NAME

       targetctl - Save and restore configuration of kernel target

DESCRIPTION

       targetctl  is  a  low-level script to save and restore the configuration of the LIO kernel target, to and from a file in json format. It is
       not normally meant to be used by end-users directly, but by system init frameworks, or advanced end-users who are generating the configura-
       tion file themselves and need a way to load the configuration without relying on the targetcli configuration shell.

USAGE

       targetctl must be invoked as root. Exit status will be 0 if successful, or nonzero if an error was encountered.

       targetctl save [config-file]

       Saves  the  current configuration of the kernel target to a file in json format. Since the file may contain cleartext passwords, the file's
       permissions will be set to only allow root access. If config-file is not supplied, targetctl will use the default file location,  /etc/tar-
       get/saveconfig.json.

       targetctl restore [config-file]

       Removes	any  existing configuration and replaces it with the configuration described in the file. See saveconfig.json(5) for more details.
       If parts of the configuration could not be restored, those parts will be noted in the error output, and the rest of the configuration  will
       still be applied.

       targetctl clear

       Removes any existing configuration from the running kernel target.

       targetctl --help

       Displays usage information.

NAME

       Mojolicious::Plugin::JSONConfig - JSON configuration plugin

SYNOPSIS

	 # myapp.json
	 {
	   "foo"       : "bar",
	   "music_dir" : "<%= app->home->rel_dir('music') %>"
	 }

	 # Mojolicious
	 my $config = $self->plugin('JSONConfig');

	 # Mojolicious::Lite
	 my $config = plugin 'JSONConfig';

	 # Reads "myapp.json" by default
	 my $config = app->config;

	 # Everything can be customized with options
	 my $config = plugin JSONConfig => {file => '/etc/myapp.conf'};

DESCRIPTION

       Mojolicious::Plugin::JSONConfig is a JSON configuration plugin that preprocesses it's input with Mojo::Template.

       The application object can be accessed via $app or the "app" function. You can extend the normal config file "myapp.json" with "mode"
       specific ones like "myapp.$mode.json". A default configuration filename will be generated by decamelizing the application class with
       "decamelize" in Mojo::Util or from the application filename.

       The code of this plugin is a good example for learning to build new plugins, you're welcome to fork it.

OPTIONS

       Mojolicious::Plugin::JSONConfig inherits all options from Mojolicious::Plugin::Config and supports the following new ones.

   "template"
	 # Mojolicious::Lite
	 plugin JSONConfig => {template => {line_start => '.'}};

       Attribute values passed to Mojo::Template object used to preprocess configuration files.

   "parse"
	 $plugin->parse($content, $file, $conf, $app);

       Process content with "render" and parse it with Mojo::JSON.

	 sub parse {
	   my ($self, $content, $file, $conf, $app) = @_;
	   ...
	   $content = $self->render($content, $file, $conf, $app);
	   ...
	   return $hash;
	 }

   "register"
	 my $config = $plugin->register($app, $conf);
