is no conditional dependency support in MODULE.bazel. You could have the load_conan_dependencies module extension generate different repo for the same repo name and mark it as os_dependent and use

use_repo(load_conan_dependencies, "platform_specific_lib", "common_lib", ...)

But then your lockfile has to be updated separately on each platfrom.

If possible, try to generate repos for each platform regardless of what the host machine is and then use select in BUILD files. This is much more flexible and also works better with multi-platform builds.

Thanks for the replies. What I ended up doing is generating a MODULE.bazel when I generate the dependencies form conan, and using the import() statement
