redditadmin 0.1.2

Extensible Python administrative bot

Reddit Admin

Plugin-based, extensible administrative Reddit bot framework capable of managing and running multiple 'plugins' (i.e. scripts) asynchronously. Built on top of the PRAW API client wrapper.

It includes a working implementation of the bot itself and tools to build plugins for the bot to run.

Installation

pip install redditadmin

For instructions on installing Python and pip see "The Hitchhiker's Guide to Python" Installation Guides.

Quickstart

reddit-admin requires two things in order for it to work:

• Valid OAuth script application credentials i.e. client_id, client_secret, username, password and user_agent (see more about that here)
• A list of plugins (will discuss more about how to implement these later)

Assuming that both of these are provided for, the bot may be run in this way:

from redditadmin import get_reddit_admin, BotCredentials

# Enter the OAuth credentials into the BotCredentials constructor
bot_credentials = BotCredentials(
    client_id="example_id",
    client_secret="example_secret",
    user_agent="example_useragent",
    username="example_username",
    password="example_password"
)

# List of plugins provided by the user
plugins = [plugin1, plugin2, ...]

# Built-in function to get an instance of the reddit-admin bot
reddit_admin = get_reddit_admin(
    plugins=plugins
)

# Running the bot
reddit_admin.run(
    bot_credentials=bot_credentials,
    listen=False # (Default value)
)

NOTE: RedditAdmin.run() is a blocking command, meaning that no further code will execute until either the RedditAdmin.stop() function is called elsewhere, or if the bot receives a SIGINT or SIGTERM signal.

Console output:

redditadmin.core : Initializing the bot
Asynchronous Plugins Executor : Initializing Plugins Executor
Asynchronous Plugins Executor : Retrieving initial program commands
Asynchronous Plugins Executor : Executing initial program commands
Asynchronous Plugins Executor : Running program 'plugin1_program'
Asynchronous Plugins Executor : Running program 'plugin2_program'
Asynchronous Plugins Executor : Programs Executor initialized
redditadmin.core : Bot successfully initialized
redditadmin.core : The bot is now running

Bot modes

The bot runs in two modes: 'listening' mode and 'autonomous' mode. In listening mode, the bot is capable of receiving commands through the console input, while in autonomous mode, the bot only responds to system signals (e.g. SIGINT).

Listening mode bot commands:

• status - displays the status of running plugin programs
• run - runs a plugin program (provided one is not already running)
• shutdown/quit/exit - shuts down the bot

Plugins

Plugins are mini-applications run and managed by Reddit Admin which instantiate a specific task or program.

The redditadminplugins Python package contains some useful plugins which may be adapted to the user's needs (see more here).

To create a custom plugin, you need to do 2 things:

• To implement a Program
• To implement a Plugin based on the implemented program

For example, we may create a plugin which automatically posts a submission to the r/test subreddit when run as follows:

Program:

from redditadmin import Plugin, Program, get_reddit_admin


class MyProgram[Program]:
    """The program to post our submission"""

    def __init__(praw_reddit):
        super().__init__("My Program")
        self.praw_reddit = praw_reddit

    def execute(self, *args, **kwargs):
        """Overriden from the Program superclass"""

        self.praw_reddit.subreddit('test').submit(
            title="Testing 123",
            url="https://google.com"
        )

Plugin:

class MyPlugin[Plugin[MyProgram]]


"""The plugin for our program"""


def __init__():
    super().__init__("myprogram")


def get_program(self, reddit_interface):
    """Overriden from Plugin superclass"""

    praw_reddit = reddit_interface.praw_reddit

    return MyProgram(praw_reddit)

Voila! We may now supply our plugin to the bot and run it just as we did before

plugin = MyPlugin()
bot_credentials = ...

reddit_admin = get_reddit_admin(
    plugins=[plugin]
)

reddit_admin.run(
    bot_credentials=bot_credentials
)
