pulley lets you work with github pull requests on the comamnd line.

Use shell pipelines to pull data out of pull requests and to update the request with relevant information.

pulley | add-link-to-staging | pulley --publish

See example scripts at xtoddx/pulley-scripts

pulley can read its credentials through git config github.{username|password|repository}, a file named config/pulley.yml under the current directory, or the file ~/.pulley.yml in the current user's home directory.

An example ~/.pulley.yml:

---
:username: xtoddx
:password: topsecret
:repository: xtoddx/pulley

Your pipeline script should always read json from stdin and print json to stdout. You can change the contents of body or title if you add modifed: true to the printed json hash (which lets --publish know to update that pull request).
