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.

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
- NOTE: You can enable/disable all plugins with the $disableAllPlugins flag in the lib/TWiki.cfg file.

http-equiv meta tags for preview script:

      * Set HTTP_EQUIV_ON_PREVIEW =

- Set ALLOWTOPICRENAME =

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

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.
