Command Line Interface (CLI)

Reference for all Pynenc CLI commands and options.

Basic Usage

pynenc --app <app_module> <command> [options]

The --app option specifies the Python module containing your Pynenc instance. It accepts a module path (e.g., myapp.tasks.app) or a file path (e.g., myapp/tasks.py).

Global Options

Option

Description

--app MODULE

Application module or file path (required for runner and show_config)

-v, --verbose

Enable debug-level logging output

Commands

runner start

Start a task runner for the specified application.

pynenc --app myapp.tasks.app runner start

The runner type is determined by the application configuration (runner_cls). Using the default DummyRunner raises an error — configure a functional runner first.

To stop the runner, send SIGINT (Ctrl+C) or SIGTERM. The runner shuts down gracefully.

Example with environment variable override:

PYNENC__RUNNER_CLS=ThreadRunner pynenc --app myapp.tasks.app runner start

runner show_config

Display the runner configuration for the application.

pynenc --app myapp.tasks.app runner show_config

show_config

Display the full application configuration, including all components and their settings.

pynenc --app myapp.tasks.app show_config

monitor

Start the Pynmon web monitoring interface. The --app option is optional — the monitor can auto-discover registered applications.

pynenc monitor [--host HOST] [--port PORT] [--log-level LEVEL]

Option

Default

Description

--host

127.0.0.1

Host to bind the server

--port

8000

Port to bind the server

--log-level

info

Log level: debug, info, warning, error, critical

Examples:

# Start monitor with auto-discovery
pynenc monitor

# Start with a specific app
pynenc --app myapp.tasks.app monitor --port 9000

# Start with debug logging
pynenc monitor --log-level debug

Note

The monitor requires the monitoring extras to be installed: pip install pynenc[monitor]. It requires Python < 3.13 due to FastAPI/Pydantic v2 dependencies.

After starting, open http://127.0.0.1:8000 in your browser to access the dashboard.

See Monitoring with Pynmon for details on what the monitoring UI provides.
