Python 3Di command line client

Project description

The 3Di command line client

The 3Di command line client allows for

  • Defining and running 3Di scenarios from the command line.
  • Assembling different scenarios as a "suite" that will be run in batch.
  • Management commands, for instance to list currently running simulations.

Entry points

There are different entry points for the 3Di command line client. The main one being

$ 3Di_cmd --help

Usage: 3Di_cmd [OPTIONS] COMMAND [ARGS]...

Options:
  --install-completion [bash|zsh|fish|powershell|pwsh]
                                  Install completion for the specified shell.
  --show-completion [bash|zsh|fish|powershell|pwsh]
                                  Show completion for the specified shell, to
                                  copy it or customize the installation.

  --help                          Show this message and exit.

Commands:
  api        Interact with with the 3Di API
  live       Get real time updates of running simulations
  scenarios  Manage your local scenarios

The output above shows the three sub-commands api, live and scenarios. Those are all commands from the main client. Whenever you install plugins this list can be appended. You can even append this list yourself by writing your own plugin! How to go about doing that, explains the plugins section.

You can invoke the sub-commands also directly, e.g.

$ api --help
Usage: api [OPTIONS] COMMAND [ARGS]...

Options:
  --endpoint [localhost|staging|production]
                                  [default: production]
  --install-completion [bash|zsh|fish|powershell|pwsh]
                                  Install completion for the specified shell.
  --show-completion [bash|zsh|fish|powershell|pwsh]
                                  Show completion for the specified shell, to
                                  copy it or customize the installation.

  --help                          Show this message and exit.

Commands:
  models         List available threedimodels
  organisations  List available organisations
  results        Download results of a simulation
  run-scenario   Run a scenario
  settings       Set default settings
  simulations    List simulations

Dependencies

python >= 3.8

Installation

pip install --user threedi-cmd

Plugins

The 3Di command client has it's own plugin ecosystem. The commands described above are the client core that can be extended by installing 3Di command client packages into the same environment.

An example: You have a virtual environment /home/you/.virtualenvs/3di/bin/python and you install the 3Di command client using pip

pip install threedi-cmd

If you want to add the statistics commands, you'll install the threedi-cmd-statistics package

pip install threedi-cmd-statistics

Now run 3Di_cmd api again. Notice the statistics and customers commands that has been added to the commands overview; they have added through the plugin you just installed.

Usage: 3Di_cmd api [OPTIONS] COMMAND [ARGS]...

  Interact with with the 3Di API

Options:
  --endpoint [localhost|staging|production]
                                  [default: production]
  --help                          Show this message and exit.

Commands:
  customers      List 3Di customers
  models         List available threedimodels
  organisations  List available organisations
  results        Download results of a simulation
  run-scenario   Run a scenario
  settings       Set default settings
  simulations    List simulations
  statistics     3Di API statistics, like session counts etc

Available plugins

Writing your own plugin

The first thing to know is that the plugin discovering mechanism is based on a naming convention. All plugin packages must start with threedi_cmd_, otherwise the main programme will not be able to discover the package and add the commands to the client.

The commands of the plugin package itself must be typer apps.

The threedi-cmd packages ships with two objects that are used to define and register the plugin apps.

@dataclass
class AppMeta:
    app: typer.Typer
    name: str
    help: str
    add_to: Optional[str] = ""


@dataclass
class AppRegistry:
    apps: Dict[str, AppMeta]

So let's say you have an plugin package that is called threedi-cmd-queue that implements a single app called queue_app. You would need to the following for the threedi-cmd client to pick the command up.

AppMeta

"""threedi_cmd_queue/app_definitions.py"""

# these classes are shiped with the threedi-cmd package
from threedi_cmd.plugins.models import AppMeta, AppRegistry
# import your won app
from threedi_cmd_queue.commands.apps import queue_app


queues_meta = AppMeta(
    app=queue_app,
    name="queues",
    help="3Di API queues",
    add_to="api"
)

# fill the registry; we use the name "queues" for the registry as well 
registry = AppRegistry(
    apps={queues_meta.name : queues_meta}
)

Lastly, make sure the registry is available through your top level __init__.py. Following our example the method would reside in threedi-cmd-queue/threedi_cmd_queue/__init__.py

"""Top-level package for threedi_cmd_queue."""

from threedi_cmd_queue.app_definitions import registry

That's it. Publish your package to pypi so that is pip installable.
