# org.das2.util.filesystem.GitLabFileSystem

GitLab-backed FileSystem for Das2.

 Intended URI forms:

   https://git.example.edu/group/subgroup/project/-/blob/main/path/to/file.txt
   https://git.example.edu/group/subgroup/project/-/tree/main/path/to/dir
   https://git.example.edu/group/subgroup/project

 Internal strategy:
   - parse the web URL into host + projectPath + optional ref + optional repoPath
   - if ref is missing, query project metadata and use default_branch
   - list directories with /api/v4/projects/:id/repository/tree
   - read files with /-/raw/{ref}/{path}
 
 This was written by ChatGPT, experimenting to get a cleaner implementation of the filesystem.  It is not in use.
