Skin template markup language

As described on the Skins page, skin templates are regular XHTML files with special tags which are then replaced by the content according to their meaning.

Tags

The template engine of Roundcube supports the following tags. All tags are written in common HTML syntax and require certain attributes. Regular HTML attributes are also accepted and will be added to the final HTML output of the according tag.

roundcube:include

Includes (and processes) the referenced file. Similar to PHPs include() the content of the included file will be parsed by the template engine and then placed where this tag is placed.

Attributes:

  • file: Path to the file to be included starting with /
  • condition: Boolean condition to be fulfilled

Example:

<roundcube:include file="/includes/head.html" />

roundcube:var

Returns the content of the specified environment variable. See Environment variables for possible values.

Attributes:

  • name: The variable name

Example:

<roundcube:var name="env:task" />

roundcube:exp

Evaluates the given expression and returns the resulting content. The syntax of the expressions is actually PHP code but can contain variables as described in Environment variables.

Attributes:

  • expression: The expression to evaluate

Examples:

<roundcube:exp expression="!empty(cookie:mailviewsplitter) ? cookie:mailviewsplitter-5 : 245" />
<roundcube:exp expression="browser:ie ? 'width:400px' : '380px'" />

roundcube:label

Gets a localized text with the given name. Also allows to define localized texts for various languages and 'register' them under the given name.

Attributes:

  • name: The label name
  • condition: Boolean condition to be fulfilled
  • quoting: How to escape special characters: html,javascript,no; default is html
  • noshow: Only register the localized text under the given name but do not print it
  • <lang-code>: Defines the text value for the given language code

Examples:

<roundcube:label name="errortitle" quoting="javascript" />

<!-- register label -->
<roundcube:label name="my.label" en_US="My Label" de_DE="Mein Text" noshow="true" />

<!-- print custom label -->
<roundcube:label name="my.label" />

roundcube:button

Creates a button for a specific command of the Roundcube client. A button is also registered in the UI manager and is automatically enabled and disabled according to the current state of the application.

Attributes:

  • type: The type of the button. Possible values are link|input|image
  • command: The application command this button triggers
  • prop: Additional argument of the triggered command
  • label: Localized text content of "link" buttons
  • title: The common HTML title attribute. Use the name of a localized label
  • content: The actual content of the generated HTML element
  • class: CSS class(es) for the disabled state of the button
  • classAct: CSS class(es) for the enabled state
  • classSel: CSS class(es) applied when the button is pressed
  • imagePas: Image file for the disabled state
  • imageAct: Image file for the enabled state
  • imageSel: Image displayed when the button is pressed
  • condition: Boolean condition to be fulfilled

Types:

  • link: Creates a regular <a></a> tag
  • input: Creates a form button
  • image: Creates a button using the given image

Examples:

<roundcube:button command="mark" prop="read" label="markread" class="rlink" classAct="rlink active" />
<roundcube:button command="save" type="input" class="button mainaction" label="save" />
<roundcube:button command="add" imageAct="/images/btn_add_act.png" imagePas="/images/btn_add_pas.png" width="32" height="32" title="newcontact" />

roundcube:container

This tag defines a container where plugins can add their stuff. HTML content will be added at this tags position by the template engine and it also specifies the ID of a DOM element where more content can be added client side.

Attributes:

  • name: The name of the container
  • id: ID of the HTML element which actually represents this container

Example:

<div id="thetaskbar">
...
<roundcube:container name="taskbar" id="thetaskbar" />
</div>

roundcube:object

Dynamic content which is created by the application is put into the template with this tag. An object is identified by the name attribute and can require further attributes according to the object type as well as regular HTML attributes which are just passed through. The section Content objects describes all available objects and their attributes.

Please note that most objects are only available in certain steps/tempaltes. An object tag will be ignored and replaced by an empty string if it's not available.

Attributes:

  • name: The object to put here
  • condition: Boolean condition to be fulfilled
  • object-specific attributes

Examples:

<roundcube:object name="messageContentFrame" id="messagecontframe" width="100%" height="100%" src="/watermark.html" />
<roundcube:object name="messageCountDisplay" style="padding:0.5em; float:right" />

(since 1.5)

Note: To use dynamic values for object-specific attributes the attribute name can be proceeded by a colon (:).

Examples:

<roundcube:object name="messages" :optionsmenuicon="!in_array('list_cols', (array)config:dont_override)" />

roundcube:if/elseif/else/endif

These tags allow you the include or exclude certain parts of the template if a given Conditional expressions evaluates to true.

Attributes:

  • condition: Boolean condition to be fulfilled

Example:

<roundcube:if condition="count(env:address_sources) &gt; 1" />
  ...
<roundcube:else />
  ...
<roundcube:endif />

Environment variables

Certain variables from the running PHP script are available to the templates too. They're mainly used to build conditional expressions or to be written to the final output using the roundcube:expression tag. There are several "sources" or environments where values can be retrieved from. A variable selector consists of the environment name followed by a colon and the field name:

env:action

The following environments are available:

session:

This selector gives access to session variables. For example:

session:username

config:

All configuration values as set in config/main.inc.php can be accessed using this selector. It is also possible to set a default value which is used in case the config parameter is not set. This is done by adding another colon followed by the default value:

config:sent_mbox:Sent

env:

This selector gives access to state variables which define the current action and all its state. The most important ones are:

env:task
env:action
env:quota
env:address_sources

Env variables are very specific to tasks and actions. See the source code for more vars.

cookie:

This selectors provides access to the cookies submitted by the client. This includes cookies which were set server-side as well as cookies set by the skin itself using javascript.

request:

Similar to the cookie: selector this one provides access to values of the current request submitted either by POST or GET.

browser:

The Roundcube backend provides a browser detection class which analyzes the user agent string submitted by the client and extracts certain values and boolean properties. The browser selector contains the following properties:

  • ie True if Internet Explorer
  • mz True if Mozilla Firefox or other Mozilla derivate
  • ns True if Netscape browser
  • opera True for Opera browsers
  • khtml True for KHTML-based browsers
  • safari Alias for KHTML
  • chrome True for Google Chrome browser
  • ver The version number according to the browser type
  • lang The user agent language (2 chars)
  • win True for Windows operating system
  • mac True for Mac OS
  • linux True for any Linux OS
  • unix True for other Unix systems

Conditional expressions

If a tag has the condition attribute it will only create output if the conditional expression within this attribute evaluates to true. These expressions consist of environment variables, boolean operators and also PHP functions. They should either evaluate to true or false, numeric values > 0 are considered as true.

Examples:

env:task == 'mail && !empty(cookie:mailviewsplitter)
count(env:address_sources) <= 1
config:identities_level:0 < 2
browser:safari || browser.opera
