Overview

Example

load("//meta/rules:go.bzl", "go_binary", "go_library")

go_library(
    name = "lib",
    srcs = [
        "aux.go",
        "main.go",
    ],
    visibility = ["//visibility:private"],
)

go_binary(
    name = "somebin",
    embed = [":lib"],
    visibility = ["//visibility:public"],
)

To build the binary:

bazel build //somedir/someotherdir/some_bazel_package:somebin

To run the binary:

bazel run //somedir/someotherdir/some_bazel_package:somebin

To add dependencies, see:

A More Complex Example

load("//meta/rules:go.bzl", "go_library", "go_binary")

go_library(
    name = "somepkg_lib",
    srcs = [
        "file1.go",
        "file2.go",
    ],
    importpath = "github.com/someorg/somemodule/pkg/somepkg",
    visibility = ["//visibility:private"],
    deps = [
        "//lib/a",
        "//lib/b",
        ...
        "@com_github_blang_semver//:semver",
    ],
)

go_binary(
    name = "somebin",
    embed = [":somepkg_lib"],
    visibility = ["//visibility:public"],
    x_defs = {"github.com/someorg/somemodule/version.Version": "{BUILD_VERSION}"},
)

Note: the dependencies can be autogenerated with Gazelle.
