Problem adding if blocks inside a location using location_cfg_append/prepend

[mezezo]

Trying to add an if block inside an ginx::resource::location using location_cfg_append/prepend does not work as a trailing ; is appended to the closing }.

nginx::resource::location{ 'resources':
    location            => '/assets/',
    vhost               => $webserver_hostname,
    location_alias      => $versioned_assets,
    location_cfg_append => {
      'if'              => '($args ~ "debug=y") {
        rewrite .* /index.debug.html last;
      }',
      'try_files'       => '$uri /index.html',
      'expires'         => 'epoch',
    }
}

Looking at the generated conf file I can clearly see that a ; is after the closing } and nginx complains about it

Error: /Stage[main]/Nginx::Service/Service[nginx]: Could not restart Service[nginx]: Execution of '/sbin/service nginx restart' returned 1: nginx: [emerg] unexpected ";" in /etc/nginx/sites-enabled...

What is the right way to add an if block inside a location element?

Use location_custom_cfg_append instead. It doesn't add the trailing ;.

If you do replace your location_cfg_append with location_custom_cfg_append you'll have to manually add the trailing ; to every directive (i.e. your try_files, expires)

There's also raw_append which lets you add an array of lines you want added to the config verbatim.
