I finished implementing the logic for additional menu decorations.
Here follows a small discription on how to use the new features:
1. The '...' menu item attribute
--------------------------------
This can be added if more information is needed from the user.
Example:
("load" ... "F2" (choose-file "Load file" "" 'load-buffer))
2. The 'when' primitive
-----------------------
Similar to 'if', but in case of #f, the menu items are in dark grey.
Example:
(when (selection-active-any?)
("copy" "E-c" (copy "primary"))
("cut" "E-x" (cut "primary")))
3. The 'check' menu item attribute
----------------------------------
This can be used in order to mark a menu item
in the case when some condition is satisfied.
For instance:
(-> "header"
("on" (check "*" (visible-header?)) (show-header #t))
("off" (check "*" (not (visible-header?))) (show-header #f)))
Three types of checkmarks are used:
* for mutually exclusive items.
o for mutually exclusive environment settings.
v for toggles.
Notice that the above example should be rewritten as a toggle.
4. Implicit rules
-----------------
A certain number of check attributes are set automatically
as a function of the command which is executed. This is so for
make-with
make-line-with
init-env
init-default
More can be added later when needed, although this list should
be kept as small as possible.
In particular, the o-check should never be set manually.
Layout issues
-------------
Notice that a better layout has to be implemented for checkmarks.
At the moment, we append *, o or v before the menu item text,
but this should be improved by using pixmaps and by using indentation.
But the logic is already there.
Some work for David?
--------------------
Maybe David is willing to take care of the following issues,
since he pressed me to implement the additional features :^)
* Capitalize the *first* letters of all menu entry texts.
Capitalization of other letters will be done automatically
if this is set as an option (not implemented yet).
* Add ... wherever needed.
* Put * and v checkmarks whereever needed and use toggling
whenever appropriate. You might wish to write some additional
routines like (toggle-view-header), which you may put in
the preamble of main-menu.scm; I will move them to
an appropriate place.
* Use 'when' whenever really appropriate; if you need some extra routines,
please put them in main-menu.scm as above. Please keep this kind of
changes to a minimum. In particular, don't change the existing 'if's
to 'when's; this will be done later when appropriate.
* Please do *not* make other changes; since we are in the middle of
a big reorganization, so things should be done in the right order.
Note: please perform these changes shortly after the 1.0.0.11 release.
Note: be careful that there are a few menus which are outside progs/menu.
