My開発メモHaskellのインストール
今使っている方法
現在は、以下の方法で haskellをインストールして使っている。
haskellのインストール
$ sudo apt update
$ sudo apt install ghcこの方法でしばらく使っていたのだが、”パッケージ random” をインストールしようとして、
はたと困った。
ネットでやり方を調べても、stackを使うか、ghcupを使うか、それしか情報がなかった。
（もっと調べたらあるんだろうけれど・・・）
ということで、以前のやり方でインストールし直した。
$ sudo apt purge ghc
$ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | shEmacsにhaskell-modeをインストールする
M-x list-package
にて、haskell-mode をインストールする。これだけ。
参考
haskell-mode ( https://github.com/haskell/haskell-mode ) の 「Quick Installation」の項目を参照。
以前に書いた内容 (以前は、以下のように haskellをインストールした。)
純粋関数型言語ということで、一度さわっておきたいので、インストールした。
インストールのためのサイト
https://www.haskell.org/ghcup/
インストール
ターミナルにて以下を実行した。
$ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh以下のように出力された。
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:
/home/se-ichi/.ghcup
Press ENTER to proceed or ctrl-c to abort.
Note that this script can be re-run at any given time.Enterを入力した。
------------------------------------------------------------------------------
Detected bash shell on your system...
Do you want ghcup to automatically add the required PATH variable to "/home/se-ichi/.bashrc"?
[P] Yes, prepend [A] Yes, append [N] No [?] Help (default is "P").「A」を入力した。
------------------------------------------------------------------------------
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").「Y」を入力した。
------------------------------------------------------------------------------
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").「Y」を入力した。

All done!
To start a simple repl, run:
ghci
To start a new haskell project in the current directory, run:
cabal init --interactive
