Thank you to all the many candidates who submitted a self-nomination. We received a number of strong nominations. We would encourage all those who nominated themselves to consider self-nominating again in the future. The outgoing members are: John Wiegley and Alan Zimmerman. Thanks both for your service!

May be topic is not for Haskell beginners, so I'll re-send it to Cafe. I have function which constructs some data type. It has signature `Name -> Q [Dec]`. Somewhere in its body I'm extracting constructors of another type with pattern-matching: case tyCons of DataD ctx nm tyVars mbKind cs derivs -> ... Type of those constructors `cs` instantiates some class like this: class MyClass a where specialValue :: a So, I'm iterating over those `cs` but I want to skip one of them which is equal to `specialValue`. Something like this: [c | c <- cs, c /= specialValue] How to do this with Template Haskell's `Con` type (`c`::Con)? I can't simply call it to compare created value with a `specialValue`. === Best regards, Paul ------------------------------ Message: 3 Date: Mon, 11 Dec 2017 21:16:25 +0900 From: Takenobu Tani To: haskell-cafe Subject: [Haskell-cafe] Who can send a patche to vim project? Message-ID: Content-Type: text/plain; charset="utf-8" Hi cafe, Who can send a patche to vim project? I'd like to update vim syntax file (haskell.vim) to fix numeric literals. I read the vim `CONTRIBUTING.md` file [1]. It instructs me to contact the maintainer of each files. In the header of `haskell.vim`, the maintainor of `haskell.vim` is haskell-cafe@ML. [2] Who is the maintainer of `haskell.vim`? I'd like to make fix on numeric literals extension: [3] * BinaryLiterals * HexFloatLiterals * NumericUnderscores I prepared two kinds of patches. * Exact pattern version [4] * Fast (but approximate) pattern version [5] I visually checked patches with the these files [6][7]. Could you send a patch of [4] or [5] to vim project? P.S. I have already sent patches to two projects. * `language-haskell` for atom and linguist [8] You can already use it on atom. Linghist (which is used from github) will apply it soon. * `pygments` [9] It is pending review.
