I think supporting both Sass v3.3.x and v3.4.x is very hard. dargs package used in this Grunt plugin does not support argument option separated by =. And Sass's default behavior changes to generate Source Maps if this option is not set.
I've patched by hand, but this cannot make tests pass.
Looks like with Sass 3.4 (it’s at RC 3 at the moment), the sourcemap CLI option has to be passed with the equals sign.
needs to be updated to:
Looks like the other valid options are
--sourcemap=file
,--sourcemap=inline
, and--sourcemap=none
.
