Preferences:

• List of TWiki webs: (the first line of a topic; to add a web see TWikiDocumentation and TWikiWebsTable)
  • Set WIKIWEBLIST = Main | TWiki | Know | Test?
  • Note: To automatically list all non-hidden webs in alphabetical order you can use this variable instead: Set WIKIWEBLIST = Know| Main | Sandbox | TWiki |

  • 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)

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

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

• 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, InterwikiPlugin
  • Note: In case you have a rough plugin you can disable all plugins with the $disableAllPlugins flag in the TWiki.cfg file.

      * Set HTTP_EQUIV_ON_VIEW = 

• http-equiv meta tags for edit script. Example to expire immediately:
  Set HTTP_EQUIV_ON_EDIT = <meta http-equiv="Expires" content="%GMTIME{"$day $month, $year - $hour:$min:$sec"}% GMT">

      * Set HTTP_EQUIV_ON_EDIT = 

• http-equiv meta tags for preview script:

      * Set HTTP_EQUIV_ON_PREVIEW = 

• Users or groups allowed to change this TWikiPreferences topic: (I.e. TWikiAdminGroup)
  • Set ALLOWTOPICCHANGE =

• Users or groups allow to rename this TWikiPreferences topic:
  • #Set ALLOWTOPICRENAME = TWikiAdminGroup

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

Notes:

• A preference is defined as:
  6 spaces * Set NAME = value
  Example:
  • 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 #FFE0B0 .
• The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
• You can introduce new variables and use them in your topics and templates. There is no need to change the TWiki engine (Perl scripts).
