TWiki Reference Manual (TWiki-4.0.5, Tue, 24 Oct 2006, build 11822)This page contains all documentation topics as one long, complete reference sheet.Doubleclick anywhere to return to the top of the page.
TWiki System RequirementsServer and client requirements Low client and server base requirements are core features that keep TWiki widely deployable, particularly across a range of browser platforms and versions. Many Plugins and contrib modules exist which enhance and expand TWiki's capabilities; they may have additional requirements.Server RequirementsTWiki is written in Perl 5, uses a number of shell commands, and requires RCS (Revision Control System), a GNU Free Software package. TWiki is developed in a basic Linux/Apache environment. It also works with Microsoft Windows, and should have no problem on any other platform that meets the requirements.
Required CPAN ModulesThe following Perl modules are used by TWiki:
Optional CPAN ModulesThe following Perl modules may be used by TWiki:
configure script, or if you're still trying to get to that point, check from the command line like this:
perl -e 'use FileHandle; print $FileHandle::VERSION."\n"' Client RequirementsThe TWiki standard installation has relatively low browser requirements:

TWiki Installation GuideInstallation instructions for the TWiki 4.0 production release. If you are upgrading from a previous version of TWiki, you probably want to read TWikiUpgradeGuide instead. TWiki should be fine with any web server and OS that meet the system requirements. The following installation instructions are written for experienced system administrators; please review the AdminSkillsAssumptions before you install TWiki. If you need help, ask a question in the TWiki:Support web or on TWiki:Codev.TWikiIRC (irc.freenode.net, channel #twiki) Hint: TWiki:TWiki.InstallingTWiki on TWiki.org has supplemental documentation that help you install TWiki on different platforms, environments and web hosting sites.
Basic Installation

TWiki Upgrade GuideUpgrade from the previous TWiki 01-Sep-2004 Prodcution Release to TWiki-4.0.0OverviewTWiki-4.0.0 is a major new release. You can chose between an automated upgrade using a script or a manual update.Upgrade Requirements
Major Changes Compared to TWiki Release 01-Sep-2004See TWikiReleaseNotes04x00.Automated Upgrade ProcedureIf you would prefer to do things manually, or if you made custom modifications to distributed files (except topics), then skip to the manual upgrade procedure below. The upgrade script is called"UpgradeTwiki", and is found in the root of the distribution. It can be run by any user, though you will need to make sure you correct the permissions so that the webserver user can write all files in the new installation when you have finished. The upgrade script does not write to your existing installation.
The upgrade script will upgrade the TWiki core only. Plugins will need to be upgraded separately.
Note: To upgrade from a Beta, do not use UpgradeTWiki. Instead follow the steps outlined in Upgrading a Beta, below.
It will:
UpgradeTwiki will give you the final instructions.
Visit TWiki:Codev.KnownIssuesOfTWiki04x00x00 and fix known issues that apply to you.
There are a few points worth noting:
Manual Upgrade ProcedureThe following steps are a rough guide to upgrading only. It is impossible to give detailed instructions, as what you have to do may depend on whether you can configure the webserver or not, and how much you have changed distributed files in your current TWiki release.
Upgrading a BetaIf you followed the recommendations and avoided modifying any distributed files, then this is quite straightforward:
Upgrading from Cairo to TWiki4 (additional advice)FaviconTWiki4's PatternSkin introduces the use of the favicon feature which most browsers use to show a small icon in front of the URL and for bookmarks. In TWiki4 it is assumed that each web has a favicon.ico file attached to the WebPreferences topic. When you upgrade from Cairo to TWiki4 you do not have this file and you will get flooded with errors the error log of your web server. There are two solutions to this.
* Set FAVICON = %PUBURLPATH%/%TWIKIWEB%/%WEBPREFSTOPIC%/favicon.ico TWiki User AuthenticationTWiki site access control and user activity tracking optionsOverviewAuthentication, or "login", is the process by which a user lets TWiki know who they are. Authentication isn't just to do with access control. TWiki uses authentication to identify users, so it can keep track of who made changes, and manage a wide range of personal settings. With authentication enabled, users can personalise TWiki and contribute as recognised individuals, instead of shadows. TWiki authentication is very flexible, and can either stand alone or integrate with existing authentication schemes. You can set up TWiki to require authentication for every access, or only for changes. Authentication is also essential for access control. Quick Authentication Test - Use the %WIKIUSERNAME% variable to return your current identity:
 Tip: TWiki:TWiki.TWikiUserAuthenticationSupplement on TWiki.org has supplemental documentation on user authentication.
Password ManagementAs shipped, TWiki supports the Apache 'htpasswd' password manager. This manager supports the use of.htpasswd files on the server. These files can be unique to TWiki, or can be shared with other applications (such as an Apache webserver). A variety of password encodings are supported for flexibility when re-using existing files. See the descriptive comments in the Security Settings section of the configure interface for more details.
New User RegistrationNew user registration uses the password manager to set and change passwords. It is also responsible for the new user verification process. the registration process supports single user registration via the TWikiRegistration page, and bulk user registration via the BulkRegistration page (for admins only). The registration process is responsible for creating user topics.Login ManagementLogin management controls the way users have to log in. There are three basic options; no login, login via a TWiki login page, and login using the webserver authentication support. You can select your chosen login through the Security Settings pane in theconfigure interface.
No Login (select
Does exactly what it says on the tin. Forget about authentication to make your site completely public - anyone can browse and edit freely, in classic Wiki style. All visitors are given the TWikiGuest default identity, so you can't track individual user activity.

