次のように、スタックを使用して Haskell プロジェクトを整理しています。
.
├── ProjectA
│ ├── Main.hs
│ ├── ProjectA.cabal
│ └── Setup.hs
├── ProjectB
│ ├── Main.hs
│ ├── ProjectB.cabal
│ └── Setup.hs
├── ProjectC
│ ├── Main.hs
│ ├── ProjectC.cabal
│ └── Setup.hs
└── stack.yaml
つまり、多くのディレクトリがあり、それぞれにパッケージが含まれており、それらを含む単一のスタック環境があります。ワークフロー中に、stack buildコンパイル エラーを取得し、作業をガイドするために を使用しています。問題は、適切なエラー メッセージを表示するのに時間がかかりすぎることと、編集したすべてのファイルのすべての依存関係を再構築することです。私はインタラクティブに作業するのが好きです。つまり、数行のコードを編集し、コンパイルし、繰り返します。常に一度に 1 つのファイルのみを編集します。これにより、ワークフローが大幅に遅くなります。
(グローバル インストールで)使用する前stackに、編集中のファイルに対して GHCI を実行するだけでしたが、それはもう機能しません。セットアップでエラー メッセージの取得を高速化する方法はありますか?
これは次の出力ですstack build --verbose。
