Haskell one-liners - lahteenmaki.net

One-liners to launch a complete Haskell development environment.

No dependencies needed except for Nix.

If you clone the repo and add it to a path, you can give the contents of PKGS simply as command line arguments.

Use ARGS environment variable to give extra arguments to nix-shell.

• Launch GHCi REPL.
• Give Haskell packages as PKGS environment variable.
• If the only parameter is a cabal file, the repl contains Haskell/system packages defined in the cabal file.
• If the only parameter is a Nix file, the repl contains environment defined in the Nix file.

• Launch a shell with GHC and Haskell development tools.
• Give Haskell packages as PKGS environment variable.
• If the only parameter is a cabal file, the shell contains Haskell development tools and GHC with Haskell/system packages defined in the cabal file.
• If the only parameter is a Nix file, the repl contains Haskell development tools and the environment defined in the Nix file.

• Launch a shell with GHCJS and Haskell development tools.
• Give Haskell packages as PKGS environment variable.
• If the only parameter is a cabal file, the shell contains Haskell development tools and GHCJS with Haskell/system packages defined in the cabal file.
• If the only parameter is a Nix file, the repl contains Haskell development tools and the environment (using GHCJS compiler) defined in the Nix file.

• Launch your default editor with GHC and Haskell development tools.
• Give Haskell packages as PKGS environment variable.
• If the only parameter is a cabal file, your default editor is opened in the parent folder with Haskell development tools and GHC with Haskell/system packages defined in the cabal file.
• If the only parameter is a Nix file, your default editor is opened in the parent folder with Haskell development tools and the environment defined in the Nix file.