- A blank in the the above table may mean either the corresponding control is absent or commented out or that it has been set to a null value. The two conditions have dramatically different and possibly opposed semantics.
- TWikiGuest is the guest account - used by unauthenticated users.
- The TWiki web must not deny view to TWikiGuest; otherwise, people will not be able to register.
Authentication vs. Access Control
Authentication: Identifies who a user is based on a login procedure. See TWikiUserAuthentication. Access control: Restrict access to content based on users and groups once a user is identified.Users and Groups
Access control is based on the familiar concept of Users and Groups. Users are defined by their WikiNames. They can then be organized in unlimited combinations by inclusion in one or more user Groups. For convenience, Groups can also be included in other Groups.Managing Users
A user can create an account in TWikiRegistration. The following actions are performed:- WikiName and encrypted password are recorded using the password manager if authentication is enabled.
- A confirmation e-mail is sent to the user.
- A user home page with the WikiName of the user is created in the User web.
- The user is added to the TWikiUsers topic.
Managing Groups
Groups are defined by group topics located in theUser web, such as the TWikiAdminGroup. To create a new group, visit TWikiGroups and enter the name of the new group ending in Group into the "new group" form field. This will create a new group topic with two important settings: -
Set GROUP = < list of Users and/or Groups > -
Set ALLOWTOPICCHANGE = < list of Users and/or Groups >
-
Set GROUP = User.SomeUser, User.OtherUser, User.SomeGroup
-
Set ALLOWTOPICCHANGE = User.TWikiAdminGroup
Note: TWiki has strict formatting rules. Make sure you have three spaces, an asterisk, and an extra space in front of any access control rule.
The Super Admin Group
By mistyping a user or group name in the settings, it's possible to lock a topic so that no-one can edit it from a browser. To avoid this, add the WikiNames of registered administrators to the super admin group topic calledTWikiAdminGroup. The name of this topic is defined by the {SuperAdminGroup} configure setting. Example group setting: -
Set GROUP= User.ElizabethWindsor, User.TonyBlair
Restricting Access
You can define who is allowed to read or write to a web or a topic. Note that some plugins may not respect access permissions.- Restricting VIEW blocks viewing and searching of content.
- Restricting CHANGE blocks creating new topics, changing topics or attaching files.
- Restricting RENAME controls who is allowed to rename, move or delete a topic.
- To rename, move or delete a topic, the user also also needs VIEW and CHANGE permission. They also need CHANGE access to change references in any referring topics (though the rename can proceed without this access), and CHANGE access to the target topic.
- Restricting MANAGE controls access to certain management functions, such as 'create web'. It must be set in the TWiki web.
Controlling access to a Web
You can define restrictions of who is allowed to view a TWiki web. You can restrict access to certain webs to selected Users and Groups, by:- authenticating all webs and restricting selected webs: Topic access in all webs is authenticated, and selected webs have restricted access.
- authenticating and restricting selected webs only: Provide unrestricted viewing access to open webs, with authentication and restriction only on selected webs.
- You can define these settings in the WebPreferences topic, preferable towards the end of the topic:
-
Set DENYWEBVIEW = < comma-delimited list of Users and Groups > -
Set ALLOWWEBVIEW = < comma-delimited list of Users and Groups > -
Set DENYWEBCHANGE = < comma-delimited list of Users and Groups > -
Set ALLOWWEBCHANGE = < comma-delimited list of Users and Groups > -
Set DENYWEBRENAME = < comma-delimited list of Users and Groups > -
Set ALLOWWEBRENAME = < comma-delimited list of Users and Groups >
-
-
Set ALLOWWEBVIEW =
-
Set DENYWEBVIEW =
Controlling access to a Topic
- You can define these settings in the WebPreferences topic, preferable towards the end of the topic:
-
Set DENYTOPICVIEW = < comma-delimited list of Users and Groups > -
Set ALLOWTOPICVIEW = < comma-delimited list of Users and Groups > -
Set DENYTOPICCHANGE = < comma-delimited list of Users and Groups > -
Set ALLOWTOPICCHANGE = < comma-delimited list of Users and Groups > -
Set DENYTOPICRENAME = < comma-delimited list of Users and Groups > -
Set ALLOWTOPICRENAME = < comma-delimited list of Users and Groups >
