This topic defines site-level settings that apply to all users and webs on this TWiki Site.
Note: This topic should be regarded as read-only, so that upgrades can safely overwrite it without risk to your customizations.
Preference settings local to your site should be set in Main.TWiki Preferences (this topic is pointed to by {LocalSitePreferences}, which is set by the admin in the configure interface). Settings in Main.TWiki Preferences will override settings in this topic, and should be used for defining custom settings and variables.

If yes, set SITEMAPLIST to on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Make sure to list only links that include the name of the web, e.g. TWiki.Topic links.
Simplified Copyright notice for the Web Rss feed (don't use any special characters, html tags, entities, wiki markup or Wiki Words)
Set WEBRSSCOPYRIGHT = Copyright 2010 by contributing authors
Exclude web from a web="all" search: (Set to on for hidden webs; is overwritten by web preferences) Note it is much better to use TWiki Access Controls in individual webs to control who can and can't view the contents of a web. NOSEARCHALL is retained for compatibility, but you should avoid using it.
Set NOSEARCHALL =
Prevent automatic linking of WikiWords and acronyms (if set to on); link WikiWords (if empty); can be overwritten by web preferences:
Set NOAUTOLINK =
Note: Use the [[...][...]] syntax to link topics in case you disabled WikiWord linking. The <noautolink> ... </noautolink> syntax can be used to prevents links within a block of text.
If you use non WikiWords for topic names (for example "Expenses" or "Mighty1") and if you use bracket notation to link to those topics, it is useful to turn of all warnings (like: "WARNING: This topic name is not recommended because it will not be linked automatically") and checkboxes ("Allow non WikiWord for the new topic name"). Can be overwritten by web preferences. Set to on to activate:
Set HIDE_NON_WIKI_WORD_WARNINGS =
Warn if %INCLUDE{}% of topic fails: Fail silently if empty or off. Output warning message (defined in templates/oopsalerts.tmpl) if set to on. Otherwise output specific text (use $topic for topic). You can override this in web preferences, or by using a warn="..." parameter with %INCLUDE{}% :
Set INCLUDEWARNING = on
Generated Table of Contents (TOC) settings
The first header level to appear in the TOC:
Set TOC_MIN_DEPTH =
If not set: 1
Possible values: 1 to 6
The last header level to appear in the TOC:
Set TOC_MAX_DEPTH =
If not set: 6
Possible values: 1 to 6
Can be overridden by depth parameter of variable TOC
The default TOC title:
Set TOC_TITLE =
If not set: nothing
Possible values: any string, for example On this page:
Can be overridden by title parameter of variable TOC
Do not show a TOC if the topic it contains is included in another topic:
Set TOC_HIDE_IF_INCLUDED =
If not set: included TOC is shown
Possible values: on or nothing
Default User Settings
NOTE: They are typically redefined in topics of individual TWiki Users
Show tool-tip topic info on mouse-over of Wiki Word links. Setting can be on, off, or customized. An empty setting or off setting disables the tool-tips (for better performance). The setting can contain $summary to show the topic summary, $date for the last change date, $rev for the revision, $username for the login name of the last editor, $wikiname for the WikiName, $wikiusername for Main.WikiName, $topic for the topic name, and $web for the web name
Horizontal size of text edit box: (can be overwritten by user preferences)
Set EDITBOXWIDTH = 70
Vertical size of text edit box: (can be overwritten by user preferences)
Set EDITBOXHEIGHT = 22
Style of text edit box. Set to width: 99% for full window width (default; this will overwrite the EDITBOXWIDTH setting), or width: auto to disable. This setting works for IE and some other recent browsers. (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)
Set ATTACHLINKBOX =
Format of file link when the link check box is checked: (can be overwritten by user preferences)
NOTE: Keyword $name gets expanded to filename; $comment to comment; \t to tab (3 spaces for bullets).
* Set ATTACHEDFILELINKFORMAT = \n * [[%ATTACHURL%/$name][$name]]: $comment
Format of images when the link check box is checked: (can be overwritten by user preferences)
NOTE: Keyword $name gets expanded to filename; $comment to comment; $size to width="..." height="..." attribute of img tag; \t to tab and \n to linefeed (3 spaces for bullets).
Image, URL and alternate tooltip text of the logo for this installation: you should change these settings for your site, or they can be overwridden in WebPreferences for individual webs by defining these variables there.
