This module defines official functions that Plugins can use to interact with the TWiki engine and content.

Refer to EmptyPlugin and lib/TWiki/Plugins/EmptyPlugin.pm for a template Plugin and documentation on how to write a Plugin.

Plugins should only use functions published in this module. If you use functions in other TWiki libraries you might create a security hole and you will probably need to change your Plugin when you upgrade TWiki.

Deprecated functions will still work in older code, though they should not be called in new Plugins and should be replaced in older Plugins as soon as possible.

The version of the TWiki::Func module is defined by the VERSION number of the TWiki::Plugins module, currently 1.1. This can be shown by the %PLUGINVERSION% variable. The 'Since' field in the function documentation refers to the VERSION number and the date that the function was addded.

Note: Beware! These methods should only ever be called from the context of a TWiki Plugin. They require a Plugins SESSION context to be established before they are called, and will not work if simply called from another TWiki module. For example,

use TWiki;
print TWiki::Func::getSkin(),"\n";

If you want to call the methods outside the context of a plugin, you can create a Plugins SESSION object. For example, the script:

use TWiki:
$TWiki::Plugins::SESSION = new TWiki();
print TWiki::Func::getSkin(),"\n";

Environment

getSkin( ) -> $skin

Get the skin path, set by the SKIN and COVER preferences variables or the skin and cover CGI parameters

Return: $skin Comma-separated list of skins, e.g. 'gnu,tartan'. Empty string if none.

Since: TWiki::Plugins::VERSION 1.000 (29 Jul 2001)

getUrlHost( ) -> $host

Get protocol, domain and optional port of script URL

Return: $host URL host, e.g. "http://example.com:80"

• $param1 ... $param4 - Parameter values for %PARAM1% ... %PARAMn% variables in template, optional

This might be used like this:

   my $url = TWiki::Func::getOopsUrl($web, $topic, 'oopsmistake', 'I made a boo-boo');

   return 0;

Since: TWiki::Plugins::VERSION 1.000 (7 Dec 2002)

Since TWiki::Plugins::VERSION 1.1, the recommended approach is to throw an oops exception.

Since: TWiki::Plugins::VERSION 1.1

getContext() -> \%hash

The context is a set of identifiers that are set during specific phases of TWiki processing. For example, each of the standard scripts in the 'bin' directory each has a context identifier - the view script has 'view', the edit script has 'edit' etc. So you can easily tell what 'type' of script your Plugin is being called within. The core context identifiers are listed in the TWikiTemplates topic. Please be careful not to overwrite any of these identifiers!

Context identifiers can be used to communicate between Plugins, and between Plugins and templates. For example, in FirstPlugin^?.pm, you might write:

sub initPlugin {
   TWiki::Func::getContext()->{'MyID'} = 1;
   ...

sub initPlugin {
   if( TWiki::Func::getContext()->{'MyID'} ) {
      ...
   }
   ...

%TMPL:DEF{"ON"}% Not off %TMPL:END%
%TMPL:DEF{"OFF"}% Not on %TMPL:END%
%TMPL:P{context="MyID" then="ON" else="OFF"}%

%IF{"context MyID" then="MyID is ON" else="MyID is OFF"}%

    # see documentation on Error::Simple
} catch TWiki::AccessControlException with {
    my $e = shift;
    # see documentation on TWiki::AccessControlException
} otherwise {
    ...
};

To delete a web, move it to a subweb of Trash

TWiki::Func::moveWeb( "Deadweb", "Trash.Deadweb" );

getTopicList( $web ) -> @topics

Get list of all topics in a web

• $web - Web name, required, e.g. 'Sandbox'

setTopicEditLock( $web, $topic, $lock )

• $web Web name, e.g. "Main", or empty
• $topic Topic name, e.g. "MyTopic", or "Main.MyTopic"
• $lock 1 to lease the topic, 0 to clear the lease=

Takes out a "lease" on the topic. The lease doesn't prevent anyone from editing and changing the topic, but it does redirect them to a warning screen, so this provides some protection. The edit script always takes out a lease.

It is impossible to fully lock a topic. Concurrent changes will be merged.

