@sebmck also, babel doesn't appear to have an option to set the sourceMappingURL comment value, and it auto-decides to data-URI it.

@getify You can either set it to inline the entire source map or to just return it in the resulting result object under the `map` property.

@sebmck i'm talking about the //# sourceMappingURL=.. comment that's appended to the transpiled file. seems to always be a data-URI.

@getify It only appends the sourceMappingURL data URI comment when you have sourceMap set to inline.

@sebmck nope, also does it with "both"… at least here on my machine that i'm running right now.

@getify Ah yeah, "both" inlines it and returns the source map in the return object. Set it to true if you don't want the inlined comment.

@sebmck can't imagine any use-case for "both" that actually duplicates map data. assumed "both" returned map data and added URL comment

@getify https://github.com/babel/babel/pull/966 … When you set sourceMap to inline it doesn't return the map data. Sometimes you want both.
