TWiki . Main . WebPreferences	TWiki webs: Main | TWiki | Test
	Main . { Main . { Home | Users | Changes | Index | Search | Go } }

The following settings are web preferences of the TWiki.Main web. These preferences overwrite the site-level preferences in TWikiPreferences, and can be overwritten by user preferences (your personal topic, i.e. TWikiGuest in the TWiki.Main web)

Preferences:

• List of topics of the TWiki.Main web:
  • Set WEBTOPICLIST = Main . { Home | Users | Changes | Index | Search | Go }

• Web specific background color: (Pick a lighter one of the StandardColors)
  • Set WEBBGCOLOR = #6699CC

• Exclude web from a web="all" search: (Set to on for hidden webs)
  • Set NOSEARCHALL =

• Users or groups who are not / are allowed to change topics in the Main web: (See TWikiAccessControl)
  • Set DENYWEBCHANGE =
  • Set ALLOWWEBCHANGE =

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

• Web preferences that are not allowed to be overridden by user preferences:
  • Set FINALPREFERENCES = WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE

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 #6699CC .
• 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 preferences variables and use them in your topics and templates. There is no need to change the TWiki engine (Perl scripts).
