请告诉我在 Bazel 中拥有多平台 WORKSPACE 的更好方法

Question

这是我实际 WORKSPACE 中的一个示例，使我的项目能够看到 TUT（模板单元测试），无论我是在 Windows 还是 Linux 上测试它们。

new_local_repository(
    name = "win32_tut",
    path = "/d/diego/progs/c++/lib/tut/",
    build_file_content = """
cc_library(
    name = "tut",
    srcs = glob([
        "tut/*.hpp",
    ]),
    hdrs = glob([
        "*.h",
    ]),
    visibility = ["//visibility:public"],
)
""",
)

new_local_repository(
    name = "linux_tut",
    path = "/usr/include/",
    build_file_content = """
cc_library(
    name = "tut",
    srcs = glob([
        "tut/*.hpp",
    ]),
    hdrs = glob([
        "tut.h",
    ]),
    visibility = ["//visibility:public"],
)
""",
)

new_local_repository(
    name = "tut",
    path = ".",
    build_file_content = """
cc_library(
    name = "tut",
    deps = select({
        "@bazel_tools//src/conditions:windows": ["@win32_tut//:tut"],
        "//conditions:default": ["@linux_tut//:tut"],
    }),
    visibility = ["//visibility:public"],
)
""",
)

我的所有 cc_test 规则都成功取决于 "@tut//:tut"。这对我有用，但看起来我在滥用 WORKSPACE 文件。有没有更好的方法来实现这个？

我觉得你的解决方案不错。

it looks like I am abusing the WORKSPACE file

或者，创建一个自定义存储库规则 detects the OS [1], creates a symlink to the d:/diego/progs/c++/lib/tut or /usr/include directory, and creates a BUILD file 只有一个 cc_library，将所有文件放在符号链接下。

看到。

[1] 例如repository_ctx.os.name.lower().startswith("windows")
