NAME

6       Template::Tiny - Template Toolkit reimplemented in as little code as
7       possible
8

SYNOPSIS

10         my $template = Template::Tiny->new(
11             TRIM => 1,
12         );
13
14         # Print the template results to STDOUT
15         $template->process( <<'END_TEMPLATE', { foo => 'World' } );
16         Hello [% foo %]!
17         END_TEMPLATE
18

DESCRIPTION

20       Template::Tiny is a reimplementation of a subset of the functionality
21       from Template Toolkit in as few lines of code as possible.
22
23       It is intended for use in light-usage, low-memory, or low-cpu
24       templating situations, where you may need to upgrade to the full
25       feature set in the future, or if you want the retain the familiarity of
26       TT-style templates.
27
28       For the subset of functionality it implements, it has fully-compatible
29       template and stash API. All templates used with Template::Tiny should
30       be able to be transparently upgraded to full Template Toolkit.
31
32       Unlike Template Toolkit, Template::Tiny will process templates without
33       a compile phase (but despite this is still quicker, owing to heavy use
34       of the Perl regular expression engine.
35
36   SUPPORTED USAGE
37       Only the default "[% %]" tag style is supported.
38
39       Both the "[%+ +%]" style explicit whitespace and the "[%- -%]" style
40       explicit chomp are support, although the "[%+ +%]" version is unneeded
41       in practice as Template::Tiny does not support default-enabled
42       "PRE_CHOMP" or "POST_CHOMP".
43
44       Variable expressions in the form "[% foo.bar.baz %]" are supported.
45
46       Appropriate simple behaviours for "ARRAY" references, "HASH" references
47       and objects are supported. "VMethods" such as [% array.length %] are
48       not supported at this time.
49
50       "IF", "ELSE" and "UNLESS" conditional blocks are supported, but only
51       with simple "[% foo.bar.baz %]" conditions.
52
53       Support for looping (or rather iteration) is available in simple "[%
54       FOREACH item IN list %]" form is supported. Other loop structures are
55       not supported. Because support for arbitrary or infinite looping is not
56       available, Template::Tiny templates are not turing complete. This is
57       intentional.
58
59       All of the four supported control structures
60       "IF"/"ELSE"/"UNLESS"/"FOREACH" can be nested to arbitrary depth.
61
62       The treatment of "_private" hash and method keys is compatible with
63       Template Toolkit, returning null or false rather than the actual
64       content of the hash key or method.
65
66       Anything beyond the above is currently out of scope.

METHODS

69   new
70         my $template = Template::Tiny->new(
71             TRIM => 1,
72         );
73
74       The "new" constructor is provided for compatibility with Template
75       Toolkit.
76
77       The only parameter it currently supports is "TRIM" (which removes
78       leading and trailing whitespace from processed templates).
79
80       Additional parameters can be provided without error, but will be
81       ignored.
82
83   process
84         # DEPRECATED: Return template results (emits a warning)
85         my $text = $template->process( \$input, $vars );
86
87         # Print template results to STDOUT
88         $template->process( \$input, $vars );
89
90         # Generate template results into a variable
91         my $output = '';
92         $template->process( \$input, $vars, \$output );
93
94       The "process" method is called to process a template.
95
96       The first parameter is a reference to a text string containing the
97       template text. A reference to a hash may be passed as the second
98       parameter containing definitions of template variables.
99
100       If a third parameter is provided, it must be a scalar reference to be
101       populated with the output of the template.
102
103       For a limited amount of time, the old deprecated interface will
104       continue to be supported. If "process" is called without a third
105       parameter, and in scalar or list contest, the template results will be
106       returned to the caller.
107
108       If "process" is called without a third parameter, and in void context,
109       the template results will be "print()"ed to the currently selected file
110       handle (probably "STDOUT") for compatibility with Template.
