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.

TWiki CGI and Command Line Scripts

Line: 14 to 14

CGI environment

In the CGI environment parameters are passed to the scripts via the URL and URL parameters. Environment variables are also used to determine the user performing the action. If the environment is not set up, the default TWiki user is used (usually guest).

Command-line

Changed:

<
< You must be cd'd to the twiki/bin directory to run the scripts from the command line. To avoid issues with file permissions, run the scripts as the web server user such as nobody or www.

>
> You must be have the twiki/bin directory on the perl path to run the scripts from the command line. To avoid issues with file permissions, run the scripts as the web server user such as nobody or www.

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"

Changed:

<
< All parameters require a value.

>
> All parameters require a value, even if that is the empty string.

Common parameters

All the scripts accept a number of common parameters. The first two components of the URL after the script name are taken as the web and the topic, respectively. Standard URL parameters are:

Line: 51 to 51

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`

Changed:

<
< configure is the browser script used for inspection and configuration of the TWiki configuration. None of the parameters to this script are useable for any purpose except configure.

>
> configure is the browser script used for inspection and configuration of the TWiki configuration. None of the parameters to this script are useable for any purpose except configure. See configure.

`edit`

The edit scipt understands the following parameters, typically supplied by HTML input fields:

Line: 67 to 67

`contenttype`	Optional parameter that defines the application type to write into the CGI header. Defaults to `text/html`. May be used to invoke alternative client applications
`anyname`	Any parameter can passed to the new topic; if the template topic contains `%URLPARAM{"anyname"}%`, it will be replaced by its value
`breaklock`	If set, any lease conflicts will be ignored, and the edit will proceed even if someone is already editing the topic.

Added:

>
>

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

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.

Line: 188 to 189

`rest`

Changed:

<
<

This REST (Representational State Transfer) script can be invoked via http in a similar way as the view script (see Invocation Examples, below) to execute a function that is associated to a "subject" and a "verb" (see below). It'll print the result directly to the stream unless the endPoint parameter is specified, in which case the control is redirected to the given topic.

The rest script itself uses one parameter:

The rest script will print the result directly to the browser unless the endPoint parameter is specified, in which case it will output a redirect to the given topic.

Added:

The rest script supports the following parameters:

`username`	If `TemplateLogin`, or a similar login manager not embedded in the web server, is used, then you need to pass a username and password to the server. The `username` and `password` parameters are used for this purpose.
`password`	See `username`
`topic`	If defined as the full name (including web) of a topic, then when the script starts up plugins will be passed this as the "current" topic. If not defined, then %USERWEB%.WebHome will be passed to plugins.

endPoint Where to redirect the response once the request is served, in the form "Web.Topic"

Changed:

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

>
>

The function is free to use any other query parameters for its own purposes.

The rest script should always require authentication in any TWiki that has logins. Otherwise there is a risk of opening up major security holes. So make sure you add it to the list of authenticated scripts if you are using ApacheLogin.

Invocation Examples

Line: 202 to 207

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

Changed:

<
<

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.

>
> 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 TWiki::Func::registerRESTHandler method. The <subject> and <verb> are then used to lookup and call the registered function.

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

Line: 212 to 215

Call the Plugin

Changed:

<
<

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.

>
> Note that for Plugins to register REST handlers, they must be enabled in configure.

TWiki CGI and Command Line Scripts

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

CGI Scripts

Details on CGI scripts located in the twiki/bin directory.

General Information

CGI environment

Command-line

You must be cd'd to the twiki/bin directory to run the scripts from the command line. To avoid issues with file permissions, run the scripts as the web server user such as nobody or www.

Parameters are passed using '-name' - for example,

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

All parameters require a value.

Common parameters

All the scripts accept a number of common parameters. The first two components of the URL after the script name are taken as the web and the topic, respectively. Standard URL parameters are:

Parameter	Description	Default
`topic`	If this is set to a URL, TWiki will immediately redirect to that URL. Otherwise it overrides the URL and is taken as the topic name (you can pass Web.TopicName)
`user`	Command-line only; set the name of the user performing the action. Note: this usage is inherently insecure, as it bypasses webserver login constraints. For this reason only authorised users should be allowed to execute scripts from the command line.
`skin`	Overrides the default skin path (see TWikiSkins)
`cover`	Specifies temporary skin path to prepend to the skin path for this script only (see TWikiSkins)

`attach`

Despite the name, this script doesn't actually attach a file to a topic - for that, use upload. This script is part of the transactions sequence executed when a file is uploaded from the browser. it just generates the "new attachment" page for a topic.

Parameter	Description	Default
`filename`	Name of existing attachment (if provided, this is a "manage attachment" action)	none (in which case this is a "new attachment" action)

`changes`

Shows all the changes in the given web.

The changes script can receive one parameter:

Parameter	Description	Default
`minor`	If 0, show only major changes. If 1, show all the changes (both minor and major)	0

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.

