Snowden

This little tool allows users to be notified when one or more of their watched files or folders are included in a new or updated Github pull request, so they can review the changes made on them.

Dependencies

Go >= 1.7

This program is designed to work in conjunction with https://github.com/adnanh/webhook. Take a look at its documentation to know more about how install and configure it.

You'll also need to register Snowden as a Slack application to obtain the credentials required to send messages. Go to https://api.slack.com/apps?new_app=1 for more information.

Usage

• Download an install Snowden: go get github.com/svera/snowden

• Create a configuration file etc/webhook/snowden.yml. You can follow the provided snowden.sample.yml as an example.

• Add the following to webhooks' hooks.json configuration file and launch it:

  [
      {
          "id": "snowden",
          "execute-command": "/path/to/snowden/executable",
          "command-working-directory": "/path/of/working/directory",
          "response-message": "I got the payload!",
          "response-headers":
          [
              {
                  "name": "Access-Control-Allow-Origin",
                  "value": "*"
              }
          ],
          "pass-arguments-to-command":
          [
              {
                  "source": "payload",
                  "name": "action"
              },
              {
                  "source": "payload",
                  "name": "repository.owner.login"
              },
              {
                  "source": "payload",
                  "name": "repository.name"
              },      
              {
                  "source": "payload",
                  "name": "number"
              },
              {
                  "source": "payload",
                  "name": "pull_request.title"
              },
              {
                  "source": "payload",
                  "name": "pull_request.body"
              }            
          ]
      }
  ]
  

• Head to your Github repository settings and add a new webhook that triggers with pull request events, setting its URL to <webhooks server domain>/hooks/snowden.

You can also run it manually (without relying on webhooks server) for testing purposes. Snowden expects 6 parameters, in this order:

• The event that thrown the webhook. Snowden only responds to opened and reopened. Read https://developer.github.com/v3/activity/events/types/ for more information.
• The pull request owner.
• The repository name where the pull request is aimed.
• The pull request number.
• The pull request title.
• The pull request description.
