Haskell Debug Adapter.

Please see README.md

Haskell Debug Adapter

A debug adapter for Haskell debugging system.

Started development based on phoityne-vscode-0.0.28.0.
Changed package name (because a name "phoityne-vscode" is ambiguous.), and with some refactoring.

• Haskell Debugger

  • haskell-debug-adapter
    This library.
  • haskell-dap
    Haskell implementation of DAP interface data.
  • ghci-dap
    A GHCi having DAP interface.

• Debug adapter clients

  • phoityne-vscode(hdx4vsc)
    An extension for VSCode.
  • hdx4vim
    This is just a configuration for the vimspector which is a debug adapter client of Vim.
    See a sample configuration.
  • hdx4emacs
    This is just a configuration for dap-mode of Emacs.
    See a sample configuration.
  • hdx4vs
    An extension for Visual Studio.
  • haskell-tools.nvim A Neovim plugin that discovers launch configurations for nvim-dap from cabal and stack projects, and from Visual Studio Code launch.json files.

Requirement

• haskell-dap
• ghci-dap

Install these libraries at once.

> stack install haskell-dap ghci-dap haskell-debug-adapter

You can also build and run this project with nix:

> nix build .#haskell-debug-adapter

or

> nix run .#haskell-debug-adapter

Development

This project can be built with stack, cabal and nix.

To run all tests and checks with nix:

> nix flake check -L

To enter a development shell with nix:

> nix develop

Note

The stack.yaml and cabal.project assume that haskell-dap and ghci-dap are checked out in the same directory as this project. If they are not, haskell-language-server will fail to start.

Limitation

Currently this project is an experimental design and implementation.

• The source file extension must be ".hs"
• Can not use STDIN handle while debugging.
