## Bazel Configuration Flags
##
## `.bazelrc` is a Bazel configuration file.
## https://bazel.build/docs/best-practices#bazelrc-file
###############################################################################

# https://bazel.build/reference/command-line-reference#flag--enable_platform_specific_config
common --enable_platform_specific_config

# Enable the only currently supported report type
# https://bazel.build/reference/command-line-reference#flag--combined_report
coverage --combined_report=lcov

# Avoid fully cached builds reporting no coverage and failing CI
# https://bazel.build/reference/command-line-reference#flag--experimental_fetch_all_coverage_outputs
coverage --experimental_fetch_all_coverage_outputs

# Required for some of the tests
# https://bazel.build/reference/command-line-reference#flag--experimental_cc_shared_library
common --experimental_cc_shared_library

# Sensible Defaults

build --incompatible_enable_cc_toolchain_resolution=true

# Require Platform Transitions
## This works by setting the targte platform to an invalid platform
## and each `x_binary()` and `x_library()` rule unfortunately needs
## to tag itself with `platform_missing` to get excluded from glob
## builds like `build //...` but still have a way to include them
## by removing the filter line for things like Rust Analyzer.

build --platforms=//bazel/platforms:missing

## Unique configuration groups
###############################################################################

# Enable use of the nightly toolchains.
build:nightly --@rules_rust//rust/toolchain/channel=nightly

# Enable rustfmt for all targets in the workspace
build:rustfmt --aspects=@rules_rust//rust:defs.bzl%rustfmt_aspect
build:rustfmt --output_groups=+rustfmt_checks

# Enable clippy for all targets in the workspace
build:clippy --aspects=@rules_rust//rust:defs.bzl%rust_clippy_aspect

# Enable unpretty for all targets in the workspace

# `unpretty` requires the nightly toolchain. See tracking issue:

## Bzlmod
###############################################################################

# A configuration for disabling bzlmod.
common:no-bzlmod --noenable_bzlmod --enable_workspace

# Disable the bzlmod lockfile, so we don't accidentally commit MODULE.bazel.lock
common --lockfile_mode=off

###############################################################################
## Custom user flags
##
## This should always be the last thing in the `.bazelrc` file to ensure
## consistent behavior when setting flags in that file as `.bazelrc` files are
## evaluated top to bottom.
