XWiki Syntaxes

Last modified by Vincent Massol on 2013/03/22 14:43

Starting with XWiki Enterprise version 1.7 we've introduced a new wiki syntax. We've named the old syntax the XWiki Syntax 1.0 and the new syntax was logically called the XWiki Syntax 2.0. The main reasons for introducing the new syntax were:

  • Fix the limitations and ambiguities of the XWiki Syntax 1.0 (which was inspired by both Radeox - the underlying rendering engine - and TWiki).
    • Not optimal symbols. For example the symbol for bold was single stars. This was causing trouble when users were entering text containing stars since that text was mistakenly considered to be bold when it wasn't. Hence we've rationalized the syntax by using at least double characters everywhere. 
    • Ambiguities. For example there was an ambiguity between a bold item starting a line and a bulletted list. Resolving the ambiguities was required in order to rewrite the WYSIWYG editor so that it could be deterministic.
  • Be closer to the Creole 1.0 syntax which is becoming a standard for wiki syntax. In addition the Creole community has taken the time to analyze all the existing wiki syntaxes before deciding on symbols. The choices made are thus very good.

Since the introduction of XWiki Syntax 2.0 a few shortcomings of this syntax have been found. To fix these a new, as of now experimental, XWiki Syntax 2.1 was introduced in XWiki Enterprise version 3.0. Some reason for the development of this new syntax are:

  • Homogenize the link and image syntax for better clarity, consistency and extensibility.
  • Added ability to display icons,  to link to files using the UNC notation and to link to relative URLs.
Since XWiki Syntax 2.1 is based on XWiki Syntax 2.0 all syntax from XWiki Syntax 2.0 is valid unless the 2.1 specifications suggest differently.

In addition to these XWiki-specific syntaxes we've also changed our underlying rendering engine in XWiki Enterprise version 1.7 (was Radeox previously) in favor of our own engine which is superset wrapper around Wikimodel and Doxia (and possibly others in the future). This has allowed us to provide other syntaxes in the wiki: MediaWiki, Confluence, JSPWiki, Creole, TWiki and more.

General Remarks

XWiki Syntax 2.0 corrects some errors or ambiguous syntax entered by the user as shown in the examples in the table below.

Text Formatting

New in XWiki Syntax 2.0 over XWiki Syntax 1.0:

  • Spaces are allowed just after the syntax symbols (for example in XWiki Syntax 1.0, this was not possible: * bold *).
  • Use double symbols when there was only a single symbol in XWiki Syntax 1.0 so that it's less likely that the user will mistakenly use them in text.
  • Ability to span several lines (wasn't possible in XWiki Syntax 1.0).

XWiki Syntax 2.0 Image Specification

The part in ( ) is required, while the parts in { } are optional.

The full format of an image is either image: (reference) or [[image: (reference) {||parameters}]]

  • image: A required string identifying the resource as image.
  • reference: The reference to the image that shall be displayed in one of the following forms:
    • URL: Any URL to an image in the form of http://path/imageName. Example: http://domain.org/path/img.png
    • Attachment reference in the form {{{wikiName:} space.} page@} (imageName)
      • wikiName: An optional string containing the name of a virtual wiki. The image reference will point to an image attached to a page inside that virtual wiki. Example: mywiki
      • space: An optional wiki Space name. If no space is specified the current space is used. Example: Main
      • page: An optional string containing the name of the wiki page to which the referenced image is attached. Example: WebHome
      • imageName: A required string containing the name of the image attached to a page as it is stored in the wiki.
  • parameters: An optional list of space-separated parameters passed to the image. Example: width="800" height="600" alt="img.png" title="My nice image"
    • HTML attributes: All attributes defined by the HTML standard will be added to the rendered HTML <img> tag.
      • style: CSS style information that should be applied to the image. Examples: style="float:right;height:50" (image on right side, height 50 px), style="style="display:block;margin-left:auto;margin-right:auto;width:80%" (image centered, width 80% of block width), style="vertical-align:bottom" (text starts at bottom of picture)
      • height: A parameter that defines the height of the displayed image. The value should be presented either in pixel (example: height="80") or in pixel related to the height of the block containing the image (example: height="40%").
      • width: A parameter that defines the width of the displayed image. The value should be presented either in pixel (example: width="80") or in pixel related to the width of the block containing the image (example: width="40%").
      • title: A parameter that defines the title the displayed image which will be visible when hovering the mouse trigger over the image, for instance. Example: title="My nice image"
      • alt: A parameter that defines which text should be displayed if the browser is not able to display the image. Since this is a required HTML attribute XWiki will use the file name instead if the alt parameter is not defined. Example: alt="img.png"
      • More: A more in depth explanation on the HTML <img> tag including more attributes can be reviewed on w3.org.