Since: TWiki::Plugins::VERSION 1.010 (31 Dec 2002)

saveTopic( $web, $topic, $meta, $text, $options ) -> $error

• $web - web for the topic
• $topic - topic name
• $meta - reference to TWiki::Meta object
• $text - text of the topic (without embedded meta-data!!!
• \%options - ref to hash of save options \%options may include:

  dontlog	don't log this change in twiki log
  comment	comment for save
  minor	True if this is a minor change, and is not to be notified

Since: TWiki::Plugins::VERSION 1.000 (29 Jul 2001)

For example,

my( $meta, $text ) = TWiki::Func::readTopic( $web, $topic )
$text =~ s/APPLE/ORANGE/g;
TWiki::Func::saveTopic( $web, $topic, $meta, $text, { comment => 'refruited' } );

Note: Plugins handlers ( e.g. beforeSaveHandler ) will be called as appropriate.

saveTopicText( $web, $topic, $text, $ignorePermissions, $dontNotify ) -> $oopsUrl

Save topic text, typically obtained by readTopicText(). Topic data usually includes meta data; the file attachment meta data is replaced by the meta data from the topic file if it exists.

• $web - Web name, e.g. 'Main', or empty
• $topic - Topic name, e.g. 'MyTopic', or "Main.MyTopic"
• $text - Topic text to save, assumed to include meta data
• $ignorePermissions - Set to "1" if checkAccessPermission() is already performed and OK
• $dontNotify - Set to "1" if not to notify users of the change

This method is a lot less efficient and much more dangerous than saveTopic.

Since: TWiki::Plugins::VERSION 1.010 (31 Dec 2002)

my $text = TWiki::Func::readTopicText( $web, $topic );

# check for oops URL in case of error:
if( $text =~ /^http.*?\/oops/ ) {
    TWiki::Func::redirectCgiQuery( $query, $text );
    return;
}
# do topic text manipulation like:
$text =~ s/old/new/g;
# do meta data manipulation like:
$text =~ s/(META\:FIELD.*?name\=\"TopicClassification\".*?value\=\")[^\"]*/$1BugResolved/;
$oopsUrl = TWiki::Func::saveTopicText( $web, $topic, $text ); # save topic text

moveTopic( $web, $topic, $newWeb, $newTopic )

• $web source web - required
• $topic source topic - required
• $newWeb dest web
• $newTopic dest topic

The destination topic must not already exist.

Rename a topic to the $TWiki::cfg{TrashWebName} to delete it.

Since: TWiki::Plugins::VERSION 1.1

use Error qw( :try );

try {
    moveTopic( "Work", "TokyoOffice", "Trash", "ClosedOffice" );
} catch Error::Simple with {
    my $e = shift;
    # see documentation on Error::Simple
} catch TWiki::AccessControlException with {
    my $e = shift;
    # see documentation on TWiki::AccessControlException
} otherwise {
    ...
};

getRevisionInfo($web, $topic, $rev, $attachment ) -> ( $date, $user, $rev, $comment )

• $web - Web name, optional, e.g. 'Main'
• $topic - Topic name, required, e.g. 'TokyoOffice'
• $rev - revsion number, or tag name (can be in the format 1.2, or just the minor number)
• $attachment -attachment filename

NOTE: if you are trying to get revision info for a topic, use $meta->getRevisionInfo instead if you can - it is significantly more efficient, and returns a user object that contains other user information.

NOTE: prior versions of TWiki may under some circumstances have returned the login name of the user rather than the wiki name; the code documentation was totally unclear, and we have been unable to establish the intent. However the wikiname is obviously more useful, so that is what is returned.

Since: TWiki::Plugins::VERSION 1.000 (29 Jul 2001)

getRevisionAtTime( $web, $topic, $time ) -> $rev

Get the revision number of a topic at a specific time.

• $web - web for topic
• $topic - topic
• $time - time (in epoch secs) for the rev

Since: TWiki::Plugins::VERSION 1.1

readTopic( $web, $topic, $rev ) -> ( $meta, $text )

Read topic text and meta data, regardless of access permissions.

• $web - Web name, required, e.g. 'Main'
• $topic - Topic name, required, e.g. 'TokyoOffice'
• $rev - revision to read (default latest)

$meta is a perl 'object' of class TWiki::Meta. This class is fully documented in the source code documentation shipped with the release, or can be inspected in the lib/TWiki/Meta.pm file.

