NAME

6       Dancer2::Template::TemplateToolkit - Template toolkit engine for
7       Dancer2
8

VERSION

10       version 0.301004
11

SYNOPSIS

13       To use this engine, you may configure Dancer2 via "config.yaml":
14
15           template:   "template_toolkit"
16
17       Or you may also change the rendering engine on a per-route basis by
18       setting it manually with "set":
19
20           # code code code
21           set template => 'template_toolkit';
22
23       Most configuration variables available when creating a new instance of
24       a Template::Toolkit object can be declared inside the template toolkit
25       section on the engines configuration in your config.yml file.  For
26       example:
27
28         engines:
29           template:
30             template_toolkit:
31               start_tag: '<%'
32               end_tag:   '%>'
33
34       (Note: "start_tag" and "end_tag" are regexes.  If you want to use PHP-
35       style tags, you will need to list them as "<\?" and "\?>".)  See
36       Template::Manual::Config for the configuration variables.
37
38       In addition to the standard configuration variables, the option
39       "show_private_variables" is also available. Template::Toolkit, by
40       default, does not render private variables (the ones starting with an
41       underscore). If in your project it gets easier to disable this feature
42       than changing variable names, add this option to your configuration.
43
44               show_private_variables: true
45
46       Warning: Given the way Template::Toolkit implements this option,
47       different Dancer2 applications running within the same interpreter will
48       share this option!

DESCRIPTION

51       This template engine allows you to use Template::Toolkit in Dancer2.
52

METHODS

54   render($template, \%tokens)
55       Renders the template.  The first arg is a filename for the template
56       file or a reference to a string that contains the template. The second
57       arg is a hashref for the tokens that you wish to pass to
58       Template::Toolkit for rendering.
59

ADVANCED CUSTOMIZATION

61       Template::Toolkit allows you to replace certain parts, like the
62       internal STASH (Template::Stash). In order to do that, one usually
63       passes an object of another implementation such as
64       Template::Stash::AutoEscaping into the constructor.
65
66       Unfortunately that is not possible when you configure Template::Toolkit
67       from your Dancer2 configuration file. You cannot instantiate a Perl
68       object in a yaml file.  Instead, you need to subclass this module, and
69       use the subclass in your configuration file.
70
71       A subclass to use the aforementioned Template::Stash::AutoEscaping
72       might look like this:
73
74           package Dancer2::Template::TemplateToolkit::AutoEscaping;
75           # or MyApp::
76
77           use Moo;
78           use Template::Stash::AutoEscaping;
79
80           extends 'Dancer2::Template::TemplateToolkit';
81
82           around '_build_engine' => sub {
83               my $orig = shift;
84               my $self = shift;
85
86               my $tt = $self->$orig(@_);
87
88               # replace the stash object
89               $tt->service->context->{STASH} = Template::Stash::AutoEscaping->new(
90                   $self->config->{STASH}
91               );
92
93               return $tt;
94           };
95
96           1;
97
98       You can then use this new subclass in your config file instead of
99       "template_toolkit".
100
101           # in config.yml
102           engines:
103             template:
104               TemplateToolkit::AutoEscaping:
105                 start_tag: '<%'
106                 end_tag:   '%>'
107                 # optional arguments here
108                 STASH:
109
110       The same approach should work for SERVICE (Template::Service), CONTEXT
111       (Template::Context), PARSER (Template::Parser) and GRAMMAR
112       (Template::Grammar). If you intend to replace several of these
113       components in your app, it is suggested to create an app-specific
114       subclass that handles all of them at the same time.
115
116   Template Caching
117       Template::Tookit templates can be cached by adding the "COMPILE_EXT"
118       property to your template configuration settings:
119
120           # in config.yml
121           engines:
122             template:
123               template_toolkit:
124                 start_tag: '<%'
125                 end_tag:   '%>'
126                 COMPILE_EXT: '.tcc' # cached file extension
127
128       Template caching will avoid the need to re-parse template files or
129       blocks each time they are used. Cached templates are automatically
130       updated when you update the original template file.
131
132       By default, cached templates are saved in the same directory as your
133       template. To save cached templates in a different directory, you can
134       set the "COMPILE_DIR" property in your Dancer2 configuration file.
135
136       Please see "Caching_and_Compiling_Options" in Template::Manual::Config
137       for further details and more caching options.
