TWiki Site-Level Preferences

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

ALERT! Note: This topic should be regarded as read-only, so that upgrades can safely overwrite it without risk to your customizations.

Preference settings local to your site should be set in Main.TWikiPreferences (this topic is pointed to by {LocalSitePreferences}, which is set by the admin in the configure interface). Settings in Main.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

ALERT! 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)

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

    • Set WEBLOGOIMG = T-logo-140x40-t.gif
    • Set WEBLOGOURL = http://TWiki.org/
    • Set WEBLOGOALT = Powered by TWiki

  • 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.
    • Set SITEMAPUSETO = ...to do something.

  • 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 =

  • 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

Default User Settings

ALERT! NOTE: They are typically redefined in topics of individual TWikiUsers

  • Show tool-tip topic info on mouse-over of WikiWord links. Setting can be on, off, or customized. An empty setting or off setting disables the tool-tips (for better performance). The setting can contain $summary to show the topic summary, $date for the last change date, $rev for the revision, $username for the login name of the last editor, $wikiname for the WikiName, $wikiusername for Main.WikiName, $topic for the topic name, and $web for the web name
    • Set LINKTOOLTIPINFO = off
    • #Set LINKTOOLTIPINFO = $username - $date - $rev: $summary

  • Some skins have two editors available; the default editor, and a second editor which is usually a WYSIWYG editor (the second editor is used by hitting the WYSIWYG link in pattern or classic skins). If COMPOSER is not set, the second editor will work the same as the default editor. If the WysiwygPlugin is installed and it is set to 'kupu' (the default), then the Kupu WYSIWYG editor will be enabled. You can change the setting to use any editor that is enabled by setting the cover parameter on the edit URL.
    • Set COMPOSER = kupu

  • Horizontal size of text edit box: (can be overwritten by user preferences)
    • Set EDITBOXWIDTH = 70

    • Set EDITBOXSTYLE = width: 99%

  • Default state of the link check box in the attach file page. Checkbox is initially checked if Set ATTACHLINKBOX = checked="checked", or unchecked if empty (Set ATTACHLINKBOX =). If checked, a link is created to the attached file at the end of the topic: (can be overwritten by user preferences)
    • Set ATTACHLINKBOX =

Access Control Settings

  • Users or groups allowed to change or rename this TWikiPreferences topic:

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 .

  • ALERT! 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.
  • ALERT! 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 Main.TWikiPreferences.
