Programmer HTML Webtree

ProgrammerHTML Webtree 1. Introduction

Webtree is a built-in feature of ProgrammerHTML which allows you to define a logical tree of your site, and the structure-variables will be available within your plugin tags written in Perl.

ProgrammerHTML Webtree 2. How To Use

You can name the file structure which can look like this:

# --- this is a sample webtree-structure file

index.phtml {

cookbook.phtml

plugins.phtml

webtree.phtml {

another-file.phtml

etc.phtml

}

}

Instead to call phtml with files, just call it like

% phtml -webtree structure

Following variables you can use within <def>-tag when you use plugin=inline language=perl.

$child{$p} comma separated sub-links, .phtml or .html as defined in structure-files. $p = 'root' top-most node $parent{$p} comma separated up-links $next{$p} link to next page (if one exists) $prev{$p} link to previous page (if one exists) $title{$p} gives you the html-title of the page, maybe you need to run phtml twice as the first past .html may not exist yet $link{$p} gives the html-link of the .phtml page

Within your def-tags you can use this as example:

...

foreach my $c (split(/,/,$child{'index.phtml'})) {

# --- $c is the xyz.phtml of the top-level

print "<p><a href=\"$link{$c}\">$title{$c}</a>\n";

}

...

If you have no frontpage, but then use $child{'root'} for the first-level nodes of the tree.

With a simple traverse-function (walking through $child{..} recursively) you can walk through the entire tree, and as example, create pull-down menus as this site uses on the left-side.
