Author: kevans Date: Mon Feb 19 17:40:19 2018 New Revision: 329593 URL: https://svnweb.freebsd.org/changeset/base/329593 Log: stand/lua: Change boot menu items' names when swapped [Enter] should be moved to the single user menu item when we swap them. Define a non-standard menu entry function "alternate_name" to use for this purpose for ultimate flexibility if we change our minds later. When we're booting single user, make a shallow copy of the menu that we'd normally display and swap the items and their name functions to use alternate_name instead. Toggling single user in the options menu and going back to the main menu will now correctly reflect the current boot setting with the first two menu options and "[Enter]" will always be on the right one. This shallow copy technique has the chance of being quite slow since it's done on every redraw, but in my testing it does not seem to make any obvious difference. shallowCopyTable could likely belong better in a general-purpose utility module, but this (and the key constnats) are the only candidates we have at the moment so we'll drop it into our core stuff for the moment and consider re-organization at a later date.
