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

NAME
Template::Plugin::Dumper - Plugin interface to Data::Dumper SYNOPSIS
[% USE Dumper %] [% Dumper.dump(variable) %] [% Dumper.dump_html(variable) %] DESCRIPTION
This is a very simple Template Toolkit Plugin Interface to the Data::Dumper module. A "Dumper" object will be instantiated via the following directive: [% USE Dumper %] As a standard plugin, you can also specify its name in lower case: [% USE dumper %] The "Data::Dumper" "Pad", "Indent" and "Varname" options are supported as constructor arguments to affect the output generated. See Data::Dumper for further details. [% USE dumper(Indent=0, Pad="<br>") %] These options can also be specified in lower case. [% USE dumper(indent=0, pad="<br>") %] METHODS
There are two methods supported by the "Dumper" object. Each will output into the template the contents of the variables passed to the object method. dump() Generates a raw text dump of the data structure(s) passed [% USE Dumper %] [% Dumper.dump(myvar) %] [% Dumper.dump(myvar, yourvar) %] dump_html() Generates a dump of the data structures, as per dump(), but with the characters <, > and & converted to their equivalent HTML entities and newlines converted to <br>. [% USE Dumper %] [% Dumper.dump_html(myvar) %] AUTHOR
