• GitHub setup information to use

  create_github_token(
    scopes = c("repo", "user", "gist", "workflow"),
    description = "RStudio Workbench",
    host = "https://github.coecis.cornell.edu/"
  )

• Change links to all the repos to use the enterprise server

gradereportr

• Change the API endpoint URL for the package to collect the data

• Can change the API endpoint in gh() using

  gh(
    ...,
    .token = gh_token(api_url = "https://github.coecis.cornell.edu"),
    .api_url = "https://github.coecis.cornell.edu"
  )

• Use an option to store api URL. Then automatically use this in the package wherever gh() is used. If that option is NULL, then use the default Github URL. See this example from blogdown.

ghclass

• Does it work with Github Enterprise? See this issue.
