zureg attempts to read a configuration file from zureg.json and /etc/zureg.json.

zureg.example.json contains a skeleton. Most importantantly, you'll want to configure database.connectionString to point to a postgres database with write access.

zureg uses AWS SES to send emails.

To be able to send email to the registrants you will need to move your account out of the sandbox. For instructions how to do it, follow: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/request-production-access.html

This exports all attendees to a JSON file, that can be consumed by other tools. Typically you want to only export the Registered and Confirmed attendees.

zureg-export --state Registered --state Confirmed export.json

This emails all attendees using a mustache template. Usage:

zureg-email export.json template.txt statefile subject

statefile is any file where we can write emails to that have already been sent -- this way we can make sure no double emails are sent if when there are any issues if the program is killed our the SES API is being weird while sending.

Reads an export file and produces badges in HTML format that should print nicely.

zureg-badges \
    --badges-per-page 21
    --badge-width 70mm
    --badge-height 42.4mm
