Hi John, > Peter, did you it move [the repository] to someplace else? I have re-created the repository at . Originally, I attempted to parse Nix with Parsec, and I got quite far. The code in 'master' can parse almost all of "all-packages.nix" correctly. At s

Re: [Nix-dev] Writing a Nix evaluator in Haskell

Hah, I also started to write a parser for nix expressions as an exercise! But now that there is already a parser, I'll probably just use yours. -- Benno 2014-06-29 16:37 GMT+02:00 Oliver Charles : > On 29/06/14 01:03, John Wiegley wrote: > > Since the Nix language is such a nice and simple pur

Wow John you weren't kidding just a few hours ago. Good luck with the project, was hoping to see a Quickcheck tests directory. Aloha, RK. On Sun, Jun 29, 2014 at 10:03 AM, John Wiegley wrote: > Since the Nix language is such a nice and simple pure functional language, > I > thought it would

[Nix-dev] Writing a Nix evaluator in Haskell

Since the Nix language is such a nice and simple pure functional language, I thought it would be nice to have tooling support for it in Haskell, to aid writing lint utilities, etc. As such, I've started a project call hnix which will implement a parser and evaluator for Nix in Haskell. I have the
