Re: Patch/feature proposal: "Source plugins"

Hi Luite, I was fully planning on a first version of the patch yesterday, but so far my efforts were thwarted by annoying problems with dynamic libraries (not -- directly -- related to the patch at all). I will try again today :) Edsko On Wed, Jun 26, 2013 at 8:51 AM, Luite Stegeman wrote:

Any news on this? I'd really like to have this in GHC 7.8.1 so that we can release a fully working GHCJS with GhcMake functionality based on it. I'd be happy to help write the patch.

Guys,

I'm not following the details here, but I'm open to suggestions (patches, even) that improve the GHC API.
