  -h, --help            show this help message and exit
  -d, --debug           Enable debug mode.
  -u DEEZER_ID [DEEZER_ID ...], --user DEEZER_ID [DEEZER_ID ...]
                        Retrieve new releases for DEEZER_ID. Can be multiple
                        DEEZER_ID.
  -m EMAIL, --mail EMAIL
                        Send all new releases found to EMAIL.

                        Send a personalized new releases digest to all
                        recipients of a Sendgrid contact list.
  -s NUMBER_OF_DAYS, --since NUMBER_OF_DAYS
                        Keep only the albums released since a given number of
                        days.
  -n, --no-mail         Do not send any email.

Sending a New Releases digest to one user

python3 the-release-note.py -u 5 -m mail@mail.com -s 7

This will send all albums from user ID 5's favourite artists, released in the past 7 days, to mail@mail.com.

Senging a personalize New Releases digest to all recipients from a contact list

First you will need to create a Contact List in your Sendgrid acccount. This contact list must come with 2 custom fields: deezer_user_id : It must be an integer and match a Deezer user's ID. frequency : It must be set to daily or weekly. This is the frequency at which the email will be sent. If not found, it will default to daily.

Now change the value of contact_list_id in modules/__init__.py to match your own contact list.

Once properly configured, run python3 the-release-note.py to send new releases for all recipients in the SendGrid contact list.

Alternatively, you can also specify the contact list ID through the command line: python3 the-release-note.py --contact-list <SENDGRID_CONTACT_LIST_ID>

Sending the digest on a regular basis

Set up a cron to run the script regularly.

e.g. To send the newsletter every day at 8am (change path accordingly):

0 8 * * * source <yourpath>/credentials.env ; <yourpath>/python3 <yourpath>/the-release-note.py >> <yourpath>/cron.log 2>&1

Note that for users with "weekly" preferences, it will only send the email on Friday, containing new releases from the past 7 days.

Debug mode

Run with -d or --debug to record debug log.

Filtered new released

Only Albums and Single with a valid tracklist will appear in the digest. In addition, some artists or albums are banned.

Banned artists

Some artists are banned from appearing in the digest. For instance, The Beatles are banned because they are unlikely to release any real new material. Unfortunately, new content with wrong release date is frequently delivered to Deezer, hence the necessity of this filter.

The list of banned artist is in models/banned_artists. To ban an artist, simply add one to the list echo The Beatles >> models/banned_artists

Stopwords

If a stopword appear in a new release title, the content will be filtered. This is done to prevent shitty content (e.g. Karaoke or cover version) to appear in the digest.

The list of stopwords is in models/stopwords. To add a stopword, simply add one to the list echo MY_STOPWORD >> models/stopwords

Troubleshooting

SSL issue with sendgrid

This worked for me..

pip3 install certifi
/Applications/Python\ 3.7/Install\ Certificates.command

Update with your Python path accordingly.
