plugin provides a simple interface to directory listings. It is derived from the <a href="../../../modules/Template/Plugin/File.html">Template::Plugin::File</a> module and uses <a href="../../../modules/Template/Plugin/File.html">Template::Plugin::File</a> object instances to represent files within a directory. Sub-directories within a directory are represented by further <code>Template::Plugin::Directory</code> instances. </p> <p> The constructor expects a directory name as an argument. </p> <pre><span class="tt">[% USE dir = Directory('/tmp') %]</span></pre> <p> It then provides access to the files and sub-directories contained within the directory. </p> <pre># regular files (not directories) <span class="tt">[% FOREACH file IN dir.files %]</span> <span class="tt">[% file.name %]</span> <span class="tt">[% END %]</span> # directories only <span class="tt">[% FOREACH file IN dir.dirs %]</span> <span class="tt">[% file.name %]</span> <span class="tt">[% END %]</span> # files and/or directories <span class="tt">[% FOREACH file IN dir.list %]</span> <span class="tt">[% file.name %]</span> (<span class="tt">[% file.isdir ? 'directory' : 'file' %]</span>) <span class="tt">[% END %]</span></pre> <p> The plugin constructor will throw a <code>Directory</code> error if the specified path does not exist, is not a directory or fails to <code>stat()</code> (see <a href="../../../modules/Template/Plugin/File.html">Template::Plugin::File</a>). Otherwise, it will scan the directory and create lists named '<code>files</code>' containing files, '<code>dirs</code>' containing directories and '<code>list</code>' containing both files and directories combined. The <code>nostat</code> option can be set to disable all file/directory checks and directory scanning. </p> <p> Each file in the directory will be represented by a <a href="../../../modules/Template/Plugin/File.html">Template::Plugin::File</a> object instance, and each directory by another <code>Template::Plugin::Directory</code>. If the <code>recurse</code> flag is set, then those directories will contain further nested entries, and so on. With the <code>recurse</code> flag unset, as it is by default, then each is just a place marker for the directory and does not contain any further content unless its <code>scan()</code> method is explicitly called. The <code>isdir</code> flag can be tested against files and/or directories, returning true if the item is a directory or false if it is a regular file. </p> <pre><span class="tt">[% FOREACH file = dir.list %]</span> <span class="tt">[% IF file.isdir %]</span> * Directory: <span class="tt">[% file.name %]</span> <span class="tt">[% ELSE %]</span> * File: <span class="tt">[% file.name %]</span> <span class="tt">[% END %]</span> <span class="tt">[% END %]</span></pre> <p> This example shows how you might walk down a directory tree, displaying content as you go. With the recurse flag disabled, as is the default, we need to explicitly call the <code>scan()</code> method on each directory, to force it to lookup files and further sub-directories contained within. </p> <pre><span class="tt">[% USE dir = Directory(dirpath) %]</span> * <span class="tt">[% dir.path %]</span> <span class="tt">[% INCLUDE showdir %]</span> <span class="tt">[% BLOCK showdir -%]</span> <span class="tt">[% FOREACH file = dir.list -%]</span> <span class="tt">[% IF file.isdir -%]</span> * <span class="tt">[% file.name %]</span> <span class="tt">[% file.scan -%]</span> <span class="tt">[% INCLUDE showdir dir=file FILTER indent(4) -%]</span> <span class="tt">[% ELSE -%]</span> - <span class="tt">[% f.name %]</span> <span class="tt">[% END -%]</span> <span class="tt">[% END -%]</span> <span class="tt">[% END %]</span></pre> <p> This example is adapted (with some re-formatting for clarity) from a test in <i>t/directry.t</i> which produces the following output: </p> <pre>* test/dir - file1 - file2 * sub_one - bar - foo * sub_two - waz.html - wiz.html - xyzfile</pre> <p> The <code>recurse</code> flag can be set (disabled by default) to cause the constructor to automatically recurse down into all sub-directories, creating a new <code>Template::Plugin::Directory</code> object for each one and filling it with any further content. In this case there is no need to explicitly call the <code>scan()</code> method. </p> <pre><span class="tt">[% USE dir = Directory(dirpath, recurse=1) %]</span> ... <span class="tt">[% IF file.isdir -%]</span> * <span class="tt">[% file.name %]</span> <span class="tt">[% INCLUDE showdir dir=file FILTER indent(4) -%]</span> <span class="tt">[% ELSE -%]</span> ...</pre> <p> The directory plugin also provides support for views. A view can be defined as a <code>VIEW ... END</code> block and should contain <code>BLOCK</code> definitions for files ('<code>file</code>') and directories ('<code>directory</code>'). </p> <pre><span class="tt">[% VIEW myview %]</span> <span class="tt">[% BLOCK file %]</span> - <span class="tt">[% item.name %]</span> <span class="tt">[% END %]</span> <span class="tt">[% BLOCK directory %]</span> * <span class="tt">[% item.name %]</span> <span class="tt">[% item.content(myview) FILTER indent %]</span> <span class="tt">[% END %]</span> <span class="tt">[% END %]</span></pre> <p> The view <code>print()</code> method can then be called, passing the <code>Directory</code> object as an argument. </p> <pre><span class="tt">[% USE dir = Directory(dirpath, recurse=1) %]</span> <span class="tt">[% myview.print(dir) %]</span></pre> <p> When a directory is presented to a view, either as <code>[% myview.print(dir) %]</code> or <code>[% dir.present(view) %]</code>, then the <code>directory</code> <code>BLOCK</code> within the <code>myview</code> <code>VIEW</code> is processed. The <code>item</code> variable will be set to alias the <code>Directory</code> object. </p> <pre><span class="tt">[% BLOCK directory %]</span> * <span class="tt">[% item.name %]</span> <span class="tt">[% item.content(myview) FILTER indent %]</span> <span class="tt">[% END %]</span></pre> <p> In this example, the directory name is first printed and the content(view) method is then called to present each item within the directory to the view. Further directories will be mapped to the <code>directory</code> block, and files will be mapped to the <code>file</code> block. </p> <p> With the recurse option disabled, as it is by default, the <code>directory</code> block should explicitly call a <code>scan()</code> on each directory. </p> <pre><span class="tt">[% VIEW myview %]</span> <span class="tt">[% BLOCK file %]</span> - <span class="tt">[% item.name %]</span> <span class="tt">[% END %]</span> <span class="tt">[% BLOCK directory %]</span> * <span class="tt">[% item.name %]</span> <span class="tt">[% item.scan %]</span> <span class="tt">[% item.content(myview) FILTER indent %]</span> <span class="tt">[% END %]</span> <span class="tt">[% END %]</span> <span class="tt">[% USE dir = Directory(dirpath) %]</span> <span class="tt">[% myview.print(dir) %]</span></pre> </div> </div> <div class="section"> <div class="head"> <h1 id="AUTHORS" onclick="switch_section(this)" title="Click title to show/hide section content.">AUTHORS</h1> <a href="#body" class="top" title="Back up to the top of the page" >Top</a> </div> <div class="body"> <p> Michael Stevens wrote the original Directory plugin on which this is based.
