## 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

# `cargo_build_script` from `rules_rust` requires the use of symlinks so
# symlinks are enabled within this repo as the default toolchain relies on
# them to build Pyo3
# https://bazel.build/docs/windows#symlink
startup --windows_enable_symlinks
build:windows --enable_runfiles

# 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

# Disable network access in the sandbox by default.
build --sandbox_default_allow_network=false

# Do not use the host detected python toolchain. Always use one explicitly
# registered in the WORKSPACE.
common --repo_env=BAZEL_DO_NOT_DETECT_PYTHON_TOOLCHAIN=1

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

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

# Enable unpretty for all targets in the workspace
build:unpretty --aspects=@rules_rust//rust:defs.bzl%rust_unpretty_aspect
build:unpretty --output_groups=+rust_unpretty

# `unpretty` requires the nightly toolchain. See tracking issue:
# https://github.com/rust-lang/rust/issues/43364
build:unpretty --config=nightly

# Convenience configs for enabling linting and formatting
# build:strict --config=rustfmt
build:strict --config=clippy
# build:no_strict --config=no_rustfmt

# When running test enable all linters and formatters

## Incompatibility flags

build --incompatible_disallow_empty_glob=true

# https://github.com/bazelbuild/bazel/issues/12821

# Disable legacy __init__.py behavior which is known to conflict with
# modern python versions (3.9+)

###############################################################################
## 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.
