SubWCRev equivalent required

I use SubWCRev with VBA and .NET to get information about files in my working copy. In particular I need .HasModifications and .IsSvnItem (-> .IsGitItem). For example I use this in a Start-Commit-Hook that extract VBA modules into text files.

Any chance to get a equivalent in TortoiseGIT? If not, is there another way to get these information?
