# %WIKITOOLNAME% 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.admin). - %X% **NOTE:** You can lock individual settings at the site or web levels using User & Group Access Control - see section below.
**$name**
gets expanded to filename; **$comment**
to comment; **\\t**
to tab (3 spaces for bullets).
- Format of images when the **_link_** check box is checked: (can be overwritten by user preferences)
- Set ATTACHEDIMAGEFORMAT = \\t\* $comment: **$name**
gets expanded to filename; **$comment**
to comment; **$size**
to **width="..." height="..."**
attribute of **img**
tag; **\\t**
to tab (3 spaces for bullets).
## Email Settings
- TWiki webmaster email address:
- Set WIKIWEBMASTER = **Net::SMTP**
is installed. If not, or if `SMTPMAILHOST` is empty, the external sendmail program is used instead (defined by **$mailProgram**
in **TWiki.cfg**
). Examples: **mail.your.company**
or **localhost**
- Set SMTPMAILHOST = mail
- Mail domain sending mail. SMTP requires that you identify the TWiki server sending mail. If not set, **Net::SMTP**
will guess it for you. Ex: **twiki.your.company**
- Set SMTPSENDERHOST =
## Plugins Settings
- [[TWikiPlugins]] configuration: All plugin modules that exist in the `lib/TWiki/Plugins` directory are activated automatically unless disabled by DISABLEDPLUGINS. You can optionally list the installed plugins in INSTALLEDPLUGINS. This is useful to define the sequence of plugin execution, or to specify other webs then the TWiki web for the plugin topics. Specify plugins as a comma separated list of topics.
- Set INSTALLEDPLUGINS = [[DefaultPlugin]]
- Set DISABLEDPLUGINS = [[EmptyPlugin]]
- Currently activated plugins: [[SpreadSheetPlugin]], [[CommentPlugin]], [[EditTablePlugin]], [[InterwikiPlugin]], [[PreferencesPlugin]], [[SlideShowPlugin]], [[SmiliesPlugin]], [[TablePlugin]], [[TwistyPlugin]]
- %T% **NOTE:** You can enable/disable all plugins with the **$disableAllPlugins**
flag in the **lib/TWiki.cfg**
file.
## HTTP-EQUIV Settings
- **http-equiv**
meta tags for **view**
, **rdiff**
, **attach**
, **search\***
scripts:
* Set HTTP_EQUIV_ON_VIEW =
- **http-equiv**
meta tags for **edit**
script. Example, to expire immediately: **http-equiv**
meta tags for **preview**
script:
* Set HTTP_EQUIV_ON_PREVIEW =
## Preferences Access Control
- Users or groups allowed to change or rename this %TOPIC% topic: (ex: [[TWikiAdminGroup]])
- Set ALLOWTOPICCHANGE =
- 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:
- When you write variable **%WEBBGCOLOR%**
, it gets expanded to `%WEBBGCOLOR%` .
- %X% 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.
