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

Installing

From the command line

$ gem install puppet-lint-empty_string-check

In a Gemfile

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

Checks

Variable assigned to the empty string

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

What you have done

$foo = ''

What you should have done

$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.

Disabling the check

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')
