update to libsass 3.2.0-beta.4

[fsmanuel]

Hey thanks for the great work.
I run into 'Support parent selector & in values / and/or interpolations' (sass/libsass#548). That seems to be fixed in libsass 3.2.0-beta.4.
Anything I can do to help with a new release that includes libsass 3.2.0-beta.4?

@fsmanuel, thanks for the offer. I have a very busy week going on. The only stopper is the recent changes in importer. I will try to spend sometime over the weekend.

@mgreter, here are the changes I was referring to: am11@55aadd2. It throws at line 11 because Sass_Compiler (comp) is null with the following test:

// in node-sass dir
require('./').render({
  data: '@import \'doesNotExist.scss\'',
  importer: function(url, prev, done) {
    done({file: url, contents: 's { a: ss; }'});
  }
}, function(err, result){
  if(err) {
    console.log(err); return;
  }

  console.log(result, result.css.toString());
});

(hopefully missing something fundamental and not the bug in libsass..)

Note this is the first step to make the previous implementation just work. Once this passes the existing test suite, I will modify it for multi importers support.

Can't wait to try libsass 3.2.0-beta4

Libsass beta4 had a bug which is fixed in their master. We are waiting on the next nightly.

v3.0.0-beta.5 is released pointing to libsass v3.2.0-beta.5: https://github.com/sass/node-sass/releases/tag/v3.0.0-beta.5.

Yay! Great work everyone

Thanks! Much better now but still not quite working. Specifically, singularitygs doesn't compile yet due to using negative numbers in map's keys: sass/libsass#1086
