Clone this repository: ` git clone https://github.com/Deborah-Digges/pr-bot.git` 9 | 2. Fill in your github credentials(username & password) in `app.properties` 10 | 2. Create a [heroku account](https://www.heroku.com/) and download the [heroku toolbelt](https://toolbelt.heroku.com) 11 | 3. Navigate to the folder where you cloned this repo: `cd pr-bot` 12 | 4. Create a heroku app: `heroku create` 13 | 5. Deploy the code: `git push heroku master` 14 | 6. Ensure that atleast one instance of the app is running: `heroku ps:scale web=1` 15 | 7. List your app with: `heroku apps` 16 | 8. The service is now running at `.herokuapp.com` 17 | 9. Go to the settings page of the repository of interest. 18 | 10. Navigate to `WebHooks and Services` 19 | 11. Click on `Add WebHook` 20 | 12. For `Payload URL` enter `http://.herokuapp.com/v1/PREvent` 21 | 13. Choose `Let me select Individual Events` and choose the `Pull Request Event` 22 | 14. Add Webhook 23 | 15. Get Someone to Open a PR on your repository :-) 24 | 25 | ## To self-host using Docker 26 | 27 | 1. Install [Docker](http://docs.docker.com/installation/) and [Compose](https://docs.docker.com/compose/install/). OSX users can skip above two and install [Docker Toolbox](https://www.docker.com/docker-toolbox) 28 | 2. Move to this directory, and run `docker-compose up web`. It will install all the requirements on the first run 29 | 3. Follow steps 8 through 14 in the previous list. In the `Payload URL` section of the `Add webhook` page of your Github repo settings, add `/v1/PREvent` 30 | 4. For development purposes, you can use [Ngrok](https://ngrok.io) to set up a temporary local tunnel and make your local server accessible via a public URL. 31 | 32 | ## To Deploy on Google App Engine 33 | 34 | 1. Install [Google App Engine SDK for Python](https://cloud.google.com/appengine/downloads?hl=en_US). 35 | 2. Go to [Google Cloud Console](https://console.developers.google.com) and Create a project. [Here](https://cloud.google.com/appengine/docs) is a quickstart. 36 | 3. Copy the application id of the created project and paste it in `application` parameter of `app.yaml` file. 37 | 4. Follow steps 8 through 14 in the [instruction](#instructions-to-set-up-pr-bot) list. In the `Payload URL` section of the `Add webhook` page of your Github repo settings, add `.appspot.com/v1/PREvent` 38 | 5. Open the folder in Google App Engine Launcher as an existing project by Going to File -> Add Existing Application and deploy. 39 | 6. Alternatively, deploy through command line by running `appcfg.py -A update path-to-root-appengine-dir/`. 40 | 41 | ## Configuration 42 | 43 | 1. Customize the `message` in `app.properties` 44 | 2. Customize `new-users` in `app.properties`. When set to true, a comment is only made on a PR made by a new contributor. 45 | 46 | ## Try It Out! 47 | Submit a PR to this repository 48 | 49 | ###### Made with :heart: - [@Deborah-Digges](http://github.com/Deborah-Digges) 50 | -------------------------------------------------------------------------------- /app.properties: -------------------------------------------------------------------------------- 1 | [DEFAULT] 2 | username = 3 | password = 4 | end-point = /v1/PREvent 5 | new-users = true 6 | [contributors] 7 | url = https://api.github.com/repos/{}/{}/contributors 8 | [comments] 9 | message = Hello, @{}!
