make.py
make.py is like make but with its build configuration written in Python.
Example
For the following Makefile:
CC=gcc
OUTPUT=build
all: $(OUTPUT)/main
$(OUTPUT)/%.o: %.c
mkdir -p $(dir $@)
$(CC) -MMD -c $< -o $@
$(OUTPUT)/main: $(OUTPUT)/hello.o $(OUTPUT)/main.o
$(CC) $^ -o $@
clean:
rm -rf $(OUTPUT)
.PHONY: clean
-include $(OUTPUT)/*.dThe equivalent Makefile.py is:
from pathlib import Path
from shutil import rmtree
from subprocess import check_call
from make_py import task, rule, phony_task
CC = "gcc"
OUTPUT = "build"
phony_task("all", f"{OUTPUT}/main")
def collect_c_dependencies(target, target_regex_groups):
dep_file = Path(target).with_suffix(".d")
if dep_file.exists():
return dep_file.read_text().split(":")[1].strip().split(" ")
# missing parent directories will be made automatically
@rule(f"{OUTPUT}/%.o", ["%.c", collect_c_dependencies])
def compile_c(ctx):
check_call([CC, "-MMD", "-c", ctx.source, "-o", ctx.target])
@rule(f"{OUTPUT}/main", [f"{OUTPUT}/{o}" for o in ["hello.o", "main.o"]])
def link(ctx):
check_call([CC, *ctx.sources, "-o", ctx.target])
@task()
def clean(ctx):
rmtree(OUTPUT, ignore_errors=True)The commands can be executed by make.py the same way as executing make
For more examples, refer to the examples folder in project root.
