rules_ent

Bazel rules for Ent code generation

[WIP; still very hacky]

Usage

Unless done by gazelle, in the BUILD file of the schema package:

load("@io_bazel_rules_go//go:def.bzl", "go_library")

go_library(
    name = "schema",
    srcs = ["entity.go"],
    importpath = "github.com/cloneable/repo/path/to/schema",
    visibility = ["//:__subpackages__"],
    deps = [
        "@io_entgo_ent//:go_default_library",
        "@io_entgo_ent//schema/field:go_default_library",
    ],
)

Define a go_ent_library in the BUILD file of the target package. go_ent_library can be depend upon like a go_library.

load("@com_github_cloneable_rules_ent//:defs.bzl", "go_ent_library")

go_ent_library(
    name = "ent",
    entities = ["entity"],        # temporarily needed
    gomod = "//:go_mod",          # hopefully only temporarily needed
    importpath = "github.com/cloneable/repo/target/package/ent",
    schema = "//path/to/schema",  # go_library of schema package
    visibility = ["//:__subpackages__"],
)

Define a filegroup with go.mod and go.sum in the BUILD file of the root of the Go module because entc calls the go tool, which expects to find a proper module. This may change in the future.

filegroup(
    name = "go_mod",
    srcs = [
        "go.mod",
        "go.sum",
    ],
    visibility = ["//:__subpackages__"],
)

In your WORKSPACE file:

http_archive(
    name = "com_github_cloneable_rules_ent",
    sha256 = "...",
    strip_prefix = "rules_ent-...",
    urls = ["https://github.com/cloneable/rules_ent/..."],
)
