# Command Reference

## `dplay http`

Starts the Django HTTP development server.

Startup sequence:

```text
repository
→ virtualenv
→ config
→ environment encryption
→ Redis flush
→ static collection
→ Celery worker + beat
→ Celery readiness wait
→ existing Django server stop
→ browser
→ runserver
```

## `dplay ssl`

Starts the HTTPS development server.

It performs the HTTP startup sequence plus certificate validation/generation
and launches Django with `runserver_plus`.

## `dplay worker`

Starts the Celery worker in the foreground.

The command uses the active virtualenv Python executable and the configured
`DJANGO_SETTINGS_MODULE`.

## `dplay certs`

Force-regenerates local TLS certificates using the current configuration.

## `dplay logs`

Streams application logs.

```bash
dplay logs
dplay logs users
dplay logs mailer --level ERROR
dplay logs django --no-follow -n 100
```

## `dplay system doctor`

Runs:

- Python version check
- Redis reachability check
- PostgreSQL reachability check
- Celery executable check

## `dplay system reset`

Stops Celery worker/beat processes and flushes Redis.

This is a destructive **development-environment** operation because
`redis-cli flushall` removes all data from the selected Redis instance.
Do not run it against production Redis.
