Nix

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

Pass completions for fish aren't loaded or otherwise don't work. Pass completions do work in bash.

You can view my exact system config here (specifically: [pass](https://github.com/samhh/dotfiles/blob/340d38cda522df32be971d0b37b9f741ab3195bb/misc.nix#L

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

Describe the bug

Sometimes the typechecker can throw something like:

  = The type of the expression was expected to be `a`
  = The type of the expression was inferred to be `a`
  = These types are not compatible

it can actualy append when one is a type variable and the other one is a type identifier.

To Reproduce

let f : forall a. {_: a} -> {_: a} -> {_: a}

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

Running Nixpackgs on the examples/haskell-stack directory fails with error

Unable to find installation URLs for OS key: linux-aarch64-tinfo6

It seems that the Haskell toolchain cannot find binaries for the aarch64 architecture on Linux

Otherwise one might get an error like:

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

NoInput "You need to specify store paths either as stdin or as a cli argument"

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
