NAME

Template::Mustache - Drawing Mustaches on Perl for fun and profit

VERSION

version 0.5.6

SYNOPSIS

    use Template::Mustache;

    print Template::Mustache->render(
        "Hello {{planet}}", {planet => "World!"}), "\n";

DESCRIPTION

Template::Mustache is an implementation of the fabulous Mustache templating language for Perl 5.8 and later.

See http://mustache.github.com.

Functions

build_pattern($otag, $ctag)

Constructs a new regular expression, to be used in the parsing of Mustache templates.

$otag

The tag opening delimiter.

$ctag

The tag closing delimiter.

Returns a regular expression that will match tags with the specified delimiters.

read_file($filename)

Reads a file into a string, returning the empty string if the file does not exist.

$filename

The name of the file to read.

Returns the contents of the given filename, or the empty string.

parse($tmpl, [$delims, [$section, $start]])

Can be called in one of three forms:

parse($tmpl)

Creates an AST from the given template.

$tmpl

The template to parse.

An array reference to the AST represented by the given template.

parse($tmpl, $delims)

Creates an AST from the given template, with non-standard delimiters.

$tmpl

The template to parse.

$delims

An array reference to the delimiter pair with which to begin parsing.

Returns an array reference to the AST represented by the given template.

parse($tmpl, $delims, $section, $start)

Parses out a section tag from the given template.

$tmpl

The template to parse.

$delims

An array reference to the delimiter pair with which to begin parsing.

$section

The name of the section we're parsing.

$start

The index of the first character of the section.

Returns an array reference to the raw text of the section (first element), and the index of the character immediately following the close section tag (last element).

generate($parse_tree, $partials, @context)

Produces an expanded version of the template represented by the given parse tree.

$parse_tree

The AST of a Mustache template.

$partials

A subroutine that looks up partials by name.

@context

The context stack to perform key lookups against.

Returns the fully rendered template as a string.

lookup($field, @context)

Performs a lookup of a $field in a context stack.

$field

The field to look up.

@context

The context stack.

Returns the context element and value for the given $field.

Methods

new(%args)

Standard hash constructor.

%args

Initialization data.

Returns A new Template::Mustache instance.

template_path

Filesystem path for template and partial lookups.

Returns a string containing the template path (defaults to '.').

template_extension

File extension for templates and partials.

Returns the file extension as a string (defaults to 'mustache').

template_namespace

Package namespace to ignore during template lookups.

As an example, if you subclass Template::Mustache as the class My::Heavily::Namepaced::Views::SomeView, calls to render will automatically try to load the template ./My/Heavily/Namespaced/Views/SomeView.mustache under the template_path. Since views will very frequently all live in a common namespace, you can override this method in your subclass, and save yourself some headaches.

   Setting template_namespace to:      yields template name:
     My::Heavily::Namespaced::Views => SomeView.mustache
     My::Heavily::Namespaced        => Views/SomeView.mustache
     Heavily::Namespaced            => My/Heavily/Namespaced/Views/SomeView.mustache

As noted by the last example, namespaces will only be removed from the beginning of the package name.

Returns the empty string.

template_file

The template filename to read. The filename follows standard Perl module lookup practices (e.g. My::Module becomes My/Module.pm) with the following differences:

  • Templates have the extension given by template_extension ('mustache' by default).

  • Templates will have template_namespace removed, if it appears at the beginning of the package name.

  • Template filename resolution will short circuit if $Template::Mustache::template_file is set.

  • Template filename resolution may be overriden in subclasses.

  • Template files will be resolved against template_path, not $PERL5LIB.

Returns The path to the template file, relative to template_path as a string. See template.

template

Reads the template off disk.

Returns the contents of the template_file under template_path.

partial($name)

Reads a named partial off disk.

$name

The name of the partial to lookup.

Returns the contents of the partial (in template_path of type template_extension), or the empty string, if the partial does not exist.

render

Render a class or instances data, in each case returning the fully rendered template as a string; can be called in one of the following forms:

render()

Renders a class or instance's template with data from the receiver. The template will be retrieved by calling the template method. Partials will be fetched by partial.

render($tmpl)

Renders the given template with data from the receiver. Partials will be fetched by partial.

$tmpl

The template to render.

render($data)

Renders a class or instance's template with data from the receiver. The template will be retrieved by calling the template method. Partials will be fetched by partial.

$data

Data (as hash or object) to be interpolated into the template.

render($tmpl, $data)

Renders the given template with the given data. Partials will be fetched by partial.

$tmpl

The template to render.

$data

Data (as a hash, class, or object) to be interpolated into the template.

render($tmpl, $data, $partials)

Renders the given template with the given data. Partials will be looked up by calling the given code reference with the partial's name.

$tmpl

The template to render.

$data

Data (as a hash, class, or object) to be interpolated into the template.

$partials

A function used to lookup partials.

render($tmpl, $data, $partials)

Renders the given template with the given data. Partials will be looked up by calling the partial's name as a method on the given class or object.

$tmpl

The template to render.

$data

Data (as a hash, class, or object) to be interpolated into the template.

$partials

A thing (class or object) that responds to partial names.

render($tmpl, $data, $partials)

Renders the given template with the given data. Partials will be looked up in the given hash.

$tmpl

The template to render.

$data

Data (as a hash, class, or object) to be interpolated into the template.

$partials

A hash containing partials.
