Lite version with fewer dependency

[yujunz]

We plan to integrate go-getter in kubernetes-sigs/kustomize#2169 since go-getter has everything we need in getting remote sources.

However, kustomize itself is integrated in kubectl which has dependency conflict with some modules used by go-getter.

I wonder if we can have a lite version of go-getter with fewer dependency, mainly stripping s3, gcs and cmd to reduce the transitive dependencies. (See yujunz@fc7e8cd). This will make go-getter easier to integrate in other tools as a library.

What do you think about it?

Hello there, thanks for opening; we currently started a v2 branch with some breaking changes, it is not tagged yet and if you want to: one option we were considering would be to split the getters into sub modules, the cmd pkg can also be into a different submodule. Would you like to start working on this ? I still have to learn/grasp on how everything works with modules, but we can gain some time in there 🙂.

For the v2, we carved out a new Request struct from the Client struct; the v2 can also tell where the file was put.

That sounds interesting. Yes, I can contribute some time to splitting go-getter into sub modules.

Could you elaborate a bit the goals and no goals v2 so that I can understand the context better. And if there is already some work going on. Where can I find more details and follow the progress? Thanks.

Everything is in the v2 https://github.com/hashicorp/go-getter/tree/v2 branch and the request/client splitting is already in there. The Packer project which I help maintain needed some features which were breaking changes so I made them. PRs are here: #230 #231 #232

I am also considering this other breaking change that some users requested already in #207 and #193

Actually I think it would be better to move the conversation to #193, closing this one. I'll recap there.
