Feature request: export publication

[miry]

@clawfire reported:

I would like to export articles from a publication (which has multiple users).

Could be medup -p smileinnovation for example.

Additional information about sample request to scrape publications with medup:

$ medup "https://medium.com/smileinnovation"  
Posts count: 1
GET https://medium.com/smileinnovation?format=json => 200 OK
ERROR: #<KeyError:Missing hash key: "value">
Missing hash key: "value" (KeyError)
  from ???
  from ???
  from ???

  from ???

With curl:

curl "https://medium.com/smileinnovation?format=json"                                                                                                                                                                                                                       
])}while(1);</x>{"success":true,"payload":{"collection":{"id":"b27cbdda139c","name":"Smile Innovation","slug":"smileinnovation"

I think user and publications could be parsed.

medup https://medium.com/... # Full url scrape single post or publications
medup @miry    # Detect that it is user with prefix @ and equal https://medium.com/@miry
medup smileinnovation # Equal to https://medium.com/smileinnovation

Explicit params could be also welcome to make sure user expects publications.

That would be awesome, since there's no way to ask an export for a publication from Medium.

@clawfire If you have time, can you check if it works for you:

$ git checkout 31-publications
$ crystal run src/cli.cr --error-trace -- -p smileinnovation -d posts/smileinnovation

or

$ git checkout 31-publications
$ rake build
$ ./_output/medup -p smileinnovation -d posts/smileinnovation
