- `ContentsManager.pre_save_hook` runs on the path and model with content
- `FileContentsManager.post_save_hook` runs on the filesystem path and model without content
- use pre_save_hook for things like stripping output
- use post_save_hook for things like nbconvert --to python
- start with no number (Untitled0 -> Untitled.ipynb)
- copy of copy increments instead of adding another `-Copy` (copy Foo-Copy1.ipynb gives Foo-Copy2.ipynb, not Foo-Copy1-Copy1.ipynb)
- copy file to new folder starts with the original filename, instead of unconditional `-Copy0`
- various docstrings, comments clarified and updated
- misc typos
- fix and test creating an untitled directory via POST
- only define `message` if there's something to say
- path is full path (including name)
- name is only used for read-only convenience, and plays no role in any API
- remove 'untitled upload' (POST with content and no path)
- failed validation doesn't prevent save/load,
but the user is now warned about it.
- there is now a warning dialog if fromJSON fails,
rather than the usual silent failure.
- clarified docstrings and errors
- still more notebook/file renames
- configurable untitled names
- copy_from can be full path
- fix running, upload, new-tab behaviors in dashboard
Yay, review!
