class editor-wordbreak-map% : class?
superclass: object%

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:

- 'caret

- 'line

- 'selection

- 'user1

- 'user2

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.)

> constructor (new editor-wordbreak-map%) → (is-a?/c editor-wordbreak-map%)

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.

> method (send an-editor-wordbreak-map get-map char)

> char : char?

Gets the mapping value for char. See editor-wordbreak-map% for more information.
