Because the user may switch version, and have their options grayed out, it is important to trim these options down to what is supported by the version. The trim() function in BibleInformationServiceImpl is responsible for trimming down options that are not supported by particular layouts (e.g. normal, interlinear, interleaved, column view) and reducing the requested options to those that are supported by the selected options.

What is a LookupOption

The LookupOption defines the name of the minimum stylesheet required to execute a request. JSwordPassageServiceImpl iterated iterates through the selected LookupOptions and tries to work LookupOptions and works out which stylesheet to use. -

• commentaries.xsl: used for all commentaries

...

• interlinear.xsl: used for all interlinears, that is, where words are matched vertically, for example, with the lexicon line, transliteration line, Greek or Hebrew text, etc.

...

• default.xsl: used if no other stylesheet will be used

The stylesheets were originally based on BibleDesktop's stylesheets. As a result, they contain a bit of repetition which could ideally be refactored, given time.

The event "version-changed-{passageId}" where passageId is the column number (indexed from 0) is listened upon. When an event is fired, a new call is made to the server (BIBLE_GET_FEATURES). Its response is the set of features available in the current mode of display (e.g. Interleaved). Options that are not available are grayed out.
