Specify compiler options for sass(). To customize options, either provide sass_options() directly to a sass() call or set options globally via sass_options_set(). When shiny::devmode() is enabled, sass_options_get() defaults source_map_embed and source_map_contents to TRUE.

sass_options(
  precision = 5,
  output_style = "expanded",
  indented_syntax = FALSE,
  include_path = "",
  source_comments = FALSE,
  indent_type = "space",
  indent_width = 2,
  linefeed = "lf",
  output_path = "",
  source_map_file = "",
  source_map_root = "",
  source_map_embed = FALSE,
  source_map_contents = FALSE,
  omit_source_map_url = FALSE
)

sass_options_get(...)

sass_options_set(...)

Arguments

precision

Number of decimal places.

output_style

Bracketing and formatting style of the CSS output. Possible styles: "nested", "expanded", "compact", and "compressed".

indented_syntax

Enables the compiler to parse Sass Indented Syntax in strings. Note that the compiler automatically overrides this option to TRUE or FALSE for files with .sass and .scss file extensions respectively.

include_path

Vector of paths used to resolve @import. Multiple paths are possible using a character vector of paths.

source_comments

Annotates CSS output with line and file comments from Sass file for debugging.

indent_type

Specifies the indent type as "space" or "tab".

indent_width

Number of tabs or spaces used for indentation. Maximum 10.

linefeed

Specifies how new lines should be delimited. Possible values: "lf", "cr", "lfcr", and "crlf".

output_path

Specifies the location of the output file. Note: this option will not write the file on disk. It is only for internal reference with the source map.

source_map_file

Specifies the location for Sass to write the source map.

source_map_root

Value will be included as source root in the source map information.

source_map_embed

Embeds the source map as a data URI.

source_map_contents

Includes the contents in the source map information.

omit_source_map_url

Disable the inclusion of source map information in the output file. Note: must specify output_path when TRUE.

...

arguments to sass_options(). For sass_options_set(), the following values are also acceptable:

  • NULL, clearing the global options.

  • Return value of sass_options_get().

  • Return value of sass_options_set().

Value

List of Sass compiler options to be used with sass(). For sass_options_set(), any previously set global options are returned.

Examples

x <- "foo { margin: 122px * .001; }" sass(x)
#> /* CSS */ #> foo { #> margin: 0.122px; #> } #>
# Provide options directly to sass() sass(x, options = sass_options(precision = 1, output_style = "compact"))
#> /* CSS */ #> foo { margin: 0.1px; } #>
# Or set some option(s) globally old_options <- sass_options_set(precision = 1) sass(x)
#> /* CSS */ #> foo { #> margin: 0.1px; #> } #>
# Specify local options while also respecting global options sass(x, options = sass_options_get(output_style = "compact"))
#> /* CSS */ #> foo { margin: 0.1px; } #>
# Restore original state sass_options_set(old_options)
