Техническая поддержка Site-Level Preferences

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

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.SitePreferences (this topic is pointed to by {LocalSitePreferences}, which is set by the admin in the configure interface). Settings in Main.SitePreferences will override settings in this topic, and should be used for defining custom settings.

Read more on how to set preferences.

Default Web Preferences

    • Set WEBLOGOURL = /Main/WebHome
    • Set WEBLOGOALT = Powered by Foswiki, The Free and Open Source Wiki

  • 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. System.Topic links.
    • Set SITEMAPLIST = on

    • 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 AccessControls 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{}% :

  • Generated Table of Contents (TOC) settings
    • The first header level to appear in the TOC:
      • Set TOC_MIN_DEPTH =

        • If not set: 6
        • Possible values: 1 to 6
        • Can be overridden by depth parameter of TOC

        • If not set: included TOC is shown
        • Possible values: on or nothing

Default User Settings

ALERT! NOTE: They are typically redefined in the individual users topic. eg. WikiGuest.

  • 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 - $date - r$rev: $summary
      • This is exactly equivalent to:

Deprecated editor settings

These settings are overridden by an editor cookie that is set when using the Sizing and font buttons on the lower right corner of the edit window. These settings will be ignored once a FOSWIKIPREF cooke has been set. They have been removed from Foswiki 2.0.

  • Default state of the Minor Changes, Don't Notify 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 $filename gets expanded to filename; $fileurl gets expanded to the urlencoded filename; $comment to comment; \t to tab (3 spaces for bullets).

E-mail Settings

  • 'Mail this topic' mailto: link - can be included in topics, templates or skins

  • 'Mail this topic' link text
    • Set MAILTHISTOPICTEXT = Send a link to this page

Registration configuration options

Add user to group during registration

Note, this feature also must be enabled on the UserRegistration page by adding extraField_groups to the optionalFields section. See UserAuthentication#Custom_registration_page for more information.
  • Group type settings during registration:
    • automatic: users will be automatically added to eligible groups
    • one: users can select one of the groups
    • multiple: users can select from multiple groups to join
    • none: user cannot be added to groups while registering

  • If REGISTRATIONGROUPS is set to a comma separated list of groups, only those listed groups will be shown in the UserRegistration form. If it is unset, then group change permissions will be used to create the list of groups eligible for selection during registration. (When using "self-registration" by guest users, the RegistrationAgent's permissions are used. If the registration is entered by another logged in user, that user's permissions are used).

  • Implementation Notes:
    • If the RegistrationAgent or logged in user does not have permission to change one of the listed groups, then that group will be silently skipped. The user will not be added to the group.
    • Group permissions are stored in Topic Settings, not inline in the group topic. Edit the Group Topic Settings to change permissions.

Change of Password Message

  • If password management is not handled by Foswiki, this message will be displayed on ChangePassword and ResetPassword. If email is disabled, it will also be displayed on ResetPassword. Replace this generic text with a reference to how to change or reset password within your organisation.
    • Set CHANGEPASSWORDDISABLEDMESSAGE = Resetting and setting password is not available.


TIP NOTE: Changing cache behaviour with these settings should not be necessary and may cause cache-related problems. These settings do not affect proxy caches.
  • NOTE: The current values of these preferences are not displayed in view mode (values are <link>-tags).

  • http-equiv meta tags for view, rdiff, attach, search* scripts:

  • http-equiv meta tags for edit script:

  • http-equiv meta tags for preview script:

Extension Settings

  • Skin overriding the default templates: (can be overwritten by WebPreferences and user preferences)
    • Set SKIN = natedit,pattern


  • List of Foswiki preferences, the values of which are made available through the foswiki.getPreference() javascript function. Note: Plugin authors can extend this list in their initPlugin using the following simple code fragment. Say you want to add 'MYPREF' to the list:
        my $pref = Foswiki::Func::getPreferencesValue('EXPORTEDPREFERENCES')||'';
        my @list = split(/[,\s]+/, $pref);
        unless (grep { /^MYPREF$/ } @list) {
            push(@list, 'MYPREF');
            'EXPORTEDPREFERENCES', join(',', @list));

  • Top bar background image and color
    • Set WEBHEADERART = /pub/System/PatternSkin/header5.gif
    • Set WEBHEADERBGCOLOR = #ffffff

Skin icons

  • Topic containing the icon graphics library. Icons can easily be rendered with %ICON{name}%.

Miscellaneous Settings

  • Format of a NewWikiWord link:
  • Note that $text is the topic link text, $topic is the name of the new topic, and $web is the name of the web for the new topic. Values for the 3 are taken from the link syntax [[$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

  • PreviewBackground image:
    • Set PREVIEWBGIMAGE = /pub/System/PreviewBackground/preview2bg.gif

  • User-friendly synonyms for system webs
    • Set DOCWEB = System

  • Formatting of revision comparison: sequential, sidebyside or debug
    • Set DIFFRENDERSTYLE = sequential

  • Debug settings for use by Javascript and CSS authors
    • Set FWSRC =
    • Set FWCOMPRESSED = .compressed

  • Redefine these as follows for debugging:
    • #Set FWSRC = _src
    • #Set FWCOMPRESSED = .uncompressed
    • #Set FWUNCOMPRESSED = .uncompressed

Access Control Settings

  • No-one (except admins) should change this topic

Accessible configuration items

Note that any configuration variable accessed via QUERY must be included in the definition of {AccessibleCFG} in configure (expert setting)
  • Set NAMEFILTER = [\\\s*?~^$@%`"'&|<:;>\[\]#\x00-\x1f]

Creating New Preference Settings

You can introduce new preference settings and use them in your topics and templates. There is no need to change the Foswiki engine (Perl scripts).
  • A preference is defined in a bullet item: [3 spaces] * [space] Set NAME = value
    Example (as a nested bullet item, indented 6 spaces):
  • Preferences are used as Macros by enclosing the name in percent signs: %. Example:
    • When you write %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 Wiki administrator e-mail address.

ALERT! In order to protect your custom preferences from being overwritten when upgrading the System.DefaultPreferences topic, it is recommended that all custom settings are defined in Main.SitePreferences.

Protected System Settings

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