-
-
Set ALLOWTOPICVIEW =
-
Set DENYTOPICVIEW =
Controlling access to Attachments
Attachments are referred to directly, and are not normally indirected via TWiki scripts. This means that the above instructions for access control will not apply to attachments. It is possible that someone may inadvertently publicise a URL that they expected to be access-controlled. The easiest way to apply the same access control rules for attachments as apply to topics is to use the Apachemod_rewrite module, and configure your webserver to redirect accesses to attachments to the TWiki viewfile script. For example,
ScriptAlias /twiki/bin/ /filesystem/path/to/twiki/bin/
Alias /twiki/pub/ /filesystem/path/to/twiki/pub/
RewriteEngine on
RewriteCond %{REQUEST_URI} !^/+twiki/+pub/+TWiki/+.+
RewriteRule ^/+twiki/+pub/+([^/]+)/+((([^/]+)/+)+)(.+) /twiki/bin/viewfile/$1/$4?filename=$5 [L,PT]
</verbatim
That way all the controls that apply to the topic also apply to attachments to the topic. Other types of webserver have similar support.
__Note:__ Images embedded in topics will load much slower since each image will be delivered by the =viewfile= script.
---+++ How TWiki evaluates ALLOW/DENY settings
When deciding whether to grant access, TWiki evaluates the following rules in order (read from the top of the list; if the logic arrives at *PERMITTED* or *DENIED* that applies immediately and no more rules are applied). You need to read the rules bearing in mind that VIEW, CHANGE and RENAME access may be granted/denied separately.
1 If the user is a [[#SuperAdminGroup][super-user]]
* access is *PERMITTED*.
1 If DENYTOPIC is set to a list of wikinames
* people in the list will be *DENIED*.
1 If DENYTOPIC is set to _empty_ ( i.e. <tt>Set DENYTOPIC =</tt> )
* access is *PERMITTED* _i.e_ no-one is denied access to this topic
1 If ALLOWTOPIC is set
1 people in the list are *PERMITTED*
1 everyone else is *DENIED*
* Note that this means that setting ALLOWTOPIC to empty _denies access to everyone except admins_ (unless DENYTOPIC is also set to empty, as described above)
1 If DENYWEB is set to a list of wikiname
* people in the list are *DENIED* access
1 If ALLOWWEB is set to a list of wikinames
* people in the list will be *PERMITTED*
* everyone else will be *DENIED*
* Note that setting ALLOWWEB to empty _denies access to everyone except admins_
1 If you got this far, access is *PERMITTED*
---++ Access Control quick recipes
---+++ Obfuscating Webs
Another way of hiding webs is to keep them hidden by not publishing the URL and by preventing the ==all webs== search option from accessing obfuscated webs. Do so by enabling the ==NOSEARCHALL== variable in %WEBPREFSTOPIC%:
* ==Set <nop>NOSEARCHALL = on==
This setup can be useful to hide a new web until content its ready for deployment, or to hide view access restricted webs.
__%X% Note:__ Obfuscating a web without view access control is *very* insecure, as anyone who knows the URL can access the web.
---+++ Authenticate all Webs and Restrict Selected Webs
Use the following setup to authenticate users for topic viewing in all webs and to restrict access to selected webs. Requires TWikiUserAuthentication to be enabled.
1. *Restrict* view access to selected Users and Groups. Set one or both of these variables in its %WEBPREFSTOPIC% topic:
* ==Set <nop>DENYWEBVIEW = < list of Users and Groups >==
* ==Set <nop>ALLOWWEBVIEW = < list of Users and Groups >==
* __Note:__ =DENYWEBVIEW= is evaluated before =ALLOWWEBVIEW=. Access is denied if the authenticated person is in the =DENYWEBVIEW= list, or not in the =ALLOWWEBVIEW= list. Access is granted in case =DENYWEBVIEW= and =ALLOWWEBVIEW= is not defined.
---+++ Authenticate and Restrict Selected Webs Only
Use the following setup to provide unrestricted viewing access to open webs, with authentication only on selected webs. Requires TWikiUserAuthentication to be enabled.
1. *Restrict* view access to selected Users and Groups. Set one or both of these variables in its %WEBPREFSTOPIC% topic:
* ==Set <nop>DENYWEBVIEW = < list of Users and Groups >==
* ==Set <nop>ALLOWWEBVIEW = < list of Users and Groups >==
* __Note:__ =DENYWEBVIEW= is evaluated before =ALLOWWEBVIEW=. Access is denied if the authenticated person is in the =DENYWEBVIEW= list, or not in the =ALLOWWEBVIEW= list. Access is granted in case =DENYWEBVIEW= and =ALLOWWEBVIEW= is not defined.
---+++ Hide Control Settings
__%T% Tip:__ To hide access control settings from normal browser viewing, place them in HTML comment markers.
<blockquote>
==<!--== <br />
== * Set <nop>DENYTOPICCHANGE = %MAINWEB%.<nop>SomeGroup== <br />
==-->==

