Use [pattern matching switch
expressions](https://docs.oracle.com/en/java/javase/17/language/pattern-matching-switch.html)
where possible. This is a JVM 21+ feature which wasn't available until
recently.
If you look at the Java bytecode, this improves performance from an O(n)
runtime check of literally each of the `if (x instanceof y)` checks to
instead be an O(1) tableswitch.

Since Servo has been removed from WPILib, add a RomiServo to replace it
(similar to XRPServo).
For Romi, move allocation of PWM channels to OnBoardIO since Motor and
Servo share channels.
`Trigger.multiPress(N, T)` creates a trigger that fires when there are
at least N rising edges within the last T timespan, eg `multiPress(3,
Seconds.of(1.25))` for 3 rising edges within the last 1.25 seconds.
`Trigger.retryWhileTrue` and `retryWhileFalse` will continuously attempt
to schedule a command while the binding condition is met. This is
similar to `whileTrue` and `whileFalse`, but will reschedule the command
if it ends or is canceled while the binding condition is still met,
rather than requiring a new rising edge to reschedule it.
As discussed in the discord. lb-in^2 is the common imperial MOI unit,
e.g. Onshape uses it.
Also, improved the Java docstring for `KilogramMetersSquaredPerSecond`
to explain what it represents.

This pulls in the `mrclib` maven repository as shared libraries, as a
prereq for #8858.
Alternative to #8869, which avoids the unnecessary lockfile entry. This
should be a one-to-one replacement for that PR.
Closes#8869

