puppet-lint-appends-check

A puppet-lint plugin to check that the append (+=) operator is unused.

Installing

From the command line

shell $ gem install puppet-lint-appends-check

In a Gemfile

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

Checks

Append operator use

Use of the append operator can lead to unexpected behavior.

What you have done

```puppet $ssh_users = [‘myself’, ‘someone’]

class test { $ssh_users += [‘someone_else’] } ```

What you should have done

```puppet $ssh_users = [‘myself’, ‘someone’, ‘someone_else’]

OR

$ssh_users = hiera(‘ssh_users’) ```

Auto fixing

There is not one way to properly fix this type of style error, so running puppet-lint’s fix feature will not have any effect.

Disabling the check

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

shell $ puppet-lint --no-appends-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.

ruby PuppetLint.configuration.send('disable_appends') ## Transfer Notice
