Subject: bug#69079: [PATCH] Add 'customize-toggle-option' command
Date: Mon, 12 Feb 2024 18:41:39 +0000 [thread overview]
Message-ID: <SJ0PR10MB54882F9EEDA5DB8EA41EDBCDF3482@SJ0PR10MB5488.namprd10.prod.outlook.com> (raw)
In-Reply-To: <86plx1r2uq.fsf@gnu.org>
FWIW, (since 2006) Icicles has this, which is bound
to `M-i M-i` during completion.
With a prefix arg you can toggle options and other
variables whose values are generalized Booleans:
`nil' or non-`nil' (not just `t').
This is for toggling an option's current value; it
does only this: (set SYMBOL (not (eval SYMBOL))).
But the completion predicate determines the proper
candidates (depending on prefix arg).
There are (rightfully) many options whose values
are `nil' for false and non-`nil' for true. If the
command didn't let you toggle such options (with a
prefix arg) then it would be _far_ less useful.
___
Doc string:
Toggle option's value. This makes sense for binary (toggle) options.
By default, completion candidates are limited to user options that
have `boolean' custom types. However, there are many "binary" options
that allow other non-nil values than t.
You can use a prefix argument to change the set of completion
candidates, as follows:
- With a non-negative prefix arg, all user options are candidates.
- With a negative prefix arg, all variables are candidates.
