---+!! 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.

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)

  • Image, URL and alternate tooltip text of web's logo.
    • Set WEBLOGOIMG = ""
    • Set WEBLOGOURL = ""
    • Set WEBLOGOALT = " "

  • 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 = off
    • Set SITEMAPWHAT = Educating lawyers using freedom
    • Set SITEMAPUSETO = do something.

  • Copyright notice:
    • Set WEBCOPYRIGHT = This site is powered by the TWiki collaboration platformCopyright © by the contributing authors. All material on this collaboration platform is the property of the contributing authors.

      Note: Please contribute updates to this topic on at TWiki:TWiki.TWikiPreferences

  • 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.
  • 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.

  • 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{}% :

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 = $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
    • Enable content checks before editing
    • Disable WYSIWYG on pages that contain complex TML. On pages that have complex TML, WYSIWYG will fall back to the default text editor.
    • Set WYSIWYG_EXCLUDE = calls

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

  • Vertical size of text edit box: (can be overwritten by user preferences)
    • Set EDITBOXHEIGHT = 22

  • Style of text edit box. Set to width: 99% for full window width (default; this will overwrite the EDITBOXWIDTH setting), or width: auto to disable. This setting works for IE and some other recent browsers. (can be overwritten by user preferences)
    • Set EDITBOXSTYLE = width: 99%

  • Default state of the Force New Revision (ForceNewRevision) check box in preview. Check box is initially checked if Set FORCENEWREVISIONCHECKBOX = checked="checked", or unchecked if empty: (can be overwritten by user preferences)

  • Default state of the Minor Changes, Don't Notify (DontNotify) check box in preview. Check box is initially checked if Set DONTNOTIFYCHECKBOX = checked="checked", or unchecked if empty: (can be overwritten by user preferences)

  • 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)

  • Format of file link when the link check box is checked: (can be overwritten by user preferences)
    • HELP NOTE: Keyword $name gets expanded to filename; $comment to comment; \t to tab (3 spaces for bullets).
      * Set ATTACHEDFILELINKFORMAT = \n   * [[%ATTACHURL%/$name][$name]]: $comment

  • Format of images when the link check box is checked: (can be overwritten by user preferences)
    • HELP NOTE: Keyword $name gets expanded to filename; $comment to comment; $size to width="..." height="..." attribute of img tag; \t to tab and \n to linefeed (3 spaces for bullets).
      * Set ATTACHEDIMAGEFORMAT = \n   * $comment: <br />\n     <img src="%ATTACHURLPATH%/$name" alt="$name" $size />

Access Control Settings

  • Users or groups allowed to change or rename this TWikiPreferences topic:
  • By default, only admins can create webs in the root

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):
  • 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.
