Insights Collaboration TWiki Site-Level Preferences

This topic defines site-level settings that apply to all users and webs on this TWikiSite.

NOTE: Don't edit this topic, changes will be lost on the next TWiki upgrade. Define new site-level settings, or overload below settings in Public.TWikiPreferences

Preference settings local to your site should be set in Public.TWikiPreferences (this topic is pointed to by {LocalSitePreferences}, which is set by the admin in the configure interface). Settings in Public.TWikiPreferences will override settings in this topic, and should be used for defining custom settings and variables.

Read more on how to set Preferences Variables.

Default Web Preferences

NOTE: These are just defaults; don't change them here. Instead, add them to the WebPreferences topic in each web

List of selected topics in a web (used in menus)
- Set WEBTOPICLIST = Changes | Index | Search | Go

Web-specific background color: (is overwritten by web preferences)
- Set WEBBGCOLOR = #FFD8AA

favicon: Attach a favicon.ico to a web's WebPreferences or add a FAVICON setting to WebPreferences
- Set FAVICON = /twiki/pub/TWiki/WebPreferences/favicon.ico

Image, URL and alternate tooltip text of web's logo.
- Set WEBLOGOIMG =
- Set WEBLOGOURL = http://insights-twiki.pp.rhul.ac.uk/twiki/bin/view/Public/WebHome
- Set WEBLOGOALT = Home - this site is powered by TWiki(R)

List this web in the SiteMap:
- If yes, set SITEMAPLIST to on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Make sure to list only links that include the name of the web, e.g. TWiki.Topic links.
- Set SITEMAPLIST = on
- Set SITEMAPWHAT = Describe what this web does

Copyright notice:
- Set WEBCOPYRIGHT = Copyright © 2008-2024 by the contributing authors. All material on this collaboration platform is the property of the contributing authors.
  Ideas, requests, problems regarding Insights Collaboration TWiki? Send feedback

Simplified Copyright notice for the WebRss feed (don't use any special characters, html tags, entities, wiki markup or WikiWords)
- Set WEBRSSCOPYRIGHT = Copyright 2024 by contributing authors

Exclude web from a web="all" search: (Set to on for hidden webs; is overwritten by web preferences) Note it is much better to use TWikiAccessControls in individual webs to control who can and can't view the contents of a web. NOSEARCHALL is retained for compatibility, but you should avoid using it.
- Set NOSEARCHALL =

Prevent automatic linking of WikiWords and acronyms (if set to on); link WikiWords (if empty); can be overwritten by web preferences:
- Set NOAUTOLINK =
- Note: Use the [[...][...]] syntax to link topics in case you disabled WikiWord linking. The <noautolink> ... </noautolink> syntax can be used to prevents links within a block of text.

Use topic title instead of topic name in forced links, such as in link [[BugItem1234]]. If enabled, the link label is set to the form field named "Title", the topic preferences setting named TITLE, or the topic name if neither exists. Forced links with label such as [[BugItem1234][bug 1234]] are not affected. The topic title can be shown even with disabled flag by using syntax [[+BugItem1234]]. NOTE: Page rendering may be slower if enabled and if there are many forced links in a topic.
- Set SHOWTOPICTITLELINK =

If you use non WikiWords for topic names (for example "Expenses" or "Mighty1") and if you use bracket notation to link to those topics, it is useful to turn of all warnings (like: "WARNING: This topic name is not recommended because it will not be linked automatically") and checkboxes ("Allow non WikiWord for the new topic name"). Can be overwritten by web preferences. Set to on to activate:
- Set HIDE_NON_WIKI_WORD_WARNINGS =

Warn if %INCLUDE{}% of topic fails: Fail silently if empty or off. Output warning message (defined in templates/oopsalerts.tmpl) if set to on. Otherwise output specific text (use $topic for topic). You can override this in web preferences, or by using a warn="..." parameter with %INCLUDE{}% :
- Set INCLUDEWARNING = on

  - Set TOC_MIN_DEPTH =
    - If not set: 1
    - Possible values: 1 to 6
- The last header level to appear in the TOC:
  - Set TOC_MAX_DEPTH =
    - If not set: 6
    - Possible values: 1 to 6

Miscellaneous Settings

Format of a NewWikiWord link:
Note that $text is the topic link text, $summary is the HTML-cleaned topic link text, $topic is the name of the new topic, and $web is the name of the web for the new topic. Values are taken from the link syntax [[$web.$topic][$text]]. For normal plain WikiWord links $text and $topic are the same. The value of $web is the current web unless the link is in the format $web.$topic.
- default setting:
  - Set NEWLINKFORMAT = $text

User signature format. The SIGNATUREFORMAT is used when creating new topics, BUBBLESIGNATUREFORMAT is used when adding comments with CommentPlugin:
- default setting:
  - Set BUBBLESIGNATUREFORMAT = -- %CALCULATE{%B}%UBBLESIG{TWikiGuest - 15 Nov 2024}%
  - Set SIGNATUREFORMAT = -- %CALCULATE{%U}%SERSIG{TWikiGuest - 15 Nov 2024}%
  - Note: The USERSIG is defined in section "user_sig" of UserReports. The desired expanded signature format in a topic is %USERSIG{%WIKINAME% - %DATE%}%, this with unexpanded USERSIG, but expanded WIKINAME and DATE. A hack using CALCULATE is used to keep USERSIG unexpanded: %CALCULATE{%U}%SERSIG{...}%
- alternative legacy setting:
  - #Set SIGNATUREFORMAT = -- TWikiGuest - 15 Nov 2024

Creating New Preference Variables

You can introduce new VARIABLES and use them in your topics and templates. There is no need to change the TWiki engine (Perl scripts).

A preference is defined in a TWikiShorthand bullet item: [3 spaces] * [space] Set NAME = value
Example (as a nested bullet item, indented 6 spaces):
- Set WEBBGCOLOR = #FFFFC0
Preferences are used as TWikiVariables by enclosing the name in percent signs: %. Example:
- When you write variable %WEBBGCOLOR%, it gets expanded to #FFD8AA .

The sequential order of the preference settings is significant. Define preferences that use other preferences FIRST. For example, set WEBCOPYRIGHT before WIKIWEBMASTER since the copyright notice uses the TWiki administrator e-mail address.
In order to protect your custom variables from being overwritten when upgrading the TWiki.TWikiPreferences topic, it is recommended that custom variables are defined in Public.TWikiPreferences.

Protected System Settings

The following settings are declared final to protect them as read only. These are system variables that should never be attempted set or altered in any preference topic or topic settings.

Set FINALPREFERENCES = WEB, TOPIC

This topic should not be edited.
