/*\
title: js/macros/link.js
Implements the link macro.
A special callback function is used to massage links according to the needs of the host platform.
The linkMassager is stored in the `linkMassager` property of the store object. It is a function
that takes a `linkInfo` structure as the only parameter. It contains a hashmap of information
as follows:
{
target: the target of the link
space: an optional space associated with the link
isExternal: true if the link has been determined to be an external link by the default heuristics
isMissing: true if a non-external link references a missing tiddler
classes: an array of strings representing the CSS classes to be applied to the link. The default classes are already applied
href: the href to be used in the link
}
The linkMassager can modify the `classes` and `href` fields as required.
