A collection of bazel utilities for FRC

You can include BazelRIO in your project like so:

http_archive(
    name = "bazelrio",
    url = "https://github.com/bazelRio/bazelRio/archive/refs/tags/0.10.0.zip",
    sha256 = "18b109dbd5204910600823e6c9ff405fa7ed7c43d0a78f24077f8187311745a9",
    strip_prefix = "bazelRio-0.10.0/bazelrio",
)

load("@bazelrio//:deps.bzl", "setup_bazelrio_dependencies")

setup_bazelrio_dependencies()

load("@bazelrio//:defs.bzl", "setup_bazelrio")

setup_bazelrio()

You must copy the .bazelrc file from the C++ or Java example into your project workspace and update your BUILD and WORKSPACE files in the same fashion.

BazelRIO provides a RoboRIO target for easy cross-compilation.

bazel build <target> --platforms=@bazelrio//platforms/roborio

BazelRIO will automatically download an official roboRIO toolchain (from WPILib) for your host OS and use it.

BazelRIO provides rules for robot code targets of multiple languages.

load("@bazelrio//:defs.bzl", "robot_cc_binary")

robot_cc_binary(
    name = "hello",
    team_number = 1337,
    srcs = ["hello.cpp"],
)

BazelRIO will create a cc_binary target named hello, as well as a special target named hello.deploy that can be used to deploy your binary:

bazel run //:hello.deploy --platforms=@bazelrio//platforms/roborio
...
Attempting to connect to roborio-1337-frc.local...
Connected to roborio-1337-frc.local.
Attempting to deploy bazel-out/darwin-fastbuild/bin/hello...
Deployed bazel-out/darwin-fastbuild/bin/hello. Exiting.

robot_java_binary(
    name = "hello",
    main_class = "frc.robot.Main",
    team_number = 1337,
    runtime_deps = [
        "//src/main/java/frc/robot",
    ],
)

BazelRIO will create a java_binary target named hello, as well as a special target named hello.deploy that can be used to deploy your binary. If you are using Kotlin, you must build your code as a kt_jvm_library and add it to runtime_deps, rather than adding Kotlin files directly to srcs.

BazelRIO containts library targets for WPILib and some vendor libraries:

• @bazelrio//libraries/cpp/wpilib/wpilibc
• @bazelrio//libraries/java/wpilib/wpilibj
• @bazelrio//libraries/cpp/ctre/phoenix
• @bazelrio//libraries/cpp/rev/sparkmax
• @bazelrio//libraries/cpp/rev/revlib
• @bazelrio//libraries/cpp/rev/colorsensor
• @bazelrio//libraries/cpp/kauailabs/navx

Simulations (alongside halsim extensions) are supported! Take a look at the C++ example to get started.
