The repository that I am looking at has a great number of issues that I would like to read but it's not manageable while scrolling in GitHub interace. Is there an option to export or print a full list of issues for a repository?
There is an Issues API. To get all issues from a repo, you can use cURL:
This returns a JSON encoded list of all issues. And …
… returns all open issues. Now you just have to convert the JSON to CSV and you are set.
