Template::Plugin::YAML(3pm)				User Contributed Perl Documentation			       Template::Plugin::YAML(3pm)

NAME
Template::Plugin::YAML - Plugin interface to YAML SYNOPSIS
[% USE YAML %] [% YAML.dump(variable) %] [% YAML.dump_html(variable) %] [% value = YAML.undump(yaml_string) %] [% YAML.dumpfile(filename, variable) %] [% value = YAML.undumpfile(filename) %] DESCRIPTION
This is a simple Template Toolkit Plugin Interface to the YAML module. A YAML object will be instantiated via the following directive: [% USE YAML %] As a standard plugin, you can also specify its name in lower case: [% USE yaml %] METHODS
These are the methods supported by the YAML object. dump( @variables ) Generates a raw text dump of the data structure(s) passed [% USE Dumper %] [% yaml.dump(myvar) %] [% yaml.dump(myvar, yourvar) %] dump_html( @variables ) Generates a dump of the data structures, as per "dump", but with the characters <, > and & converted to their equivalent HTML entities, spaces converted to &nbsp; and newlines converted to <br>. [% USE yaml %] [% yaml.dump_html(myvar) %] undump( $string ) Converts a YAML-encoded string into the equivalent data structure. Here's a way to deep-copy a complex structure by completely serializing the data. [% USE yaml; yaml_string = yaml.dump(complex_data_structure); complex_copy = yaml.undump(yaml_string); %] dumpfile( $file, @variables ) Converts the data to YAML encoding, and dumps it to the specified filepath. [% USE yaml; yaml.dumpfile(".storage", my_data) %] undumpfile( $file ) Loads the YAML-encoded data from the specified filepath [% USE yaml; my_data = yaml.undumpfile(".storage") %] AUTHORS
