puppet-lint-empty_string-check

A puppet-lint plugin to check for variables assigned to the empty string.

This repository is archived. It was designed to verify that modules for Puppet 3 work on Puppet 4 as well. Vox Pupuli also maintains puppet-lint-params_empty_string-check. That puppet-lint plugin only checks for class parameters with a String datatype and '' as default value.

$ gem install puppet-lint-empty_string-check

gem 'puppet-lint-empty_string-check', :require => false

The empty string is true in the future parser. undef should be used instead for a false value for strings.

$foo = ''

$foo = undef

Note: There are valid cases of assigning a variable to the empty string. You should use control comment to disable checks for these.

To disable this check, you can add --no-empty_string_assignment-check to your puppet-lint command line.

$ puppet-lint --no-empty_string_assignment-check path/to/file.pp

Alternatively, if you’re calling puppet-lint via the Rake task, you should insert the following line to your Rakefile.

PuppetLint.configuration.send('disable_empty_string_assignment')

This plugin was originally authored by Camptocamp. The maintainer preferred that Puppet Community take ownership of the module for future improvement and maintenance. Existing pull requests and issues were transferred over, please fork and continue to contribute here instead of Camptocamp.
