NAME

       Dancer::Template::Simple - pure Perl 5 template engine for Dancer

DESCRIPTION

       This template engine is provided as a default one for the Dancer micro framework.

       This template engine should be fine for development purposes but is not a powerful one, it's written in pure Perl and has no C bindings to
       accelerate the template processing.

       If you want to power an application with Dancer in production environment, it's strongly advised to switch to
       Dancer::Template::TemplateToolkit.

SYNTAX

       A template written for Dancer::Template::Simple should be working just fine with Dancer::Template::TemplateToolkit. The opposite is not
       true though.

       variables
	   To interpolate a variable in the template, use the following syntax:

	       <% var1 %>

	   If 'var1' exists in the tokens hash given, its value will be written there.

NAME

       Dancer::ModuleLoader - dynamic module loading helpers for Dancer core components

SYNOPSIS

       Taken directly from Dancer::Template::TemplateToolkit (which is core):

	   die "Template is needed by Dancer::Template::TemplateToolkit"
	     unless Dancer::ModuleLoader->load('Template');

	   # we now have Template loaded

DESCRIPTION

       Sometimes in Dancer core we need to use modules, but we don't want to declare them all in advance in compile-time. These could be because
       the specific modules provide extra features which depend on code that isn't (and shouldn't) be in core, or perhaps because we only want
       these components loaded in lazy style, saving loading time a bit. For example, why load Template (which isn't required by Dancer) when you
       don't use Dancer::Template::TemplateToolkit?

       To do such things takes a bit of code for localizing $@ and "eval"ing. That code has been refactored into this module to help Dancer core
       developers.

       Please only use this for Dancer core modules. If you're writing an external Dancer module (Dancer::Template::Tiny, Dancer::Session::Cookie,
       etc.), please simply ""use ModuleYouNeed"" in your code and don't use this module.

METHODS
/SUBROUTINES
   load
       Runs a ""use ModuleYouNeed"".

	   use Dancer::ModuleLoader;
	   ...
	   Dancer::ModuleLoader->load('Something')
	       or die "Couldn't load Something
";

	   # load version 5.0 or more
	   Dancer::ModuleLoader->load('Something', '5.0')
	       or die "Couldn't load Something
";

	   # load version 5.0 or more
	   my ($res, $error) = Dancer::ModuleLoader->load('Something', '5.0');
	   $res or die "Couldn't load Something : '$error'
";

       Takes in arguments the module name, and optionally the minimum version number required.

       In scalar context, returns 1 if successful, 0 if not.  In list context, returns 1 if successful, "(0, "error message")" if not.

       If you need to give argumentto the loading module, please use the method "load_with_params"

   require
       Runs a ""require ModuleYouNeed"".

	   use Dancer::ModuleLoader;
	   ...
	   Dancer::ModuleLoader->require('Something')
	       or die "Couldn't require Something
";
	   my ($res, $error) = Dancer::ModuleLoader->require('Something');
	   $res or die "Couldn't require Something : '$error'
";

       If you are unsure what you need ("require" or "load"), learn the differences between "require" and "use".

       Takes in arguments the module name.

       In scalar context, returns 1 if successful, 0 if not.  In list context, returns 1 if successful, "(0, "error message")" if not.

   load_with_params
       Runs a ""use ModuleYouNeed qw(param1 param2 ...)"".

	   use Dancer::ModuleLoader;
	   ...
	   Dancer::ModuleLoader->load('Something', qw(param1 param2) )
	       or die "Couldn't load Something
";

	   my ($res, $error) = Dancer::ModuleLoader->load('Something', @params);
	   $res or die "Couldn't load Something : '$error'
";

       Takes in arguments the module name, and optionally parameters to pass to the import internal method.

       In scalar context, returns 1 if successful, 0 if not.  In list context, returns 1 if successful, "(0, "error message")" if not.

   use_lib
       Runs a ""use lib qw(path1 path2)"" at run time instead of compile time.

	   use Dancer::ModuleLoader;
	   ...
	   Dancer::ModuleLoader->use_lib('path1', @other_paths)
	       or die "Couldn't perform use lib
";

	   my ($res, $error) = Dancer::ModuleLoader->use_lib('path1', @other_paths);
	   $res or die "Couldn't perform use lib : '$error'
";

       Takes in arguments a list of path to be prepended to @INC, in a similar way than "use lib". However, this is performed at run time, so the
       list of paths can be generated and dynamic.

       In scalar context, returns 1 if successful, 0 if not.  In list context, returns 1 if successful, "(0, "error message")" if not.

   class_from_setting
       Given a setting in Dancer::Config, composes the class it should be.

       This is the function that translates:

	   # in config.yaml
	   template: "template_toolkit"

       To the class:

	   Dancer::Template::TemplateToolkit

       Example:

	   use Dancer::ModuleLoader;
	   my $class = Dancer::ModuleLoader->class_from_setting(
	       'Dancer::Template' => 'template_toolkit',
	   );

	   # $class == 'Dancer::Template::TemplateToolkit

	   $class = Dancer::ModuleLoader->class_from_setting(
	       'Dancer::Template' => 'tiny',
	   );

	   # class == 'Dancer::Template::Tiny