This method ignores topic access permissions. You should be careful to use checkAccessPermissions to ensure the current user has read access to the topic.

Since: TWiki::Plugins::VERSION 1.000 (7 Dec 2002)

readTopicText( $web, $topic, $rev, $ignorePermissions ) -> $text

Read topic text, including meta data

• $web - Web name, e.g. 'Main', or empty
• $topic - Topic name, e.g. 'MyTopic', or "Main.MyTopic"
• $rev - Topic revision to read, optional. Specify the minor part of the revision, e.g. "5", not "1.5"; the top revision is returned if omitted or empty.
• $ignorePermissions - Set to "1" if checkAccessPermission() is already performed and OK; an oops URL is returned if user has no permission

This method is more efficient than readTopic, but returns meta-data embedded in the text. Plugins authors must be very careful to avoid damaging meta-data. You are recommended to use readTopic instead, which is a lot safer..

Since: TWiki::Plugins::VERSION 1.010 (31 Dec 2002)

attachmentExists( $web, $topic, $attachment ) -> $boolean

Test if attachment exists

• $web - Web name, optional, e.g. Main.
• $topic - Topic name, required, e.g. TokyoOffice, or Main.TokyoOffice
• $attachment - attachment name, e.g.=logo.gif=

readAttachment( $web, $topic, $name, $rev ) -> $data

• $web - web for topic
• $topic - topic
• $name - attachment name
• $rev - revision to read (default latest)

View permission on the topic is required for the read to be successful. Access control violations are flagged by a TWiki::AccessControlException. Permissions are checked for the current user.

my( $meta, $text ) = TWiki::Func::readTopic( $web, $topic );
my @attachments = $meta->find( 'FILEATTACHMENT' );
foreach my $a ( @attachments ) {
   try {
       my $data = TWiki::Func::readAttachment( $web, $topic, $a->{name} );
       ...
   } catch TWiki::AccessControlException with {
   };
}

Since: TWiki::Plugins::VERSION 1.1

saveAttachment( $web, $topic, $attachment, $opts )

• $web - web for topic
• $topic - topic to atach to
• $attachment - name of the attachment
• $opts - Ref to hash of options

Save an attachment to the store for a topic. On success, returns undef. If there is an error, an exception will be thrown.

    try {
        TWiki::Func::saveAttachment( $web, $topic, 'image.gif',
                                     { file => 'image.gif',
                                       comment => 'Picture of Health',
                                       hide => 1 } );
   } catch Error::Simple with {
      # see documentation on Error
   } otherwise {
      ...
   };

Since: TWiki::Plugins::VERSION 1.1

moveAttachment( $web, $topic, $attachment, $newWeb, $newTopic, $newAttachment )

• $web source web - required
• $topic source topic - required
• $attachment source attachment - required
• $newWeb dest web
• $newTopic dest topic
• $newAttachment dest attachment

The destination topic must already exist, but the destination attachment must not exist.

Rename an attachment to $TWiki::cfg{TrashWebName}.TrashAttament to delete it.

use Error qw( :try );

try {
   # move attachment between topics
   moveAttachment( "Countries", "Germany", "AlsaceLorraine.dat",
                     "Countries", "France" );
   # Note destination attachment name is defaulted to the same as source
} catch TWiki::AccessControlException with {

addToHEAD( $id, $header )

• $id - Unique ID to prevent the same HTML from being duplicated. Plugins should use a prefix to prevent name clashes (e.g EDITTABLEPLUGIN_JSCALENDAR)
• $header - the HTML to be added to the section. The HTML must be valid in a HEAD tag - no checks are performed.

All TWiki variables present in $header will be expanded before being inserted into the section.

Note that this is not the same as the HTTP header, which is modified through the Plugins modifyHeaderHandler.

Since: TWiki::Plugins::VERSION 1.1

Register a function to handle a simple variable. Handles both %VAR% and %VAR{...}%. Registered variables are treated the same as TWiki internal variables, and are expanded at the same time. This is a lot more efficient than using the commonTagsHandler.

