rules_cobol

COBOL build rules for Bazel

rules_cobol is a set of Bazel build rules to make working with COBOL in Bazel possible.

Usage

WORKSPACE

First, grab the latest version of rules_cobol and set it up in your WORKSPACE.

# Load `http_archive`
load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

# Preferably, the latest version of `rules_cobol`
RULES_COBOL_VERSION = "0.1.0"

# Download `rules_cobol`
http_archive(
    name = "io_bazel_rules_cobol",
    sha256 = "fcbc86d25e9fa38c86c9b2a34e914d2553c659f3b9b52796560aefb2423af56a",
    strip_prefix = "rules_cobol-{v}".format(v = RULES_COBOL_VERSION),
    urls = [
        "https://github.com/Fuwn/rules_cobol/archive/refs/tags/{v}.zip".format(v = RULES_COBOL_VERSION),
    ],
)

# Load `cobol_rules_dependencies` from `rules_cobol`
load("@io_bazel_rules_cobol//cobol:deps.bzl", "cobol_rules_dependencies")

# Grab `rules_cobol`s dependencies
cobol_rules_dependencies()

BUILD

Next, create a target using the cobol_binary rule in your BUILD file.

# Load `cobol_binary` from `rules_cobol`
load("@io_bazel_rules_cobol//cobol:def.bzl", "cobol_binary")

# Create a binary target named "hello_world"
cobol_binary(
    name = "hello_world",
    srcs = ["HELLO_WORLD.CBL"],
)

HELLO_WORLD.CBL

Finally, create a HELLO_WORLD.CBL file and print "Hello, World!", of course.

000100 IDENTIFICATION DIVISION.
000200 PROGRAM-ID. HELLO_WORLD.
000300 DATA DIVISION.
000400 WORKING-STORAGE SECTION.
000500 77 FOO PIC 99 VALUE 43.
000600 PROCEDURE DIVISION.
000700     DISPLAY "Hello, World!" FOO
000800     STOP RUN.

Now, just run bazel run //:hello_world to build and execute your new COBOL program using Bazel!
