Functions

def getHlAtt(app, n, highlights, isSlot)

Get the highlight attribute and style for a node for both pretty and plain modes.

Parameters

app : obj

The high-level API object

n : int

The node to be highlighted

highlights : set|dict

The nodes to be highlighted. Keys/elements are the nodes to be highlighted. This function is only interested in whether n is in it, and if so, what the value is (in case of a dict). If given as set: use the default highlight color. If given as dict: use the value as color.

isSlot : boolean

Whether the node has the slotType

Returns

hlCls : dict

Highlight attribute, keyed by boolean 'is pretty'

hlStyle : dict

Highlight color as css style, keyed by boolean 'is pretty'

def getPassageHighlights(app, node, query, cache)

Get the highlights for a whole passage.

Parameters

app : obj

The high-level API object

node : int

The node of a passage (typically a chapter, or something that is occupies a page in the browser)

query : string

A query to run, and whose results will be highlighted (as far they occur in the passage)

cache :  dict

A cache that holds run queries and their results. Useful when we browse many chapters and want to show the highlights of the same query.

def getTupleHighlights(api, tup, highlights, colorMap, condenseType)

Get the highlights for a tuple of nodes.

The idea is to mark the elements of a tuple of nodes with highlights, respecting a given set or dict of highlights and a color map.

This is a bit of an intricate merging operation.

Parameters

app : obj

The high-level API object

tup : tuple of int

The tuple of nodes to be highlighted

colorMap : dict

A mapping of tuple positions to colors. Member i of tup should be highlighted with color colorMap[i].

condenseType : string

The type of node that acts as the basis of a pretty display. The nodes in the given tup will be distributed over as many nodes of condenseType as they occur in.

highlights : set|dict

The nodes to be highlighted. Keys/elements are the nodes to be highlighted. This function is only interested in whether the members of tup are in it, and if so, what the values are (in case of a dict). If given as set: use the default highlight color. If given as dict: use the value as color.