• $var - The name of the variable, i.e. the 'MYVAR' part of %MYVAR%. The variable name must match /^[A-Z][A-Z0-9_]*$/ or it won't work.
• \&fn - Reference to the handler function.
• $syntax can be 'classic' (the default) or 'context-free'. 'classic' syntax is appropriate where you want the variable to support classic TWiki syntax i.e. to accept the standard %MYVAR{ "unnamed" param1="value1" param2="value2" }% syntax, as well as an unquoted default parameter, such as %MYVAR{unquoted parameter}%. If your variable will only use named parameters, you can use 'context-free' syntax, which supports a more relaxed syntax. For example, %MYVAR{param1=value1, value 2, param3="value 3", param4='value 5"}%

Since: TWiki::Plugins::VERSION 1.1

The variable handler function must be of the form:

sub handler(\%session, \%params, $topic, $web)

• \%session - a reference to the TWiki session object (may be ignored)
• \%params - a reference to a TWiki::Attrs object containing parameters. This can be used as a simple hash that maps parameter names to values, with _DEFAULT being the name for the default parameter.
• $topic - name of the topic in the query
• $web - name of the web in the query

sub initPlugin{
   TWiki::Func::registerTagHandler('EXEC', \&boo);
}

sub boo {
    my( $session, $params, $topic, $web ) = @_;
    my $cmd = $params->{_DEFAULT};

    return "NO COMMAND SPECIFIED" unless $cmd;

    my $result = `$cmd 2>&1`;
    return $params->{silent} ? '' : $result;
}
}

registerRESTHandler( $alias, \&fn, )

Adds a function to the dispatch table of the REST interface

• $alias - The name .
• \&fn - Reference to the function.

Since: TWiki::Plugins::VERSION 1.1

The handler function must be of the form:

sub handler(\%session)

• \%session - a reference to the TWiki session object (may be ignored)

From the REST interface, the name of the plugin must be used as the subject of the invokation.

Example

The EmptyPlugin has the following call in the initPlugin handler:

   TWiki::Func::registerRESTHandler('example', \&restExample);

This adds the restExample function to the REST dispatch table for the EmptyPlugin under the 'example' alias, and allows it to be invoked using the URL

http://server:port/bin/rest/EmptyPlugin/example

note that the URL

http://server:port/bin/rest/EmptyPlugin/restExample

(ie, with the name of the function instead of the alias) will not work.

Searching

searchInWebContent($searchString, $web, \@topics, \%options ) -> \%map

• $searchString - the search string, in egrep format
• $web - The web to search in
• \@topics - reference to a list of topics to search
• \%option - reference to an options hash

• type - if regex will perform a egrep-syntax RE search (default '')
• casesensitive - false to ignore case (defaulkt true)
• files_without_match - true to return files only (default false). If files_without_match is specified, it will return on the first match in each topic (i.e. it will return only one match per topic, and will not return matching lines).

The return value is a reference to a hash which maps each matching topic name to a list of the lines in that topic that matched the search, as would be returned by 'grep'.

To iterate over the returned topics use:

my $result = TWiki::Func::searchInWebContent( "Slimy Toad", $web, \@topics,
   { casesensitive => 0, files_without_match => 0 } );
foreach my $topic (keys %$result ) {
   foreach my $matching_line ( @{$result->{$topic}} ) {
      ...etc

Since: TWiki::Plugins::VERSION 1.1

Plugin-specific file handling

getWorkArea( $pluginName ) -> $directorypath

Gets a private directory for Plugin use. The Plugin is entirely responsible for managing this directory; TWiki will not read from it, or write to it.

The directory is guaranteed to exist, and to be writable by the webserver user. By default it will not be web accessible.

The directory and it's contents are permanent, so Plugins must be careful to keep their areas tidy.

Since: TWiki::Plugins::VERSION 1.1 (Dec 2005)

readFile( $filename ) -> $text

Read file, low level. Used for Plugin workarea.

• $filename - Full path name of file

NOTE: Use this function only for the Plugin workarea, not for topics and attachments. Use the appropriate functions to manipulate topics and attachments.

Since: TWiki::Plugins::VERSION 1.000 (07 Dec 2002)

saveFile( $filename, $text )

Save file, low level. Used for Plugin workarea.

• $filename - Full path name of file
• $text - Text to save

NOTE: Use this function only for the Plugin workarea, not for topics and attachments. Use the appropriate functions to manipulate topics and attachments.

Since: TWiki::Plugins::VERSION 1.000 (07 Dec 2002)

General Utilities

getRegularExpression( $name ) -> $expr

Retrieves a TWiki predefined regular expression or character class.

