cmdbox 0.2.9.1

cmdbox: It is a command line application with a plugin mechanism.

cmdbox

• It is a command line application with a plugin mechanism.
• Documentation is here.
• With cmdbox, you can easily implement commands with complex options.
• The implemented commands can be called from the CLI / RESTAPI / Web screen.
• The implemented commands can be executed on a remote server via redis.

Install

• Install cmdbox with the following command.

pip install cmdbox
cmdbox -v

• Also install the docker version of the redis server.

docker run -p 6379:6379 --name redis -it ubuntu/redis:latest

Tutorial

• Open the .sample/sample_project folder in the current directory with VSCode.

• Install dependent libraries.

python -m venv .venv
. .venv/bin/activate
pip install -r requirements.txt

• Run the project.

• The localhost web screen will open.

• Enter user01 / user01 for the initial ID and PW to sign in.
• Using this web screen, you can easily execute the commands implemented in cmdbox.

• Let's look at the command to get a list of files as an example.
• Press the plus button under Commands to open the Add dialog.
• Then enter the following.

• Press the Save button once and then press the Execute button.
• The results of the command execution are displayed.

• Open the saved client_time and press the Raw button.
• You will see how to execute the same command on the command line; the RESTAPI URL is also displayed.

How to implement a new command using cmdbox

• Under the sample/app/features/cli folder, you will find an implementation of the client_time mentioned earlier.
• The implementation is as follows. (Slightly abbreviated display)
• Create the following code and save it in the sample/app/features/cli folder.

from cmdbox.app import common, feature
from typing import Dict, Any, Tuple, Union, List
import argparse
import datetime
import logging


class ClientTime(feature.Feature):
    def get_mode(self) -> Union[str, List[str]]:
        return "client"

    def get_cmd(self):
        return 'time'

    def get_option(self):
        return dict(
            type="str", default=None, required=False, multi=False, hide=False, use_redis=self.USE_REDIS_FALSE,
            discription_ja="クライアント側の現在時刻を表示します。",
            discription_en="Displays the current time at the client side.",
            choice=[
                dict(opt="timedelta", type="int", default=9, required=False, multi=False, hide=False, choice=None,
                        discription_ja="時差の時間数を指定します。",
                        discription_en="Specify the number of hours of time difference."),
            ])

    def apprun(self, logger:logging.Logger, args:argparse.Namespace, tm:float, pf:List[Dict[str, float]]=[]) -> Tuple[int, Dict[str, Any], Any]:
        tz = datetime.timezone(datetime.timedelta(hours=args.timedelta))
        dt = datetime.datetime.now(tz)
        ret = dict(success=dict(data=dt.strftime('%Y-%m-%d %H:%M:%S')))
        common.print_format(ret, args.format, tm, args.output_json, args.output_json_append, pf=pf)
        if 'success' not in ret:
            return 1, ret, None
        return 0, ret, None

• Open the file sample/extensions/features.yml. The file should look something like this.
• This file specifies where new commands are to be read.
• For example, if you want to add a package to read, add a new package and prefix to features.cli.
• Note that features.web can be used to add a new web screen.
• If you only want to call commands added in features.cli via RESTAPI, no additional implementation is needed in features.web.

features:
  cli:
    - package: sample.app.features.cli
      prefix: sample_
  web:
    - package: sample.app.features.web
      prefix: sample_web_
args:
  cli:
    - rule:
        mode: web
      default:
      coercion:
        assets:
          - f"{Path(self.ver.__file__).parent / 'web' / 'assets'}"
        doc_root: f"{Path(self.ver.__file__).parent / 'web'}"
    - rule:
        mode: gui
      default:
      coercion:
        assets:
          - f"{Path(self.ver.__file__).parent / 'web' / 'assets'}"
        doc_root: f"{Path(self.ver.__file__).parent / 'web'}"

• The following files should also be known when using commands on the web screen or RESTAPI.
• Open the file sample/extensions/user_list.yml. The file should look something like this.
• This file manages the users and groups that are allowed Web access and their rules.
• The rule of the previous command is allow for users in the user group in cmdrule.rules.
