TWiki Site-Level Preferences

The following are site-level settings that affect all users in all webs on this TWikiSite. They can be selectively overwritten on the individual web level (see WebPreferences in each web), and on the user level (create preferences in your user account topic in the Main web, ex: Main.guest).

• NOTE: You can lock individual settings at the site or web levels using User & Group Access Control - see section below.

General Preferences

• List of TWiki webs - on the first line of the upper toolbar (to add a new web, see ManagingWebs and SiteMap):

  • Set RELEASEEDITLOCKCHECKBOX =

• 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)
  • Set DONTNOTIFYCHECKBOX =

• 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)

Email Settings

• TWiki webmaster email address:
  • Set WIKIWEBMASTER = webmaster@your.company

• Mail host for outgoing mail. This is used for WebChangesAlert if Perl module Net::SMTP is installed. If not, or if SMTPMAILHOST is empty, the external sendmail program is used instead (defined by $mailProgram in TWiki.cfg). Examples: mail.your.company or localhost
  • Set SMTPMAILHOST = mail

• Mail domain sending mail. SMTP requires that you identify the TWiki server sending mail. If not set, Net::SMTP will guess it for you. Ex: twiki.your.company
  • Set SMTPSENDERHOST =

Plugins Settings

• TWikiPlugins configuration: All plugin modules that exist in the lib/TWiki/Plugins directory are activated automatically unless disabled by DISABLEDPLUGINS. You can optionally list the installed plugins in INSTALLEDPLUGINS. This is useful to define the sequence of plugin execution, or to specify other webs then the TWiki web for the plugin topics. Specify plugins as a comma separated list of topics.
  • Set INSTALLEDPLUGINS = DefaultPlugin
  • Set DISABLEDPLUGINS = EmptyPlugin
  • Currently activated plugins: DefaultPlugin, SpreadSheetPlugin, CommentPlugin, EditTablePlugin, InterwikiPlugin, RenderListPlugin, SlideShowPlugin, SmiliesPlugin, TablePlugin

      * Set HTTP_EQUIV_ON_EDIT = 

• http-equiv meta tags for preview script:

      * Set HTTP_EQUIV_ON_PREVIEW = 

Miscellaneous Settings

• Graphics used in TWiki documentation - view all images in TWikiDocGraphics. (There are various ways to set up common icons as text variables. This is simply one quick approach.):
  • Set H =
  • Set I =
  • Set M =
  • Set N =
  • Set P =
  • Set Q =
  • Set S =
  • Set T =
  • Set U =
  • Set X =
  • Set Y =
  • Set TLS =

  You type:	%RED% red text %ENDCOLOR% and %GREEN% green text %ENDCOLOR%
  You get:	red text and green text

  • Note: %<color>% text must end with %ENDCOLOR% . If you want to switch from one color to another one you first need to end the active color with %ENDCOLOR%, e.g. write %RED% some text %ENDCOLOR% %GREEN% more text %ENDCOLOR%.
  • Set YELLOW =
    • YELLOW looks like this
  • Set RED =
    • RED looks like this
  • Set PINK =
    • PINK looks like this
  • Set PURPLE =
    • PURPLE looks like this
  • Set TEAL =

  • Set GRAY =

  • Set SILVER =

  • Set WHITE =
    • WHITE looks like this
  • And finally:
  • Set ENDCOLOR =
    • To finish colored text

Preferences Access Control

• Users or groups allowed to change or rename this TWikiPreferences topic: (ex: TWikiAdminGroup)
  • Set ALLOWTOPICCHANGE =
  • Set ALLOWTOPICRENAME =

• Users or groups allowed to create new webs: (ex: TWikiAdminGroup)
  • Set ALLOWWEBCREATEWEB = TWikiAdminGroup

• Site-level preferences that are not allowed to be overridden by WebPreferences and user preferences:
  • Set FINALPREFERENCES = PREVIEWBGIMAGE, WIKIWEBMASTER, SMTPMAILHOST , SMTPSENDERHOST, ALLOWWEBCREATEWEB

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 webmaster email address.
