Class Method Details

.generate(name, properties_and_options = {}) ⇒ Object

Generate a screen pattern from a specification

Options:

:force_fields

If true, the fields will be positioned in-line, even if there is matching text or cursor there. :force_fields takes precedence over :force_cursor.

:force_cursor

If true, the cursor will be positioned in-line, even if there is matching text or fields there. :force_cursor may also be a Regexp, in which case the regexp must match in order for the field to be replaced. :force_fields takes precedence over :force_cursor. :force_cursor defaults to the regexp /s/

:ignore

If specified, this is an array of [row, col0..col1] ranges.
