23 Dancer2::Template::Implementation::ForkedTiny is a reimplementation of
24 a subset of the functionality from Template Toolkit in as few lines of
25 code as possible.
26 It is intended for use in light-usage, low-memory, or low-cpu
28 templating situations, where you may need to upgrade to the full
29 feature set in the future, or if you want the retain the familiarity of
30 TT-style templates.
31 For the subset of functionality it implements, it has fully-compatible
33 template and stash API. All templates used with
34 Dancer2::Template::Implementation::ForkedTiny should be able to be
35 transparently upgraded to full Template Toolkit.
36 Unlike Template Toolkit, Dancer2::Template::Implementation::ForkedTiny
38 will process templates without a compile phase (but despite this is
39 still quicker, owing to heavy use of the Perl regular expression
40 engine.
41 SUPPORTED USAGE
43 By default, the "[% %]" tag style is used. You can change the start tag
44 and end tag by specifying them at object creation :
45 my $template = Dancer2::Template::Implementation::ForkedTiny->new(
47 start_tag => '<%',
48 end_tag => '%>,
49 );
50 In the rest of the documentation, "[% %]" will be used, but it can be
52 of course your specified start / end tags.
53 Both the "[%+ +%]" style explicit whitespace and the "[%- -%]" style
55 explicit chomp are support, although the "[%+ +%]" version is unneeded
56 in practice as Dancer2::Template::Implementation::ForkedTiny does not
57 support default-enabled "PRE_CHOMP" or "POST_CHOMP".
58 Variable expressions in the form "[% foo.bar.baz %]" are supported.
60 Appropriate simple behaviours for "ARRAY" references, "HASH" references
62 and objects are supported. "VMethods" such as [% array.length %] are
63 not supported at this time.
64 If the resulting expression is a CodeRef, it'll be evaluated.
66 "IF", "ELSE" and "UNLESS" conditional blocks are supported, but only
68 with simple "[% foo.bar.baz %]" conditions.
69 Support for looping (or rather iteration) is available in simple "[%
71 FOREACH item IN list %]" form is supported. Other loop structures are
72 not supported. Because support for arbitrary or infinite looping is not
73 available, Dancer2::Template::Implementation::ForkedTiny templates are
74 not turing complete. This is intentional.
75 All of the four supported control structures
77 "IF"/"ELSE"/"UNLESS"/"FOREACH" can be nested to arbitrary depth.
78 The treatment of "_private" hash and method keys is compatible with
80 Template Toolkit, returning null or false rather than the actual
81 content of the hash key or method.
82 Anything beyond the above is currently out of scope.

86 Dancer2::Template::Implementation::ForkedTiny - Template Toolkit
87 reimplemented in as little code as possible, forked from Template::Tiny
88
90 new
91 my $template = Dancer2::Template::Implementation::ForkedTiny->new(
92 TRIM => 1,
93 );
94 The "new" constructor is provided for compatibility with Template
96 Toolkit.
97 The only parameter it currently supports is "TRIM" (which removes
99 leading and trailing whitespace from processed templates).
100 Additional parameters can be provided without error, but will be
102 ignored.
103 process
105 # DEPRECATED: Return template results (emits a warning)
106 my $text = $template->process( \$input, $vars );
107 # Print template results to STDOUT
109 $template->process( \$input, $vars );
110 # Generate template results into a variable
112 my $output = '';
113 $template->process( \$input, $vars, \$output );
114 The "process" method is called to process a template.
116 The first parameter is a reference to a text string containing the
118 template text. A reference to a hash may be passed as the second
119 parameter containing definitions of template variables.
120 If a third parameter is provided, it must be a scalar reference to be
122 populated with the output of the template.
123 For a limited amount of time, the old deprecated interface will
125 continue to be supported. If "process" is called without a third
126 parameter, and in scalar or list contest, the template results will be
127 returned to the caller.
128 If "process" is called without a third parameter, and in void context,
130 the template results will be "print()"ed to the currently selected file
131 handle (probably "STDOUT") for compatibility with Template.