`configure`

configure is the browser script used for inspection and configuration of the TWiki configuration. None of the parameters to this script are useable for any purpose except configure.

`edit`

The edit scipt understands the following parameters, typically supplied by HTML input fields:

Parameter	Description	Default
`action`	Optional. Use the editaction template instead of the standard edit. If action=text, then hide the form. If action=form hide the normal text area and only edit the form.
`onlynewtopic`	If set, error if topic already exists
`onlywikiname`	If set, error if topic name is not a WikiWord
`templatetopic`	The name of the template topic, copied to get the initial content
`text`	Initial text for the topic
`topicparent`	The parent topic
`formtemplate`	Name of the form to instantiate in the topic. Overrides the form set in the `templatetopic` if defined.
`contenttype`	Optional parameter that defines the application type to write into the CGI header. Defaults to `text/html`. May be used to invoke alternative client applications
`anyname`	Any parameter can passed to the new topic; if the template topic contains `%URLPARAM{"anyname"}%`, it will be replaced by its value
`breaklock`	If set, any lease conflicts will be ignored, and the edit will proceed even if someone is already editing the topic.

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

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`

Used for logging in when TWiki login is being used (e.g TemplateLoginManager).

Parameter	Description	Default
`origurl`	URL that was being accessed when an access violation occurred. the login process will redirect to this URL if it is successful	none
`username`	username of user logging in	none
`password`	password of user logging in	none

`logon`

Used for logging in when Web Server authentication is being used (e.g. ApacheLoginManager). The script does nothing; it is purely a placeholder for triggering the login process. The webserver will be set up to require a valid user to access this script, thus triggering the webserver login process.

`manage`

Performs a range of management functions.

Parameter	Description	Default
`action`	One of `createweb`, `deleteUserAccount`, `editSettings` or `saveSettings`	none

`action=createweb`

Parameter	Description	Default
`newweb`	Name of the new web	''
`baseweb`	Name of the web to copy to create the new web	''
`webbgcolor`	value for WEBBGCOLOR	''
`sitemapwhat`	Value for SITEMAPWHAT	''
`sitemapuseto`	Value for SITEMAPUSETO	''
`nosearchall`	Value for NOSEARCHALL	''

`action=deleteUserAccount`

Unregisters (removes) the currently logged-in user.

Parameter	Description	Default
`password`	Users' password	none

`action=editSettings`

No parameters

`action=bulkRegister`

See BulkRegistration.

Parameter	Description	Default
`OverwriteHomeTopics`	Whether to overwrite existing home topics or not	false
`EmailUsersWithDetails`	Whether to mail registered users or not	false
`LogTopic`	Topic to save the log in	Same as topic name, with 'Result' appended.

`action=saveSettings`

Parameter	Description	Default
`text`	Text of the topic	''
`originalrev`	Revision that the edit started on	Most recent revision

All other parameters may be interpreted as form fields, depending on the current form definition in the topic.

`oops`

This script is mainly used for rendering pages containing error messages, though it is also used for some functional actions such as manage pages (move topic etc).

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:

Parameter	Description	Default
`template`	Name of the template file to display
`def`	Optional, can be set to the name of a single definition within `template`. This definition will be instantiated in the `template` wherever `%INSTANTIATE%` is seen. This lets you use a single template file for many messages. For an example, see `oopsmanagebad.tmpl`.
`paramN`	Where N is an integer from 1 upwards. These values will be substituted into `template` for `%PARAM1%` etc.

`passwd`

Parameter	Description <-- -->	Default
`action`	one of `changePassword` or `resetPassword`	none

Other parameters as described under manage, action=changePassword.

`action=changePassword`

Parameter	Description	Default
`username`	Username
`oldpassword`	Existing password (plain text)
`password`	New password (plain text)
`passwordA`	New password confirmation (plain text)
`TopicName`	?

`preview`

This script is deprecated. Its functions are covered by the save script.

`rdiff`

Renders the differences between version of a TWiki topic

Parameter	Description	Default
rev1	the higher revision
rev2	the lower revision
render	the rendering style {sequential, sidebyside, raw, debug}	DIFFRENDERSTYLE, `sequential`
type	history, diff, last} history diff, version to version, last version to previous	`diff`
context	number of lines of context

TODO:

add a {word} render style

`register`

Parameter	Description	Default
`action`	`register` or `verify` or `resetPassword` or `approve`

`rename`

Used for renaming topics.

Parameter	Description	Default
`skin`	skin(s) to use
`newweb`	new web name
`newtopic`	new topic name
`breaklock`
`attachment`
`confirm`	if defined, requires a second level of confirmation
`currentwebonly`	if defined, searches current web only for links to this topic
`nonwikiword`	if defined, a non-wikiword is acceptable for the new topic name

`resetpasswd`

Reset the password for a single or multiple users

Parameter	Description	Default
`LoginName`	list of usernames to reset	none - error if not set
`Introduction`	message to be sent alongside the reset, most often used to announce to the user that they have been given an account.	''

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.

