XWiki Syntax 2.0: All

General

Introduction

2.0 Introduction

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 1.0 syntax (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 bullet 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.

In addition to these XWiki-specific syntaxes we've also changed our underlying rendering engine (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.

Other Syntaxes

1.0 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.

Editing

Paragraphs

2.0 Paragraphs

Paragraphs are text elements separated by 2 or more new lines.

In XWiki Syntax 2.0 new lines are honored which is not the case in XWiki Syntax 1.0 and in Creole Syntax.

Text Formatting

2.0 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).

A new line is a carriage return. A line break is a forced new line that can appear anywhere in the text.

In XWiki Syntax 2.0 new lines are honored which is not the case in XWiki Syntax 1.0 and in Creole Syntax.

  • 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

    • 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="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"

Groups

2.0 Groups

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

Parameters

2.0 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.

Programming

Macros

2.0 Macros

There is only one kind of macro in XWiki Syntax 2.0, which is called by the syntax: {{macroname param1="value1" ... paramN="valueN"}}...{{/macroname}}. For macros without content there's a short notation: {{macroname param1="value1" ... paramN="valueN"/}}

FeatureXWiki Syntax 2.0Result
Rendering Macro with a content
{{code language="java"}}
System.out.println("Hello World!");
{{/code}
System.out.println("Hello World!");
Rendering Macro without content

{{include reference="Space.Page"/}}

The referenced page is included in the current page
Radeox macros cannot be used in XWiki Syntax 2.0. Thus they have been rewritten as Rendering macros.
For the full list of available macros check the Extensions wiki.

HTML

2.0 HTML

In XWiki Syntax 2.0 HTML or XHTML must be entered by using the HTML macro.
XWiki Syntax 2.0Result
{{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"}} .

Scripts

2.0 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 2.0
Velocity script
{{velocity}}
#set ($var = "whatever")
{{/velocity}}
Groovy script
{{groovy}}
def var = "whatever"
