GemWatch¶ ↑

GemWatch helps sysadmins to watch their systems to see if an update is available for installed gems. GemWatch can watch all installed gems or only specified gems. Results can be outputted to stdout or email(s) addresses.

A cron task launching GemWatch with a configuration file can be used to launch checks every day.

Checks options:
    -u=<all|gem1, gem2, ...>         Precise what are the gems to check for the update.
        --check-update-on

Email options:
    -e=email1, email2, ...           Email address to send results.
        --email-recipient
    -s, --email-subject=subject      Subject used in the email.
    -f, --email-from=email           Email's sender.

SMTP options:
        --smtp-host=localhost        SMTP host to connect to send emails.
        --smtp-port=25               SMTP port to connect to send emails.

General options:
    -c, --config=config.yml          YAML configuration file. Overrides command line attributes.
    -S, --stdout                     Display results on stdout instead of mailing them.
    -h, --help                       Show this message

A yaml configuration file can be used to specify all options:

email:
  recipients: admin@example.com
  subject: Critical update !

smtp:
  host: 127.0.0.1
  port: 25

check:
  update_on: super_security, rails

$> gemwatch

Those gems can be updated to their latest version:
