use_template: Use a usethis-style template

Description

Creates a file from data and a template found in a package. Provides control over file name, the addition to .Rbuildignore, and opening the file for inspection.

Usage

use_template(template, save_as = template, data = list(), ignore = FALSE,
  open = FALSE, package = "usethis")

Arguments

template

Path to template file relative to "templates" directory within package; see details.

save_as

Name of file to create. Defaults to template

data

A list of data passed to the template.

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.

package

Name of the package where the template is found.

Value

A logical vector indicating if file was modified.

Details

This function can be used as the engine for a templating function in other packages. The template argument is used along with the package argument to determine the path to your template file; it will be expected at system.file("templates", template, package = package).

To interpolate your data into the template, supply a list using the data argument. Internally, this function uses whisker::whisker.render() to combine your template file with your data.

Examples

Run this code

# NOT RUN {
  # Note: running this will write `NEWS.md` to your working directory
  use_template(
    template = "NEWS.md",
    data = list(Package = "acme", Version = "1.2.3"),
    package = "usethis"
  )
# }
