Github GraphQL to recursively list all files in the directory

Question

I want to use the GraphQL Github API to recursively list all files contained in the directory. Right now my query looks like this:

{
  search(first:1, type: REPOSITORY, query: "language:C") {
    edges {
      node {
        ... on Repository {
          name
          descriptionHTML
          stargazers {
            totalCount
          }
          forks {
            totalCount
          }
          object(expression: "master:") {
            ... on Tree {
              entries {
                name
                type
              }
            }
          }
        }
      }
    }
  }
}

However, this only gives me only the first level of directory contents, in particular some of the resulting objects are again trees. Is there a way to adjust the query, such that it recursively list the contents of tree again?

There is no way to recursively iterate in GraphQL. However, you can do so programmatically using a query variable:

query TestQuery($branch: GitObjectID) {
 search(first: 1, type: REPOSITORY, query: "language:C") {
    edges {
      node {
        ... on Repository {
          object(expression: "master:", oid: $branch) {
            ... on Tree {
              entries {
                oid
                name
                type
              }
            }
          }
        }
      }
    }
  }
}

Start with a value of null and go from there.

But probably this will change in the near feature. For example latest github version is v4 https://developer.github.com/v4/explorer/
