Generated sprite variables have trailing comma

[tpgmartin]

Hey there,

Minor issue, but the individual image variables lists in the generated stylesheet - in my case SCSS - always have trailing commas before the closing bracket.

For instance,

$img: (0px, 0px, 0px, 0px, 87px, 14px, 122px, 108px, '/sprite.png', 'img', );

Cheers

This is expected behavior, the reason is we have lists of unknown length at other points (e.g. $sprites) and since we are using Handlebars, we cannot detect when we are at the last element in an each. As a result, we have a trailing comma in those locations.

The trailing comma in the posted example is to keep the file consistent with its trailing commas.

Thanks for your response, that's good to know

So there's no way to dealing with this?

I can't use Spritesmith with older versions of SASS (the one we have in our prod server).

This can be worked around via:

• Generating CSS content instead of SASS/SCSS content
• Writing/using a custom template

I wasn't aware there was a version of SASS that didn't support this. What's the SASS version?
