Photo of this: You’re working on an Ezar Project, and whenever you want to run the test, you type python3 -m pytest tests/ --verbose --cov=src. When you want to format your code, it is black . && isort .. Lanting’s Lou You, you run away flake8 src tests. Before you know it, you are doing a dozen different commands, and your fellow fellow is doing the same thing in a slightly different way.
This is the place where Mac files work. Originally used for C and C ++ projects, Mac files can be extremely useful in developing common tasks as an easy way to standardize and automatically. Think about a Mac file as a place where you repeatedly describe the shortcut for all the things you repeated.
. Why use Mac files in Plans?
Permanent temperament in your team
When everyone in your team walks make test Instead of remembering the exact pistor command with all its flags, you eliminate the problem of “work on my machine”. The team’s new members can quickly jump and know how to run the format codes, or to deploy the application immediately.
Documents that actually work
Unlike the Redam files that get old, Mac files act as useful documents. When someone moves make helpThey see what works are available and how to use them.
Easy complex workflow
Some works require a number of steps. You may need to install dependence, migrate, run the seed test data, and then start your development server. With a Mac file, it becomes single make dev Order.
. To start with your first -first mac file
Let’s create a practical Mac file in a phased manner. Create a Mac file (no extension) in the root of your project.
!! The infrastructure and help command
This code creates an automated support system for your Mac file that displays all available commands with their detail.
.PHONY: help
help: ## Show this help message
@echo "Available commands:"
@grep -E '^(a-zA-Z_-)+:.*?## .*$$' $(MAKEFILE_LIST) | sort | awk 'BEGIN {FS = ":.*?## "}; {printf " \033(36m%-15s\033(0m %s\n", $$1, $$2}'
.DEFAULT_GOAL := help .PHONY: help It states that “help” is not a real file but a command to run. When you type make helpIt first prints “available commands:” then uses its combination grep And awk To scan the self -Mac file, find all the lines after which command names are followed ## descriptionAnd format them on a good reading list with command names and their explanations.
!! Setup of environment
This code produces three commands of environmental management:
.PHONY: install
install: ## Install dependencies
pip install -r requirements.txt
pip install -r requirements-dev.txt
.PHONY: venv
venv: ## Create virtual environment
python3 -m venv venv
@echo "Activate with: source venv/bin/activate"
.PHONY: clean
clean: ## Clean up cache files and build artifacts
find . -type f -name "*.pyc" -delete
find . -type d -name "__pycache__" -delete
find . -type d -name "*.egg-info" -exec rm -rf {} +
rm -rf build/ dist/ .coverage htmlcov/ .pytest_cache/ install The command operates twice to install both dependent and development tools than the files of the requirements. The Venv command creates a new virtual environmental folder called “Venv” and prints instructions on ways to activate it.
clean The command removes all the dirt files produced during development. These compiled Files (.PYC), cache folders (Packach) Make samples like package information directories, and coverage reports and test catchs.
!! Code quality and testing
This creates code quality commands:
.PHONY: format
format: ## Format code with black and isort
black .
isort .
.PHONY: lint
lint: ## Run linting checks
flake8 src tests
black --check .
isort --check-only .
.PHONY: test
test: ## Run tests
python -m pytest tests/ --verbose
.PHONY: test-cov
test-cov: ## Run tests with coverage
python -m pytest tests/ --verbose --cov=src --cov-report=html --cov-report=term
.PHONY: check
check: lint test ## Run all checks (lint + test) format Command automatically uses your code style using Black for formatting and Ishort for Import Organization.
Lint Command checks whether your code follows the style rules without changing anything. Flack 8 reveals styling violations, while black and assorted checks only run in the mood to see if formatting is needed.
test Command runs test suite. test-cov Runs the test and measures code coverage and produces reports. check Runs both lunting and testing together depending on the command lint And test اØکامات
!! Development workflow
This creates development workflow orders:
.PHONY: dev
dev: install ## Set up development environment
@echo "Development environment ready!"
@echo "Run 'make serve' to start the development server"
.PHONY: serve
serve: ## Start development server
python3 -m flask run --debug
.PHONY: shell
shell: ## Start Python shell with app context
python3 -c "from src.app import create_app; app=create_app(); app.app_context().push(); import IPython; IPython.start_ipython()" dev The command operates first install Order to establish dependence, then print messages of success with the next steps. serve Command launches a flask development server in debug mode.
shell The command has launched an IP -ton shell that is already linked to the context of your flask app, so you can interact with database questions and app functions without manually importing everything.
. More Mac file techniques
!! Using variables
You can describe variables to avoid repetition:
PYTHON := python3
TEST_PATH := tests/
SRC_PATH := src/
.PHONY: test
test: ## Run tests
$(PYTHON) -m pytest $(TEST_PATH) --verbose!! Conditional orders
Sometimes you want different behavior based on the environment:
.PHONY: deploy
deploy: ## Deploy application
ifeq ($(ENV),production)
@echo "Deploying to production..."
# Production deployment commands
else
@echo "Deploying to staging..."
# Staging deployment commands
endif!! File dependent
You can rely on the goals on the files, so they just walk when needed:
requirements.txt: pyproject.toml
pip-compile pyproject.toml
.PHONY: sync-deps
sync-deps: requirements.txt ## Sync dependencies
pip-sync requirements.txt

. The best action and indicators
Some of the best procedures to follow this when writing a Mac file are:
- Do not control your macific. If a task is getting complicated, consider moving the logic to a separate script and calling it to Mac.
- Choose command names that clearly indicate what they do. The test is better than making the Mac, and making the dave setup is far more clear than the setup.
- For commands that do not make files, always to them. Announce as a fan. If someone makes a file like your command, it prevents problems.
- Organize your Mac files together with group functionality.
- Make sure all your orders work from a fresh clone of your storage. The process of broken setup does not disappoint new supporters.
. Conclusion
Mac files may seem like an old school tool, but they are effective for Azigar’s projects. They provide a permanent interface for normal tasks and help new supporters faster fruitful.
Just create a basic Mac file with install, test, and help commands. As your project grows and your workflow becomes more complicated, you can add more goals and dependence as needed.
Remember, the purpose is not to make a very smart or complex Mac file. This is to make your daily development work easier and more reliable. Keep it easy, keep it useful, and let your Mac file become a command center that brings orders into your project chaos.
