output_template: An intelligent (temporary) output file

In sass: Syntactically Awesome Style Sheets ('Sass')

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)

Arguments

basename	a non-empty character vector giving the outfile name (without the extension).
dirname	a non-empty character vector 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".

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")
