Introduction

1.0 Introduction

The XWiki Syntax 1.0 was the first attempt to implement a Wiki-style Syntax in XWiki. It had some limitations and some formatting can only be achieved by inserting raw HTML. We recommend using the newer syntaxes; XWiki Syntax 1.0 is only supported for backwards compatibility.

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

2.0 Introduction

Starting with XWiki 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.

2.1 Introduction

The XWiki Syntax 2.0 has proven to be quite useful and robust in general; however since its introduction a few shortcomings have been found. The corresponding improvements have been consolidated in XWiki Syntax 2.1. Some new features of this syntax are:

  • Homogenize the link and image syntax for better clarity, consistency and extensibility.
  • Added ability to display icons, to embed images via the Data URI scheme, 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.

      • Non-terminal page  in the current space. Example: [[A]] is resolved to the equivalent of [[space:currentSpace.A]], which is the equivalent of [[doc:currentSpace.A.WebHome]]
      • If the current page is non-terminal and the previous 2 checks above did not find an existing page, 2 additional checks are made:
        • Terminal page as sibling in the parent space, only if it exists. Example: The [[B]] link inside the non-terminal page A.C is resolved to the equivalent of [[doc:A.B]]
        • Non-terminal page as sibling in the parent space, regardless if it exists or not. Example: The [[B]] link inside the non-terminal page A.C is resolved to the equivalent of [[space:A.B]], which is the equivalent of [[doc:A.B.WebHome]]
      • Note1 - Absolute links: If the untyped link has 2 or more dot-separated components specified (i.e. that look like a space name and a page name), the above algorithm will resolve the page relative to the current wiki, and not the current space. Example: [[A.B]] can be resolved to either [[doc:currentWiki:A.B]] (if it exists) or to [[space:currentWiki:A.B]] (equivalent of [[doc:currentWiki:A.B.WebHome]]) and not to [[doc:currentWiki:currentSpace.A.B]] or [[doc:currentWiki:currentSpace.A.B.WebHome]].
      • Note2 - Special handling of .WebHome: If the untyped link ends in .WebHome, it will always be handled as a terminal page. Example: [[A.WebHome]] will always be resolved to the equivalent of [[doc:A.WebHome]] and not to [[doc:A.WebHome.WebHome]].
  • parameters: An optional list of space-separated parameters passed to the link. Example: queryString="mydata1=5&mydata2=Hello" anchor="HTableOfContents" target="_blank"
    • queryString: An optional query string for specifying parameters that will be appended to the link target address and used in the rendered URL. Example: url:http://domain.com/path||queryString="mydata1=5&mydata2=Hello" produces target address http://domain.com/path?mydata1=5&mydata2=Hello
    • anchor: An optional anchor name pointing to an anchor defined in the referenced link. Note that in XWiki anchors are automatically created for headings and images. Example: url:http://domain.com/path||anchor="HTableOfContents" produces target address http://domain.com/path#HTableOfContents
    • target: An optional parameter that allows to open link target in new window. Example: target="_blank"

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 [[{caption>>}image: (reference) {||parameters}]]

  • caption: An optional caption. May contain arbitrary XWiki 2.0 syntax but nested link syntax must be escaped using ~. The caption is only supported when the image syntax is the only content of a paragraph. The captioned image may also be wrapped in a link. In this case, the link will contain the image but not the caption.
  • 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 wiki. The image reference will point to an image attached to a page inside that 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.

      • 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%").

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

Parameters

1.0 Parameters

In XWiki Syntax 1.0 there is 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 1.0Generated XHTML
<h1 class="myClass" style="myStyle" id="myId">heading</h1>

<h1 class="myClass" style="myStyle" id="myId">heading</h1>

2.0 Parameters

With XWiki Syntax  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.

(% class="myClass" style="myStyle" id="myId" %)
= heading =

<h1 class="myClass" style="myStyle" id="myId">heading</h1>

In XWiki Syntax 1.0 it was possible to enter Velocity scripts anywhere directly in the page. This can lead to issues for example when the user was involuntarily entering Velocity content. It is also performance hungry for pages not requiring Velocity content. There are several other technical limitations. Same goes for entering Groovy scripts.
