NAME

Posy::Plugin::EntryTitles - Posy plugin to cache entry titles.

VERSION

This describes version 0.51 of Posy::Plugin::EntryTitles.

SYNOPSIS

    @plugins = qw(Posy::Core
		  Posy::Plugin::EntryTitles
		  ...
		  ));
    @actions = qw(
	....
	index_entries
	index_titles
	...
	);

DESCRIPTION

This is a "utility" plugin to be used by other plugins; it maintains a list (and cache) of entry titles in $self->{titles} which can be used by other plugins (such as Posy::Plugin::NearLinks).

It provides an action method "index_titles" which should be put after "index_entries" in the action list.

This plugin is useful not only for efficiency reasons, but it means that other plugins don't have to know how to extract the title from a given format of file; the title for a HTML file, for example, is not parsed in the same way as that for a plain text file. Those who wish to introduce additional formats need only override the "get_title" method and everything will work just as smoothly. Ah, inheritance, I love it.

Configuration

The following config values can be set:

titles_cachefile

The full name of the file to be used to store the cache. Most people can just leave this at the default.

Parameters

This plugin will do reindexing the first time it is run, or if it detects that there are files in the main file index which are new. Full or partial reindexing can be forced by setting the the following parameters:

reindex_all
/cgi-bin/posy.cgi?reindex_all=1

Does a full reindex of all files in the data_dir directory, clearing the existing information and starting again.

reindex
/cgi-bin/posy.cgi?reindex=1

Updates information for new files only.

reindex_cat
/cgi-bin/posy.cgi?reindex_cat=stories/buffy

Does an additive reindex of all files under the given category. Does not delete files from the index. Useful to call when you know you've just updated/added files in a particular category index, and don't want to have to reindex the whole site.

delindex
/cgi-bin/posy.cgi?delindex=1

Deletes files from the index if they no longer exist. Useful when you've deleted files but don't want to have to reindex the whole site.

OBJECT METHODS

Documentation for developers and those wishing to write plugins.

init

Do some initialization; make sure that default config values are set.

Flow Action Methods

Methods implementing actions.

index_titles

Find the titles of the entry files. This uses caching by default.

Expects $self->{config} and $self->{files} to be set.

Helper Methods

Methods which can be called from elsewhere.

get_title

$title = $self->get_title($file_id);

Get the title of the given entry file (by reading the file). (If you are introducing a new file-type, you should override this)

Private Methods

Methods which may or may not be here in future.

_et_init_caching

Initialize the caching stuff used by index_entries

_et_read_cache

Reads the cached information used by index_entries

_et_save_cache

Saved the information gathered by index_entries to caches.

INSTALLATION

Installation needs will vary depending on the particular setup a person has.

Administrator, Automatic

If you are the administrator of the system, then the dead simple method of installing the modules is to use the CPAN or CPANPLUS system.

cpanp -i Posy::Plugin::EntryTitles

This will install this plugin in the usual places where modules get installed when one is using CPAN(PLUS).

Administrator, By Hand

If you are the administrator of the system, but don't wish to use the CPAN(PLUS) method, then this is for you. Take the *.tar.gz file and untar it in a suitable directory.

To install this module, run the following commands:

perl Build.PL
./Build
./Build test
./Build install

Or, if you're on a platform (like DOS or Windows) that doesn't like the "./" notation, you can do this:

perl Build.PL
perl Build
perl Build test
perl Build install

User With Shell Access

If you are a user on a system, and don't have root/administrator access, you need to install Posy somewhere other than the default place (since you don't have access to it). However, if you have shell access to the system, then you can install it in your home directory.

Say your home directory is "/home/fred", and you want to install the modules into a subdirectory called "perl".

Download the *.tar.gz file and untar it in a suitable directory.

perl Build.PL --install_base /home/fred/perl
./Build
./Build test
./Build install

This will install the files underneath /home/fred/perl.

You will then need to make sure that you alter the PERL5LIB variable to find the modules, and the PATH variable to find the scripts (posy_one, posy_static).

Therefore you will need to change: your path, to include /home/fred/perl/script (where the script will be)

PATH=/home/fred/perl/script:${PATH}

the PERL5LIB variable to add /home/fred/perl/lib

PERL5LIB=/home/fred/perl/lib:${PERL5LIB}

REQUIRES

Posy
Posy::Core

Test::More
