The Probot framework is primarily used for building GitHub Apps, and it is based on Node.js, not Python. However, you can build GitHub Apps using Probot to capture information about GitHub events and respond to them. Here's an overview of how Probot works [1][2]:
1. Setup: Start by creating a GitHub App on GitHub and installing it in a repository or organization. Configure the app's settings, permissions, and event subscriptions on GitHub.
2. GitHub Events: GitHub generates events for various activities such as issue comments, pull requests, pushes, etc. Probot listens for these events and triggers specific functions when they occur.
3. Probot App: Write a Probot app using JavaScript in Node.js. The app is hosted and runs on a server (e.g., Heroku) that listens for incoming webhooks from GitHub.
4. Event Handling: Define event handlers in your Probot app. These handlers are functions that execute when specific GitHub events occur. You can use Probot's built-in event handling functions or create custom handlers.
5. GitHub API: Use the GitHub API to fetch information about the repository, issues, pull requests, comments, and more. The Probot app can make authenticated API calls to GitHub on behalf of the app's installation.
6. Response Actions: Based on the received events and the information from the GitHub API, the Probot app can take various actions, such as:
* Posting comments on issues or pull requests.
* Labeling or closing issues.
* Triggering CI/CD pipelines.
* Sending notifications or messages to users.
Here's an example of how a Probot app might look in JavaScript:
```
const { Probot } = require('probot');
module.exports = app => {
app.on('issues.opened', async context => {
// Get information about the issue
const issue = context.payload.issue;
// Respond to the issue with a comment
const comment = context.issue({ body: 'Thanks for opening this issue!' });
await context.github.issues.createComment(comment);
});
};
```
In this example, the Probot app listens for the `issues.opened` event. When a new issue is opened in a repository where the app is installed, it responds with a comment.
While Probot is primarily used with Node.js, there are similar frameworks like pygithub for Python that allow you to interact with GitHub's `REST API`. You can use these Python libraries to build GitHub bots or automation, although they may not offer the same comprehensive framework as Probot for Node.js.
