We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

Puppet sdiff module

A puppet module for suppressing diff output based on file and line patterns


Install in your puppet master's modulepath as a directory named 'sdiff'. This will use the defaults or hiera if it has been configured.

include sdiff

You will need to add the following to your puppet.conf on each agent



For use with Hiera simply configure the following keys:

sdiff::file_pattern: '\.env'
sdiff::line_pattern: 'MERCHANT_ID=.*\|PRIVATE_KEY=.*\$'

If you want to pass in the values to the module, that is done as below:

class { 'sdiff':
  color        => false,
  file_pattern => '\.env',
  line_pattern => 'MERCHANT_ID=.*\|PRIVATE_KEY=.*\$',

When a file pattern is matched, sdiff will change

Line supression works similar but will only suppress matching lines.
