Disable browser prefixes in SASS Compass?

Question

Is there a way of disabling all of the browser prefixes that Compass adds?

Example;

.heartbeat {
  @include animation(heartbeat 0.5s linear infinite);
}

Generates this:

.heartbeat {
    -moz-animation    : heartbeat .5s linear infinite;
    -webkit-animation : heartbeat .5s linear infinite;
    animation         : heartbeat .5s linear infinite
}

But all I want is this:

.heartbeat {
    animation         : heartbeat .5s linear infinite
}

Yes, I could simply replace

.heartbeat {
  @include animation(heartbeat 0.5s linear infinite);
}

with

.heartbeat {
  animation(heartbeat 0.5s linear infinite);
}

But I would prefer not to modify the SASS code.

Answer 1

I solved it by doing:

compass interactive
browsers()

Got all supported browser:

("android", "android-chrome", "android-firefox", "blackberry", "chrome", "firefox", "ie", "ie-mobile", "ios-safari", "opera", "opera-mini", "opera-mobile", "safari")

And finally adding this to a sass-file:

$supported-browsers: reject(browsers(), "android", "android-chrome", "android-firefox", "blackberry", "chrome", "firefox", "ie", "ie-mobile", "ios-safari", "opera", "opera-mini", "opera-mobile", "safari");
