The Effect code makes temporary copies of wavetracks. If Nyquist invokes another effect,
its temporary copy is no longer valid.
My solution is to NOT apply the Nyquist effect results IF some other effect was successfully
invoked in creating them. I do this by counting the effect invocations. If it has changed, then
Nyquist output Is not applied back to the track.
The net result is that Nyquist prompt can invoke other effects, or process the audio itself,
but it cannot do both.
This is a squash of 50 commits.
This merges the capabilities of BatchCommands and Effects using a new
AudacityCommand class. AudacityCommand provides one function to specify the
parameters, and then we leverage that one function in automation, whether by chains,
mod-script-pipe or (future) Nyquist.
- Now have AudacityCommand which is using the same mechanism as Effect
- Has configurable parameters
- Has data-entry GUI (built using shuttle GUI)
- Registers with PluginManager.
- Menu commands now provided in chains, and to python batch.
- Tested with Zoom Toggle.
- ShuttleParams now can set, get, set defaults, validate and specify
the parameters.
- Bugfix: Don't overwrite values with defaults first time out.
- Add DefineParams function for all built-in effects.
- Extend CommandContext to carry output channels for results.
We abuse EffectsManager. It handles both Effects and
AudacityCommands now. In time an Effect should become a special case of
AudacityCommand and we'll split and rename the EffectManager class.
- Don't use 'default' as a parameter name.
- Massive renaming for CommandDefinitionInterface
- EffectIdentInterface becomes EffectDefinitionInterface
- EffectAutomationParameters becomes CommandAutomationParameters
- PluginType is now a bit field.
This way we can search for related types at the same time.
- Most old batch commands made into AudacityCommands.
The ones that weren't are for a reason. They are used by mod-script-pipe
to carry commands and responses across from a non-GUI thread to the GUI
thread.
- Major tidy up of ScreenshotCommand
- Reworking of SelectCommand
- GetPreferenceCommand and SetPreferenceCommand
- GetTrackInfo and SetTrackInfo
- GetInfoCommand
- Help, Open, Save, Import and Export commands.
- Removed obsolete commands ExecMenu, GetProjectInfo and SetProjectInfo
which are now better handled by other commands.
- JSONify "GetInfo: Commands" output, i.e. commas in the right places.
- General work on better Doxygen.
- Lyrics -> LyricsPanel
- Meter -> MeterPanel
- Updated Linux makefile.
- Scripting commands added into Extra menu.
- Distinct names for previously duplicated find-clipping parameters.
- Fixed longstanding error with erroneous status field number which
previously caused an ASSERT in debug.
- Sensible formatting of numbers in Chains, 0.1 not 0.1000000000137
... though harmlessly so. They called to nonstatic member functions of classes
with improper this pointers; though the functions did not use this.
Bind events to nonmember funtions instead. Sometimes just to empty lambdas to
consume the event and ignore it, blocking other handlers.
... it's either the source of the connection that is being destroyed, or other
object (such as an ancestor window) transitively owning it and so causing it to
be destroyed too;
or, the sink is being destroyed, and that sink is a wxEvtHandler (which is
always so for Disconnect, though not for Unbind in case Bind was passed a
member function of a non-wxEvtHandler).
wxWidgets takes care of erasing the connection in such cases.
This removes most calls to Disconnect and Unbind. Many destructors shrank to
nothing.
Notably, in case of popup menu handling, the call to Disconnect is not removable
because the object being destroyed is neither the source nor the sink.
... Assuming that large unsigned magnitudes with high order bit set are not
the problem, but signed negatives of small magnitude may be:
1) Always cast the unsigned to signed in comparisons, not the other way.
Also:
2) Cast unsigned TERM to signed by itself, before subtracting. Don't cast
the result.
3) Rewrite some comparisons by moving subtracted term to other side.

... Problem was a wrongly implemented comparator for wxArray Sort().
The array of points was not really sorted, and results differed with repeated
calls to Sort().
Unlike with std::sort, these comparators are supposed to be trichotomous.
Problem dates to commit 7d5e54e364

... doing that only for the user-visible string, seen in the Manage>About menu
of the effect dialog and in the sorted or grouped Effect/Generate/Analyze
menus.
But don't for the string used internally and written into pluginregistry.cfg,
so that compatibility of that file is preserved.

... Being careful not to use operator == on a default-constructed
std::list::iterator, which violates assertions in the MSVC libraries.
This reverts commit 7fb5ec4b7a.
... and require qualified name access to use the underlying std::list iterators
that return shared_ptr to Track.
Which should not be done very much outside of class TrackList, but a few
places need it.
... This even makes it possible to remove the prohibition of undo and redo
during transport, not that we want to though. Playback and recording will
continue, using track objects that might not be in the current project.
... See commit 3b90538b84 which removed the
only use of the untranslated strings.
Also follows better i18n guidelines for composing the VSTEffect description.
