sopel-github 0.5.0

GitHub plugin for Sopel

sopel-github

GitHub plugin for Sopel IRC bots.

Installation

sopel-github is hosted on PyPI, and all you need to install it is pip:

pip install sopel-github

Requirements

sopel-github requires Sopel 8.0+ running on Python 3.8 or higher.

If you need to use this plugin on an older version of Sopel, the older sopel_modules.github package might work, but it is no longer updated.

Optional features

References to :named_emoji: in titles & comments can be converted to Unicode in the output. If you want this feature, install the plugin's emojize extra:

pip install sopel-github[emojize]

Note: GitHub also supports some non-standard emoji names such as :shipit: that don't have a Unicode equivalent, so you might still see some :named_emoji: in the plugin's output.

Out-of-the-box Functionality

Detects when GitHub URLs are posted and takes over URL handling of them, pretty printing details of:

• Commits
• Issues
• Issue Comments
• Pull Requests
• Pull Request Comments
• Repositories

Also pretty prints repository details on command, using either .gh user/repo or .github user/repo. If you omit the user, it will assume your IRC nick is the user. For example:

<@maxpowa> .gh sopel-github

Nuisance reduction

This plugin looks for bare references to issues/PRs the same way GitHub does in comments. If the current channel is associated with a repo, the minimum valid reference is e.g. #1, which is often unhelpful. Anecdotally, chat users talk about their number-one (or two, or three) favorite something much more often than they reference the project's very oldest issues.

For this reason, sopel-github ignores any single-digit bare references by default. Your installation can use the shortest_bare_number setting in the [github] config section to set a different minimum length.

API Keys & Usage

GitHub's API has some fairly lenient unauthorized request limits, but you may find yourself hitting them. In order to prevent yourself from hitting these limits (and potentially being blacklisted), you should generate GitHub API keys for yourself. Fill out the information at https://github.com/settings/applications/new and then populate your configuration with your newly generated client key and secret.

IF YOU PLAN ON USING WEBHOOK FUNCTIONALITY: You must properly fill out the "Authorization callback URL" to match the external URL you plan to use for the webhook.

Webhook Functionality

Webhook functionality is disabled by default. It requires slightly more technical knowledge and configuration may vary depending on your system.

Configuring Webhooks

There are two possible ways to set this up: behind a proxy or directly exposed to the web.

Configuring behind a proxy

This is the recommended way of configuring the webhook functionality, as there may be security flaws in the other method.

First, configure the GitHub module. You may do so by running sopel --configure-modules or changing the config file directly.

[github]
webhook = True
webhook_host = 127.0.0.1
webhook_port = 3333
external_url = http://bad.code.brought.to.you.by.maxpowa.us/webhook

The above configuration is only listening on localhost (127.0.0.1), because I'm using a reverse proxy in nginx to proxy /webhook to port 3333. The reverse proxy configuration would be fairly simple, as shown below. /auth must be included to match the "Authorization callback URL" you set when generating the API keys.

location ~ /(webhook|auth) {
    proxy_pass http://127.0.0.1:3333;
}

Configuring exposed to the web

If you're not using a proxy, your config will look something like this:

[github]
webhook = True
webhook_host = 0.0.0.0  # Or a specific interface
webhook_port = 3333
external_url = http://your.ip.here:3333/webhook

Creating hooks

As an OP+ in a channel, you may type .gh-hook user/repo. You will see some informational text on what you need to do to finalize the hook, including a link to click to authorize the creation of the webhook. You will be required to authorize the GitHub application to read/write your webhooks (see L170-171) but this should be the only extra permission we need.

<@maxpowa> .gh-hook maxpowa/sopel-github
<Sopel> Successfully enabled listening for maxpowa/sopel-github's events in
        #inumuta.
<Sopel> Great! Please allow me to create my webhook by authorizing via this
        link: <git.io link>
<Sopel> Once that webhook is successfully created, I'll post a message in here.
        Give me about a minute or so to set it up after you authorize. You can
        configure the colors that I use to display webhooks with .gh-hook-color

After you've authorized the webhook creation, you will be redirected to a simple page informing you that the bot succeeded/failed creating your hook. Assuming it succeeded, you should see a generic message appear in the channel you activated it in.

Customizing hooks

You may customize the colors that each part of the hook takes on. After setting the new colors, Sopel will reply with a sample of the new colors, e.g.:

<@maxpowa> .help gh-hook-color
<Sopel> .gh-hook-color <repo> <repo color> <name color> <branch color> <tag color> <hash color> <url color>

<@maxpowa> .gh-hook-color maxpowa/Inumuta 13 15 6 6 14 2
<Sopel> [maxpowa/inumuta] Example name: maxpowa tag: tag commit: c0mm17 branch: master url: http://git.io/
<@maxpowa> Unfortunately, IRC colors don't show up on GitHub.
