Make Hypodermic Great Again! Autowiring constructors with dependencies which are not available at the compile time.

Hi everyone,

We love Hypodermic, and we're excited to use it in our project! However, we need your help.

Our team is transitioning from a C# background to a C++ project. Since we previously used Autofac with .NET, Hypodermic was a natural choice for us.

We like to organize our code into packages, which means we often build packages with abstract classes as dependencies known at compile time. Unfortunately, we're encountering exceptions related to not being able to autowire constructors when registering types for these dependencies.

To work around this, we're using registerInstanceFactory with lambdas. However, managing and maintaining thousands of such factories introduces a lot of "accidental complexity," and we’re looking for ways to simplify this process.

We understand that .NET's reflection capabilities make this easier, while C++ lacks a direct equivalent (for now). Are there any strategies to automate the registration of classes in our case? Could a preprocessor, code generation, or any other tool or approach help us avoid asking developers to manually write factories for every class?

Any advice or recommendations would be greatly appreciated!

Thanks in advance!

Hello, can you provide a sample where autowiring fails on your side?

Give me some time I will need to create the demo solution.
