puppet-lint-undef_in_function-check

A DEPRECATED puppet-lint plugin to check for undef in function calls.

Installing

From the command line

$ gem install puppet-lint-undef_in_function-check

In a Gemfile

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

Checks

Undef passed to a function

When functions are called, undef is cast into an empty string. Passing undef to a function is most likely not what you mean to do.

Since the modern Puppet function API was introduced in Puppet 4, functions can now be passed undef and these parameters won't be cast to empty strings.

All new functions should be written using this API and older functions migrated to it.

Also considering that a puppet-lint plugin has no way of telling which API a function is written in, the use of this plugin is no longer recommended.

It is DEPRECATED and no longer maintained.

What you have done

somefunction(undef)

What you should have done

somefunction('')

Disabling the check

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

$ puppet-lint --no-undef_in_function_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_undef_in_function_assignment')
