Initialize vouch in the current project

Creates a starter VOUCHED.td file at .github/VOUCHED.td and ensures .github is ignored in package builds by adding ^\\.github$ to .Rbuildignore when needed.

Usage

use_vouch()

Value

Invisibly returns NULL. Called for the side effects of writing a starter VOUCHED.td file and updating .Rbuildignore.

Details

If a vouch file already exists (VOUCHED.td or .github/VOUCHED.td), this function exits without making changes.

Examples

if (FALSE) { # \dontrun{
project <- file.path(tempdir(), "voucher-use-vouch-example")
dir.create(project, recursive = TRUE)
old <- setwd(project)
on.exit(setwd(old), add = TRUE)
use_vouch()
} # }
