template::plugin::dumper
Template::Plugin::Dumper(3) User Contributed Perl Documentation Template::Plugin::Dumper(3)
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) %]
