Add a Sendable* overload so pointers to sendable objects work appropriately.
Otherwise an AddLW(this) in a child (which is a Sendable*) could be a
different pointer than a void* to the same object.
For example:
AnalogInput constructor calls AddLW(this)
AnalogPotentiometer constructor calls AddChild(analog input pointer)
Also add handling for the child object moving (if it's Sendable).
These were incorrect and exhibited as warnings on more recent versions of
clang (notably on Mac).
- Use pointers instead of references internally in GenericHID and *Drive
- Leave PIDBase, PIDController, and Resource non-moveable
- Remove the atomic from m_disabled in NidecBrushless
- Make Timer and Trigger copyable as well as moveable
- Implement custom move constructor/assignment for SendableChooserBase
Also comment out some unused variables that caused clang warnings.
This removes the name and subsystem from individual objects, and instead
puts this data into a new singleton class, SendableRegistry. Much of
LiveWindow has been refactored into SendableRegistry.
In C++, a new CRTP helper class, SendableHelper, has been added to provide
move and destruction functionality.
Shims for GetName, SetName, GetSubsystem, and SetSubsystem have been added
to Command and Subsystem (both old and new), and also to SendableHelper to
prevent code breakage.
This deprecates SendableBase in preparation for future removal.
This is the C++ version of #1682.
The old command framework is still available, but will be deprecated.
Due to name conflicts, the new framework is in the frc2 namespace.
Eventually (after the old command framework is removed in a future year)
it will be moved into the main frc namespace.
Instead of being called asynchronously by NetworkTables, they are now called by updateValues() synchronously with the main loop, just like the getters.
std::scoped_lock was introduced in C++17 and is strictly better than
std::lock_guard as it supports locking any number of mutexes safely.
It's also easier to use than std::lock for locking multiple mutexes at
once.
SendableBuilder.setActuator() sets the .actuator key in the network table
so dashboards can change behavior on the client side if desired, and also
sets a local flag (retrievable via isActuator()).
Both make drive bases actuators and call setSafeState on them.
This echos back the "selected" value to the "active" key to enable dashboards
to display positive feedback to the user that the value is actually set on
the robot side.
Also fixes SendableChooser so it can be safely added to multiple tables.
Changes to "selected" in any table will result in all "active" values being
updated.
Now that adding SendableChooser to multiple tables is supported, an ".instance"
key enables dashboards to treat the same SendableChooser as a common instance
if desired.
This indicates whether or not the Sendable listeners are installed.
It is set to true when SendableBuilder.startListeners() starts the listeners,
and set to false when SendableBuilder.stopListeners() stops the listeners.
This allows dashboards to choose to change their widget display based on
whether or not the value is actually controllable.
The old headers were moved into folders because doing so avoids polluting
the system include directories.
Folder names were also normalized to lowercase.
