Haskell環境構築

参考にした記事

※ この手順はしない方が良いです。ghcupと競合します。上記の記事とは別の記事を参照して、ミスをした手順です。

必要そうなのをbrewで入れる

brew install ghc cabal-install stack

brewで入れちゃったけどghcupの方が良さそう(結果的にbrewで入れたものはuninstallしました)

curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh

実行結果

Welcome to Haskell!

This script can download and install the following binaries:
  * ghcup - The Haskell toolchain installer
  * ghc   - The Glasgow Haskell Compiler
  * cabal - The Cabal build tool for managing Haskell software
  * stack - A cross-platform program for developing Haskell projects (similar to cabal)
  * hls   - (optional) A language server for developers to integrate with their editor/IDE

ghcup installs only into the following directory,
which can be removed anytime:
  /Users/shuntaka/.ghcup

Press ENTER to proceed or ctrl-c to abort.
Note that this script can be re-run at any given time.

結果的に設定はしないほうがよかった。zshenvには以下のように自前で設定

https://github.com/shuntaka9576/dotfiles/blob/bf80432e875df87e35b4b2f38f9a63ecf9b3b048/zsh/.zshenv#L88-L90

末尾に入れて欲しいからAかな。

Detected zsh shell on your system...
Do you want ghcup to automatically add the required PATH variable to "/Users/shuntaka/.zsh/.zshrc"?

[P] Yes, prepend  [A] Yes, append  [N] No  [?] Help (default is "P").

mason経由で入れるのでN

Do you want to install haskell-language-server (HLS)?
HLS is a language-server that provides IDE-like functionality
and can integrate with different editors, such as Vim, Emacs, VS Code, Atom, ...
Also see https://haskell-language-server.readthedocs.io/en/stable/

[Y] Yes  [N] No  [?] Help (default is "N").

stackがghcupのghcバージョンを使用するか。よくわからないのでY。

Do you want to enable better integration of stack with GHCup?
This means that stack won't install its own GHC versions, but uses GHCup's.
For more information see:
  https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation-experimental
If you want to keep stacks vanilla behavior, answer 'No'.

[Y] Yes  [N] No  [?] Help (default is "Y").

これでインストールが始まる

System requirements
  Note: On OS X, in the course of running ghcup you will be given a dialog box to install the command line tools. Accept and the requirements will be installed for you. You will then need to run the command again.
On Darwin M1 you might also need a working llvm installed (e.g. via brew) and have the toolchain exposed in PATH.
Press ENTER to proceed or ctrl-c to abort.
Installation may take a while.

brewで入れたのが気がかりだけどうまくいっている気がする

!

zshに自動で記述された内容にミスがある

- [ -f "/Users/shuntaka/.ghcup/env" ] && . "/User/shuntaka/.ghcup/env" # ghcup-env
+[ -f "/Users/shuntaka/.ghcup/env" ] && . "/Users/shuntaka/.ghcup/env" # ghcup-env

これで良さそう

$ which stack
/Users/shuntaka/.ghcup/bin/stack

TODO
Neovim側で:Masonで、haskell-language-serverを選択

haskell-language-server入ったっぽい

stack new book

stack buildすると、最新のコンパイラを落としてきてよくわからないことになるので、以下の記述が必要

stack.yaml

+resolver: lts-20.11
+compiler: ghc-9.4.8

ghcup tuiはこの状態。基本的にrecommendにしている(25/01/06時点)

古いやつ(※ 24/06/24時点)

LSPを動いているけど、ghcup経由ではなくMason経由なのでバージョンが違うことによる問題が出そう 🤔
とりあえず今は動作しているから放置。

https://github.com/haskell/ghcup-hs

にしてもghcupがhaskell製なのすごいな…tuiが実装できている
LLVMバックエンド(?)だからここら辺クロスコンパイルできるのか 🤔

haskell-tools.nvim周りは未調査だけど、これはある程度言語触らないと必要が生まれないから一旦Closeしよう

フォーマッタの設定

stack install ormolu

formatter.nvimに設定

macでnvfetcherをビルドする際に、GNU gccが優先されてしまい、ハマったので、メモ。

cabal build --with-gcc=/usr/bin/clang --with-ld=/etc/profiles/per-user/shuntaka/bin/ld

と思ったら、オプションなくても成功するなぁ、、