`rest`

The rest script itself uses one parameter:

endPoint Where to redirect the response once the request is served, in the form "Web.Topic"

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>

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`

The save script performs a range of save-related functions, as selected by the action parameter.

Parameter	Description	Default
`action_save=1`	default; save, return to view, dontnotify is OFF
`action_quietsave=1`	save, and return to view, `dontnotify` is ON
`action_checkpoint`	save and redirect to the edit script, `dontnotify` is ON
`action_cancel`	exit without save, return to view
`action_preview`	preview edited text
`action_addform`	Redirect to the "change form" page.
`action_replaceform...`	Redirect to the "change form" page.
`action_delRev`	Administrators only delete the most recent revision of the topic - all other parameters are ignored. You have to be a member of TWikiAdminGroup to use this, and not all store implementations will support it.
`action_repRev`	Administrators only replace the text of the most recent revision of the topic with the text in the `text` parameter. `text` must included embedded meta-data tags. All other parameters are ignored. You have to be a member of TWikiAdminGroup to use this, and not all store implementations will support it.
`onlynewtopic`	If set, error if topic already exists
`onlywikiname`	If set, error if topic name is not a WikiWord
`dontnotify`	if defined, suppress change notification
`templatetopic`	Name of a topic to use as a template for the text and form
`text`	New text of the topic
`forcenewrevision`	if set, forces a revision even if TWiki thinks one isn't needed
`topicparent`	If 'none' remove any current topic parent. If the name of a topic, set the topic parent to this.
`formtemplate`	if defined, use the named template for the form
`editaction`	When action is `checkpoint`, `add form` or `replace form...`, this is used as the `action` parameter to the `edit` script that is redirected to after the save is complete.
`originalrev`	Revision on which the edit started.

Any errors will cause a redirect to an oops page.

The parameters are interpreted in according to the following rules.

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.
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`

CGI gateway to the %SEARCH% functionality driven by the following CGI parameters:

`multiple="on"`	Multiple hits per topic. Each hit can be formatted. The last token is used in case of a regular expression ";" and search	Only one hit per topic
`nofinalnewline="on"`	If `on`, the search variable does not end in a line by itself. Any text continuing immediately after the search tag on the same line will be rendered as part of the table generated by the search, if appropriate.	`off`
`separator=", "`	Line separator between hits	Newline `"$n"`

`statistics`

Refresh the WebStatistics topics in range of webs.

Parameter	Description	Default
`webs`	list of webs to run stats on	none

`twiki`

Single-script interface to the functionality of all the other scripts. Experimental, not for production use. Read the code if you want to know more.

`upload`

Uploads an attachment to a topic. The HTTP request is expected to be in multipart/form-data format.

Parameter	Description	Default
`hidefile`	if defined, will not show file in attachment table
`filepath`	local (client) path name of the file being uploaded. This is used to look up the data for the file in the HTTP query.
`filename`	deprecated, do not use
`filecomment`	Comment to associate with file in attachment table
`createlink`	if defined, will create a link to file at end of topic
`changeproperties`	if defined, this is a property change operation only - no file will be uploaded.	null

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

`view`

Used for viewing topics.

Parameter	Description	Default
`raw=on`	Shows the text of the topic in a scrollable textarea
`raw=debug`	As `raw=on`, but also shows the metadata (forms etc) associated with the topic.
`raw=text`	Shows only the source of the topic, as plain text (Content-type: text/plain). Only shows the body text, not the form or other meta-data.
`raw=all`	Shows only the source of the topic, as plain text (Content-type: text/plain), with embedded meta-data. This may be useful if you want to extract the source of a topic to a local file on disc.
`contenttype`	Allows you to specify a different Content-Type: (e.g. `contenttype=text/plain`)
`rev`	Revision to view (e.g. `rev=45`)
`template`	Allows you to specify a different skin template, overriding the 'view' template the view script would normally use. The default template is `view`. For example, you could specify /twiki/bin/view/TWiki/TWikiScripts?template=edit. This is mainly useful when you have specialised templates for a TWiki Application.

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`

Used for viewing attachments. Normally, a site will publish the attachments (pub) directory using a URL. However if it contains sensitive information, you will want to protect attachments using TWikiAccessControls. In this case, you can use the viewfile script to give access to attachments while still checking access controls.

Parameter	Description	Default
`filename`	name of attachment
`rev`	Revision to view

Command Line Scripts

Details on command line scripts located in the twiki/tools directory.

`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`

Simple script to rewrite the #!/usr/bin/perl shebang lines specific to your local Perl installation. It will rewrite the first line of all your TWiki cgi scripts so they use a different shebang line. Use it if your perl is in a non-standard location, or you want to use a different interpreter (such as 'speedy').

`tick_twiki.pl`

This script executes a number of non-essential regular administration tasks that will help keep your TWiki healthy and happy, such as removing expired sessions and lease files.

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.
