Hover

Hover allows to provide tooltips for given parts of the text. This can be used for instance to provide help information.

Default Implementation in AnyText

By default, no hover text is provided, but the service is implemented traversing up in the parse tree and asking every rule along to provide a hover text.

Customizations

Hover texts can be customized by overriding the method GetHoverText of the class Rule. Because the default implementation refers to the parent in the parse tree, overriding this method affects all tokens within the range of the given rule, unless there is a more specific implementation of it.