TWiki Text Formatting
Working in TWiki is as easy as typing in text. You don't need to know HTML, though you can use it if you prefer. Links to topics are created automatically when you enter WikiWords. And TWiki shorthand gives you all the power of HTML with a simple coding system that takes no time to learn. It's all laid out below.TWiki Editing Shorthand
| Formatting Command: | You write: | You get: | |||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
Paragraphs: Blank lines will create new paragraphs. |
1st paragraph 2nd paragraph | 1st paragraph 2nd paragraph | |||||||||||||||||||||||||
|
Headings: Three or more dashes at the beginning of a line, followed by plus signs and the heading text. One plus creates a top level heading, two pluses a second level heading, etc. The maximum heading depth is 6. You can create a table of contents with the %TOC% variable. If you want to exclude a heading from the TOC, put !! after the ---+.
Empty headings are allowed, but won't appear in the table of contents.

WikiWord Links: CapitalizedWordsStuckTogether (or WikiWords) will produce a link automatically if preceded by whitespace or parenthesis. If you want to link to a topic in a different web write Otherweb.TopicName. The link label excludes the name of the web, e.g. only the topic name is shown. As an exception, the name of the web is shown for the WebHome topic.
It's generally a good idea to use the TWikiVariables %TWIKIWEB% and %MAINWEB% instead of TWiki and Main.

|
Anchors: You can define a reference inside a TWiki topic (called an anchor name) and link to that. To define an anchor write #AnchorName at the beginning of a line. The anchor name must be a WikiWord. To link to an anchor name use the [[MyTopic#MyAnchor]] syntax. You can omit the topic name if you want to link within the same topic.
|
[[WikiWord#NotThere]] [[#MyAnchor][Jump]] #MyAnchor To here | WikiWord#NotThere Jump To here | |||||||||||||||||||||||||
|
Forced Links: You can create a forced internal link by enclosing words in double square brackets. Text within the brackets may contain optional spaces; the topic name is formed by capitalizing the initial letter and by removing the spaces; for example, [[text formatting FAQ]] links to topic TextFormattingFAQ. You can also refer to a different web and use anchors.
To "escape" double square brackets that would otherwise make a link, prefix the leading left square bracket with an exclamation point.

|
Specific Links: You can create a link where you specify the link text and the URL separately using nested square brackets [[reference][text]]. Internal link references (e.g. WikiSyntax) and URLs (e.g. http://TWiki.org/) are both supported.
The rules described under Forced Links apply for internal link references.
Anchor names can be added as well, to create a link to a specific place in a topic.

