title="TEMPLATE TOOLKIT PLUGINS"
-%]<p>
The following plugin modules are distributed with the Template
Toolkit. Some of the plugins interface to external modules (detailed
below) which should be downloaded from any CPAN site and installed
before using the plugin.
</p>
[% WRAPPER subsection
title = "Autoformat"
-%]<p>
The Autoformat plugin is an interface to Damian Conway's Text::Autoformat
Perl module which provides advanced text wrapping and formatting. See
[% ttlink('Template::Plugin::Autoformat') -%] and [% ttlink('Text::Autoformat') -%] for further
details.
</p>
<pre> [% tt_start_tag %] USE autoformat(left=10, right=20) [% tt_end_tag %]
[% tt_start_tag %] autoformat(mytext) [% tt_end_tag %] # call autoformat sub
[% tt_start_tag %] mytext FILTER autoformat [% tt_end_tag %] # or use autoformat filter</pre>
<p>
The Text::Autoformat module is available from CPAN:
</p>
<pre> http://www.cpan.org/modules/by-module/Text/</pre>
[%- END %]
[% WRAPPER subsection
title = "CGI"
-%]<p>
The CGI plugin is a wrapper around Lincoln Stein's
<lstein@genome.wi.mit.edu> CGI.pm module. The plugin is
distributed with the Template Toolkit (see [% ttlink('Template::Plugin::CGI') -%])
and the CGI module itself is distributed with recent versions Perl,
or is available from CPAN.
</p>
<pre> [% tt_start_tag %] USE CGI [% tt_end_tag %]
[% tt_start_tag %] CGI.param('param_name') [% tt_end_tag %]

[% tt_start_tag %] CGI.popup_menu( Name => 'color',
Values => [ 'Green', 'Brown' ] ) [% tt_end_tag %]
[% tt_start_tag %] CGI.end_form [% tt_end_tag %]</pre>
[%- END %]
[% WRAPPER subsection
title = "Datafile"
-%]<p>
Provides an interface to data stored in a plain text file in a simple
delimited format. The first line in the file specifies field names
which should be delimiter by any non-word character sequence.
Subsequent lines define data using the same delimiter as in the first
line. Blank lines and comments (lines starting '#') are ignored. See
[% ttlink('Template::Plugin::Datafile') -%] for further details.
</p>
<p>
/tmp/mydata:
</p>
<pre> # define names for each field
id : email : name : tel
# here's the data
fred : fred@here.com : Fred Smith : 555-1234
bill : bill@here.com : Bill White : 555-5678</pre>
<p>
example:
</p>
<pre> [% tt_start_tag %] USE userlist = datafile('/tmp/mydata') [% tt_end_tag %]</pre>
<pre> [% tt_start_tag %] FOREACH user = userlist [% tt_end_tag %]
[% tt_start_tag %] user.name [% tt_end_tag %] ([% tt_start_tag %] user.id [% tt_end_tag %])
[% tt_start_tag %] END [% tt_end_tag %]</pre>
[%- END %]
[% WRAPPER subsection

strings by delegating to the POSIX strftime() routine. See
[% ttlink('Template::Plugin::Date') -%] and [% ttlink('POSIX') -%] for further details.
</p>
<pre> [% tt_start_tag %] USE date [% tt_end_tag %]
[% tt_start_tag %] date.format [% tt_end_tag %] # current time/date</pre>
<pre> File last modified: [% tt_start_tag %] date.format(template.modtime) [% tt_end_tag %]</pre>
[%- END %]
[% WRAPPER subsection

[%- END %]
[% WRAPPER subsection
title = "DBI"
-%]<p>

<pre> [% tt_start_tag %] USE dumper(indent=0, pad="<br>") [% tt_end_tag %]
[% tt_start_tag %] dumper.dump(myvar, yourvar) [% tt_end_tag %]</pre>
[%- END %]
[% WRAPPER subsection
title = "File"
-%]<p>
The File plugin provides a general abstraction for files and can be
used to fetch information about specific files within a filesystem.
See [% ttlink('Template::Plugin::File') -%] for further details.
</p>
<pre> [% tt_start_tag %] USE File('/tmp/foo.html') [% tt_end_tag %]

to easily create your own modules that define and install new filters.
</p>
<pre> package MyOrg::Template::Plugin::MyFilter;</pre>
<pre> use Template::Plugin::Filter;
use base qw( Template::Plugin::Filter );</pre>
<pre> sub filter {
my ($self, $text) = @_;</pre>

