Constructors

ActiveRepoRest CombineStrategy | rest repositories, i.e. not explicitly listed as `ActiveRepo`
ActiveRepo RepoName CombineStrategy | explicit repository name

organizeByRepos :: ActiveRepos -> (a -> RepoName) -> [a] -> Either String [(a, CombineStrategy)] #

Sort values `RepoName` according to `ActiveRepos` list.

    >>> let repos = [RepoName "a", RepoName "b", RepoName "c"]
    >>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge]) id repos
    Right [(RepoName "a",CombineStrategyMerge),(RepoName "b",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge)]

    >>> organizeByRepos (ActiveRepos [ActiveRepo (RepoName "b") CombineStrategyOverride, ActiveRepoRest CombineStrategyMerge]) id repos
    Right [(RepoName "b",CombineStrategyOverride),(RepoName "a",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge)]

    >>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge, ActiveRepo (RepoName "b") CombineStrategyOverride]) id repos
    Right [(RepoName "a",CombineStrategyMerge),(RepoName "c",CombineStrategyMerge),(RepoName "b",CombineStrategyOverride)]

    >>> organizeByRepos (ActiveRepos [ActiveRepoRest CombineStrategyMerge, ActiveRepo (RepoName "d") CombineStrategyOverride]) id repos
    Left "no repository provided d"

Note: currently if `ActiveRepoRest` is provided more than once, rest-repositories will be multiple times in the output.
