These should be shown as datasette-jellyfish and datasette-vega since those are the names on PyPI.

Here's a clue as to where to get it from:

In [20]: mod, dist = pm.list_plugin_distinfo()[0]                                                                                                           

In [21]: print(str(dist.metadata))

Datasette plugin that adds a custom SQL function for haversine distances

Actually this is better:

In [26]: dist.project_name                                                                                                                                  
Out[26]: 'datasette-haversine'

Couldn't easily write a test for this as plugin tests don't currently work against packaged plugins.

Here's the new datasette plugins output:

$ datasette plugins
[
    {
        "name": "datasette-cluster-map",
        "static": true,
        "templates": false,
        "version": "0.6"
    },
    {
        "name": "datasette-json-html",
        "static": false,
        "templates": false,
        "version": "0.5"
    },
    {
        "name": "datasette-vega",
        "static": true,
        "templates": false,
        "version": "0.6.2"
    }
]

Same output from /-/plugins
