If you compare the old PHP-based code generators with the newer Haskell-based one's , the PHP-based code gen's have much more readable code.

One low hanging fruit is to replace the normal haskell

Is there an existing issue for this?

Issue description

I was using home-manager on macos mojave just fine. Since updating to the newest release wiped my /nix, I had to reinstall.

On a completely clean install now (enabled home-manager channel and installed it only), I get:

home-manager switch
error: flake 'path:/Users/virapto

deploying libraries can take a long time. One can easily skip this stage if we make it possible to save the deployed library state and pass it to dapp test:

1. Write a new little dapp helper script which is the dapp --library-addresses above
2. Make dapp build and dapp --make-library-state use this helper script instead
3. Allow a flag --state to be passed to dapp test (probably a

When applying a contract written as a record to a value, the implementation is mostly to merge the contract with the value (although with a few minor differences). If the value is not a record, then the error obtained is then Non-mergeable terms, which is slightly unintuitive.

That is, non-record contracts violation and recor

When trying out Niv and following the example from the readme to add GHC:

$ niv add ghc   \
    -v 8.4.3    \
    -t 'https://downloads.haskell.org/~ghc/<version>/ghc-<version>-i386-deb8-linux.tar.xz'

But instead using the latest ghc version (9.0.1 as of writing), I get the following error:

$ niv add ghc -v 9.0.1 -t 'https://downloads.haskell.org/~ghc/<version>/ghc-<versi

Otherwise one might get an error like:

cachix push /nix/store/7i1kqf6x52l1fhqqdmqgggjr0zigggik-cachix-0.1.3/bin/cachix

I'm wondering if it's possible with haskell.nix to generate HIE files for some component(s). These are explained here and allow you to do static analysis of Haskell code. In particular, they can be used to run weeder.

If you pass -fwrite-ide-info to GHC, it will emit these files. By defa
