output_template {sass}

An intelligent (temporary) output file

Description

Intended for use with sass()'s output argument for temporary file generation that is cache and options aware. In particular, this ensures that new redundant file(s) aren't generated on a sass() cache hit, and that the file's extension is suitable for the sass_options()'s output_style.

Usage

output_template(
  basename = "sass",
  dirname = basename,
  fileext = NULL,
  path = tempdir()
)

Arguments

basename

a non-empty character string giving the outfile name (without the extension).

dirname

a non-empty character string giving the initial part of the directory name.

fileext

the output file extension. The default is ".min.css" for compressed and compact output styles; otherwise, its ".css".

path

the output file's root directory path.

Value

A function with two arguments: options and suffix. When called inside sass() with caching enabled, the caching key is supplied to suffix.

Examples

sass("body {color: red}", output = output_template())

func <- output_template(basename = "foo", dirname = "bar-")
func(suffix = "baz")
