Adding haskell-ide-engine to a project

[cfraz89]

Hi,

I'm attempting to add haskell-ide-engine to my project. It was recently added to NixPkgs, and hopefully reflex-platform's fork will include it soon. In the meantime, I've copied the package expression from here:

https://github.com/NixOS/nixpkgs/blob/89e882f956bcddf01ea2d69a569156bf93dcb9c6/pkgs/development/haskell-modules/hie-packages.nix

However my nix-foo isn't good enough to figure out how to invoke the package within the context of reflex-platform.

My shell.nix currently looks like this:

with import <nixpkgs> {};
with import ./reflex-platform {};

let
    hie-packages = ((callPackage ./hie-packages.nix {}) {}); 
    myProject = haskell.lib.addBuildTools (ghc.callPackage ./myProject.nix {}) [hie-packages.haskell-ide-engine];
in
workOn ghc myProject

However I believe the invocation of ((callPackage ./hie-packages.nix {}) {}); is wrong, as I get

error: anonymous function at /home/chris/Projects/myProject/hie-packages.nix:217:8 called without required argument ‘mkDerivation’, at /nix/store/m3il05py3idyf4ny154zjbq23f5blpxx-nixpkgs-18.03pre125635.846b5c42f19/nixpkgs/lib/customisation.nix:74:12

Any help with this would be greatly appreciated.

Additionally, it would be great to see hie integrated into reflex-platform :D

[sboosali]

try the .project nix helper function:

https://github.com/reflex-frp/reflex-platform/blob/develop/docs/project-development.md#building-with-nix

Which automatically parses dependencies from your .cabal files, like stack.

Here is an example that's working for me:

https://github.com/sboosali/cards/blob/master/default.nix

Since you want the executable, I think you can add a build tool too, with an override:

https://github.com/reflex-frp/reflex-platform/blob/develop/project/default.nix#L72

(Btw, I'm sure you can get it working more simply, but like you I don't know too much nix.)

[cfraz89]

Had a bit more luck using a hie derivation generated by https://github.com/input-output-hk/stack2nix. Now nix-shell works, however cabal can't find jsaddle-warp. I think somehow reflex's ghc is being overridden by hie's?

When attempting to pass reflex's ghc to the hie derivation: hie = reflex.ghc.callPackage ../../Downloads/haskell-ide-engine/hie.nix { compiler = reflex.ghc; };

I'm met with this error: error: attribute ‘overrides’ missing, at /home/chris/Projects/racebase-reflex/reflex-platform/default.nix:194:63

[pshemass]

i believe that haskell-ide-engine is already in reflex platform (line 417 in https://github.com/reflex-frp/reflex-platform/blob/develop/default.nix) in 0.6.0.0 version but still.

If you use Obelisk to update hie version to newest you could try

{ system ? builtins.currentSystem # TODO: Get rid of this system cruft
, iosSdkVersion ? "10.2"
}:
with import ./.obelisk/impl { inherit system iosSdkVersion; };
with import (fetchTarball https://github.com/domenkozar/hie-nix/tarball/master) {};

project ./. ({ ... }: {
  android.applicationId = "systems.obsidian.obelisk.examples.minimal";
  android.displayName = "Obelisk Minimal Example";
  ios.bundleIdentifier = "systems.obsidian.obelisk.examples.minimal";
  ios.bundleName = "Obelisk Minimal Example";
  shellToolOverrides = self: super: {
      haskell-ide-engine = hie84;
    };
})

Regarding obelisk + HIE

Trying to setup haskell-language-server but getting Multi Cradle: No prefixes matched

How to reproduce

1. on current master
2. hack-on will remove the nix-thunk files in dir and clone project instead to that dir

3. apply patch
