Source map rules

[attakei]

Overview

Support to pass arguments for source map rules.

Design

• SourceMapStyle = Literal:
  • normal: Generate source maps with default style.
  • none: Doesn't generate source map.
  • embed: Generate source maps with source.
• SourceMapUrl = Literal:
  • relative: Set relative URL.
  • absolute: Set absolute URL.
  • embed: Set data: prefixed URL.

When run for style.scss:

--no-source-map	--embed-source-map	--embed-sources	--source-map-urls	output.css	output.css.map
N	N	N	relative	With ref to source-map	created
N	N	N	absolute	With ref to source-map	created
N	N	Y	relative	With ref to source-map	created
N	N	Y	absolute	With ref to source-map	created
N	Y	N	relative	With source-map content	not created
N	Y	N	absolute	With source-map content	not created
N	Y	Y	relative	With source-map content	not created
N	Y	Y	absolute	With source-map content	not created
Y	-	-	--	Only style	not created

Note: output.css.map == created case is not working by STDOUT pattern.
