Copy a file from any GitHub repo into the current project

Gets the content of a file from GitHub, from any repo the user can read, and writes it into the active project. This function wraps an endpoint of the GitHub API which supports specifying a target reference (i.e. branch, tag, or commit) and which follows symlinks.

use_github_file(
  repo_spec,
  path = NULL,
  save_as = NULL,
  ref = NULL,
  ignore = FALSE,
  open = FALSE,
  host = NULL
)

Arguments

repo_spec	A string identifying the GitHub repo or, alternatively, a GitHub file URL. Acceptable forms: Plain OWNER/REPO spec A blob URL, such as "https://github.com/OWNER/REPO/blob/REF/path/to/some/file" A raw URL, such as "https://raw.githubusercontent.com/OWNER/REPO/REF/path/to/some/file" In the case of a URL, the path, ref, and host are extracted from it, in addition to the repo_spec.
path	Path of file to copy, relative to the GitHub repo it lives in. This is extracted from repo_spec when user provides a URL.
save_as	Path of file to create, relative to root of active project. Defaults to the last part of path, in the sense of basename(path) or fs::path_file(path).
ref	The name of a branch, tag, or commit. By default, the file at path will by copied from its current state in the repo's default branch. This is extracted from repo_spec when user provides a URL.
ignore	Should the newly created file be added to .Rbuildignore?
open	Open the newly created file for editing? Happens in RStudio, if applicable, or via utils::file.edit() otherwise.
host	GitHub host to target, passed to the .api_url argument of gh::gh(). If unspecified, gh defaults to "https://api.github.com", although gh's default can be customised by setting the GITHUB_API_URL environment variable. For a hypothetical GitHub Enterprise instance, either "https://github.acme.com/api/v3" or "https://github.acme.com" is acceptable.

Value

A logical indicator of whether a file was written, invisibly.

Examples

if (FALSE) {
use_github_file(
  "https://github.com/r-lib/actions/blob/v1/examples/check-standard.yaml"
)

use_github_file(
  "r-lib/actions",
  path = "examples/check-standard.yaml",
  ref = "v1",
  save_as = ".github/workflows/R-CMD-check.yaml"
)
