We should look up hsPkgs.${pkg-name}.components.exe.${component-name}
instead of including the package as a dependency.
Adding `hsPkgs.${pkg-name}` a tool it is not clear which executable in the package `haskell.nix` should choose.
Haskell.nix did not deal with this well and in fact it could lead to `nix-shell` crashing. For instance using `shellFor` to make a shell for building `haskell-language-server` with `cabal build` crashed as a dependency on `ghcide` the executable (by the `ghcide-bench` executable) caused infinite recursion. Allowing `ghcide-bench` to correctly depend just on `components.exes.ghcide` fixes this.
This PR also includes:
* Updated materialized files built with the new nix-tools and latest index-state
* Small update to GHCJS (pins happy) to fix issue that showed up when the materialization was updated
* A fix for the infinite recursion issue when updating materialized files (by adding ghc-boot-packages-unchecked).
* Performance fix for shellFor (checks just the names of component derivations when filtering).
Changes to the interface of haskell.nix (from the changelog.md file):
* Removed `sources.nixpkgs-default`, use `sources.nixpkgs` instead.
* Removed `./nixpkgs` directory, use `(import ./. {}).sources`
or `./nix/sources.nix` instead.
* Removes V1 interface for details on how to fix old code see:
https://github.com/input-output-hk/haskell.nix/issues/709
* Removed defaultCompilerNixName.
* cabalProject, cabalProject', hackage-project and hackage-package
now require a `compiler-nix-name` argument.
* `haskell-nix.tool` and `.tools` now require a `compiler-nix-name` argument.
New functions `p.tool` and `p.tools` (where p is a project) do not.
Like `shellFor { tools = ... }` they will use the compiler nix name
from the project (including stack projects where it is derived from
the resolver).
* `haskell-nix.alex` and `haskell-nix.happy` have been removed. Use
`p.tool "alex" "3.2.5"` or `shellFor { tools = { alex = "3.2.5"; } }`.
* `haskell-nix.nix-tools` -> `haskell-nix.nix-tools.ghc883` (it includes
the hpack exe now).
* `haskell-nix.cabal-install` ->
`p.tool "cabal" "3.2.0.0"` or `shellFor { tools = { cabal = "3.2.0.0"; } }`
* `haskell-nix.haskellNixRoots` -> `haskell-nix.roots ghc883` or `p.roots`
Other changes:
Adds hpack executable to the nix-tools derivations.
Adds a `cabal-hpack` test to make sure `hpack` works with
`cabalProject`.
Reduces the number of calls to `cabalProject` (particularly when
checking materialization), by giving internal tools a per-compiler
attribute.
Uses happy 1.19.12 when building newer ghc versions.
Updates cabal-install 3.2.0.0 to use the source from github that
is compatible with ghc 8.10.1.
Updates the docs for callCabalProjectToNix.
Adds a license mapping to fix a common warning.
* ghc 8.10
* Adds/Updates/Removes materialization files
* Disable one-shot-kqueue-on-macos patch on ghc-8.10
* Test ghc883 and ghc8101 but only with nix 20.03
* Various smaller fixes.
This should fix the infinite recursion issue with #654
