Dyngle

Run lightweight local workflows

Dyngle is a simple workflow runner that executes sequences of commands defined in configuration files. It's like a lightweight combination of Make and a task runner, designed for automating common development and operational tasks.

Basic usage

Create a configuration file (e.g., config.yml) with your workflows:

dyngle:
  flows:
    build:
      - python -m pip install -e .
      - python -m pytest
    deploy:
      - docker build -t myapp .
      - docker push myapp
    clean:
      - rm -rf __pycache__
      - rm -rf .pytest_cache

Run a workflow:

dyngle --config config.yml run build

Configuration

Dyngle reads configuration from YAML files. You can specify the config file location using:

• --config command line option
• DYNGLE_CONFIG environment variable
• .dyngle.yml in current directory
• ~/.dyngle.yml in home directory

Workflow structure

Each workflow (called a "flow") is defined as a list of tasks under dyngle.flows. Tasks are executed sequentially using Python's subprocess module for security.

Example with multiple flows:

dyngle:
  flows:
    test:
      - python -m unittest discover
      - python -m coverage report
    docs:
      - sphinx-build docs docs/_build
      - open docs/_build/index.html
    setup:
      - python -m venv venv
      - source venv/bin/activate
      - pip install -r requirements.txt

Security

Commands are executed using Python's subprocess.run() with arguments split by spaces. The shell is not used, preventing shell injection attacks.

Quick installation (MacOS)