Set WIKILOGOIMG = /pub/TWiki/TWikiPreferences/screen.gif
Broadcast message for skins supporting a %BROADCASTMESSAGE% at the top of the page: (IMPORTANT: Set to empty message if not used; #Comment out unused messages)
Set BROADCASTMESSAGE =
#Set BROADCASTMESSAGE = NOTE: Edit and Attach will be disabled today between 05:00 PM and 06:00 PM PDT (00:00 to 01:00 GMT) for a scheduled TWiki maintenance.
Users or groups allowed to create new top-level webs: (ex: Web Creators Group? ). If set to nothing, only administrators will be able to do this.

Set SEARCHSTOPWORDS = a, all, am, an, and, any, as, at, b, be, by, c, d, e, for, from, g, h, how, i, i'm, i.e., in, is, isn't, it, it's, its, j, k, l, m, n, o, of, on, or, p, q, r, s, t, that, that's, the, this, to, u, v, w, was, wasn't, what, what's, when, where, who, who's, will, with, x, y, z
E-mail Settings
'Mail this topic' mailto: link - can be included in topics, templates or skins
You can enable/disable Plugins using the configure interface.
You can also disable installed plugins in individual webs/topics by defining the %DISABLEDPLUGINS% TWiki variable to be a list of plugins to disable e.g.
Set INSTALLEDPLUGINS = The INSTALLEDPLUGINS variable is no longer supported. You can set the Plugins execution order using the configure interface.
Rendering Shortcuts Settings
Line break: Note that the setting has an intentional trailing space
Set BR =
Bullet sign:
Set BULLET = •
Vertical bar / pipe symbol:
Set VBAR = |
Vertical caret symbol:
Set CARET = ^
Line break and bullet with different levels of indentation:
Set BB = •
Set BB2 = •
Set BB3 = •
Set BB4 = •
Hint: Above shortcuts are useful in TWiki tables where you cannot use newlines
Graphics used in TWiki documentation - view all images in TWiki Doc Graphics. (There are various ways to set up common icons as text variables. This is simply one quick approach.):
%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 = looks like this
Set ORANGE = looks like this
Set RED = looks like this
Set PINK = looks like this
Set PURPLE = looks like this
Set TEAL = looks like this
Set NAVY = looks like this
Set BLUE = looks like this
Set AQUA = looks like this
Set LIME = looks like this
Set GREEN = looks like this
Set OLIVE = looks like this
Set MAROON = looks like this
Set BROWN = looks like this
Set BLACK = looks like this
Set GRAY = looks like this
Set SILVER = looks like this
Set WHITE = looks like this (with gray background)
The following color settings are enclosed in verbatim tags to avoid incorrect nesting of XHTML tags:
* Set YELLOW = <font color="#ffff00">
* Set ORANGE = <font color="#ff6600">
* Set RED = <font color="#ff0000">
* Set PINK = <font color="#ff00ff">
* Set PURPLE = <font color="#800080">
* Set TEAL = <font color="#008080">
* Set NAVY = <font color="#000080">
* Set BLUE = <font color="#0000ff">
* Set AQUA = <font color="#00ffff">
* Set LIME = <font color="#00ff00">
* Set GREEN = <font color="#008000">
* Set OLIVE = <font color="#808000">
* Set MAROON = <font color="#800000">
* Set BROWN = <font color="#996633">
* Set BLACK = <font color="#000000">
* Set GRAY = <font color="#808080">
* Set SILVER = <font color="#c0c0c0">
* Set WHITE = <font color="#ffffff">
* Set ENDCOLOR = </font>
Note that $text is the topic link text, $topic is the name of the new topic, and $web is the name of the web for the new topic. Values for the 3 are taken from the link syntax [[$web.$topic][$text]]. For normal plain WikiWord links $text and $topic are the same. The value of $web is the current web unless the link is in the format $web.$topic.
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 TWiki Shorthand bullet item: [3 spaces] * [space] Set NAME = value Example (as a nested bullet item, indented 6 spaces):
Set WEBBGCOLOR = #FFFFC0
Preferences are used as TWiki Variables 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 TWiki administrator e-mail address.
In order to protect your custom variables from being overwritten when upgrading the TWiki.TWiki Preferences topic, it is recommended that custom variables are defined in Main.TWiki Preferences.
Protected System Settings
The following settings are declared final to protect them as read only. These are system variables that should never be attempted set or altered in any preference topic or topic settings.
Note: This topic should be regarded as read-only, so that upgrades can safely overwrite it without risk to your customizations.
Preference settings local to your site should be set in Main.TWiki Preferences (this topic is pointed to by {LocalSitePreferences}, which is set by the admin in the configure interface). Settings in Main.TWiki Preferences will override settings in this topic, and should be used for defining custom settings and variables.