• $name - Name of the expression to retrieve. See notes below

Since: TWiki::Plugins::VERSION 1.020 (9 Feb 2004)

Note: TWiki internally precompiles several regular expressions to represent various string entities in an I18N-compatible manner. Plugins authors are encouraged to use these in matching where appropriate. The following are guaranteed to be present. Others may exist, but their use is unsupported and they may be removed in future TWiki versions.

In the table below, the expression marked type 'String' are intended for use within character classes (i.e. for use within square brackets inside a regular expression), for example:

   my $upper = TWiki::Func::getRegularExpression('upperAlpha');
   my $alpha = TWiki::Func::getRegularExpression('mixedAlpha');
   my $capitalized = qr/[$upper][$alpha]+/;

   my $webRE = TWiki::Func::getRegularExpression('webNameRegex');
   my $isWebName = ( $s =~ m/$webRE/ );

normalizeWebTopicName($web, $topic) -> ($web, $topic)

Parse a web and topic name, supplying defaults as appropriate.

• $web - Web name, identifying variable, or empty string
• $topic - Topic name, may be a web.topic string, required.

Since: TWiki::Plugins::VERSION 1.1

writeWarning( $text )

Log Warning that may require admin intervention to data/warning.txt

• $text - Text to write; timestamp gets added

Since: TWiki::Plugins::VERSION 1.020 (16 Feb 2004)

writeDebug( $text )

Log debug message to data/debug.txt

• $text - Text to write; timestamp gets added

Since: TWiki::Plugins::VERSION 1.020 (16 Feb 2004)

formatTime( $time, $format, $timezone ) -> $text

Format the time in seconds into the desired time string

• $time - Time in epoc seconds
• $format - Format type, optional. Default e.g. '31 Dec 2002 - 19:30'. Can be '$iso' (e.g. '2002-12-31T19:30Z'), '$rcs' (e.g. '2001/12/31 23:59:59', '$http' for HTTP header format (e.g. 'Thu, 23 Jul 1998 07:21:56 GMT'), or any string with tokens '$seconds, $minutes, $hours, $day, $wday, $month, $mo, $year, $ye, $tz' for seconds, minutes, hours, day of month, day of week, 3 letter month, 2 digit month, 4 digit year, 2 digit year, timezone string, respectively
• $timezone - either not defined (uses the displaytime setting), 'gmtime', or 'servertime'

Since: TWiki::Plugins::VERSION 1.020 (26 Feb 2004)

isValidWikiWord ( $text ) -> $boolean

Check for a valid WikiWord or WikiName

• $text - Word to test

Since: TWiki::Plugins::VERSION 1.100 (Dec 2005)

extractParameters($attr ) -> %params

Extract all parameters from a variable string and returns a hash of parameters

• $attr - Attribute string

Since: TWiki::Plugins::VERSION 1.025 (26 Aug 2004)

• Example:
  • Variable: %TEST{ 'nameless' name1="val1" name2="val2" }%
  • First extract text between {...} to get: 'nameless' name1="val1" name2="val2"
  • Then call this on the text:
    
• params = TWiki::Func::extractParameters( $text );=
  • The %params hash contains now:
    _DEFAULT => 'nameless'
name1 => "val1"
name2 => "val2"

extractNameValuePair( $attr, $name ) -> $value

Extract a named or unnamed value from a variable parameter string - Note: | Function TWiki::Func::extractParameters is more efficient for extracting several parameters

• $attr - Attribute string
• $name - Name, optional

Since: TWiki::Plugins::VERSION 1.000 (7 Dec 2002)

• Example:
  • Variable: %TEST{ 'nameless' name1="val1" name2="val2" }%
  • First extract text between {...} to get: 'nameless' name1="val1" name2="val2"
  • Then call this on the text:
    my $noname = TWiki::Func::extractNameValuePair( $text );
my $val1  = TWiki::Func::extractNameValuePair( $text, "name1" );
my $val2  = TWiki::Func::extractNameValuePair( $text, "name2" );

Deprecated functions

From time-to-time, the TWiki developers will add new functions to the interface (either to TWikiFuncDotPm, or new handlers). Sometimes these improvements mean that old functions have to be deprecated to keep the code manageable. When this happens, the deprecated functions will be supported in the interface for at least one more TWiki release, and probably longer, though this cannot be guaranteed.

