NAME

Posy::Plugin::DynamicCss - Posy plugin to load different CSS styles based on the UserAgent.

VERSION

This describes version 0.42 of Posy::Plugin::DynamicCss.

SYNOPSIS

    @plugins = qw(Posy::Core
	Posy::Plugin::YamlConfig
	...
	Posy::Plugin::DynamicCss
	...
	));
    @actions = qw(init_params
	    ...
	    head_template
	    dynamic_css_set
	    head_render
	    ...
	);

DESCRIPTION

This plugin enables Posy users to load different CSS stylesheets based on the UserAgent.

There is one variable filled in by this plugin that can be used within your flavour files. The $flow_dynamic_css_line variable contains the stylesheet link metatag for the currently selected (browser-specific) CSS file. This variable must be inserted into your head flavour file.

Activation

This plugin needs to be added to both the plugins list and the actions list. It doesn't really matter where it is in the plugins list, just so long as you also have the Posy::Plugin::YamlConfig plugin as well.

In the actions list, 'dynamic_css_set' needs to go somewhere after head_template and before head_render, since the config needs to have been read, and this needs to set values before the head is rendered.

Configuration

This expects configuration settings in the $self->{config} hash, which, in the default Posy setup, can be defined in the main "config" file in the config directory.

This requires the Posy::Plugin::YamlConfig plugin (or equivalent), because the configuration variables for this plugin are not simple string values; it expects the config values to be in a hash at $self->{config}->{dynamic_css}

dynamic_css

A hash containing the settings.

default

The default CSS link to use when one can't figure out the browser.

files

A hash containing, for each browser, the browser string to compare against, and the CSS link to use if it matches.

Example config file:

---
dynamic_css:
  default: '/styles/layout_netscape.css'
  files:
    gecko: '/styles/layout_gecko.css'
    'MSIE.6|MSIE.5': '/styles/layout_msie.css'
    'Mozilla.4' : '/styles/layout_netscape.css'

Flow Action Methods

Methods implementing actions.

dynamic_css_set

$self->dynamic_css_set($flow_state)

Sets $flow_state->{dynamic_css_line} (aka $flow_dynamic_css_line) to be used inside flavour files.

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::DynamicCss

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
Posy::Plugin::YamlConfig

Test::More
