Converts Gopkg.lock to bazel go_repository workspace rules

Go dep rules for Bazel

See go-dep-bazel-vscode-example for an example project.

Workspace rules

Generate Gopkg.lock file with dep init, and add following rules to your WORKSPACE file:

http_archive(
    name = "com_github_scele_rules_go_dep",
    urls = ["https://github.com/scele/rules_go_dep/archive/4aa1bd3550191b39abded31bcf06d233b67fa8bb.tar.gz"],
    strip_prefix = "rules_go_dep-4aa1bd3550191b39abded31bcf06d233b67fa8bb",
    sha256 = "068d102168fdef7bb9da4f7c699df6b1b1ff25230f6a45e3b8da5e8ab15c6c36",
)

load("@com_github_scele_rules_go_dep//dep:dep.bzl", "dep_import")

dep_import(
    name = "godeps",
    gopkg_lock = "//:Gopkg.lock",
    prefix = "github.com/my/project",
    # Optional: if you want to use checked-in Gopkg.bzl.
    gopkg_bzl = "//:Gopkg.bzl",
)
load("@godeps//:Gopkg.bzl", "go_deps")
go_deps()

This will load all go dependencies expressed in Gopkg.lock into your workspace.

Using checked-in Gopkg.bzl can result in faster builds, since Gopkg.bzl does not need to be generated on the fly. If gopkg_bzl is used, then the checked-in Gopkg.bzl can be updated with:

bazel run @godeps//:update
