Cloning GitHub subfolder only

is it possible with AppVeyor to clone only a subfolder from the repo? We do not need the entire repo for our Windows build, and it would be a massive time improvement.

Perhaps similarly to how submodules are updated during install step. I have not seen how to prevent the entire repo from cloning though.

    I'll answer my own question.

    clone_script in .appveyor.yml overrides the default clone command, so you can do custom cloning there. See for an example.

    However, git does not provide an easy way to pull a subfolder, and there's some trickery required. We decided to delay the implementation to keep our build system simple and more maintainable, and would probably use subtrees or submodules as an alternative.

    Sorry to have missed your original ticket.
    Looks like you found the clone_script override option.
    I agree that submodules would be the simplest way to go if you want to break a large repo into smaller more manageable projects.
