Read in a text file from a GitHub repository

Downloads the text file under the specified path from a GitHub repository via GitHub's GraphQL API v4 and returns its content as a string.

Usage

gh_text_file(path, owner, name, rev = "HEAD")

Arguments

path

Path to a directory, relative to the repository root. A character scalar.

owner

Repository owner's GitHub user or organization name. A character scalar.

name

Repository name. A character scalar.

rev

Git revision expression matching the desired Git tree object, e.g. a branch or tag name or another symbolic reference like "HEAD@{yesterday}" or "HEAD~10". A character scalar.

Value

A character scalar, or an empty character vector in case no text file is found under rev:path.

Details

Works for both public and private repositories, for the latter you just need to set up a sufficiently authorized GitHub Personal Access Token (PAT).

Note that nothing is returned in case of a binary file, as if no file at all existed under the given path.