Using HTML
You can use just about any HTML tag without a problem. You can add HTML if there is no TWiki equivalent, for example, write<strike>deleted text</strike> to get There are a few usability and technical considerations to keep in mind: - On collaboration pages, it's better not to use HTML, but to use TWiki shorthand instead - this keeps the text uncluttered and easy to edit.
- If you use HTML use XHTML 1.0 Transitional syntax.
- Script tags may be filtered out, at the discretion of your TWiki administrator.
- Copy only text between
<body>and</body>tags. - Remove all empty lines. TWiki inserts
<p />paragraph tags on empty lines, which causes problems if done between HTML tags that do not allow paragraph tags, like for example between table tags. - Remove leading spaces. TWiki might interpret some text as lists.
- Do not span a tag over more than one line. TWiki requires that the opening and closing angle brackets -
<...>- of an HTML tag are on the same line, or the tag will be broken. - In your HTML editing program, save without hard line breaks on text wrap.
TWiki converts shorthand notation to HTML for display. To copy a fully marked-up page, simply view the source in your browser and save the contents. If you need to save HTML frequently, you may want to check out TWiki:Plugins/PublishAddOn.
Script tags
You can use HTML<script> tags for your TWiki applications. However note that your TWiki administrator can disable <script> in topics, and may have chosen to do so for security considerations. TWiki markup and TWikiVariables are not expanded inside script tags.
Hyperlinks
Being able to create links without any special formatting is a core TWiki feature, made possible with WikiWords and inline URLs.Internal Links
- NotExistingYet? is a topic waiting to be written. Create the topic by clicking on the ?. (Try clicking, but then, Cancel - creating the topic would wreck this example!)
External Links
-
http://...,https://...,ftp://...,gopher://...,news://...,file://...,telnet://...andmailto:...@...are linked automatically.
- E-mail addresses like
name@domain.comare linked automatically.
-
[[Square bracket rules]]let you easily create non-WikiWord links.- You can also write
[[http://yahoo.com Yahoo home page]]as an easier way of doing external links with descriptive text for the link, such as Yahoo home page.
- You can also write
TWiki Variables
TWiki Variables are names that are enclosed in percent signs% that are expanded on the fly. Some variables take arguments, such as %INCLUDE%. For those variables, the arguments are included in curly braces ({ and }).
| Variable | In brief | Full documentation |
|---|---|---|
%TOC% | Automatically generates a table of contents based on headings in a topic - see the top of this page for an example. | VarTOC |
%WEB% | The current web, is TWiki. | VarWEB |
%TOPIC% | The current topic name, is TWikiDocumentation. | VarTOPIC |
%ATTACHURL% | The attachment URL of the current topic. Example usage: If you attach a file to a topic you can refer to it as %ATTACHURL%/image.gif to show the URL of the file or the image in your text. | VarATTACHURL |
%INCLUDE{"SomeTopic"}% | Server side include, includes another topic. The current web is the default web. Example: %INCLUDE{"TWiki.SiteMap"}% | VarINCLUDE |
%SEARCH{"sushi"}% | Inline search showing the search result embedded in a topic. FormattedSearch gives you control over formatting, useful for creating web-based applications. | VarSEARCH |
- Line break: Write
%BR%to start a new line. - Colored text: Write:
%RED% Red %ENDCOLOR% and %BLUE% blue %ENDCOLOR% colorsto get: Red and blue colors.
%ICON{"help"}%, %ICON{"tip"|%, and %icon{"warning"}% to get: , , and . To see all of the graphics available, see TWikiDocGraphics.
To "escape" a variable, prefix it with an exclamation mark. Write: !%SOMEVARIABLE% to get: %SOMEVARIABLE%.

Common Editing Errors
TWiki formatting rules are fairly simple to use and quick to type. However, there are some things to watch out for, taken from the TextFormattingFAQ:- Q:
