The Natural Skin

Description

Nat Skin 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 Pattern Skin style that emulates the look&feel of the Pattern Skin as it is known from the TWiki/Cairo release.

The layout of the Nat Skin can be configured online using the Nat Skin Style Browser

• by selecting one of the predefined styles;
• by selectiong one of the predefined variations;
• the sidebar can be displayed left or right or both for a 3 columns layout;
• the page border can be switched on, off or enable a thin blog-like layout;
• there are so-called Web Buttons^? displaying webs as tabs that can be switched on and off;
• the position of the search box can be set to one of four predefined positions.

The screenshots below only display a limited set of all possible combinations.

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.

Features

• Skin state: an internal representation of different ways to render the Nat Skin 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
• skin style control: infrastructure to get, set and display the skin style that is currently active using the Nat Skin Style Browser
• 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
• WebSideBar: a configurable navigation bar
• My Side Bar: 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

NatSearch unifies the Seach and the Jump box known from the standard TWiki. You can use one input field to either jump to a topic or start a content query.

NatSearch is heavily inspired by the PhotonSearch of the TWiki:Plugins/PhotonSkin.

Usage

This basically works in three modes:

1. GO: go to the named topic
2. topic search: search a topic whose name matches the search string
3. content search: search a topic whose content matches the search string

NatSearch proceeds along the following lines:

1. the search string starts with an uppercase letter:
   1. try a GO
   2. fallback to a topic search when 1.1 fails
   3. fallback to content search when 1.2 fails
2. the string starts with a /:
   normal content search
3. the string does not start with an upper case letter or /
   1. try a topic search
   2. fallback to content search

If only one topic was found then NatSearch jumps to that topic directly.

Options

The search string may be prepended with a set of options that are separated from the rest of the search string with a colon(:). Known options are:

Option	Description
g	global search (default is local)
l	local search
u	case-sensitive search (default is to ignore case)

A search string may consist of a list of terms that are retrieved. If a term shall contain spaces it can be surrounded by double quotes. Each term may be preceded with a minus (-) to exclude this term from the hit set.

Examples

Search	Description
TWikiUsers	if the current web is the Main go to the TWikiUsers
	if the current web is the TWiki go to the TWikiUsersGuide
g:twikiusers	list all topics in all webs whose name match "twikiusers"
/TWikiUsers	list all topics that contain the word "TWikiUsers"
gu:copyright	list all topics that contain the word "copyright" in lowercase
g:copyright -webpref	list all topics that contain the word "copyright" but not "webpref"
g:"Good morning" -natskin	list all topics that contain the term "Good morning" but not "natskin"

Customization

NatSearch can be restricted to certain webs and topics by setting Web Preferences. 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 Web Preferences 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.

Special topic variables

There is a set of variables that can be used in a topic to influence the Nat Skin.

Name	Description
PAGETITLE	the <title>... of the html page; if no PAGETITLE is defined the Nat Skin will check for some formfields (Headlines, TopicDescription) to be used as a html page title and back off to the topic name
KEYWORDS	the value of this variable will be used to construct <meta name="keywords" ... /> in the html head; in addition SubjectCategory, BlogTag and Tags formfields will be used to generate keywords
WHITEBOARD	possible values: on, off; if WHITEBOARD is set to only the topic form will be edited when clicking on "Edit"; note, that the textarea is still accessible and not hidden completely; this is flag is only there for convenience