Updated plugins may still need to define deprecated handlers for compatibility with old TWiki versions. In this case, the plugin package that defines old handlers can suppress the warnings in %FAILEDPLUGINS%.

This is done by defining a map from the handler name to the TWiki::Plugins version in which the handler was first deprecated. For example, if we need to define the endRenderingHandler for compatibility with TWiki::Plugins versions before 1.1, we would add this to the plugin:

package TWiki::Plugins::SinkPlugin;
use vars qw( %TWikiCompatibility );
$TWikiCompatibility{endRenderingHandler} = 1.1;

The following functions are retained for compatibility only. You should stop using them as soon as possible.

getScriptUrlPath( ) -> $path

Get script URL path

DEPRECATED since 1.1 - use getScriptUrl instead.

Return: $path URL path of TWiki scripts, e.g. "/cgi-bin"

WARNING: you are strongly recommended not to use this function, as the {ScriptUrlPaths} URL rewriting rules will not apply to urls generated using it.

Since: TWiki::Plugins::VERSION 1.000 (7 Dec 2002)

getPublicWebList( ) -> @webs

DEPRECATED since 1.1 - use getListOfWebs instead.

Get list of all public webs, e.g. all webs that do not have the NOSEARCHALL flag set in the WebPreferences

Return: @webs List of all public webs, e.g. ( 'Main',  'Know', 'TWiki' )

Since: TWiki::Plugins::VERSION 1.000 (07 Dec 2002)

formatGmTime( $time, $format ) -> $text

DEPRECATED since 1.1 - use formatTime instead.

Format the time to GM time

• $time - Time in epoc seconds
• $format - Format type, optional. Default e.g. '31 Dec 2002 - 19:30', can be 'iso' (e.g. '2002-12-31T19:30Z'), 'rcs' (e.g. '2001/12/31 23:59:59', 'http' for HTTP header format (e.g. 'Thu, 23 Jul 1998 07:21:56 GMT')

Since: TWiki::Plugins::VERSION 1.000 (7 Dec 2002)

getDataDir( ) -> $dir

DEPRECATED since 1.1 - use the content handling functions to manipulate topics instead

Get data directory (topic file root)

Return: $dir Data directory, e.g. '/twiki/data'

This function violates store encapsulation and is therefore deprecated.

Since: TWiki::Plugins::VERSION 1.000 (07 Dec 2002)

getPubDir( ) -> $dir

DEPRECATED since 1.1 - use the content handling functions to manipulateattachments instead

Get pub directory (file attachment root). Attachments are in $dir/Web/TopicName

Return: $dir Pub directory, e.g. '/htdocs/twiki/pub'

This function violates store encapsulation and is therefore deprecated.

Use readAttachment and saveAttachment instead.

Since: TWiki::Plugins::VERSION 1.000 (07 Dec 2002)

checkDependencies( $moduleName, $dependenciesRef ) -> $error

DEPRECATED since 1.1 - use TWiki:Plugins.BuildContrib and define DEPENDENCIES that can be statically evaluated at install time instead. It is a lot more efficient.

Since: TWiki::Plugins::VERSION 1.025 (01 Aug 2004)

TWiki CGI and Command Line Scripts

Programs on the TWiki server performing actions such as rendering, saving and renaming topics.

The TWiki scripts are located in the twiki/bin and twiki/tools directories. This topic describes the interfaces to some of those scripts. All scripts in the twiki/bin directory can be called from the CGI (Common Gateway Interface) environment or from the command line. The scripts in the twiki/tools directory can only be called from the command line.

CGI Scripts

General Information

CGI environment

Command-line

Parameters are passed on the command line using '-name' - for example,

$ cd /usr/local/twiki/bin
$ save -topic MyWeb.MyTopic -user admin -action save -text "New text of the topic"

Common parameters

attach

changes

The changes script can receive one parameter:

The main difference between invoking this script and using WebChanges is that WebChanges is based on a %SEARCH%, while this script reads the changes file in each web, making it much faster.

NOTE: The result from changes script and the topic WebChanges can be different, if the changes file is deleted from a web. In particular, in new installations the changes script will return no results while the WebChanges topic will.

configure

edit

Form field values are passed in parameters named 'field' - for example, if I have a field Status the parameter name is Status.

