Plugin Alphaindex

alphaindex plugin by Hubert Molière
Allows you to insert the alphabetical index of a namespace in a page

Last updated on 2008-10-28. Provides Syntax.
No compatibility info given!

Similar to indexmenu, indexmenu2.

Tagged with index, list, tree.

Description

This simple plugin allows you to insert an alphabetical index of a specified namespace in your pages. It should be useful in Dokuwiki sites where pages are organized by namespaces.

It is fully inspired and based on the indexmenu plugin by Samuele Tognini samuele@netsons.org.

Notes

Syntax

{{alphaindex>[namespace][#n][|nons]}}
[namespace] Namespace name from which the index starts. optional with [n] or nons; “.” is the current namespace; “..” or an empty value shows the top level namespace.
[n] Number that specifies the max level of the tree index nodes. optional; it can be used together with nons.
nons Exclude namespaces nodes from index. It shows only the pages optional.

Example that displays only pages inside wiki:plugins and lower namespaces (max two levels):

{{alphaindex>wiki:plugins#2|nons}}

Css Style

All the data displayed by the alphaindex plugin are inside a div (called “alphaindex”).

You can customize each part of the generated code.

For example if you have defined the begin_letter_tpl as this :

==== {{letter}} ====

the plugin will generate the following html code :

<h3><a name="a" id="a">{{letter}}</a></h3>

and you can create the following css rule (for example) :

#alphaindex h3{
    display: block;
    background-color: #dee7ec;
    padding: 2px 0 2px 10px;
    margin: 20px 0 5px 0;
  }

Configuration

:!: The updated version in the how_to_install section is fully configurable with the config manager.

Optional config option in conf/local.protected.php:

$conf['plugin']['alphaindex']['numerical_index']   = '0-9';
$conf['plugin']['alphaindex']['articles_deletion'] = '^the +|^a +|^an +';
$conf['plugin']['alphaindex']['articles_moving']   = 1;
$conf['plugin']['alphaindex']['empty_msg']         = 'No pages';
$conf['plugin']['alphaindex']['title_tpl']         = '===== Alphabetical index =====';
$conf['plugin']['alphaindex']['begin_letter_tpl']  = '**{{letter}}**';
$conf['plugin']['alphaindex']['entry_tpl']         = '  * [[{{link}}|{{name}}]]';
$conf['plugin']['alphaindex']['end_letter_tpl']    = '';
$conf['plugin']['alphaindex']['hidepages']         = 'start|sidebar';

numerical_index

Text display in block letter title for the page title beginning with a numerical value.

Optional
Default : '0-9'
Example : 'Numerical'

articles_deletion

List of article treated by the plugin. Each article is separated with a '|'.

Optional
Default : (empty)
Example : ^the +|^a +|^an + or ^le +|^la +|^les +|^l\' * (in french)

With the example above, the page 'The Rolling Stones' will be treated as 'Rolling Stones' instead of its real name.

articles_moving

Management of the articles when the article_deletion option is active.

Optional
Default : 1
Authorized values :

Example: with the pagename 'The Rolling Stones'

empty_msg

Message shown in your page when the index is empty.
Note : {{ns}} is an alias for the requested namespace.

Optionnal
Default : 'No index for <b>{{ns}}</b>'

title_tpl

Template (in dokuwiki syntax) for the index title.

Optionnal
Default : '===== Index ====='

begin_letter_tpl

Template (in dokuwiki syntax) at the beginning of each letter's blok.

Note : the {{letter}} pattern is mandatory. It's an alias for the current letter.

Optionnal
Default : '==== {{letter}} ===='

entry_tpl

Template (in dokuwiki syntax) for each letter's entry.
Note : the {{link}} and {{name}} patterns are mandatory.They are aliases for the page link and the page name.

Optionnal
Default : ' * [[{{link}}|{{name}}]]'

end_letter_tpl

Template (in dokuwiki syntax) at the end of each letter's block.

Optionnal
Default : (empty)

hidepages

Name of pages not displayed in the index. Each page name is separated with a '|'.

Optionnal
Default : (empty)
Example : 'start|sidebar'

How to install

:!: There is also a zip updated version with patches by community users.

Download the zip file (3k) and unpack it into lib/plugins folder or use the plugin_manager.

Manually install

Create the folder alphaindex in dokuwiki /lib/plugins directory. Then create the file syntax.php in this folder 1) and paste in it this code:

Todo

* To use the UTF8 functions instead of classic php ones for characters and strings management.

* What's about an update to do Configuration via the Admin-panel?

* And what's about a RegEx for hidepages?

       $match = substr($match,12,-2);

of alphaindex/syntax.php should be:

       $match = substr($match,13,-2);

Jonesy, have fun !

Since it seems that this plugin is abandoned by the original author, i've build an alphaindex darcs containing your patches (i had to manually correct some hunks) . You can fetch it with:
darcs get http://samuele.netsons.org/darcs/alphaindex
I'll apply there any new working patch pubblished here, sended with the darcs mechanism or created by me.
Next step could be to implement a better cache mechanism according for example to the indexmenu action plugin.
It's also possible to install it via plugin manager using this link.
This version only has 1 error. When activate the articles_moving when the article_deletion option is active, look at this example:
$conf['articles_deletion'] = '^the +|^a +|^an +'
$conf['articles_moving']   = 1
$conf['metadata_title']    = 1

If I have a page wich header is 'The Rolling Stones', this page will be treated as 'Rolling Stones' instead of its real name. But the page remains in the letter “T”, and not in the letter “R”.

I see in the code and I found 2 minimal errors:
Line 221

if($this->getConf('metadata_title')
