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
