Re: [Haskell-cafe] ANN: The Herbie GHC Plugin

Thanks :) That's a good suggestion about not calling expressions improved when they're not. I've just pushed a new patch to the repo that fixes this issue. On Tue, Sep 22, 2015 at 12:48 PM, Edward Kmett wrote:

Okay. Having gone through and chewed on a bunch of the optimizations it has found, I have to say I officially absolutely adore this plugin!

It would be nice if it didn't report 'improved' expressions that are the same as the original, but everything else about it is amazing.

In this case the primary concern would be that Herbie really needs to have an install of racket as well to do its job right. Between that and a database, there are a lot of things that aren't usually involved in a normal GHC install.

Does GHC HQ consider the possibility of embedding/shipping plugins like this with normal releases?

Very nice!

Now I just need to figure out how to extract the results of these analyses and see if I can understand and apply them manually to what libraries of mine are affected, so that folks who won't or can't run this plugin can derive the benefits.

80% of packages in stackage that contain floating point expressions have numerically unstable expressions. The Herbie GHC plugin automatically makes these expressions numerically stable.
