Refactor command line options

[bjohas]

Maybe we should have verbs:

zotzen install
zotzen new -> create
zotzen link
zotzen push

zotzen -h says what those verbs do.

-h, --help Show this help message and exit.
-v, --version Show program's version number and exit.
--show Show the zotero, zenodo item information
--open Open the zotero and zenodo link after creation
--debug Enable debug logging
install Install the config for Zotero and Zenodo.
new Create a new pair of Zotero/Zenodo entries.
link
push

zotzen create -h

Create a new zotero and a new zenodo record and link them.

--title TITLE Title of the new entries (for --new).
--json JSON A Zotero json file to be used for the Zotero entry
(for --new).
--group GROUP Group ID for which the new item Zotero is to be
created (for --new).
--template TEMPLATE Path of the template to be used for creating Zenodo
record.

Enhancements:

• 1. It would be good if this 'autofilled' the needed fields on Zenodo with blanks. I.e., if not title/author is available, it just uses 'unknown'. This means the user can create a pair of records, and edit them, then do a sync.
• It would be good if there were options for adding the essential fields (title, authors, etc, ... see card on zenodo-cli create)
• zenodo-cli needs a *files argument , which may be a single Zenodo json record... we should check what it does and give an error message.

zotzen link -h

Link an existing zotero item to a new zenodo record or link it with with an existing zenodo record in the DOI.
zotero-item (one positional item)

--getdoi Generate a DOI for an existing Zotero item.
--zen ZEN Existing Zenodo record id of the item to be linked.

Either --getdoi or --zen are required.

Use cases:

• 1. You have a zotero item already, and you want to get a DOI for it.
• 2. You have a zotero item already and you have a zenodo item already, and you want to use the existing DOI for the zotero item.

(If the item has a Zenodo DOI already, an error message is displayed:

The Zotero item has a Zenodo DOI already. If you really want to link this to a new record in Zenodo, please manually remove the DOI first. You can use the --open option to open the Zotero/Zenodo items to make adjustments.)

(If the Zenodo item is linked against a different Zotero item: The Zenodo item is already linked with a different Zotero item. Do you want to proceed? y/n?)

zotzen push -h

--sync Sync metadata from zotero to zenodo.
[Rename to --metadata]

--push Push Zotero attachments to Zenodo.
[Rename to --attachments]

--type TYPE Type of the attachments to be pushed.
--publish Publish zenodo record.
One or more positional arguments (zotero items)

This option requires items to be linked already (e.g., using zotzen link).

(Error message if the item is unlinked: The Zotero item XYZ is not linked to a Zenodo item. Please link it first:

zotzen link XYZ --getdoi
zotzen link XYZ --zen 123
