This package provides a standalone executable called hdb which can be used to step-through Haskell programs and can act as a Debug Adapter Protocol (DAP) server in the server mode for debugging Haskell programs. . The Debug Adapter is implemented on top of the haskell-debugger library which defines the primitive debugging capabilities. These debugger features are implemented by managing a GHC session and debugging it through the GHC API. . The hdb is transparently compatible with most projects because it uses hie-bios to figure out the right flags to invoke GHC with. . Additional information can be found in the README.