1. The first sequence of ten or more X characters in the topic name will be converted on save to a number such that the resulting topic name is unique in the target web.

NOTE: most skins support the definition of EDIT_SKIN, which is used as the value of the cover parameter in edit URLs. This allows you to override the default edit skin on a web, topic or user basis.

login

logon

manage

action=createweb

action=deleteUserAccount

action=editSettings

action=bulkRegister

action=saveSettings

oops

oops templates are used with the oops script to generate system messages. This is done to make internationalisation or other local customisations simple.

The oops script supports the following parameters:

passwd

action=changePassword

preview

rdiff

• add a {word} render style

register

rename

resetpasswd

This is used by BulkResetPassword and ResetPassword. Only users belonging to the TWikiAdminGroup can provide a list of LoginNames, non-admins can only provide a single LoginName.

BulkRegistration provides the means to create multiple accounts but it does not announce those accounts to the users who own them. BulkResetPassword is used to assign the passwords, the Introduction is used to explain why they are receiving the mail.

rest

The rest script itself uses one parameter:

Any additional parameters are passed directly to the function (i.e: The function can get any other parameter using the CGI $query object)

Invocation Examples

The rest script assumes that it will be called with URL in the form:

http://my.host/bin/rest/<subject>/<verb>

where <subject> must be the WikiWord name of one of the installed TWikiPlugins, and the <verb> is the alias for the function registered using the registerRESTHandler. The <subject> and <verb> are then used to lookup and call the registered function.

Functions outside the Plugins also can be registered, but please consider the security implications of allowing URL access, as functions can sidestep TWiki Authentication & Authorisation settings.

<subject> and <verb> are checked for illegal characters exactly in the same way as the web and topic names.

As an example, the EmptyPlugin has registered a function to be used with the rest script under the subject EmptyPlugin and the verb example. Click below to see the rest script in action (run as TWikiGuest).

Call the Plugin

You can also call the function from the command line, but this will be run as the TWikiAdminGroup (as it is assumed that shell access is secure) - eg:

./rest EmptyPlugin.example

Note that for calls to Plugins, they must be enabled in configure.

save

Any errors will cause a redirect to an oops page.

The parameters are interpreted in according to the following rules.

1. The first sequence of ten or more X characters in the topic name will be converted to a number such that the resulting topic name is unique in the target web.
2. When the action is save, checkpoint, quietsave, or preview:
   1. The new text is taken from the text parameter, if it is defined,
      • otherwise it is taken from the templatetopic, if it is defined,
      • otherwise it is taken from the previous version of the topic, if any,
   2. The name of the new form is taken from the formtemplate, if defined
      • otherwise it is taken from the templatetopic, if defined,
      • otherwise it is taken from the previous version of the topic, if any,
      • otherwise no form is attached.
   3. The value for each field in the form is taken from the query, if it is defined
      • otherwise it is taken from the templatetopic, if defined,
      • otherwise it is taken from the previous version of the topic, if any,
      • otherwise it defaults to the empty string.

Merging is only enabled if the topic text comes from text and originalrev is > 0 and is not the same as the revision number of the most recent revision. If merging is enabled both the topic and the meta-data are merged.

Form field values are passed in parameters named 'field' - for example, if I have a field Status the parameter name is Status.

search

statistics

twiki

upload

You can use a tool like curl to upload files from the command line using this script.

view

For historical reasons, the view script has a special interpretation of the text skin. In earlier TWiki versions the skin=text parameter was used like this: http://.../view/MyWeb/MyTopic?skin=text&contenttype=text/plain&raw=on which shows the topic as plain text; useful for those who want to download plain text for the topic. Using skin=text this way is DEPRECATED, use raw=text instead.

viewfile

Command Line Scripts

geturl.pl

• Usage: geturl <host> <path> [<port> [<header>]]
• Example: geturl some.domain /some/dir/file.html 80
• Will get: http://some.domain:80/some/dir/file.html

rewriteshebang.pl

tick_twiki.pl

It is intended to be run as a cron job or a scheduled task once a week. Example crontab entry:
0 0 * * 0 cd /usr/twiki/bin && perl ../tools/tick_twiki.pl

Note: The script has to be run by a user who can write files created by the webserver user.
