An editor-wordbreak-map% objects is used with a
text% objects to specify word-breaking criteria for the
default wordbreaking function. See also set-wordbreak-map, get-wordbreak-map, find-wordbreak, and set-wordbreak-func.
A global object the-editor-wordbreak-map is created automatically and used as the default map for all text% objects.
A wordbreak objects implements a mapping from each character to a list of symbols. The following symbols are legal elements of the list:
The presence of a flag in a character’s value indicates that the character does not break a word when searching for breaks using the corresponding reason. For example, if 'caret is present, then the character is a non-breaking character for caret-movement words. (Each stream of non-breaking characters is a single word.)
All ASCII alpha-numeric characters are initialized with
'(caret line selection). All other ASCII non-whitespace
characters except - are initialized with
'(line). All ASCII whitespace characters and - are
initialized with null.