Since there is no longer a requirement for Subsystems/Mechanisms to be
registered to the command scheduler via a register() call, Mechanism can
be changed to an interface instead to allow for more flexible
inheritance structures.
Specifically, this would allow compatibility with CTRE swerve (which
previously required implementing Subsystem so that it could extend
CTRE's base class).
This updates gamepad trigger naming from cardinal-style face buttons
(`northFace/southFace/eastFace/westFace` and
`NorthFace/SouthFace/EastFace/WestFace`) to directional naming
(`faceUp/faceDown/faceRight/faceLeft` and
`FaceUp/FaceDown/FaceRight/FaceLeft`) to match the requested API shape.
The change is applied across Java and C++ HID/command layers, along with
related examples and binding metadata.
- **API surface updates (Java)**
- Renamed trigger/event methods in:
- `wpilibj` `Gamepad`
- `commandsv2` `CommandGamepad`
- `commandsv3` `CommandGamepad`
- Mapping preserved:
- `southFace` → `faceDown`
- `eastFace` → `faceRight`
- `westFace` → `faceLeft`
- `northFace` → `faceUp`
- **API surface updates (C++)**
- Renamed trigger/event methods in:
- `wpilibc` `Gamepad`
- `commandsv2` `CommandGamepad`
- Mapping preserved:
- `SouthFace` → `FaceDown`
- `EastFace` → `FaceRight`
- `WestFace` → `FaceLeft`
- `NorthFace` → `FaceUp`
- **Python semiwrap updates**
- Updated `wpilibc/src/main/python/semiwrap/Gamepad.yml` method mappings
to the renamed C++ method names (`FaceDown/FaceRight/FaceLeft/FaceUp`).
- **Callsite migration**
- Updated Java examples/template code and C++ examples/template code to
use the new method names so samples remain aligned with the API rename.
- **Docs/comments alignment**
- Updated related Javadoc/reference text and example comments to use
directional terminology.
```java
// Before
driverController.southFace().onTrue(command);
driverController.eastFace().onTrue(command);
// After
driverController.faceDown().onTrue(command);
driverController.faceRight().onTrue(command);
```
```cpp
// Before
driverController.SouthFace().OnTrue(command);
driverController.EastFace().OnTrue(command);
// After
driverController.FaceDown().OnTrue(command);
driverController.FaceRight().OnTrue(command);

`SetNowImpl` is used somewhat often in unit tests. It is a little bit
goofier to wrap because it takes a C function, so a little bit more work
has to be done to get that wrapped in pybind.
Claude helped.
The initial build file generation for robotpy projects was relatively
naive and purpose built to get `allwpilib` compiling, without supporting
all the available features.
This modifies the generation scripts to be able to support multiple
embedded libraries, which will be necessary for #8858, since `mrclib.so`
will need to be bundled along with the hal libraries. In addition some
cleanup was done to get the wheels looking more like what is in pypi.
Based on discord comments I assume we don't want to support a Nix shell
or flake for use with building allwpilib so we should just ignore these
files so users can have their own
This provides an API for writing a finite state machine compatible with
the commands v3 framework. Individual states in the state machine are
wrappers around command objects (which may themselves be state
machines). Transitions between states are defined with a staged builder
DSL similar to command builders, and uses `@NoDiscard` to catch
partially configured transitions.
The FSM API is meant to handle highly complex cases that the fluent
command chaining DSL and coroutine-based imperative commands cannot
easily represent; specifically, where a command sequence may want to go
back to an arbitrary previous state or skip forward to an arbitrary
future state.
Here's an example from the design doc for a command that will drive to a
known scoring location, aim at a scoring target, and repeatedly shoot
balls until a storage hopper is empty. It also has conditions to stop
shooting and move back to the scoring location if it's jostled away, and
then automatically resume firing.
```java
public Command autoWithStateMachine() {
// Declare the state machine
StateMachine stateMachine = new StateMachine("Auto With State Machine");
// Define states
State getInPosition = stateMachine.addState(drivetrain.driveToScoringLocation());
State aiming = stateMachine.addState(turret.aimAtGoal());
State scoring = stateMachine.addState(shooter.fireOnce());
State celebrating = stateMachine.addState(leds.celebrate());
// Set the initial state. Neglecting this will cause a runtime exception when the state machine starts.
// Teams using the WPILib compiler plugin will get a compiler error if they do not set this
stateMachine.setInitialState(getInPosition);
// Switch to aiming when we reach the scoring location.
getInPosition.switchTo(aiming).whenComplete();
// Set the swerve wheels in an X shape after reaching the scoring location to resist being pushed away.
getInPosition.onExit(() -> Scheduler.getDefault().fork(drivetrain.setX()));
// Then start scoring once the turret is aimed at the goal.
aiming.switchTo(scoring).when(turret::aimedAtGoal);
// Loop the scoring state as long as the hopper has a ball.
scoring.switchTo(scoring).whenCompleteAnd(() -> hopper.hasBall());
// Automatically interrupt any part of the aiming or scoring sequence if
// the robot is moved away from the scoring location and move back into position.
stateMachine.switchFromAny(aiming, scoring).to(getInPosition).when(atScoringLocation.negate());
// Start celebrating once the final ball has been scored.
scoring.switchTo(celebrating).whenCompleteAnd(() -> !hopper.hasBall());
return stateMachine;
}
```
A compiler check is added to detect object construction that's not
followed by post-construction initializer methods (as defined by the
class by placing `@PostConstructionInitializer` on such methods).
`StateMachine.setInitialState` uses this to detect team code that
creates a state machine but does not set its initial state.
`Trigger.getAsBoolean()` behavior has been changed from passing through
the underlying boolean supplier to returning the latest cached signal as
determined by the most recent call to `poll()`. This allows rising and
falling edge triggers to have a consistent return value over an entire
polling cycle, rather than only being high for the _first_ check in a
cycle.
Closes#8309
This provides the ability to simulate parts of the Onboard IMU at the
HAL level. This allows team to use and simulate the IMU in code, and a
follow up PR could be made to the halsim_gui to add a new widget to view
and modify the data graphically.
Since the C++ IMU uses radians for angles that is what I did for the
simulator.
Partially deals with #8845
There's no real need to manually check the `runs-on`, as `runner.os`
provides a universally identifiable string for checking this anyways.

Javadoc now includes 4 MB of fonts for every Javadoc JAR, which we have
18 of, which causes unnecessary bloat to the installer size. This
disables the inclusion of those fonts, using the built-in fallback
included in the Javadoc stylesheet. This also increases the default font
size by 10% after polling the FTC Discord resulted in people asking for
a bigger font.
There were 3 cases failing before.
1. An OpModeRobot with no annotation.
2. An OpModeRobot with an annotation but a parameterless constructor.
3. An OpMode with a UserControls constructor
This PR solves both of these issues. The first one is solved by adding
the null check before setting the user controls instance. That one will
never have an opmode instance.
The second one is solved by falling back to a parameterless constructor
if one with a parameter is not found.
The 3rd one is solved by using the annotation type rather than the
instance for constructor lookup.
Also fixes ExpansionHubSample's missing annotations.
Right now, the `zipBaseName` variable in various publish.gradle files
contains the group ID and artifact ID for use by the combiner, however,
they are also duplicated in `artifactGroupId` and `baseArtifactId`,
leading to potential mistakes if they aren't updated together. This
fixes that by adding a new utility function `makeZipBaseName` to
automatically create the right name given a group ID and artifact ID.
This also fixes publishing for thirdparty subprojects, which didn't
update `zipBaseName`.
