## Available Macros

[[Anchor(args)]]

Inserts an anchor into a page.

[[Children(args)]]

Inserts an alphabetic list of all sub-pages (children) of the current page into the output. Accepts one parameter:

• depth: how deep to mine for pages. Default is one level.

Example usage: [[Children(depth=3)]]

[[Column(args)]]

Allows content to be split into columns. This macro must first start with a declaration of the number of columns you want to use: [[Column(3)]] Then you must use the macro twice to indicate where a column starts and ends:

[[Column(start)]]content[[Column(end)]]

Attributes may be applied by separating name/value pairs with a comma. Example: [[Column(start, class=myclass)]]

[[Contributor(args)]]

This macro will generate a link to a contributor's page with the contributor's name as the link text. It accepts either the contributor's ID, username, or name. NOTE: to use a name, it must be identical to their contributor page.

[[Div(args)]]

Allows content to be wrapped in a <div> tag. This macro must be used twice: [[Div(start)]] to indicate where to create the opening <div> tag and [[Div(end)]] to indicate where to close the resulting <div> tag. Attributes may be applied by separating name/value pairs with a comma. Example: [[Div(start, class=myclass)]]

[[File(args)]]

This macro alternately generates a link to a file or embeds the file for display (only valid for CDF files and images). The first argument is the filename.

• digits and unit are interpreted as the width attribute (ex. 120, 25%) for the file/image
• right, left, top or bottom are interpreted as the alignment for the file (currently, only applies to images)
• link=some Link... replaces the link to the file source by the one specified using link. If no value is specified, the link is simply removed.
• nolink means without link to image source (deprecated, use link=)
• key=value style are interpreted as HTML attributes or CSS style indications for the file. Valid keys are:
align, border, width, height, alt, desc, title, longdesc, class, id and usemap
• border can only be a number
• altimage is only valid for CDF files. It is ignored for other file types.
• details indicates wether to display file information (size, etc.). Defaults to: on, Accepts: false, no, off, hide, hidden, none.
The single attribute nodetails is an alternative.

Examples:

• [[File(mydoc.pdf)]] # simplest
• [[File(mydoc.pdf, alt="My document")]] # ALT text. For images, this is the "alt" attribute. For files, the "title" attribute.
• [[File(mydoc.pdf, desc="My document")]] # Link text. If none is provided, the filename will be used.
• [[File(mydoc.pdf, details="off")]] or [[File(mydoc.pdf, nodetails)]] to link a file and NOT display file metadata.

Examples (CDF):

• [[File(prog.cdf, width=300, height=500)]] # with embed width and height sizes
• [[File(prog.cdf, width=300, height=500, altimage=prog.png)]] # CDF file with sizes and alternate image to show if CDF plugin isn't available.