      • space: An optional wiki Space name. If no space is specified the current space is used. Example: Main
      • page: An optional string containing the name of the wiki page to which the referenced image is attached. Example: WebHome
      • imageName: A required string containing the name of the image attached to a page as it is stored in the wiki.
    • Icon reference in the form (icon:) (iconName). Example: icon:accept
      • icon: A required string identifying the image reference as an icon from the XWiki Icon Set.
      • iconName: A required string identifying the icon referenced. Example: accept
  • parameters: An optional list of space-separated parameters passed to the image. Example: width="800" height="600" alt="img.png" title="My nice image"
    • HTML attributes: All attributes defined by the HTML standard will be added to the rendered HTML <img> tag.
      • style: CSS style information that should be applied to the image. Examples: style="float:right;height:50" (image on right side, height 50 px), style="style="display:block;margin-left:auto;margin-right:auto;width:80%" (image centered, width 80% of block width), style="vertical-align:bottom" (text starts at bottom of picture)
      • height: A parameter that defines the height of the displayed image. The value should be presented either in pixel (example: height="80") or in pixel related to the height of the block containing the image (example: height="40%").
      • width: A parameter that defines the width of the displayed image. The value should be presented either in pixel (example: width="80") or in pixel related to the width of the block containing the image (example: width="40%").
      • title: A parameter that defines the title the displayed image which will be visible when hovering the mouse trigger over the image, for instance. Example: title="My nice image"
      • alt: A parameter that defines which text should be displayed if the browser is not able to display the image. Since this is a required HTML attribute XWiki will use the file name instead if the alt parameter is not defined. Example: alt="img.png"
      • More: A more in depth explanation on the HTML <img> tag including more attributes can be reviewed on w3.org.
    • queryString: Allows queries to be passed to the server when creating the download link for the referenced image. Example: queryString="width=100&height=800&keepAspectRatio=true" (keepAspectRatio=true will fail if the width and height parameters are specified in addition to queryString!)

Verbatim

Allow to enter content that will not be formatted (in other words the XWiki Syntax will not be taken into account).

In XWiki Syntax 1.0 the Pre macro only preserves XWiki Syntax and Radeox macros. However HTML snippets and Groovy/Velocity scripts are still executed.

Groups

Groups can be used to insert another document inline directly into the current document. This allows for example to insert complex elements inside a list item or inside a table cell. Groups are delimited by the following syntactic elements: (((...))). One Group can contain another Group and there is no limit of imbrication.

Macros

There are 2 kinds of macros in XWiki Syntax 1.0:

  • Velocity macros (called using the #macroname(param1 ... paramN) syntax)
  • Radeox macros (called using the {macroname:param1=value1|...|paramN=valueN} syntax)

There are also 2 kinds of macros in XWiki Syntax 2.0:

  • Velocity macros (called using the #macroname(param1 ... paramN) syntax inside the Velocity Macro)
  • XWiki macros (called using the {{macroname param1="value1" ... paramN="valueN"}} syntax)
The Radeox macros cannot be used in XWiki Syntax 2.0. Thus they have been rewritten as XWiki macros.
For the full list of available macros check the Extensions wiki.

Velocity Macro
#info("Some text")
{{info}}
Some text
{{/info}}
Radeox Macro/XWiki Macro
{code:java}
java content
{code}
{{code language="java"}}
java content
{{/code}}

HTML

In XWiki Syntax 2.0 HTML or XHTML must be entered by using the HTML macro whereas in XWiki Syntax 1.0 it's possible to enter HTML directly in the text.
XWiki Syntax 1.0XWiki Syntax 2.0Result
<b>bold</b>{{html}}<b>bold</b>{{/html}}bold
In XWiki Syntax 2.0, by default the HTML macro does not understands XWiki Syntax (other macros included since it's XWiki Syntax too). To enable it, use {{html wiki="true"}}.

Velocity/Groovy Scripts

In XWiki Syntax 1.0 it was possible to enter Velocity scripts anywhere directly in the page. This lead to issues for example when the user was involuntarily entering Velocity content. It was also performance hungry for pages not requiring Velocity content. There were several other technical limitations. Thus in XWiki Syntax 2.0 Velocity scripts must be entered using the velocity macro. Same goes for entering Groovy scripts.
FeatureXWiki Syntax 1.0XWiki Syntax 2.0
Velocity script
#set ($var = "whatever")
{{velocity}}
#set ($var = "whatever")
{{/velocity}}
Groovy script
<%
def var = "whatever"
%>
{{groovy}}
def var = "whatever"
{{/groovy}}

Parameters

With XWiki Syntax 2.0 it's possible to pass parameters to the different syntax elements and also to blocks of text. This is used for example to style them. You can set any parameter key/value pair you want. The XHTML renderer will pass these parameters as XHTML attributes to the underlying XHTML representation of the different syntax elements. In XWiki Syntax 1.0 there was no syntax for passing parameters and the only way to do it was to write XHTML directly in the content as shown in the table below.

XWiki Syntax 1.0XWiki Syntax 2.0Generated XHTML
<h1 class="myClass" style="myStyle" id="myId">heading</h1>
(% class="myClass" style="myStyle" id="myId" %)
= heading =
<h1 class="myClass" style="myStyle" id="myId">heading</h1>

Other syntaxes

The following other syntaxes are implemented in XWiki Enterprise 1.6 and later:

The implementation for these syntaxes is not fully finished yet. For example support for links is not working perfectly yet. We also need to define if we want to extend the original syntaxes to support XWiki-specific features like ability to link to another sub-wiki.
