... This makes it impossible to forget to include the EXPERIMENTAL definitions
(such as when cutting and pasting code) and so get unintended quiet changes of
behavior.
The EXPERIMENTAL flags are now specified instead in new file Experimental.cmake
... because the two macros have the same expansion, and are both checked for
in the --keyword arguments passed to msgfmt by locale/update_po_files.sh.
This commit makes ONLY such changes, and comments in Internat.h. It is big
but quite harmless.
The intention is to introduce a type distinction in a later release, by defining
XXO differently. XXO is used where & characters in strings (for hotkeys of menu
items or control prompts) are permitted, XO where not.
... such as Nyquist Workbench.
I don't fully understand why, but destroying the menu registry items very late,
during the destruction of static objects, causes a crash in memory deallocation,
at least on Mac.
So destroy the menu registry explicitly in application shut-down.
... and we use them to simplify (the misnamed) MenuManager::ModifyToolbarMenus.
It looked wrong that statically constructed menu descriptions should ever hold
constant boolean checkmark values, rather than functions to re-eveluate the
checkmark state as needed.
... They all use the registry.
(This link dependency was not shown in diagrams generated by scripts/graph.pl,
because it was not reflected in Menus.h but was done using extern declarations
within Menus.cpp. That was a cheat, but it let all the other dependencies
be exposed in the graph and mitigated first.)
... removing link dependencies on them from src/menus, so they are now suitable
for moving out into modules.
They are:
Mixer Board
Karaoke (also called Lyrics)
History
Contrast
Plot Spectrum
Their header files are now no longer included anywhere but in their own
implementation files!
... Now, a first-time registered item can specify that it go at the start or end
of the nodes under its parent, or before or after some named node.
Still it might happen that multiple first-time registrations might use the same
ordering hint, and so we must still sort by component name to resolve that
collision arbitrarily.
... before we populate the registry.
This could apply to menu items, or more generally to other registries.
A registry is a tree of items identified by path names. Various code,
that need not coordinate, can specify items to attach to the tree, and the
merging procedure collects them into a single tree that can be visited.
Pathnames imply only an unordered tree. Some visitation ordering must be
imposed on the nodes, and can be remembered in preferences for stability between
runs, independently of accidents of the unspecified sequence of initialization
of file-scope static objects in the various plug-ins. It can be arbitrary --
not constrained to some fixed intrinsic criterion like alphabetical order.
Merging consults the preferences, and also updates them if previously unknown
items are found and inserted. For now, such unknowns just go to the end of
the sequence of siblings, sorted by their path component names.
... which is not yet used for anything.
It could be used to describe textual paths for attaching plug-in menu items.
Strings are only path local, not necessarily globally unique, and may be
left empty for separators and for groups that should be transparent to
path identification.
It may also be empty for certain sub-menus, such as those that group effects
according to the changeable criteria in Preferences.
... Except a few where project or plugin manager state or preferences are
needed to compute the items, so evaluation is delayed, often inside lambdas
Comment "Delayed evaluation" wherever there are exceptions
... There are now four immediate subclasses (SharedItem and Computed Item,
which are final, and SingleItem and GroupItem, which are abstract), which may
serve future purposes more general than menu items. There are further
subclasses specific to menu management.
The former concrete class GroupItem is renamed TransparentGroupItem.
Also allows direct construction of items in lists from shared pointers.