They are now available in a separate Template-GD distribution.
</p>
[%- END %]
[% WRAPPER subsection
title = "HTML"
-%]<p>
The HTML plugin is very basic, implementing a few useful
methods for generating HTML. It is likely to be extended in the future
or integrated with a larger project to generate HTML elements in a generic
way (as discussed recently on the mod_perl mailing list).
</p>
<pre> [% tt_start_tag %] USE HTML [% tt_end_tag %]
[% tt_start_tag %] HTML.escape("if (a < b && c > d) ..." [% tt_end_tag %]
[% tt_start_tag %] HTML.attributes(border => 1, cellpadding => 2) [% tt_end_tag %]
[% tt_start_tag %] HTML.element(table => { border => 1, cellpadding => 2 }) [% tt_end_tag %]</pre>
<p>

</p>
[%- END %]
[% WRAPPER subsection
title = "Iterator"
-%]<p>
The Iterator plugin provides a way to create a Template::Iterator
object to iterate over a data set. An iterator is created
automatically by the FOREACH directive and is aliased to the 'loop'
variable. This plugin allows an iterator to be explicitly created
with a given name, or the default plugin name, 'iterator'. See
[% ttlink('Template::Plugin::Iterator') -%] for further details.
</p>
<pre> [% tt_start_tag %] USE iterator(list, args) [% tt_end_tag %]</pre>
<pre> [% tt_start_tag %] FOREACH item = iterator [% tt_end_tag %]
[% tt_start_tag %] '<ul>' IF iterator.first [% tt_end_tag %]

[%- END %]
[% WRAPPER subsection
title = "Pod"
-%]<p>
This plugin provides an interface to the [% ttlink('Pod::POM', 'Pod::POM') -%] module
which parses POD documents into an internal object model which can
then be traversed and presented through the Template Toolkit.
</p>
<pre> [% tt_start_tag %] USE Pod(podfile) [% tt_end_tag %]</pre>
<pre> [% tt_start_tag %] FOREACH head1 = Pod.head1;
FOREACH head2 = head1/head2;
...
END;
END
[% tt_end_tag %]</pre>
[%- END %]
[% WRAPPER subsection
title = "String"
-%]<p>
The String plugin implements an object-oriented interface for
manipulating strings. See [% ttlink('Template::Plugin::String') -%] for further

[%- END %]
[% WRAPPER subsection
title = "Table"
-%]<p>
The Table plugin allows you to format a list of data items into a
virtual table by specifying a fixed number of rows or columns, with
an optional overlap. See [% ttlink('Template::Plugin::Table') -%] for further
details.
</p>
<pre> [% tt_start_tag %] USE table(list, rows=10, overlap=1) [% tt_end_tag %]</pre>
<pre> [% tt_start_tag %] FOREACH item = table.col(3) [% tt_end_tag %]

[%- END %]
[% WRAPPER subsection
title = "URL"
-%]<p>

part and a variable set of parameters. See [% ttlink('Template::Plugin::URL') -%]
for further details.
</p>
<pre> [% tt_start_tag %] USE mycgi = url('/cgi-bin/bar.pl', debug=1) [% tt_end_tag %]</pre>
<pre> [% tt_start_tag %] mycgi [% tt_end_tag %]
# ==> /cgi/bin/bar.pl?debug=1</pre>
<pre> [% tt_start_tag %] mycgi(mode='submit') [% tt_end_tag %]
# ==> /cgi/bin/bar.pl?mode=submit&debug=1</pre>
[%- END %]
[% WRAPPER subsection
title = "Wrap"
-%]<p>

<muir@idiom.com> (with help from Tim Pierce and many many others)
to provide simple paragraph formatting. See [% ttlink('Template::Plugin::Wrap') -%]
and [% ttlink('Text::Wrap') -%] for further details.
</p>
<pre> [% tt_start_tag %] USE wrap [% tt_end_tag %]
[% tt_start_tag %] wrap(mytext, 40, '* ', ' ') [% tt_end_tag %] # use wrap sub
[% tt_start_tag %] mytext FILTER wrap(40) -[% tt_end_tag %] # or wrap FILTER</pre>

border = 0
cellpadding = 4
cellspacing = 1
}
