The Natural Skin

Description

NatSkin is a skin driven by cascading stylesheets which is shipped with 12 predefined styles and 10 style variations that can be applied to each. Most of these are inspired by the MovableType and WordPress among others a port of the Kubrick style by Michael Heilemann and thus can provide a blog-like layout. This includes a PatternSkin style that emulates the look&feel of the PatternSkin as it is known from the TWiki/Cairo release.

Features

• Skin state: an internal representation of different ways to render the NatSkin concerning
  • the skin style,
  • style variants,
  • the sidebar location,
  • the page border decoration,
  • the web buttons in the topbar and
  • the positioning of the search box
• Conditional content:
  • USERACTIONS, NATLOGON: display topic actions depending on the user being logged in or not
  • IFSKINSTATE: render skin differently depending on the current skin state
  • IFACCESS: render different content or include topics depending on access rights
• skin style control: infrastructure to get, set and display the skin style that is currently active using the NatSkinStyleBrowser
• WebSideBar: a configurable navigation bar
• MySideBar^?: every user can extend the sidebar with a personalized navigation
• NatSearch: a search+go box that combines advanced search with the GO feature of twiki
• Login page: independent implementation of a login page for maximal compatibility with old TWiki releases; this is similar to the TemplateLogin authentication mechanism in Dakar but only provides htpasswd based authentication
• email address obfuscation: all email addresses in topic texts are obfuscated by the use of dynamic html; so mailto links are still clickable while the pure html text does not allow to extract the addresses by respective web crawlers.
• marking external links: add a nice icon to offsite links

NatSearch

This is a cgi-script that is heavily based on the PhotonSearch of the TWiki:Plugins/PhotonSkin. So natsearch is basically a fork of that including fixes to similar security flaws that hit the WebSearch those days also.

NatSearch can be further reduced to certain webs and topics by setting WebPreferences. Besides the NOSEARCHALL feature of every web that excludes a web from search the following variables restrict the hit set:

Name	Description
NATSEARCHINCLUDEWEB	a regular expression that must match webs to be considered
NATSEARCHEXCLUDEWEB	a regular expression that must not match a web
NATSEARCHINCLUDETOPIC	a regular expression that must match a topic in the hit set
NATSEARCHEXCLUDETOPIC	a regular expression that excludes a topic from the hit set

Furthermore, the variable NATSEARCHTEMPLATE can be set to a template topic that is used instead of the skin's search template. This can be used in TWikiApplications to define a customized look of search results.

Please see the TWiki:Plugins/PhotonSkin for an explanation of the possible search parameters (TODO: maby move that stuff in here).

About the WebSideBar^?

The WebSideBar^? is used to generate a navigation appearing next to the main topic area. Each web in your FS might optionaly have a separate WebSideBar^?. The default TWiki.WebSideBar^? can be used to add a default section common to all WebSideBars^?. If the WebSideBar^? isn't defined the default TWiki.WebSideBar^? is used. Each user might define a personalized WebSideBar^? called %WIKINAME%SideBar that is appended to the WebSideBar^?. The TWiki:Plugins/RedDotPlugin is used to make customizing the WebSideBar^? easier appended to the different parts that make up the complete sidebar. These are hidden if you don't have write access to the respective topic fragments.

About the WebButtons^?

The WebButtons^? are used to render the button toolbar at the top of the page when the STYLEBUTTONS setting is set to "on". The WebButtons^? are an unordered list of those links that should be visible there. There exists one WebButtons^? topic by default in the TWiki web. You can define a WebButtons^? topic per web overwriting the settings in the TWiki.WebButtons topic. If you do not define a WebButtons^? topic in a web then the default one will be used displaying a set of links to all public webs in your FS installation.

About Logon & Logout

LOGONTOPIC

The layout of the NatSkin can be configured online using the NatSkinStyleBrowser

• by selecting one of the predefined styles;
• by selectiong one of the predefined variations;
• the sidebar can be displayed on the left or right;
• the page border can be toggled on and off;
• there are so-called WebButtons^? that can be switched on and off displaying webs as tabs;
• the position of the search box can be set to one of four predefined positions.

The result can be configured per session, user, web or for the complete site. The screenshots below only display a limitted set of all possible combinations.

This skin includes an enhanced navigation mechanism named WebSideBar^?. This combines the best of the old WebMenu idea from the GnuSkin and the WebLeftBar known from the TWiki:Plugins/PatternSkin by providing all the flexibility of the WebLeftBar including the MySideBar^? feature and an enhanced navigation scheme.

This is a rework of the TWiki:Plugins/CopyCatSkin by TWiki:Main/MattWilkie. It is used at the Natural Language Systems Division (NATS) of the University of Hamburg, Germany.

Selecting Styles

You can try alternative styles

1. per request: by appending style=<skin-name> to the end of the url; alternatively, use the NatSkinStyleBrowser
2. per user by setting a variable SKINSYLE on your TWikiGuest homepage
3. per web by setting the variable SKINSTYLE in the WebPreferences
4. site-wide by setting the skinstyle in the TWikiPreferences

See the NatSkinPlugin^? for more information on how to predefine the variants of NatSkin. The default style is hardcoded into the NatSkinPlugin^?.
